Critically Endangered North Atlantic Right Whale Baby Found Dead in North Carolina
25 November

An extremely rare North Atlantic right whale calf was found dead off the North Carolina coast on Friday.
<p>The male calf was also the first documented birth this calving season, a development the National Oceanic and Atmospheric Administration (NOAA) called devastating.</p><p>"Each new right whale calf brings so much hope for this critically <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered species</a>, and losses like this have a substantial impact on their recovery," NOAA wrote in a <a href="https://www.fisheries.noaa.gov/feature-story/first-known-north-atlantic-right-whale-calf-season-washes-dead-north-carolina" target="_blank">press release</a>.</p><p>National Park Service workers discovered the <a href="https://www.ecowatch.com/tag/whales" target="_self">whale</a> on <a href="https://npplan.com/parks-by-state/north-carolina-national-parks/cape-lookout-national-seashore-park-at-a-glance/cape-lookout-national-seashore-the-islands/cape-lookout-national-seashore-north-core-banks/" rel="noopener noreferrer" target="_blank">North Core Banks</a>, the northernmost of three barrier islands that comprise the Cape Lookout National Seashore in North Carolina. On Saturday, a team of biologists came to conduct a necroscopy on the animal and take a DNA sample in order to determine its mother, Cape Lookout National Seashore explained on its <a href="https://www.facebook.com/CapeLookoutNPS/posts/3608024915884969" rel="noopener noreferrer" target="_blank">Facebook page</a>.</p><p>"Right Whales are critically endangered and are one of the rarest marine mammals," the seashore wrote.</p>
<div class="rm-shortcode" data-rm-shortcode-id="24c36ab7f041f96875677ba1e9dc1944"><div class="fb-post" data-href="https://www.facebook.com/CapeLookoutNPS/posts/3608024915884969"></div></div>
<p>The cause of death is not yet known, but NOAA said that there was no evidence human activity was a factor, <a href="https://edition.cnn.com/2020/11/23/us/rare-right-whale-washed-ashore-trnd/index.html" target="_blank">CNN reported</a>. Initial reports suggest the baby died either during birth or soon after.</p><p>The sad discovery comes little less than a month after a <a href="https://www.ecowatch.com/endangered-right-whale-population-2648532928.html" target="_self">grim NOAA report</a> found there are no more than 366 North Atlantic right whales left. The whales have been suffering from an "unusual mortality event" since 2017, NOAA said Monday. The agency has documented at least 32 deaths and 13 injuries during this event, more than 10 percent of the whales' remaining population. The leading causes of these deaths are vessel strikes and entanglements in <a href="https://www.ecowatch.com/tag/fishing" target="_self">fishing</a> gear.</p><p>The endangered whales also struggle to reproduce. Female whales give birth to only five or six calves per year, according to the Cape Lookout National Seashore. There are about 100 female whales left, CNN reported.</p>
<p>Female right whales usually reach maturity after 10 years and then give birth every three to five years. However, in recent years, the time between births has increased to six to 10 years. Scientists think that females are giving birth less often partly because of the stress of getting entangled in fishing gear. There have been just 22 births total during the past three calving seasons, about one-third of the previous annual average.</p><p>The right whale calving season extends from mid-November to mid-April. In winter, the whales migrate more than 1,000 miles from the waters of Canada and New England to warmer waters around South Carolina, Georgia and Florida's east coast, NOAA <a href="https://www.fisheries.noaa.gov/news/watching-migrating-right-whales-more-important-ever" target="_blank">said</a>. This is also where they give birth and nurse their young. NOAA urged boaters and fishers to watch out for the whales as their migration begins.</p>"NOAA is cautioning all boaters to be vigilant, slow down, and give these endangered whales plenty of room," NOAA wrote. "This will avoid accidental collisions and disturbing the whales as they migrate south. The agency is also asking fishermen to remove their unused gear from the <a href="https://www.ecowatch.com/tag/ocean" target="_self">ocean</a> to help avoid entanglements. Vertical lines with required markings, weak links, and breaking strengths are also required by law."

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.
<p>Here you can learn about the importance of organic hemp oil, why it's better for the environment, and which CBD companies actually make trustworthy products with sustainable farming processes. origins which weigh heavily on many consumers who want to buy a product that's produced in the best way possible for not only themselves to ingest, but for the environment as well through sustainable farming methods. </p><h2>What Is CBD Oil?</h2><p>First things first, CBD stands for cannabidiol, and it's a cannabinoid found within cannabis sativa plants. This plant compound is believed to have many potential benefits, and it is primarily derived from hemp plants via a CO2 extraction process. </p><p>Since CBD is extracted from industrial hemp, which contains only trace amounts of THC (the psychoactive component in cannabis plants), this means that CBD won't make you feel high like marijuana, which has much higher levels of THC that causes psychoactive effects. Instead, the effects of CBD are much more subtle and promote a general sense of calm and relaxation in most users.</p><h2>What Makes a CBD Oil Organic?</h2><p>In terms of organic labels, perhaps the most important (and prominent) certification comes from the United States Department of Agriculture (USDA). This government organization has been labeling foods as "organic" for many years, but what exactly does this certification entail? Essentially, a label indicating that a product is "USDA Organic" or "Certified Organic" means that at least 95% of the ingredients are obtained from organic sources.</p><p>For a crop to be considered organic by the USDA, it must be grown without the use of industrial solvents, irradiation, genetic engineering (GMOs), synthetic pesticides, or chemical fertilizer. Instead, farmers rely on natural substances and <a href="https://www.usda.gov/media/blog/2012/03/22/organic-101-what-usda-organic-label-means" rel="noopener noreferrer" target="_blank">mechanical, physical, or biologically based farming</a> techniques to cultivate healthy and organic crops.</p><p>Before the passage of the 2018 Farm Bill, no hemp-derived products could be dubbed as "certified organic" since the hemp plant and its extracts were still categorized as a Schedule I Controlled Substance. However, it's still difficult for CBD companies to obtain a USDA certified organic label for their products due to the legal grey area that still surrounds CBD extracts. </p><p>Because of these challenges, and due to the fact that industrial hemp has only recently become an agricultural crop, very few CBD oils are USDA certified organic. Rather, many CBD products contain hemp extracts from plants that were grown in organic conditions but may not be federally certified.</p><h2>What are the Best Organic CBD Oil Brands?</h2><p><em>Each product featured here has been independently selected. If you make a purchase using the links included, we may earn commission.</em></p>
<h2>Why Organic Hemp Oil Matters</h2><p>Hemp is a unique plant, not only for its rich cannabinoid content, but also for its ability to absorb a wide variety of components in soil. But this trait poses great risks when it comes to the creation of CBD products derived from hemp.</p><p>Because hemp has a high capacity for compound uptake, this means that the plants can retain <a href="https://www.remedyreview.com/industry/lab-test-results/" target="_blank">harmful chemicals like pesticides</a>, heavy metals, and other residual solvents. This is especially true when it comes to synthetic chemicals that are more toxic to humans, and difficult to remove once they have been absorbed by the hemp plant.</p><p>Organic farming practices help reduce the risk of hemp crops absorbing harsh chemicals that may later end up in CBD oil after extraction. When you're taking CBD as a wellness supplement to help alleviate your symptoms or improve your overall well-being, the last thing you want is to ingest compounds that might negatively outweigh the benefits of CBD. This is an important reason to look for third party lab test results when shopping for CBD products since these certificates of analysis can show the full cannabinoid and terpene profile of a hemp extract, as well as test results that search for the presence of any residual solvents.</p><p>In addition to creating a better end product, organic farming practices are also better for the environment. Sustainable and organic farming methods may <a href="https://www.helpguide.org/articles/healthy-eating/organic-foods.htm" rel="noopener noreferrer" target="_blank">reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy</a>. The use of natural pest deterrents as opposed to chemical pesticides is also better for nearby animal populations and ecosystems.</p><h3>Organic vs. Natural</h3><p>While there are only a select few companies offering certified organic ingredients in their products, almost every brand in the CBD market creates "natural" products. The term "all-natural" or "plant-based" does not mean that a product is organic, and since hemp oil is a natural derivative of hemp plants, these products are often referred to as all-natural. However, there are some synthetic CBD oils that should be avoided because they are chemically constructed and may produce unwanted side effects that are not caused by naturally derived CBD extracts.</p><h2>What are the Benefits of Organic CBD Oil?</h2><p>There's a long list of potential CBD oil health benefits, and some of the most common wellness advantages include:</p><ul class="ee-ul"><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2503660/" target="_blank">Chronic pain relief</a></li><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4604171/" target="_blank">Anti-anxiety effects</a></li><li>Better sleep</li><li><a href="https://www.psychologytoday.com/us/blog/inner-source/201901/cbd-oil-mental-health-should-you-take-it-too" rel="noopener noreferrer" target="_blank">Improvements in mood</a></li><li>Internal balance and regulation</li></ul><p>When dealing with pain, inflammation, sleep issues, and mental health struggles, it can be hard to find sufficient treatment options. The use of certain prescriptions can cause unwanted side effects, yet they are often the only solution for patients with these medical conditions. In search of other therapies, people have started to flock towards CBD oil as an alternative remedy for a variety of conditions. However, it should be noted that CBD products are not approved by the Food and Drug Administration (FDA), and you should seek your doctor's advice before using CBD if you have a serious medical condition.</p><h2>Look at the Labels Before You Buy CBD Oil</h2><p>When you go online to buy CBD oil, you'll quickly realize there is an overwhelming number of brands that are saturating the market. It can be difficult to determine which products are truly as good as they make themselves out to be. Always look for up-to-date third-party lab tests so you know you are getting a great product, and don't hesitate to contact the brand if you have any additional questions. And if you're intent on purchasing 100% organic CBD oil, it's best to look for certified products or brands that are held to strict regulatory standards.</p><p><strong>Melena Gurganus </strong>is the Reviews Editor at EcoWatch.

A fish farm off the coast of Tasmania. CW03070 / E+ / Getty Images
Around 50,000 farmed salmon swam free on Monday after a fire melted part of their enclosure off the coast of Tasmania.
<p>The salmon's escape has prompted concerns from local environmentalists, who are worried about the impact of the farmed fish on native <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> and ecosystems. While the farm's owners insist that impact will be minimal and the fish will be quickly eaten by seals or caught by recreational fishers, others disagree.</p><p>"It's like claiming a sewage spill is all good because it releases nutrients into the food chain," <a href="https://neighboursoffishfarming.org.au/" target="_blank">Neighbours of Fish Farming</a> president Peter George told <a href="https://www.theguardian.com/australia-news/2020/nov/24/fears-for-environment-after-50000-fish-escape-salmon-farm-in-tasmania" rel="noopener noreferrer" target="_blank">The Guardian</a>.</p>
<p>The fire that allowed the fish to escape broke out early Monday morning at an offshore enclosure owned by Huon Aquaculture, <a href="https://www.abc.net.au/news/2020-11-23/salmon-breakout-after-fire-huon-aquaculture-tasmania/12912222" target="_blank">Australia's ABC News reported</a>. The fire damaged about a third of a pen by burning and melting the pen both above and below the waterline, allowing the fish to escape. The company estimates that between 50,000 and 52,000 fish weighing four kilograms (approximately 8.8 pounds) each got away.<br></p><p>Huon Aquaculture does not yet know what caused the blaze.</p><p>"We have electrical equipment on our pens but in 35 years of farming we have never had an electrical fire on a fish pen so the cause has baffled us," CEO Peter Bender told the <a href="https://www.portnews.com.au/story/7025098/fish-farm-fire-sets-52k-salmon-free-in-tas/" target="_blank">Australian Associated Press</a>.<br></p>
<p>The escaped fish account for less than one percent of Huon's stocks, and the company has no plans to recapture them, according to The Guardian. But company representatives were confident the fish would not harm Tasmanian ecosystems.</p><p>Pene Snashall, the corporate communications and community relations manager at Huon Aquaculture, pointed to a 2018 <a href="https://www.imas.utas.edu.au/" target="_blank">Institute for Marine and Antarctic Studies</a> (IMAS) report that found that escaped farmed fish tend not to eat native fauna.</p><p>"Farmed salmon generally don't appear to feed on native species. While some fish did survive for some months, this did not necessary mean that these fish were thriving," Snashall told The Guardian.</p>
<p>But environmentalists disagreed.</p><p>"One IMAS [Institute for Marine and Antarctic Studies] study found 15% of escaped salmon lived off wild fish – that's 7,800 from just this escape, and they happen regularly," Laura Kelly of <a href="https://www.et.org.au/" rel="noopener noreferrer" target="_blank">Environment Tasmania</a> told The Guardian. "Then there's the animal welfare issues – with thousands of animals just starving to death. Huon needs to follow global investment patterns and get their feedlots out of the ocean and onto land."</p><p>And competition for food is not the only concern.</p><p>"There is also the worry these introduced species will [be] establishing populations in the wild," Dr. Christine Materia, also of Neighbours of Fish Farming, told <a href="https://www.abc.net.au/news/2020-11-24/salmon-escaped-from-fish-farm-caught-by-tasmanian-anglers/12914804" target="_blank">ABC News</a>.</p>
<p>IMAS associate professor Jeremy Lyle said that evidence did show that the impact of fish farm escapes like this one was "not that significant," but he also said any release of non-native species could pose problems.</p><p>"Any event like this is of some concern," he told ABC News. "Keeping introduced animals contained is more desirable."</p><p>The escape has brought out lots of recreational fishing aficionados to try and catch some of the salmon. Materia thought the company should compensate them for their efforts at containing the escape. Lyle, meanwhile, asked anyone who caught a fish to report the contents of its stomach to IMAS for research.</p>

Seagrass: Another Vital Carbon-Sequestering Ecosystem Threatened by Climate Change
24 November

By Melissa Gaskill
Two decades ago scientists and volunteers along the Virginia coast started tossing seagrass seeds into barren seaside lagoons. Disease and an intense hurricane had wiped out the plants in the 1930s, and no nearby meadows could serve as a naturally dispersing source of seeds to bring them back.
<p>The seeding effort eventually delivered more than 70 million seeds — and it paid off, creating some 9,000 acres of the underwater plants.</p>

</div></blockquote></div><p>Now monitoring of these restored meadows reveals multiple benefits to their restoration, including substantial increases in fish and invertebrate abundance, improved water clarity, and significant trapping of carbon and nitrogen.</p><p>"Planting adult seagrass is very labor intensive, but we started looking at using seeds in the lab and found it was quite easy," said biologist Robert "JJ" Orth, lead author on a new <a href="https://advances.sciencemag.org/content/6/41/eabc6434" target="_blank">paper</a> about the project. "These areas have good water quality, are shallow and are near the ocean so they get bathed in cooler water — perfect conditions. It was a surprise how quickly it happened."</p>

<p>The paper is part of a growing trend of evidence suggesting seagrass meadows can be easier to restore than other coastal habitats.</p><p>Successful seagrass-restoration methods include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0304377099000078?via%3Dihub" target="_blank">transplanting shoots</a>, <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1061-2971.2004.00314.x" target="_blank" rel="noopener noreferrer">mechanized planting</a> and, more recently, <a href="https://www.nature.com/articles/s41467-020-17438-4" target="_blank" rel="noopener noreferrer">biodegradable mats</a>. Removing threats, proximity to donor seagrass beds, planting techniques, project size and site selection all play roles in a restoration effort's success.</p><p>Human assistance isn't always necessary, though. In areas where some beds remain, seagrass can even recover on its own when stressors are reduced or removed. For example, seagrass began to recover when Tampa Bay improved its water quality by reducing nitrogen loads from runoff by roughly 90%.</p><p>But more and more, seagrass meadows struggle to hang on.</p><p>The marine flowering plants have declined globally since the 1930s and currently disappear at a rate equivalent to a football field every 30 minutes, according to the <a href="https://www.unep.org/resources/report/out-blue-value-seagrasses-environment-and-people" target="_blank" rel="noopener noreferrer">United Nations Environment Programme</a>. And research published in 2018 found the rate of decline is <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018GB005941" target="_blank" rel="noopener noreferrer">accelerating</a> in many regions.</p><p>The causes of decline vary and overlap, depending on the region. They include thermal stress from climate change; human activities such as dredging, anchoring and coastal infrastructure; and intentional removal in tourist areas. In addition, increased runoff from land carries sediment that clouds the water, blocking sunlight the plants need for photosynthesis. Runoff can also carry contaminants and nutrients from fertilizer that disrupt habitats and cause algal blooms.</p><p>All that damage comes with a cost.</p>The Value of Seagrass
<p>As with ecosystems like rainforests and <a href="https://therevelator.org/mangroves-climate-change/" target="_blank">mangroves</a>, loss of seagrass increases carbon dioxide emissions. And that spells trouble not just for certain habitats but for the whole planet.</p><p>Although seagrass covers at most 0.2% of the seabed, it <a href="https://www.unenvironment.org/news-and-stories/story/seagrass-secret-weapon-fight-against-global-heating" target="_blank">accounts for 10%</a> of the ocean's capacity to store carbon and soils, and these meadows store carbon dioxide an estimated 30 times faster than most terrestrial forests. Slow decomposition rates in seagrass sediments contribute to their <a href="https://www.researchgate.net/publication/238506081_Assessing_the_capacity_of_seagrass_meadows_for_carbon_burial_Current_limitations_and_future_strategies" target="_blank" rel="noopener noreferrer">high carbon burial rates</a>. In Australia, according to <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.15204" target="_blank" rel="noopener noreferrer">research</a> by scientists at Edith Cowan University, loss of seagrass meadows since the 1950s has increased carbon dioxide emissions by an amount equivalent to 5 million cars a year. The United Nations Environment Programme reports that a 29% decline in seagrass in Chesapeake Bay between 1991 and 2006 resulted in an estimated loss of up to 1.8 million tons of carbon.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDgwMzMxOS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0MDk0NDAwOX0.ILZN1S7VzsMsdiF6usSunDgL0wYRlgtFEoLb5Hinwq4/img.jpg?width=980" id="3b37c" class="rm-shortcode" data-rm-shortcode-id="06cc09d311c7b9b0d90ae063f04bbb5b" data-rm-shortcode-name="rebelmouse-image" />

<p>Seagrasses also protect costal habitats. A healthy meadow slows wave energy, reduces erosion and lowers the risk of flooding. In Morro Bay, California, a 90% decline in the seagrass species known as eelgrass caused extensive erosion, according to a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0272771420303528?via%3Dihub" target="_blank" rel="noopener noreferrer">paper</a> from researchers at California Polytechnic State University.</p><p>"Right away, we noticed big patterns in sediment loss or erosion," said lead author Ryan Walter. "Many studies have shown this on individual eelgrass beds, but very few studies looked at it on a systemwide scale."</p><p>In the tropics, seagrass's natural protection can reduce the need for expensive and often-environmentally unfriendly <a href="https://www.nioz.nl/en/news/zeegras-spaart-stranden-en-geld" target="_blank" rel="noopener noreferrer">beach nourishments</a> regularly conducted in tourism areas.</p><p>Seagrass ecosystems improve water quality and clarity, filtering particles out of the water column and preventing resuspension of sediment. This role could be even more important in the future. By producing oxygen through photosynthesis, meadows could help offset decreased oxygen levels caused by warmer water temperatures (oxygen is less soluble in warm than in cold water).</p><p>The meadows also provide vital habitat for a wide variety of marine life, including fish, sea turtles, birds, marine mammals such as manatees, invertebrates and algae. They provide nursery habitat for <a href="https://wedocs.unep.org/bitstream/handle/20.500.11822/32636/seagrass.pdf?sequence=1&isAllowed=y" target="_blank" rel="noopener noreferrer">roughly 20%</a> of the world's largest fisheries — an <a href="https://www.floridamuseum.ufl.edu/science/seagrass-meadows-harbor-wildlife-for-centuries/" target="_blank" rel="noopener noreferrer">estimated 70%</a> of fish habitats in Florida alone.</p><p>Conversely, their disappearance can contribute to die-offs of marine life. The loss of more than 20 square miles of seagrass in Florida's Biscayne Bay may have helped set the stage for a widespread <a href="https://www.wlrn.org/2020-08-14/the-seagrass-died-that-may-have-triggered-a-widespread-fish-kill-in-biscayne-bay" target="_blank">fish kill</a> in summer 2020. Lack of grasses to produce oxygen left the basin more vulnerable when temperatures rose and oxygen levels dropped as a result, says Florida International University professor Piero Gardinali.</p>Damaged Systems, a Changing Climate
<p>Governments and conservationists around the world have already put a lot of effort into coastal restoration efforts. And that's helped some seagrass populations.</p><p>Where stressors remain, though, restoration grows more complicated. <a href="https://www.rug.nl/research/portal/en/publications/the-future-of-seagrass-ecosystem-services-in-a-changing-world(3a8c56db-7bed-4c9e-ac7f-c72453e2a102).html" target="_blank">Research</a> published this September found that only 37% of seagrass restorations have survived.

<p>In Chesapeake Bay a cold-water species of seagrass is currently hitting its heat limit, especially in summer, according to Alexander Challen Hyman of University of Florida's School of Natural Resources and Environment. As waters continue to warm due to climate change, the species likely will disappear there.</p><p>Climate-driven sea-level rise complicates the problem as well. Seagrasses thrive at specific depths — too shallow and they dry out or are eaten, too deep and there isn't enough light for photosynthesis.</p>But There’s Good News, Too
<p>Luckily, left to its own devices, a seagrass meadow can flourish for hundreds of years, according to a <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2019.1861" target="_blank" rel="noopener noreferrer">paper</a> published last year by Hyman and other researchers from the University of Florida. The researchers arrived at their conclusion by looking at shells of living mollusks and fossil shells to estimate the ages of meadows in Florida's Big Bend region on the Gulf Coast.</p><p>That area has extensive, relatively pristine seagrass meadows. "Our motivation was to understand the past history of these systems, and shells store a lot of history," said co-author Michal Kowalewski.</p><p>A high degree of similarity between living and dead shells indicates a stable area, while a mismatch suggests an area shifted from seagrass to barren sand. The researchers found that long-term accumulations of shells resembled living ones, suggesting that the seagrass habitats have been stable over time.</p><p>That stability allows biodiversity to thrive, creating conditions where specialist species can survive and flourish, according to Hyman.</p><p>Discovering the long-term stability of seagrass meadows has implications for choosing restoration sites, Kowalewski notes.</p><p>"There must be reasons they thrive in one place, while a mile away they don't and fossil data says they probably never did," he said. "If we remove a seagrass patch, we cannot hope to plant it somewhere else. It's not just the seagrass that is special. The location at which it's found is special, too."</p><p>A better approach is conserving these habitats in the first place, but we're not doing enough of that right now. The UN reports that marine protected areas safeguard just 26% of recorded seagrass meadows, compared with 40% of coral reefs and 43% of mangroves.</p><div id="0e43d" class="rm-shortcode" data-rm-shortcode-id="5dd416de57a6668bb7b310f46cb45a94"><blockquote class="instagram-media"

Cyclone Gati on Sunday had sustained winds of 115 miles per hour. NASA - EOSDIS Worldview
Cyclone Gati made landfall in Somalia Sunday as the equivalent of a Category 2 hurricane, the first time that a hurricane-strength storm has made landfall in the East African country, NPR reported.
<p>Furthermore, at one point before making landfall, Gati strengthened to sustained winds of 115 miles per hour, the equivalent of a Category 3 storm. It is the strongest storm on record for the entire geographical area.</p><p>"Gati is the strongest tropical cyclone that has been recorded in this region of the globe; further south than any category 3-equivalent cyclone in the North Indian Ocean," National Oceanic and Atmospheric Administration (NOAA) researcher Sam Lillo <a href="https://twitter.com/splillo/status/1330554977870200838" target="_blank">tweeted</a>.</p>

First, it intensified rapidly. The storm began as an area of low pressure observed on Thursday by India's Meteorological Department (IMD), <a href="https://www.accuweather.com/en/hurricane/severe-cyclonic-storm-gati-bearing-down-on-somalia/852100" rel="noopener noreferrer" target="_blank">AccuWeather reported</a>. By Sunday, it had strengthened to a tropical depression; 12 hours later, it was a severe cyclonic storm. Lillo noted that its 12-hour intensification was the largest on record in the basin.</p><p>Gati intensified partly because of warm <a href="https://www.ecowatch.com/tag/ocean" target="_self">ocean</a> temperatures, according to AccuWeather. Other factors included low wind shear and the fact that it was relatively small, Lillo told NPR.</p><p>"With climate change we're seeing warmer ocean temperatures and a more moist atmosphere that's leading to a greater chance of rapid intensification for tropical cyclones like Gati," meteorologist and climate journalist Eric Holthaus told NPR. "Gati's strength is part of that broader global pattern of stronger storms."</p>

Key West voters have passed three ballot initiatives to limit the impact of visiting cruise ships on island life and fragile marine habitats. felixmizioznikov / iStock / Getty Images Plus
Despite being a well-known port of call on the Caribbean cruise circuit, the City of Key West voted to ban large cruise ships from visiting and to restrict foot traffic from vessels. Supporters and opponents disagreed about the safety, environmental and economic merits of the proposals.
<p>On election day, local voters passed three ballot initiatives to limit the impact of visiting cruise ships on island life and fragile marine habitats. According to the local <a href="https://www.keys-elections.org/Election-Data/Past-County-Results-2009-Current" target="_blank">Board of Elections</a>, 63% of residents voted to ban ships with capacities larger than 1,300 passengers from docking at all; 61% voted to limit the total daily number of passengers disembarking to 1,500; and 81% supported a measure that prioritizes cruise lines with the best environmental and health records to fill those 1,500 slots.</p><p>The referenda are effective immediately and binding but are expected to be challenged in court, reported <a href="https://thepointsguy.com/news/key-west-cruise-ship-ban/" target="_blank">The Points Guy</a> and <a href="https://www.usatoday.com/story/travel/cruises/2020/11/05/key-west-florida-voters-opt-ban-large-cruise-ships-visiting/6171877002/" rel="noopener noreferrer" target="_blank">USA TODAY</a>.</p>
<p>According to the <a href="https://www.safercleanerships.com/" target="_blank">Key West Committee for Safer, Cleaner Ships (SCS)</a>, who spearheaded the effort, a cruise line's environmental record will be determined by the number of environmental violations, penalties and fines accumulated. Health scores will be determined under the <a href="https://www.cdc.gov/nceh/vsp/default.htm" target="_blank">Center for Disease Control and Prevention's Vessel Sanitation Program</a>.</p><p>"For decades, the City of Key West has done nothing to regulate cruise ships, despite growing local frustrations with the threats large cruise ships pose to the environment, quality of life and sustainable economic growth," SCS treasurer and outspoken opponent of large ships Arlo Haskell explained to EcoWatch. "The fact that cruise ships now pose a clear risk to public health due to Covid-19 was, for us, the last straw."</p><p><a href="https://www.ecowatch.com/environmental-report-card-grades-cruise-ships-1881802453.html" target="_self">Cruise ships often damage the environment</a>. In addition to creating <a href="https://www.ecowatch.com/cruise-ships-toxic-water-sea-2640805829.html?share_id=4932404" target="_self">vast amounts of waste and carbon emissions</a>, they also degrade nearby habitats.</p>
<p><a href="https://floridakeys.surfrider.org/" rel="noopener noreferrer" target="_blank">Surfrider Florida Keys (SRFK)</a> supported the three initiatives to "give our coral reefs and marine environment a voice," said vice-chair Whitney Wemett. The local <a href="http://www.ecowatch.com/tag/coral-reefs">coral reefs</a> serve as vital nursery grounds, aggregation spots, habitat and food source for many marine species, she noted.</p><p>According to Haskell, the Key West port is narrow, shallow and long. It's also located right next to part of the only barrier coral reef in the country, the survival of which is dependent upon clean, clear water. Transiting cruise ships stir up silt from the seafloor and create "chronic turbidity" lethal to sea life. SRFK chair Shawn Martin hopes the exclusion of bigger ships will reduce not just the sediment plumes of silt over the reef but also pollution from human sewage, greywater and plastic waste.</p><p>"Limiting the type and size of cruise ships coming into port will lessen the stress on the ocean ecosystem and be a step in the right direction for improving water quality — a crucial element to healthy reefs," Martin told EcoWatch.</p>
<p>Local restaurant owner and opponent of the cruise ship prohibitions Bill Lay agreed on the need to protect the environment but asserted that the initiatives were the wrong way to do it.</p><p>"CSC used the cover of Covid-19 as a tool, a once-in-a-lifetime opportunity to get rid of ships," he said. "But, economically, you're taking a community devastated by the pandemic and just throwing salt on the wound. Our local businesses need foot traffic from the cruise ships."</p><p>While his two restaurants do not serve cruise passengers because they're only open for dinner, Lay predicted he and other business owners like him would feel the "domino effect" of the tightened regulations as locals whose businesses do rely on cruise traffic shutter.</p><p>The <a href="https://www.keywestchamber.org/" rel="noopener noreferrer" target="_blank">Key West Chamber of Commerce</a> similarly estimated that eliminating the cruise industry will cost the island $90 million in lost jobs and income, reported <a href="https://www.wlrn.org/2020-11-04/key-west-votes-to-limit-number-of-cruise-passengers-and-ship-size" rel="noopener noreferrer" target="_blank">WLRN</a>.</p>
<p>Haskell presented the economics differently, calling the idea that large cruise ships are essential to Key West's economy a "myth propagated by the cruise industry." While cruise ship passengers account for 50% of all visitors to Key West, they represent less than 8% of tourist spending, because most of their money is spent onboard the ship, he said.</p><p>"The meager economic benefit in Key West is simply not worth the profound risk posed by large cruise ships," he said.</p><p>"If these reefs die, so too do the industries that rely on them," Martin added. "If we do not put the health of our coral reefs first, there will be no Key West tourist economy."</p><p>"We can't afford to be shortsighted, and this move was one geared towards a strong and vibrant future for Key West," Wemett concluded.</p><p>The committee is eager to work with the cruise industry to bring qualifying small ships to Key West. Haskell asserted that a true solution would need to be about "balance" between environment and economy, with an eye on long-term economic sustainability without environmental degradation.</p>

In the South Atlantic Ocean, a tiny island of 250 people has made a significant contribution to global marine conservation by protecting a huge swath of ocean under its control.
<p>To reach Tristan da Cunha, a UK overseas territory, one must make a seven-day boat trip from South Africa, reported <a href="https://www.nationalgeographic.com/environment/2020/11/tristan-da-cunha-atlantic-marine-protection-zone/" rel="noopener noreferrer" target="_blank">National Geographic</a>. The island chain recently announced that 700,000 square kilometers (270,271 square miles), or 90% of its territorial waters, will be designated as a large marine protected area (MPA) to safeguard the area's rich <a href="http://www.ecowatch.com/tag/biodiversity">biodiversity</a> and <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered animals</a>, <a href="https://www.theguardian.com/environment/2020/nov/13/tiny-atlantic-island-takes-giant-leap-towards-protecting-worlds-oceans" rel="noopener noreferrer" target="_blank">The Guardian</a> reported. At that size, it will be three times the size of Britain, the largest marine sanctuary in the Atlantic and the fourth largest in the world, providing refuge to sevengill sharks, whales and seals, <a href="https://apnews.com/article/tristan-da-cunha-rockhopper-penguins-39c5e5d74120972e871327b04f823114" rel="noopener noreferrer" target="_blank">AP News</a> continued.</p>
<p>The new wildlife refuge will be a "no-take" zone, baning bottom-trawling fishing, deep-sea mining and other harmful and extractive harvesting from its waters, National Geographic reported. This will also protect the foraging grounds of tens of millions of seabirds that roost on the island, such as endangered Tristan and yellow-nosed albatross, Atlantic petrel and rockhopper penguins. Critically, these protections will bolster the small Tristan Rock Lobster commercial fishery outside the sanctuary, which is the territory's most important source of income, AP News reported. This luxury crayfish is sold to the U.S., Europe, Japan and China.</p><p>Experts believe that MPAs are a "silver bullet for conservation," <a href="https://earth.org/tristan-da-cunha-marine-protected-area/" target="_blank">Earth.org</a> noted. The <a href="https://www.weforum.org/agenda/2020/11/expanding-marine-protected-areas-mpa-sustainability-conservation/" rel="noopener noreferrer" target="_blank">World Economic Forum (WEF)</a> found that MPAs worldwide protect food supplies by leading to larger catch yields through "spillover," where fish from protected areas reproduce and enter fishing hotspots in greater abundance. Expanding the current network of protected areas by just 5% could boost global fish catch by at least 20%, the WEF asserted.</p>
<p>The protected area will join the UK's <a href="https://www.gov.uk/government/publications/the-blue-belt-programme" target="_blank">Blue Belt Programme</a>, which has funded 27 million pounds ($35.5 million) to promote marine conservation in UK overseas territories, AP News reported. The initiative has protected 11.1 million square kilometers (4.3 million square miles) of marine environment, or 1% of the world's oceans, Prime Minister Boris Johnson said, the report added.</p><p>The program continues to inch closer to the <a href="https://www.ecowatch.com/un-biodiversity-sixth-mass-extinction-2644807009.html?rebelltitem=1" target="_self">global target of protecting 30% of the world's oceans by 2030</a>. Scientists believe that this is the minimum required percentage of protected habitat to preserve <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> and safeguard ecosystems and their functions. According to National Geographic, roughly 8% of the world's oceans are currently designated as MPAs, but only 2.6% are totally off limits to fishing.</p><p>Johnson said, "We need collective global action if we are to bequeath a world that is every bit as wonderful and magnificent as the one we inherited," reported The Guardian.</p><p>According to Earth.org, the UK holds a duty to protect wildlife found in all its territories and will take charge of monitoring and enforcement within the new MPA. This is especially important because the nearest habitation, Saint Helena, is 2,400 km away. Through the Blue Belt Programme, Tristan da Cunha will receive more resources to patrol for illegal fishing activity. Earth.org reported.</p>
<p>The <a href="https://www.pewtrusts.org/en/projects/pew-bertarelli-ocean-legacy" target="_blank">Pew Bertarelli project</a>, which promotes the creation of marine reserves around the world, also committed to help the archipelago protect its waters with technology that uses real-time data to evaluate ocean conditions and human activity such as fishing, AP News reported. The project is a joint venture of the Pew Charitable Trusts and the Bertarelli Foundation.</p><p>"This small community is responsible for one of the biggest conservation achievements of 2020," Beccy Speight, chief executive of the Royal Society for the Protection of Birds (RSPB) told AP News. "This will protect one of the most pristine marine environments on the planet."</p><p>James Glass, the territory's chief islander, said in a statement, "Our life on Tristan da Cunha has always been based around our relationship with the sea, and that continues today. That's why we're fully protecting 90% of our waters, and we're proud that we can play a key role in preserving the health of the oceans," reported AP News.</p><p>While the British government lauded the effort and called on other governments to take similar action to meet the ambitious 30%, some critics were not impressed. They noted the hypocrisy of encouraging others to act when the UK allows bottom-trawling in all but two of its domestic offshore MPAs, in <a href="https://www.theguardian.com/environment/2020/oct/09/revealed-97-of-uk-offshore-marine-parks-subject-to-destructive-fishing" target="_blank">another Guardian</a> article.</p><p>Jonathan Hall, head of UK overseas territory unit at the RSPB, told Earth.org, "We should also be looking at protecting UK waters. The contrast is stark. We have this small community that is showing leadership in protecting their waters, but there have been lots of examples this year where more effective management of our existing protected areas is needed."</p>

Hurricane Iota, the 30th named storm and 13th hurricane of a record-breaking season, is now bearing down upon Central America less than two weeks after Hurricane Eta devastated the region.
<p>Iota was a Category 1 storm 10 a.m. Sunday, with winds of around 90 miles per hour, <a href="https://www.nytimes.com/2020/11/13/world/americas/tropical-storm-iota.html" target="_blank">The New York Times reported</a>. However, it strengthened rapidly overnight and is now a Category 4 storm with winds up to 155 miles per hour, according to a 7 a.m. EST update from the <a href="https://www.nhc.noaa.gov/text/refresh/MIATCPAT1+shtml/161143.shtml" target="_blank">National Hurricane Center (NHC)</a>.</p><p>"Iota could be a catastrophic category 5 hurricane when it approaches Central America tonight," the NHC warned.</p>

<p>Iota is expected to make landfall in northeastern Nicaragua or eastern Honduras Monday night. It threatens a storm surge of up to 12 to 18 feet above normal tide levels, as well as "catastrophic wind damage" as it moves onshore.

The U.S. Navy has secured permission for exercises in the Pacific Northwest that could harm endangered orcas and other marine mammals.
The new rule, published in the Federal Register Thursday, would allow the Navy to increase the number of Southern Resident killer whales it could "take"—or potentially harm—from two a year currently to 51 a year through 2027, The News Tribune reported.
<p>"This plan allows Navy war games to harm and harass marine mammals from the Pacific Northwest to Alaska. Critically endangered orcas and right <a href="https://www.ecowatch.com/tag/whales" target="_self">whales</a> would be assaulted by sonar and explosions," <a href="https://biologicaldiversity.org/" rel="noopener noreferrer" target="_blank">Center for Biological Diversity</a> (CBD) <a href="https://www.ecowatch.com/tag/oceans" target="_self">oceans</a> program director Miyoko Sakashita said in a <a href="https://biologicaldiversity.org/w/news/press-releases/navys-pacific-northwest-training-plan-harms-hundreds-of-endangered-whales-2020-11-12/" rel="noopener noreferrer" target="_blank">press release</a>. "We understand the need for military training, but the Navy can do much more to balance that with its legal obligation to minimize harm to vulnerable <a href="https://www.ecowatch.com/tag/marine-life" target="_self">marine life</a>." </p>
<p>The plight of Southern Resident killer whales, the orcas that roam the waters between Washington and British Columbia, have attracted increased attention and urgency in recent years, especially after one mother <a href="https://www.ecowatch.com/orca-mother-calf-mourning-2594507257.html" target="_self">carried her dead calf</a> for 17 days. That mother finally <a href="https://www.ecowatch.com/orca-dead-calf-new-birth-2647545791.html" target="_self">gave birth</a> to a healthy baby this summer, but there are still only 74 Southern Resident killer whales left, according to the <a href="https://www.whaleresearch.com/orca-population" target="_blank">Center for Whale Research</a>. They <a href="https://www.ecowatch.com/emergency-order--resident-orcas-2530527365.html" target="_self">have been harmed</a> by a steep decline in their Chinook salmon prey, pollution and noise and disturbances below the waves.</p><p>It is the last threat that could be increased by the Navy activities, which include firing torpedoes, using sonar, detonating bombs and using underwater drones, according to The News Tribune. Sonar and explosions can make it harder for whales and orcas to hear, and can interrupt their feeding, reproduction and migration, the CBD pointed out. Underwater noise can also kill up to 50 percent of zooplankton, the basis of the marine food web.</p><p>The Marine Mammal Protection Act requires that the Navy get permission for any activities that could harm marine mammals from the National Oceanic and Atmospheric Administration (NOAA)'s National Marine Fisheries Service (NMFS). The NMFS regulation governs the Navy's Northwest Training and Testing, which will take place off the Pacific Coast from Northern California to Alaska beginning Nov. 9 of this year and concluding in 2027.</p><p>In addition to orcas, the Navy's activities are expected to harm or bother more than 200 humpback whales, 300 minke whales and 10 blue whales every year, CBD reported. They could also harm 2,539 Cuvier's beaked whales every year, out of a population of just 3,274. NMFS did not even consider how the Navy's activities would impact North Pacific right whales, which have a population of only a couple dozen.</p><p>The proposal prompted concerns from Washington State officials over the threat posed to orcas, which rose from two to 51 animals bothered each year because the Navy realized the animals' population was more dense in the testing area than previous models had indicated, according to The News Tribune.</p><p>"The approval of such a high level of incidental take without requiring any additional mitigation measures represents gross neglect of the agency's management responsibilities under the Endangered Species Act and the Marine Mammal Protection Act to avoid or mitigate impacts to this highly endangered and iconic species," the Washington Department of Fish and Wildlife, the Department of Natural Resources, the Puget Sound Partnership, State Office of Recreation and Conservation, the Governor's Office of Salmon Recovery and Commissioner of Public Lands Hilary Franz wrote in a <a href="https://www.documentcloud.org/documents/7002861-NMFS-7-16-20.html" target="_blank">joint letter</a> to NMFS in July.</p><p>In the final rule, NMFS responded to concerns about the increased take by saying it had added new mitigation measures to the final rule, including introducing new mitigation measures during explosive mine countermeasures and neutralization testing, as well as mitigation measures aimed at certain areas of critical habitat. The Navy is only responsible for less than one percent of boat traffic in the Pacific Northwest, according to The News Tribune.</p>

Are We Really Past the Point of No Return on Climate? Scientists Respond To Controversial New Study
13 November
Climate

A controversial new climate study has found that, even if greenhouse gas emissions were halted tomorrow, it might not be enough to stop temperatures from continuing to rise.
<p>The study, published in <a href="https://www.nature.com/articles/s41598-020-75481-z" rel="noopener noreferrer" target="_blank">Scientific Reports Thursday</a>, was conducted by two researchers at the BI Norwegian Business School. They used the ESCIMO climate model to determine that, even if emissions ceased tomorrow, the <a href="https://www.ecowatch.com/tag/permafrost" target="_self">permafrost</a> would continue to thaw for hundreds of years.</p><p>"According to our models, humanity is beyond the point-of-no-return when it comes to halting the melting of permafrost using greenhouse gas cuts as the single tool," lead author and professor emeritus of climate strategy Jorgen Randers <a href="https://www.sciencealert.com/controversial-model-finds-global-warming-will-continue-even-if-we-stop-emissions-tomorrow" target="_blank">told AFP</a>. "If we want to stop this melting process we must do something in addition – for example, suck CO2 out of the atmosphere and store it underground, and make Earth's surface brighter."</p>
<p>However, other <a href="https://www.ecowatch.com/tag/scientists" target="_self">scientists</a> have pointed to the simplicity of the model Randers and his colleague Ulrich Goluke used and cautioned against misinterpreting their findings as a reason to give up on <a href="https://www.ecowatch.com/tag/climate-action" target="_self">climate action</a>.</p><p>"This paper clearly may be cited in support of a misleading message that it is now 'too late' to avoid catastrophic climate change, which would have the potential to cause unnecessary despair," University of Exeter climate scientist professor Richard Betts <a href="https://foreignaffairs.co.nz/2020/11/13/mil-osi-united-kingdom-expert-reaction-to-study-using-a-simulation-to-estimate-how-long-global-warming-might-continue-for-if-greenhouse-gas-emissions-are-reduced-to-zero/" target="_blank">said in response</a>. "However, the study is nowhere near strong enough to make such a frightening message credible."</p>
<p>So what exactly does the study say? The researchers used their model to see what would happen by 2500 if emissions stopped today and if they slowly declined to zero by 2100, as AFP explained. In the first scenario, temperatures would still rise to around 2.3 degrees Celsius above pre-industrial levels within the next 50 years, taper off, then rise again starting in 2150. By 2500, the world would be around three degrees Celsius warmer and sea levels would rise by around three meters (approximately 9.8 feet). In the second, temperature and sea level rise would end up in the same place, but the temperature increase would be much faster.</p>
<p>The reason for the persistent increase comes from three feedback loops, the model found.</p><ol><li>The melting of <a href="https://www.ecowatch.com/tag/sea-ice" target="_self">sea ice</a>, which means that the sun's heat is absorbed into the darker <a href="https://www.ecowatch.com/tag/ocean" target="_self">ocean</a> instead of reflected back by the bright ice.</li><li>The thawing of permafrost, which releases more greenhouse gases into the atmosphere.</li><li>Increased moisture in the atmosphere, which in turn raises temperatures.</li></ol><p>The only way to have prevented runaway climate change would have been to have stopped burning <a href="https://www.ecowatch.com/tag/fossil-fuels" target="_self">fossil fuels</a> between 1960 and 1970, the model found, as <a href="https://eu.usatoday.com/story/news/nation/2020/11/12/reducing-greenhouse-gas-emissions-stop-climate-change-study/3761882001/" target="_blank">USA TODAY reported</a>. In order to stop temperatures and sea levels from rising now, we would have to remove at least 33 gigatons of carbon dioxide from the atmosphere every year starting this one.</p>
<p>The study authors were the first to admit their findings were limited to one model.</p><p>"We encourage other model builders to explore our discovery in their (bigger) models, and report on their findings," they wrote.</p><p>However, Betts noted that their model was not the model used by the Intergovernmental Panel on Climate Change (IPCC) and did not realistically simulate how the climate works.</p><p>Penn State University meteorologist Michael Mann agreed. He told USA TODAY that it was not very complex and did not accurately reproduce atmospheric and ocean circulation systems.</p><p>"While such models can be useful for conceptual inferences, their predictions have to be taken with great skepticism. Far more realistic climate models that do resolve the large-scale dynamics of the ocean, atmosphere and carbon cycle, do NOT produce the dramatic changes these authors argue for based on their very simplified model," he said. "It must be taken not just with a grain of salt, but a whole salt-shaker worth of salt."</p><p>That said, even the models used by the IPCC show that we will need to draw down carbon dioxide from the atmosphere to reach the Paris agreement goal of limiting warming to 1.5 degrees Celsius above pre-industrial levels, even if we achieve zero emissions by 2050.</p><p>"What the study does draw attention to is that reducing global carbon emissions to zero by 2050 is just the start of our actions to deal with climate change," University College London climate professor Mark Maslin said in response.</p>

A new study finds ocean waters heated by climate change give them extra fuel for hurricanes. 12019 / Needpix
Hurricanes are staying stronger for longer after making landfall, causing greater and more widespread destruction, because ocean waters heated by climate change give them extra fuel, according to a study published Wednesday in Nature.
<p>Researchers looked at 71 hurricanes that made landfall since 1967. </p><p>In the 1960s, hurricanes lost 75% of their energy in the first day after making landfall, but recent hurricanes lost only about 50% of their energy in that same timeframe.</p><p>As climate change continues to heat the planet's oceans and make extreme hurricanes even stronger, their slowed "decay" as detailed in this study could have major implications for inland cities unaccustomed to hurricanes. </p><p>"It would not be surprising if category one — even category two — hurricanes start to become more common in a place like Atlanta," Pinaki Chakraborty, a senior author of the study, told the Verge.</p>
