The temperature of the Arctic matters to the entire world: it helps to keep the global climate fairly cool. Scientists now say that by 2035 there could be an end to Arctic sea ice.
Melt Ponds Crucial<p>"The prospect of loss of sea ice by 2035 should really be focusing all our minds on achieving a low-carbon world as soon as humanly feasible."</p><p><a href="http://www.reading.ac.uk/search/search-staff-details.aspx?id=10813" target="_blank">Dr. David Schroeder from the University of Reading</a>, UK, who co-led the implementation of the melt pond scheme in the climate model, says, "This shows just how important sea ice processes like melt ponds are in the Arctic, and why it is crucial that they are incorporated into climate models."</p><p>The extent of the areas <a href="https://nsidc.org/cryosphere/seaice/characteristics/formation.html" target="_blank">sea ice</a> covers varies between summer and winter. If more solar energy is absorbed at the surface, and temperatures rise further, a cycle of warming and melting occurs during summer months.</p><p>When the ice forms, the ocean water beneath becomes saltier and denser than the surrounding ocean. Saltier water sinks and moves along the ocean bottom towards the equator, while warm water from mid-depths to the surface travels from the equator towards the poles.</p><p>Scientists refer to this process as the ocean's global "conveyor-belt." Changes to the volume of sea ice can disrupt normal ocean circulation, with consequences for global climate. </p>

"We don't have a definition of life," says Kevin Peter Hand, one early California morning when we speak via video. "We don't actually know what life is."
Alien Oceans Here and There<p>Europa, Enceladus, and Triton are just three of over 200 moons in our solar system. But they are special moons. They seem to have live, liquid water environments below the surface — also known as subsurface oceans — under an icy shell.</p><p>"These are global liquid oceans covered with ice," says Hand. "And if we go to Europa or Enceladus, these worlds where hydrothermal vents could exist, but where no continents exist, and there's no atmosphere, and if we found life, that would almost certainly point to an origin of life in hydrothermal vents."</p><p>And that may then tell us more about life on Earth. </p><p>Hydrothermal vents are found at extreme depths of around 6,000 kilometers (3,728 miles) in vast trenches below the surface of Earth's own ocean.</p><p>Not so long ago, those trenches were believed to be too dark for any life to exist. But through oceanographic research and commercial prospectors trawling for rare minerals like manganese nodules, we now know that hydrothermal vents are teeming with microbial life. So, the same may be true on a distant moon.</p><p>"That's not to say we'd be able to cross off the potential for the origin of life in tide pools on ancient Earth, but if we found life in hydrothermal vents on these moons, we would at least have another data point," says Hand.</p>
Biology Beyond Earth<p>Biology — or organic life as we know it — is perhaps the final piece in a jigsaw puzzle for space scientists.</p><p>Thanks to Galileo, says Hand, we know that the laws of physics work beyond Earth. So, too, with the principles of chemistry and geology.</p><p>"But we don't know whether this phenomenon called life has happened a second, independent time from life here on Earth. And that's why the question of a second origin of life is so compelling," says Hand.</p>
The Europa Clipper<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="367f258c4634fbd67ad3ce7ef3a73b5f"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/GqTaDCt_F1Y?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Hand's focus for now is Jupiter's moon, Europa. One of his current projects is the <a href="https://www.jpl.nasa.gov/missions/europa-clipper/" target="_blank">Europa Clipper</a> mission, which will perform about 45 so-called "flybys" of the moon. </p><p>Its launch date has yet to be decided. But the plan is for the Europa Clipper to take hi-resolution images of the moon's surface on a scale of between 50 centimeters per pixel and tens of meters per pixel.</p><p>It will look for organics, like salt.</p><p>It will have an ice penetrating radar onboard, and spectrometers that could "taste" any plumes erupting out of Europa.</p><p>"It will fly through the plumes and capture some of that material so we can analyze it directly. That will be phenomenal, but it won't get us down to the surface," says Hand. So, they are working on another mission that would land on Europa, too.</p>
Trident for Triton<p>Meanwhile, NASA's <a href="https://www.nasa.gov/press-release/nasa-selects-four-possible-missions-to-study-the-secrets-of-the-solar-system" target="_blank">Discovery Program</a> has two further outer solar system moon missions under consideration. One of those missions is called Trident. And if it's selected to move forward, the mission will investigate Neptune's moon, Triton.</p><p>Trident would launch in 2026 for a 12-year journey to Triton. The last spacecraft to study Triton was Voyager 2, which launched in 1977. It got to within 40,000 km of Triton, whereas Trident would get as close as 500 km on two flybys.</p><p>"Voyager gave us pictures that let us see geysers and plumes on Triton and that was 30 years ago — 50 years before Trident," says Yohai Kaspi, a professor of atmospheric dynamics and planetary science at the Weizmann Institute in Israel. "But with today's technology and imaging, we can do much better."</p><p>Kaspi and his colleagues are contributing a special clock to the project, with which they hope to measure the density and temperature of Triton's atmosphere.</p><p>The clock is called an Ultra-Stable Oscillator (USO).</p><p>It's a basically quartz clock, like a quartz wristwatch, but it's kept it at a very stable temperature to protect it from all the temperature variations in space.</p><p>"You hold it in a little oven, literally a tiny oven, with a stable temperature of one milliKelvin," says Kaspi, "and that gives us an accurate time frequency."</p><p>The spacecraft will have a radio link to Earth for the purpose of Kaspi's experiment and for general use, such as navigation. It will be a constant signal.</p><p>But the speed at which that signal travels back to Earth will change as the spacecraft enters and moves through Triton's atmosphere. The atmosphere is almost a filter through which the signal will have to pass. Measuring and comparing the difference in time it takes the signal to travel to Earth will allow scientists to measure thickness of Triton's atmosphere and build a profile of the moon's atmospheric temperature.</p>
How Do Moon Oceans and Their Atmospheres Interact?<p>Kaspi says Triton's atmosphere makes it unique. "Enceladus is too small to have an atmosphere and Europa barely has an atmosphere," he says. "Triton's atmosphere is not as dense as the one on Earth but it's enough of an atmosphere to transport material around. And in addition to that, it's likely that Triton was not even formed in our solar system. So, it's a real opportunity."</p><p>If the mission goes ahead, it may also be an opportunity to understand more about the interaction between subsurface oceans, or the "interior" of such moons, and their atmospheres. Because atmospheres are just as important for maintaining life and water is for originating life.</p><p>"We see these plumes coming from the interior, and they are then transported by the atmosphere. We see these active geysers and then these streaks on the planet, and they're all in the same direction," Kaspi says. "So, you would assume that there is a wind going from one side to the other. Voyager observed that. But that is about as much as we know."</p><p>What we don't know, says Kaspi, is how much of Triton's atmosphere originated from the interior, or whether the subterranean ocean can communicate or interact much with the outside.</p><p>The instruments on Trident are designed to find out how the whole system works together. They may even get us a little closer to that elusive definition of life itself.</p><p>"I hope that maybe 400 years from now our descendants will be able to point to innovations and discoveries that we made and go, 'Wow, can you believe they argued about the importance of searching for life beyond Earth and its application?'" says NASA's Kevin Hand.</p><p>"And perhaps they will be able to laugh about that in the same way that we look at Galileo and say: 'Of course, Galileo's work was pivotal in changing the way we think about the universe' — and everything that cascades from that, right down to the computer conversation that we're having now."</p><p>Message received.</p>

Sharks elicit outsized fear, even though the risk of a shark bite is infinitesimally small. As a marine biologist and director of the Florida Program for Shark Research, I oversee the International Shark Attack File – a global record of reported shark bites that has been maintained continuously since 1958.
A Big, Diverse Family<p>Not all sharks are the same. Only a dozen or so of the roughly 520 shark species pose any risk to people. Even the three species that account for almost all shark bite fatalities – the <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/carcharodon-carcharias/" target="_blank">white shark</a> (<em>Carcharodon carcharias</em>), <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/galeocerdo-cuvier/" target="_blank">tiger shark</a> (<em>Galeocerdo cuvier</em>) and <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/carcharhinus-leucas/" target="_blank">bull shark</a> (<em>Carcharhinus leucas</em>) – are behaviorally and evolutionarily very different from one another.</p><p>The tiger shark and bull shark are genetically as different from each other as a dog is from a rabbit. And both of these species are about as different from a white shark as a dog is from a kangaroo. The evolutionary lineages leading to the two groups split 170 million years ago, during the age of dinosaurs and before the origin of birds, and <a href="https://www.ck12.org/book/CK-12-Human-Biology/section/7.2/" target="_blank">110 million years before the origin of primates</a>.</p>
White, tiger and bull sharks are distinct species that diverged genetically tens of millions of years ago. Gavin Naylor / CC BY-ND<p>Yet many people assume all sharks are alike and equally likely to bite humans. Consider the term "shark attack," which is scientifically equivalent to "mammal attack." Nobody would equate dog bites with hamster bites, but this is exactly what we do when it comes to sharks.</p><p>So, when a reporter calls me about a fatality caused by a white shark off Cape Cod and asks my advice for beachgoers in North Carolina, it's essentially like asking, "A man was killed by a dog on Cape Cod. What precautions should people take when dealing with kangaroos in North Carolina?"</p>
Know Your Species<p>Understanding local species' behavior and life habits is one of the best ways to stay safe. For example, almost all shark bites that occur off Cape Cod are by white sharks, which are a large, primarily cold-water species that spend most of their time in isolation feeding on fishes. But they also aggregate near seal colonies that provide a reliable food source at certain times of the year.</p><p>Shark bites in the Carolinas are by warm-water species like bull sharks, tiger sharks and <a href="https://www.floridamuseum.ufl.edu/discover-fish/species-profiles/carcharhinus-limbatus/" target="_blank">blacktips</a> (<em>Carcharhinus limbatus</em>). Each species is associated with particular habitats and dietary preferences.</p><p>Blacktips, which we suspect are responsible for most relatively minor bites on humans in the southeastern United States, feed on schooling bait fishes like menhaden. In contrast, bull sharks are equally at home in fresh water and salt water, and are often found near estuaries. Their bites are more severe than those of blacktips, as they are larger, more powerful, bolder and more tenacious. Several fatalities have been ascribed to bull sharks.</p><p>Tiger sharks are also large, and are responsible for a significant fraction of fatalities, particularly off the coast of volcanic islands like Hawaii and Reunion. They are tropical animals that often venture into shallow water frequented by swimmers and surfers.</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="1cfa1c9590e386ecc9455b4762b87518"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/yDqzGOa-adc?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
Humans Are Not Targets<p>Sharks do not "hunt" humans. Data from the International Shark Attack File compiled over the past 60 years show a tight association between shark bites and the number of people in the water. In other words, shark bites are a simple function of the probability of encountering a shark.</p><p>This underscores the fact that shark bites are almost always cases of mistaken identity. If sharks actively hunted people, there would be many more bites, since humans make very easy targets when they swim in sharks' natural habitats.</p><p>Local conditions can also affect the risk of an attack. Encounters are more likely when sharks venture closer to shore, into areas where people are swimming. They may do this because they are following bait fishes or seals upon which they prey.</p><p>This means we can use environmental variables such as temperature, tide or weather conditions to better predict movement of bait fish toward the shoreline, which in turn will predict the presence of sharks. Over the next few years, the Florida Program for Shark Research will work with colleagues at other universities to monitor onshore and offshore movements of tagged sharks and their association with environmental variables so that we can improve our understanding of what conditions bring sharks close to shore.</p>
More to Know<p>There still is much to learn about sharks, especially the 500 or so species that have never been implicated in a bite on humans. One example is the tiny <a href="https://www.newsweek.com/one-worlds-rarest-sharks-also-one-most-adorable-325280" target="_blank">deep sea pocket shark</a>, which has a strange pouch behind its pectoral fins.</p><p>Only two specimens of this type of shark have ever been caught – one off the coast of Chile 30 years ago, and another more recently in the Gulf of Mexico. We're not sure about the function of the pouch, but suspect it stores luminous fluid that is released to distract would-be predators – much as its close relative, the <a href="https://sharkdevocean.wordpress.com/2015/04/23/second-ever-pocket-shark-discovered-in-gulf-of-mexico/" target="_blank">tail light shark</a>, releases luminous fluid from a gland on its underside near its vent.</p>

Although whale sharks are the largest fishes in the world, we have yet to locate their nursery grounds, which are likely teeming with thousands of <a href="https://www.earthtouchnews.com/oceans/sharks/baby-whale-shark-rescued-from-gillnet-in-india-video/" target="_blank">foot-long pups</a>. Some deepwater sharks are primarily known from submersibles, such as the giant <a href="https://twitter.com/gavinnaylor/status/1146144452681113601" target="_blank">sixgill shark</a>, which feeds mainly on carrion but probably also preys on other animals in the deep sea.</p><p>Sharks seem familiar to almost all of us, but we know precious little about them. Our current understanding of their biology barely scratches the surface. The little we do know suggests they are profoundly different from other vertebrate animals. They've had 400 million years of independent evolution to adapt to their environments, and it's reasonable to expect they may be hiding more than a few tricks up their gills.</p>

Melting and crumbling glaciers are largely responsible for rising sea levels, so learning more about how glaciers shrink is vital to those who hope to save coastal cities and preserve wildlife.
Groans, Creaks, Icebergs’ Calving Splashes<p>Oskar Glowacki already knew that melting glacial ice sounds like frying bacon. As ice bubbles burst, anyone nearby can hear crackling and popping, said Glowacki, a postdoctoral scholar at the Scripps Institution of Oceanography. Using hydrophones, he and other scientists now can make more nuanced measurements of how a changing climate sounds underwater, from the groans, creaks and splashes of a calving iceberg to the changes in whale songs as the ocean warms.</p><p>Glowacki recently used a pair of hydrophones to study the underwater world of glaciers, publishing his findings in <a href="https://www.the-cryosphere.net/14/1025/2020/" target="_blank">The Cryosphere</a>. He and co-author Grant B. Deane measured glacier retreat by <a href="https://yaleclimateconnections.org/2020/07/melting-glaciers-sound-like-frying-bacon/" target="_blank">recording the sounds of ice</a> – from small chunks to enormous slabs – falling off the glacier and splashing into the water.</p><p>During the summer of 2016, Glowacki's team placed two hydrophones near Hansbreen Glacier in Hornsund Fjord, Svalbard. For a month and a half, they recorded sounds, also using three time-lapse cameras to collect images – including the "drop height" (how far the ice fell into the water) – so they could compare photos to the recordings. The team created a formula to represent the relationship between the size of a piece of ice falling from a glacier and the sound it makes underwater, also accounting for the pieces of ice falling from varying heights. (Hear an example of the sound an iceberg makes while calving <a href="https://soundcloud.com/user-248456662/iceberg-calving-hansbreen-glacier" target="_blank">here</a>.)</p>
Unlocking Information About Antarctic Ice Shelf<p>Other researchers also are using hydrophones to learn more about crumbling glaciers. Bob Dziak, research oceanographer with the NOAA/Pacific Marine Environmental Laboratory <a href="https://www.pmel.noaa.gov/acoustics" target="_blank">acoustics research group</a>, captured a massive calving event of the Nansen Ice Shelf in Antarctica with a hydrophone. He published the results with colleagues in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00183/full" target="_blank">Frontiers in Earth Science</a></p><p>On April 7, 2016, satellite images showed a massive calving event had occurred on the ice shelf. The paper described it as the "first large scale calving event in >30 years."</p><p>However, once Dziak and colleagues delved into the data from three hydrophones deployed 60 kilometers east of the ice shelf, they uncovered a series of "icequakes" from January to early March 2016. He and other researchers believe that much of the ice actually broke free in mid-January to February, but it remained in the same location until an April storm – which their paper described as the "largest low-pressure storm recorded in the previous seven months" – broke the ice free.</p><p>"We suspected that the icebergs broke apart but remained in place – kind of pinned in place – until a major storm with high winds passed through the area and, finally, it was that last push that pushed the icebergs out to sea," Dziak says.</p><p>He and his co-authors wrote that "fortuitous timing and proximity of the hydrophone deployment presented a rare opportunity to study cryogenic signals and ocean ambient sounds of a large-scale ice shelf calving and iceberg formation event."</p>
Listening to Songs of Humpback Whales<p><a href="https://www.mbari.org/" target="_blank">Monterey Bay Aquarium Research Institute</a> studies the ocean, including its acoustics. One of the institute's projects involves examining the soundscape of California's Monterey Bay, including sounds from animals, humans, weather, and geologic processes like earthquakes. The researchers once even recorded an under-sea landslide. They also focus on recording and analyzing the <a href="http://www.mbari.org/humpback-song/" target="_blank">songs of humpback whales</a>. Male humpback whales' songs can be over 15 minutes in length, and they can be repeated for long periods of time – even hours. Listening to these songs and analyzing them can provide unique insights into the lives of these complex animals.</p><p>"Any time we want to study marine mammals, sound gives us a window into their lives because they use sound for all of their essential life activities, really," says institute biological oceanographer John Ryan. "Communication, foraging, reproduction, navigation – depending on the species, of course."</p><p>Previously, scientists had thought singing occurred only during courtship and mating, but now they think whales may also use song while migrating and hunting. They know song has a crucial role in the whales' lives.</p><p>"There's a whole other dimension to humpback whale song," Ryan says. "It is a mode of cultural transmission in this species. They learn songs from each other. They share songs as a population, and when populations mix and mingle, they learn new ideas, they explore with their song, improvise, and it's a real essential part of their culture."</p>

A number of conservationists claim cats are a zombie apocalypse for biodiversity that need to be removed from the outdoors by "any means necessary" – coded language for shooting, trapping and poisoning. Various media outlets have portrayed cats as murderous superpredators. Australia has even declared an official "war" against cats.
Faulty Scientific Reasoning<p>In our <a href="https://doi.org/10.1111/cobi.13527" target="_blank">most recent publication</a> in the journal Conservation Biology, we examine an error of reasoning that props up the moral panic over cats.</p><p>Scientists do not simply collect data and analyze the results. They also establish a logical argument to explain what they observe. Thus, the reasoning behind a factual claim is equally important to the observations used to make that claim. And it is this reasoning about cats where claims about their threat to global biodiversity founder. In our analysis, we found it happens because many scientists take specific, local studies and overgeneralize those findings to the world at large.</p><p>Even when specific studies are good overall, projecting the combined "results" onto the world at large can cause unscientific overgeneralizations, particularly when <a href="https://doi.org/10.1016/j.tree.2015.01.003" target="_blank">ecological context is ignored</a>. It is akin to pulling a quote out of context and then assuming you understand its meaning.</p>
Ways Forward<p>So how might citizens and scientists chart a way forward to a more nuanced understanding of cat ecology and conservation?</p><p>First, those examining this issue on all sides can acknowledge that both the well-being of cats and the survival of threatened species are legitimate concerns.</p><p>Second, cats, like any other predator, affect their ecological communities. Whether that impact is good or bad is a complex value judgment, not a scientific fact.</p><p>Third, there is a need for a more rigorous approach to the study of cats. Such an approach must be mindful of the importance of ecological context and avoid the pitfalls of faulty reasoning. It also means resisting <a href="https://doi.org/10.1111/cobi.13126" target="_blank">the siren call of a silver (lethal) bullet</a>.</p>

The immediate emergency of COVID-19 has been a powerful reminder that the most valuable things in our lives are our families, friends, and the welfare of our communities.
Thousands of People in the SJV Live Without Reliable Access to Water.<p>California is the wealthiest state in the most prosperous country in the world, and yet, there are close to one million people living without reliable access to safe, clean, and affordable drinking water. Most of these people are <a href="https://www.nytimes.com/2019/05/21/us/california-central-valley-tainted-water.html" target="_blank">concentrated in disadvantaged communities</a> in the SJV. California identifies <a href="https://oehha.ca.gov/calenviroscreen/sb535" target="_blank">disadvantaged communities</a> as areas that experience disproportionate levels of a combination of poverty, air and water pollution, high unemployment, and high rates of cardiovascular diseases and asthma. According to a report from the UC Davis Center for Regional Change, residents in these communities are <a href="https://regionalchange.ucdavis.edu/publication/water-justice" target="_blank">over 60% Hispanic</a>.</p><p><span></span>The SJV is one of the most productive agricultural regions in the world, <a href="https://www.ppic.org/wp-content/uploads/water-and-the-future-of-the-san-joaquin-valley-overview.pdf" target="_blank">producing more than half of California's agricultural output</a> with over 200 different crops and annual revenue of about 20 billion US dollars. The astonishing volume of water that agriculture requires has led to over-exploitation of groundwater and the continuous lowering of groundwater levels that has impacted water quality and quantity.</p><p>Groundwater is the primary source for household water needs and agricultural water supply. Yet, thousands of people are unable to drink and use the water in the SJV, because there are multiple contaminants in it. Some of the water pollution comes from natural sources and includes substances like arsenic, but most of it has emerged due to agricultural practices. These contaminants include pesticides and nitrates, which are linked to cancer, birth defects, and blue baby syndrome.</p><p>In years with average precipitation, water flowing in California's rivers from rain and melted snowpack meets about 60 percent of the state's water demand and groundwater meets the remainder. However, during dry years water supply sources shift and put severe stress on groundwater levels. During the California drought from 2012 to 2016, groundwater use, mostly from agricultural water pumping, <a href="https://www.sciencemag.org/news/2020/04/droughts-exposed-california-s-thirst-groundwater-now-state-hopes-refill-its-aquifers" target="_blank">grew to 80 percent</a> in some regions of the SJV increasing overdraft. Groundwater overdraft occurs when water extractions exceed recharge into an aquifer. An analogy is your bank account; extract more money than is put in, and your account will go dry. Aquifers are like a shared account, with some people taking out more than others. Consequently, thousands of domestic wells ran dry, unable to reach water due to lowered groundwater levels, in large part due to increased agricultural water pumping, and affecting thousands of people across the valley.</p><p>We think about drought as standalone events, but in reality, human actions triggered by droughts can have effects that continue long after the drought has ended, like permanently lowering the water table. In the SJV, the last drought has permanently reduced the capacity of some aquifers because overdraft left air in between soil particles instead of water, and the soils subsided eliminating the space for water storage. Overdraft also leads to infrastructure damage from land subsidence, that is when the ground levels drop, plus reduction of surface water, and an increase in water quality problems. That range of concerns brought by overdraft formed the basis of SGMA.</p>
Groundwater Sustainability Plans Could Fix Part of the Problem but Are Currently Inadequate.<p>SGMA passed in 2014 and is the first legislation in California to mandate sustainable management of groundwater resources. SGMA is intended to bring about groundwater sustainability by the year 2040. Local water agencies describe the means to achieve this goal in their Groundwater Sustainability Plans (GSPs). For those interested in the details of SGMA, <a href="https://water.ca.gov/Programs/Groundwater-Management/SGMA-Groundwater-Management" target="_blank">here is a thorough description of it</a>. The focus of this post is on the latest developments.</p><p>The 21 most critically over-drafted groundwater basins submitted their GSPs at the beginning of the year and are now under review by the California Department of Water Resources (DWR). External reviews of these plans argue that some of them do not sufficiently address current and future impacts on disadvantaged communities. For example, the Groundwater Leadership Forum (a group of organizations funded by the <a href="https://waterfdn.org/" target="_blank">Water Foundation</a> focused on ensuring the success of SGMA and of which UCS is part) also reviewed several GPSs and found gaps in how drinking water, climate change, stakeholder involvement, managed wetlands, and groundwater-dependent ecosystems were addressed in the plans. The Public Policy Institute of California (PPIC) reviewed 36 plans submitted for basins overlapping the SJV. They found Kings Basin (surrounding Fresno) stands out for having the highest number of domestic wells that may go dry, about 600 of them, under the proposed water level sustainable thresholds and yet the local groundwater plan considers that an <a href="https://www.ppic.org/blog/will-groundwater-sustainability-plans-end-the-problem-of-dry-drinking-water-wells/" target="_blank">insignificant impact from continued overdraft</a>. This is concerning and unacceptable. Public comments can be consulted in the <a href="https://sgma.water.ca.gov/portal/gsp/all" target="_blank">SGMA portal from DWR</a>.</p><p>I, and many others are concerned that multiple GSPs have questionable integrations of climate change projections. GSPs are considering numerous projects to tackle their local overdraft, yet they are not planning for the uncertain future that climate change is bringing. To reduce some of the vulnerabilities that we see now, GSPs need to integrate climate change and show benefits on the range of future scenarios.</p><p>Another concern is that on May 14, the <a href="http://www.ebudget.ca.gov/FullBudgetSummary.pdf" target="_blank">Governor announced</a> a $40 million cut on funding for SGMA. Part of the money was expected to support 37 new staff positions at DWR to uphold its statutory obligation on reviewing GSPs. While the budget still allocated $26 million of existing Proposition 68 bond funds to help with implementation projects in critically overdraft basin, it is unlikely that DWR will have the capacity to review the GSPs thoroughly. However, the governor's budget did prioritize safe and affordable drinking water and the State Water Board approved <a href="http://californiawaternewsdaily.com/infrastructure/state-water-board-approves-2020-21-funds-to-improve-access-to-healthy-drinking-water/" target="_blank">$130 million for 2020-2021</a> to projects that support such objective on vulnerable communities.</p>
Without Bold Action and Preparation, Climate Change Threats May Bring Similar Impacts to Those of COVID-19.<p>The lack of drinking water causes many residents in the valley to rely on bottled water as their primary source for drinking and cooking. Panic buying at the beginning of the pandemic left stores across the valley without bottled water. In the case of COVID-19, unsafe and unreliable access to water has endangered a multitude of low-income communities by preventing them from performing protective, hygienic acts, handwashing, in particular, and forcing them to go to public water supply kiosks. As we've all learned, hand washing is one of the most necessary measures needed to slow and stop the spread of a virus. Without a correct implementation of groundwater sustainability plans under SGMA, many of these risks will continue.</p><p>Shelter in place orders resulted in people losing their jobs and hence, their source of income and being unable to pay utility services. Small utility services were also impacted because of low economic margins of operations in which small drops in income translate to being unable to provide service. Fortunately, many organizations and individuals wrote a letter to Governor Newsom that prompted him to issue an <a href="https://www.gov.ca.gov/2020/04/02/governor-newsom-issues-executive-order-protecting-homes-small-businesses-from-water-shutoffs/" target="_blank">executive order</a> protecting homes and small businesses from water shutoffs.</p><p>We now have the opportunity to give meaning to these current hardships by learning from them to prevent hardships from climate change. Climate change is a threat intensifier. In this case, the threat is a virus, and historical inequities and water vulnerabilities increased its impact on the most vulnerable among us. An example of the unpreparedness of the system to support our vulnerabilities during times of crisis is seen in the case of school children who rely on school lunches as their main meal of the day but are now unable to access this resource due to school closures. Some farmworkers, <a href="https://www.nytimes.com/2020/04/02/us/coronavirus-undocumented-immigrant-farmworkers-agriculture.html" target="_blank">while cataloged as 'essential' by the federal government</a> during this crisis, are undocumented and were not part of the stimulus package. The height of irony is <a href="https://www.kvpr.org/post/covid-19-deepens-food-insecurity-san-joaquin-valley" target="_blank">farmworkers struggled with access to food distribution</a> when they needed it.</p>
There Is No Scenario Where Water Is Not Absolutely Necessary to Lessen the Impacts During a Crisis.<p>One of my <a href="https://blog.ucsusa.org/cecilia-moura/covid-19-air-pollution-and-health-impacts-an-interview-with-pediatric-pulmonologist-dr-denise-serebrisky" target="_blank">colleagues wrote</a> that moments of crisis often expose the weak points of a system. In the SJV, the weak points of the water system have been exposed for years and won't be strengthened without managing water resources sustainably. This is evidenced by the number of people in the SJV without access to safe, clean, and affordable drinking water. Considering that about <a href="https://www.theguardian.com/environment/2020/feb/28/california-water-wells-dry-sgma" target="_blank">95% of valley residents</a> depend on groundwater for at least part of their water, it is critical that GSPs explicitly include strategies for addressing some of the current and future water issues in the SJV.</p><p>Numerous, various kinds of climate threats will come, whether they develop as <a href="https://www.nature.com/articles/s41558-020-0804-2" target="_blank">floods, heatwaves, wildfires, droughts, or other climate hazards</a>, we need to be prepared and do everything possible to improve sustainable water management for all. While future climate-change-derived crises most likely will be different than COVID-19, there is no scenario where water is not absolutely necessary to lessen the impacts.</p>
