As we reach the official end of hurricane season, 2020 will be one for the record books. Looking back at these long, surprising, sometimes downright crazy past six months (seven if you count when the first named storms actually started forming), there are many noteworthy statistics and patterns that drive home the significance of this hurricane season, and the ways climate change may have contributed to it.

A blue whale can weigh as much as 200 tons and consume 12,000 pounds of krill in a single day. But even the largest animal on Earth doesn't stand a chance against a fast-moving cargo ship.
1. Acoustic monitoring instruments identify whale vocalizations. 2. Observers record whale sightings with a mobile app. 3. Oceanographic data is used to predict where blue whales are likely to be. 4. The data streams are compiled and validated. 5. Whale information is disseminated to industry, managers and the public. Nicolle R. Fuller, Sayo Studio<p><span style="background-color: initial;">There are three main components.</span><br></p><p>One is an acoustic listening station. Out in the Santa Barbara channel, our collaborators at Woods Hole Oceanographic Institution and Texas A&M University at Galveston deployed an acoustic buoy that has an underwater microphone near the seafloor. There's a small computer that processes any audio that the microphone picks up.</p><p>It is able to automatically detect the calls of blue, humpback and fin whales. Then there's a surface buoy with a satellite transmitter that sends that information back to shore. It's then validated by a scientist on shore before it's added to the database.</p><p>Then the second piece is a blue whale habitat model. We use oceanographic data like sea-surface temperature and current to predict where blue whales are likely to be on any given day. That was developed by our collaborators at U.C. Santa Cruz, the University of Washington and NOAA Southwest Fishery Science Center.</p><p>It's a dynamic model that's running every day in an automated fashion and producing maps that show us blue whale hotspots.</p><p>The third piece is data gathered by community scientists who are out on whale-watching and tourism boats nearly every day. They use mobile apps such as <a href="http://www.whalealert.org/" target="_blank">WhaleAlert</a> and <a href="http://whaleaware.org/index.php?page=download-spotter" target="_blank">Spotter Pro</a> to record whale sightings that are also added to the database.</p>
Deploying the acoustic detection system in the Santa Barbara Channel near the shipping lanes in 2019. Benioff Ocean Initiative<p>There are quite a few challenges, both on the technological side and just the bureaucratic side, of actually getting the data delivered that way. It's their main safety and navigation tool, so you don't want it to be crowded with too much data and information. That would need to be done really thoughtfully. But that's a communication pathway that could really help get this data more easily adopted.</p><p><strong></strong><strong>Right now there are voluntary slow-speed zones, but some ships aren't abiding by those recommendations. How likely do you think they'd be to adopt technology like Whale Safe?</strong></p><p>A few years ago there was actually a NOAA-led working group that brought together many stakeholders to try to develop solutions. One of the recommendations that came out of that process was actually a call for new technology and more real-time data on whale activity. And that was supported by many members of the shipping industry that were part of that working group.</p><p>That helped to inform the approach that we decided to take. Some of these companies expressed that time is money, and if they're going to slow down, they want to make sure that they're slowing down because there are actually whales in the area.</p><p>Our hope is that this data can really help to reinforce those slow-speed zones, especially when there's high whale activity in the channel.</p>
The last decade was the hottest since record-keeping began 150 years ago, according to the latest data from U.S. agencies the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA).

At this time of year, in Russia's far north Laptev Sea, the sun hovers near the horizon during the day, generating little warmth, as the region heads towards months of polar night. By late September or early October, the sea's shallow waters should be a vast, frozen expanse.

Arctic sea ice extent on Oct. 25, 2020 was at a record low 5.613 million square kilometers for this date, surpassing the record set in 2019 of 6.174 million square kilometers. ChArctic NSIDC
The Arctic appears to be changing into an entirely new climate state due to rapid warming. The extent of sea ice in the late summer, when it reaches its minimum each year, has already entered a statistically different climate, with surface air temperatures and the number of days with rain instead of snow also beginning to transition.

Hundreds of endangered sea turtles were stranded on beaches after suffering "cold stunning" in the waters off Cape Cod, Mass. Local rescuers and wildlife rehabilitators stabilized the turtles at the New England Aquarium (NEAQ) and National Marine Life Center and began treatment. Many of the sea turtles were transported by land or air to partner facilities around the Eastern Seaboard for longer-term care to make room for more incoming, cold-stunned animals.
Rehabilitators at The Turtle Hospital in the Florida Keys assess critically endangered, cold-stunned Kemp's ridley sea turtles flown in after rescue in New England. The Turtle Hospital<p>NEAQ and local rescuers begin seeing turtles every fall when water temperatures drop to that 50 degrees F threshold, and typically expect to find them into early January. After that, <a href="https://www.ecowatch.com/sea-turtle-cape-cod-weather-2621527394.html" target="_self">temperatures are so cold that any animals found are usually no longer alive</a>.</p><p>Merigo estimated that this year's cold season "looks very busy" and noted that local rescue efforts had already surpassed 400 turtles.</p><p>"It is a lot of animals. They're still coming in," she told EcoWatch as she surveyed 39 rescued turtles that day and 20 the day prior. "So far, this is a huge year."</p><p>At NEAQ, the turtles are gradually warmed up about five to 10 degrees F a day. More aggressive warming can cause serious damage and the turtle might not survive, Merigo said. Emergency treatments also include providing replacement fluids, balancing electrolytes and addressing pneumonia. Assessments take place for other serious problems too, such as shell or limb fractures, frostbite, emaciation and eye damage.<span></span></p><p>As local aquariums don't have the capacity to care for all the injured turtles, a group of private pilots called <a href="https://www.turtlesflytoo.org/" target="_blank">"Turtles Fly Too"</a> donated planes, fuel and time to transport some to various partner facilities around the country. Other turtles were driven to closer care facilities.</p><p>"We have a huge network of really great partners working with us, so if we can spread out the care, we can give better care to all the animals," Merigo said.</p><p>The 40 Kemp's ridley sea turtles recovering in The Turtle Hospital will continue to be treated and rehabilitated anywhere from 30 days to a year, depending on the severity of injuries, Zirkelbach said.</p><p>The turtle expert noted that while she's treated cold-stunned turtles from the north before, the newest arrivals were the most cold-stunned Kemp's ridleys ever received at one time.</p>
After rescue, cold-stunned sea turtles received immediate emergency care and assessments at the New England Aquarium. Caitlin Cunningham / New England Aquarium<p>In the past decade, the Gulf of Maine, which spans from Cape Cod to Nova Scotia, has warmed 99 percent faster than the rest of the ocean, Zirkelbach said. The warm water encourages turtles that migrate north along the Gulf Stream in warmer months to stay in the bay longer.</p><p>"Turtles that fail to migrate south get stuck in the unique horseshoe-shaped topography of the Cape Cod peninsula, and when temperatures drop, the bay becomes a death trap," she added.</p><p>Before ocean temperatures warmed, the waters of Maine were too cold for many of these sea turtles, Merigo echoed. Now, with warming sea surface temperatures, Maine can reach the high 70s to low 80s, which is "perfect turtle temperature," she said. The potential for more turtles getting trapped in the bay and then cold-stunned is nerve-racking for Merigo.</p><p>In addition to shifting habitats as waters warm, warming global temperatures also disrupt natural gender balance in sea turtles, Merigo warned. Gender is determined by the temperature of eggs in nests, and as the planet warms, it will result in all females at some point, she said.</p><p>"The turtles we work with are all endangered and threatened," Merigo said. "For sea turtles in general, the future is a little grim. Climate change is real; it does impact them."</p>

When storms like Huricane Zeta menace the Gulf Coast, residents know the drill: Board up windows, clear storm drains, gas up the car and stock up on water, batteries and canned goods.
But how does wildlife ride out a hurricane? Animals that live along coastlines have evolved to deal with a world where conditions can change radically. This year, however, the places they inhabit have borne the brunt of 10 named storms, some just a few weeks apart.
