House Passes First Major Climate Bill in 10 Years
The U.S. House of Representatives approved its first major climate change legislation in a decade on Thursday, Reuters reported. The Climate Action Now Act would require President Donald Trump to keep the U.S. in the Paris agreement, mandating that he outlines steps to reduce greenhouse emissions and prohibiting him from using federal funds to withdraw from the agreement.
The bill passed 231 to 190, with three Republicans crossing the aisle to approve it with the Democrats. It is unlikely to pass the Senate, but the Democrats see it as a way to stake out a climate position ahead of the 2020 election and to signal to the international community that a future Democratic president would stay in the agreement, The Washington Post reported.
"Passing this bill is an important signal to our allies, and my expectation is that when we act, we'll see increased ambition from them, too," Democratic Florida Representative Kathy Castor, who sponsored the legislation and chairs the House Select Committee on the Climate Crisis, told the press before the vote, as The Washington Post reported.

While Trump promised to withdraw from the Paris accord in June 2017, he cannot legally do so until November 2020.
"That's an interesting date, isn't it?" Castor said.
Senate Majority Leader Mitch McConnell said the bill would "go nowhere" in the Senate and called it a "futile gesture to handcuff the U.S. economy," The New York Times reported.
In debating the measure, House Republicans focused on the Paris agreement's impact on the U.S. economy and either avoided discussions of the science of climate change itself or acknowledged it as an issue worth confronting. Instead of denying science, they argued that other countries in the agreement, particularly China and India, had not pledged enough.
The Obama administration had promised to reduce greenhouse gas emissions to 28 percent of 2005 levels by 2025; China promised to slow its emissions growth and reach peak carbon in 2030, and India said it would reduce the carbon dioxide emitted per unit of gross domestic product while still allowing overall emissions to rise.
In the debate ahead of the vote, Texas Republican Representative Jodey Arrington called the deal "a gift to our enemies" and Louisiana Republican Steve Scalise said it would send jobs to China and India. However, not all Republicans portrayed climate action as a threat to the U.S. economy.
"Environmental protection and economic growth are not mutually exclusive," Florida Republican Representative Vern Buchanan, one of three Republicans who voted for the act, said, as The Washington Post reported.
Moments ago I voted for legislation to keep the United States part of the international Paris Climate Accord. Global warming is a serious threat - especially to a state like #Florida with two coastlines vulnerable to rising waters. #Sayfie— Rep. Vern Buchanan (@VernBuchanan) May 2, 2019
Some green groups applauded Thursday's vote. Sierra Club Executive Director Michael Brune called the bill "an important opportunity for every member of Congress to affirm on the record that the U.S. must be a leader in addressing the climate crisis."
Others argued that it did not go far enough.
"The latest science is clear: In order to adequately address deepening climate chaos, we must transition completely to clean, renewable energy generation in little more than a decade," Food & Water Watch Executive Director Wenonah Hauter said ahead of the vote. "The terms of the Paris accord aren't low-hanging fruit, they're fruit that has fallen to the ground and begun to rot."
Today the House of Representatives will vote on a bill to require the U.S. to remain in the Paris Climate Agreement. This is nowhere near the action we need.— Food & Water Watch (@foodandwater) May 2, 2019

Scientists have said that if all the world's countries met their pledges under the Paris agreement, it would not be enough to prevent a dangerous rise in temperature, The New York Times reported.
Democratic Representative Alexandria Ocasio-Cortez, who has championed a more ambitious Green New Deal that would transition the U.S. to net zero emissions within 10 years, said Thursday's act needed to be the precursor to more legislation.
"The idea that we can just reintroduce 2009 policies is not reflective of action that is necessary for now in the world of today," she said.
2009 was the last year that the House passed major climate change legislation, according to The New York Times. That bill would have put a cap on U.S. emissions and let businesses and utilities trade permits to emit, but it failed to advance in the Senate.

Hanako, a female Asian elephant, lived in a tiny concrete enclosure at Japan's Inokashira Park Zoo for more than 60 years, often in chains, with no stimulation. In the wild, elephants live in herds, with close family ties. Hanako was solitary for the last decade of her life.

Affecting Health and Altering Behavior<p>It is easy to observe the overall health and psychological consequences of life in captivity for these animals. Many captive elephants suffer from arthritis, obesity or skin problems. Both <a href="https://doi.org/10.11609/JoTT.o2620.1826-36" target="_blank">elephants</a> and orcas often have severe dental problems. Captive orcas are plagued by <a href="https://doi.org/10.1016/j.jveb.2019.05.005" target="_blank">pneumonia, kidney disease, gastrointestinal illnesses and infections</a>.</p><p>Many animals <a href="https://doi.org/10.1016/j.neubiorev.2017.09.010" target="_blank">try to cope</a> with captivity by adopting abnormal behaviors. Some develop "<a href="https://doi.org/10.1016/j.applanim.2017.05.003" target="_blank" rel="noopener noreferrer">stereotypies</a>," which are repetitive, purposeless habits such as constantly bobbing their heads, swaying incessantly or chewing on the bars of their cages. Others, especially big cats, pace their enclosures. Elephants rub or break their tusks.</p>
Changing Brain Structure<p>Neuroscientific research indicates that living in an impoverished, stressful captive environment <a href="https://doi.org/10.1016/j.jveb.2019.05.005" target="_blank" rel="noopener noreferrer">physically damages the brain</a>. These changes have been documented in many <a href="https://doi.org/10.1002/cne.903270108" target="_blank" rel="noopener noreferrer">species</a>, including rodents, rabbits, cats and <a href="https://doi.org/10.1006/nimg.2001.0917" target="_blank" rel="noopener noreferrer">humans</a>.</p><p>Although researchers have directly studied some animal brains, most of what we know comes from observing animal behavior, analyzing stress hormone levels in the blood and applying knowledge gained from a half-century of neuroscience research. Laboratory research also suggests that mammals in a zoo or aquarium have compromised brain function.</p>
This illustration shows differences in the brain's cerebral cortex in animals held in impoverished (captive) and enriched (natural) environments. Impoverishment results in thinning of the cortex, a decreased blood supply, less support for neurons and decreased connectivity among neurons. Arnold B. Scheibel, CC BY-ND<p>Subsisting in confined, barren quarters that lack intellectual stimulation or appropriate social contact seems to <a href="https://doi.org/10.1590/S0001-37652001000200006" target="_blank" rel="noopener noreferrer">thin the cerebral cortex</a> – the part of the brain involved in voluntary movement and higher cognitive function, including memory, planning and decision-making.</p><p>There are other consequences. Capillaries shrink, depriving the brain of the oxygen-rich blood it needs to survive. Neurons become smaller, and their dendrites – the branches that form connections with other neurons – become less complex, impairing communication within the brain. As a result, the cortical neurons in captive animals <a href="https://doi.org/10.1002/cne.901230110" target="_blank">process information less efficiently</a> than those living in <a href="https://doi.org/10.1002/dev.420020208" target="_blank">enriched, more natural environments</a>.</p>

Bob Jacobs, CC BY-ND<p>Brain health is also affected by living in small quarters that <a href="https://doi.org/10.3233/BPL-160040" target="_blank">don't allow for needed exercise</a>. Physical activity increases the flow of blood to the brain, which requires large amounts of oxygen. Exercise increases the production of new connections and <a href="http://dx.doi.org/10.1126/science.aaw2622" target="_blank">enhances cognitive abilities</a>.</p><p>In their native habits these animals must move to survive, covering great distances to forage or find a mate. Elephants typically travel anywhere from <a href="https://www.elephantsforafrica.org/elephant-facts/#:%7E:text=How%20far%20do%20elephants%20walk,km%20on%20a%20daily%20basis." target="_blank">15 to 120 miles per day</a>. In a zoo, they average <a href="https://doi.org/10.1371/journal.pone.0150331" target="_blank" rel="noopener noreferrer">three miles daily</a>, often walking back and forth in small enclosures. One free orca studied in Canada swam <a href="https://doi.org/10.1007/s00300-010-0958-x" target="_blank" rel="noopener noreferrer">up to 156 miles a day</a>; meanwhile, an average orca tank is about 10,000 times smaller than its <a href="https://www.cascadiaresearch.org/projects/killer-whales/using-dtags-study-acoustics-and-behavior-southern" target="_blank" rel="noopener noreferrer">natural home range</a>.</p>
Disrupting Brain Chemistry and Killing Cells<p>Living in enclosures that restrict or prevent normal behavior creates chronic frustration and boredom. In the wild, an animal's stress-response system helps it escape from danger. But captivity traps animals with <a href="https://doi.org/10.1073/pnas.1215502109" target="_blank">almost no control</a> over their environment.</p><p>These situations foster <a href="https://doi.org/10.1037/rev0000033" target="_blank">learned helplessness</a>, negatively impacting the <a href="https://doi.org/10.1155/2016/6391686" target="_blank" rel="noopener noreferrer">hippocampus</a>, which handles memory functions, and the <a href="https://doi.org/10.1016/j.neuropharm.2011.02.024" target="_blank" rel="noopener noreferrer">amygdala</a>, which processes emotions.

It also disrupts the <a href="https://doi.org/10.1016/j.neubiorev.2005.03.021" target="_blank" rel="noopener noreferrer">delicate balance of serotonin</a>, a neurotransmitter that stabilizes mood, among other functions.</p><p>In humans, <a href="https://doi.org/10.1006/nimg.2001.0917" target="_blank" rel="noopener noreferrer">deprivation</a> can trigger <a href="https://doi.org/10.3389/fnins.2018.00367" target="_blank" rel="noopener noreferrer">psychiatric issues</a>, including depression, anxiety, <a href="https://doi.org/10.3389/fnins.2018.00367" target="_blank" rel="noopener noreferrer">mood disorders</a> or <a href="https://doi.org/10.1177/1073858409333072" target="_blank" rel="noopener noreferrer">post-traumatic stress disorder</a>. <a href="https://doi.org/10.1007/s00429-010-0288-3" target="_blank" rel="noopener noreferrer">Elephants</a>, <a href="https://doi.org/10.1371/journal.pbio.0050139" target="_blank" rel="noopener noreferrer">orcas</a> and other animals with large brains are likely to react in similar ways to life in a severely stressful environment.</p>
Damaged Wiring<p>Captivity can damage the brain's complex circuitry, including the basal ganglia. This group of neurons communicates with the cerebral cortex along two networks: a direct pathway that enhances movement and behavior, and an indirect pathway that inhibits them.</p><p>The repetitive, <a href="http://dx.doi.org/10.1016/j.bbr.2014.05.057" target="_blank">stereotypic behaviors</a> that many animals adopt in captivity are caused by an imbalance of two neurotransmitters, dopamine and <a href="https://doi.org/10.1016/j.neubiorev.2010.02.004" target="_blank" rel="noopener noreferrer">serotonin</a>. This impairs the indirect pathway's ability to modulate movement, a condition documented in species from chickens, cows, sheep and horses to primates and big cats.</p>
The cerebral cortex, hippocampus and amygdala are physically altered by captivity, along with brain circuitry that involves the basal ganglia. Bob Jacobs, CC BY-ND<p>Evolution has constructed animal brains to be exquisitely responsive to their environment. Those reactions can affect neural function by <a href="https://www.penguinrandomhouse.com/books/311787/behave-by-robert-m-sapolsky/" target="_blank">turning different genes on or off</a>. Living in inappropriate or abusive circumstance alters biochemical processes: It disrupts the synthesis of proteins that build connections between brain cells and the neurotransmitters that facilitate communication among them.</p><p>There is strong evidence that <a href="https://doi.org/10.1523/JNEUROSCI.0577-11.2011" target="_blank">enrichment</a>, social contact and appropriate space in more natural habitats are <a href="https://doi.org/10.1111/j.1748-1090.2003.tb02071.x" target="_blank" rel="noopener noreferrer">necessary</a> for long-lived animals with large brains such as <a href="https://doi.org/10.1371/journal.pone.0152490" target="_blank" rel="noopener noreferrer">elephants</a> and <a href="https://doi.org/10.1080/13880292.2017.1309858" target="_blank" rel="noopener noreferrer">cetaceans</a>.

The Captivity Question<p>Some people defend keeping animals in captivity, arguing that it helps conserve endangered species or offers educational benefits for <a href="http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.574.3479&rep=rep1&type=pdf" target="_blank" rel="noopener noreferrer">visitors to zoos and aquariums</a>.

Maybe we can blame COVID-19 for making it hard to hit the streets and gather signatures to get initiatives on state ballots. But this year there are markedly fewer environmental issues up for vote than in 2018.
While the number of initiatives may be down, there's no less at stake. Voters will still have to make decisions about wildlife, renewable energy, oil companies and future elections.
Here's the rundown of what's happening where.
Return of an Apex Predator<p>Wolves are on the ballot in Colorado. <a href="https://leg.colorado.gov/ballots/reintroduction-and-management-gray-wolves" target="_blank" rel="noopener noreferrer">Proposition 114</a> would require the state's Parks and Wildlife Commission to create a plan by 2023 for the reintroduction and management of gray wolves (<em>Canis lupus</em>) in areas west of the continental divide.</p><p>Gray wolves once roamed across the western United States but were mostly eradicated by the 1930s. Slowly efforts are being made to bring them back. The reintroduction of gray wolves to Yellowstone National Park in 1996 has been hailed as a <a href="https://www.theguardian.com/environment/2020/jan/25/yellowstone-wolf-project-25th-anniversary" target="_blank" rel="noopener noreferrer">rewilding success</a>.</p><p>"The argument is that by putting back in wolves — an apex predator that has evolved alongside their prey species — we're putting things back into ecological balance," University of Colorado Boulder ecology professor Joanna Lambert <a href="https://therevelator.org/wolf-reintroduction-colorado/" target="_blank">told <em>The Revelator</em></a> in a February interview about the science behind wolf reintroductions.</p><p>The Rocky Mountain Elk Foundation and the Colorado Farm Bureau are two of the top donors to the opposition groups.</p><p>The measure does include compensation for losses of livestock caused by gray wolves.</p><p>"What we're all hoping for is a landscape where we can coexist with the species that were originally here, but also acknowledging that humans need to make a living and that the costs of this initiative will be felt by some folks more than others," Lambert said.</p>
Confusion Over Clean Energy<p>In Nevada voters will take a second swing at a constitutional amendment to require that electric utilities source 50% of their electricity from renewables by 2030. Voters passed the same measure, <a href="https://www.nvsos.gov/sos/home/showdocument?id=8826" target="_blank">Question 6</a>, in 2018, but state law requires that constitutional amendments be passed in two consecutive even-numbered election years.</p><p>More clean energy for the state may seem good. But there's concern that enshrining 50% renewables by 2030 in the state's constitution isn't that ambitious and it will make it harder to continue the push for 100% renewables in the future. To do that would be another constitutional amendment that would again take four years and two consecutive ballot wins to move the needle.</p><p>Also, the state is already on its way to the same renewable goal.</p><p>A legislative effort to achieve 50% renewables by 2030 — but with a slightly different timeline for the increments to get there — was signed into law in April 2019 by Nevada Gov. Steve Sisolak. Renewable advocates hope the state will do even better than that benchmark, but passing Question 6 would make it harder.</p>
Paying a Fair Share<p>If California's <a href="https://www.sos.ca.gov/elections/ballot-measures/qualified-ballot-measures/" target="_blank">Proposition 15</a> passes, commercial and industrial properties will need to start paying taxes based on their current market value, instead of paying based on the purchase price from decades prior (which stems from Proposition 13 passed back in 1978). The initiative would exempt agricultural land, small businesses, renters and homeowners.</p><p>Reassessing the worth of large commercial properties could bring in between $7.5 billion and $12 billion a year that would go toward supporting local governments, school districts and community colleges.</p><p>Most of the <a href="https://ballotpedia.org/California_Proposition_15,_Tax_on_Commercial_and_Industrial_Properties_for_Education_and_Local_Government_Funding_Initiative_(2020)" target="_blank">opposition</a> has come from big business and anti-taxation groups.</p><p>The California Teachers Association Issues PAC is the biggest supporter of the effort, but a number of <a href="https://www.yes15.org/endorsers-environment" target="_blank" rel="noopener noreferrer">environmental groups</a> have also endorsed the measure, which would likely see oil companies and other big industrial polluters having to kick in more money.</p><p>"The oil industry has used Prop. 13 loopholes to evade tens of millions of dollars in property taxes," <a href="https://www.nrdc.org/experts/victoria-rome/nrdc-announces-support-californias-proposition-15" target="_blank" rel="noopener noreferrer">wrote Victoria Lome</a>, California legislative director for the Natural Resources Defense Council. "Companies like Chevron, Exxon, Phillips 66, Shell and Tosco are paying taxes based on assessments taken prior to 2000. Prop. 15 would end this hidden subsidy to dirty energy."</p><p>Oil companies could stand to lose in Alaska, too. Voters there will weigh in on <a href="https://ballotpedia.org/Alaska_Ballot_Measure_1,_North_Slope_Oil_Production_Tax_Increase_Initiative_(2020)" target="_blank" rel="noopener noreferrer">Ballot Measure 1</a>, which would increase taxes on big oil producers (those that have produced more than 400 million barrels overall or 40,000 barrels a day in the past year) operating in three established oil fields in the North Slope.</p>
Taking the Wind Out of the Sails of the Electoral College<p>Colorado's <a href="https://leg.colorado.gov/ballots/adopt-agreement-elect-us-president-national-popular-vote" target="_blank">Proposition 113</a> isn't about environmental issues directly but could cause big shifts in how presidential elections are run and what states and issues are considered important.</p><p>The initiative would add Colorado to the <a href="https://www.nationalpopularvote.com/written-explanation" target="_blank">National Popular Vote Interstate Compact</a>. That effort is aimed at ensuring the presidential candidate who wins the popular vote wins the election. It doesn't eliminate the Electoral College, but it saps its power.</p><p>The compact needs states representing at least 270 Electoral College votes to go into effect. It's currently at 196.</p><p>If Colorado's proposition is passed, and if the National Popular Vote Interstate Compact eventually gets enough votes to go into effect, then Colorado's nine electoral votes would go to the presidential candidate who wins the popular vote, not to the one who gets the most votes in Colorado.</p>

The World Health Organization, along with its global partners in the fight against the COVID-19 pandemic, has announced that it will provide 120 million rapid-diagnostic antigen tests to people in lower- and middle-income countries over the next six months. The tests represent a "massive increase" in testing worldwide, according to the Global Fund, a partnership that works to end epidemics.
Quick Test Can Break Infection Chains<p>"These tests provide reliable results in approximately 15 to 30 minutes, rather than hours or days, at a lower price with less sophisticated equipment," said WHO head Tedros, adding that the tests would cost as little as $5 each, and could become cheaper still. He said the rapid tests would help expand testing to hard-to-reach areas which aren't as well-equipped, or which are lacking trained health workers.</p><p>"High-quality rapid tests show us where the virus is hiding, which is key to quickly tracing and isolating contacts and breaking the chains of transmission," said Tedros. "The tests are a critical tool for governments as they look to reopen economies and ultimately save both lives and livelihoods."</p><p>Catharina Boehme, head of FIND, also welcomed the widespread rollout of cheap test kits. "This really shows what can be achieved when the world and leading global health partners come together with a common priority," she said.</p>
How Do COVID-19 Antigen Tests Work?<p>There are currently three different types of coronavirus diagnostic tests on the market: antigen tests, polymerase chain reaction (PCR) tests and serology tests (ELISA). </p><p>Rapid antigen tests target virus proteins, and somewhat resemble pregnancy tests. They aren't yet available at pharmacies and can only be administered by trained medical personnel. With a nasal or throat swab, testers can find out within approximately 15 minutes whether a patient has contracted the SARS-CoV-2 virus and is infectious and must be quarantined.</p><p>The advantage of rapid antigen tests is that they can be conducted quickly and on the spot. <br></p><p>It's hoped that this will help save the lives of thousands of people and slow the spread of the pandemic in the world's poorest countries. Rapid antigen tests can be used to carry out mass screenings among health care workers in low-income countries, who are at greater risk of death from COVID-19. These tests could also be used in schools, in the workplace and in nursing and retirement homes.</p><p>The major disadvantage of rapid antigen tests is that they're less reliable than PCR tests, which are conducted in labs and designed to detect the virus' genetic material. Rapid antigen tests may also be less effective in detecting infections in the early stages.</p><p>Still, a growing number of medical experts are backing the mass rollout of antigen tests, as they allow infected people to be identified even before they show symptoms, when individuals have a high viral load and are especially infectious.</p>
Not All Rapid Test Kits Are Reliable<p>Hundreds of rapid COVID-19 test kits have come on the market recently. Many of them are reliable, but not all. In March, for example, Spain sent back two batches of unlicensed Chinese test kits because they were flawed.</p><p>The European Center for Disease Prevention and Control has pointed out that even though many tests have been approved for sale on the European market, very few clinical studies show whether they are actually effective.</p><p>The 120 million test kits set to be rolled out by the WHO are the first to meet all of the organization's standards; test makers SD BioSensor and Abbott were granted emergency approval by the WHO last week.</p><p>The manufacturers claim their tests are up to 97% reliable in lab conditions; in the real world, the tests are said to be between 80% and 90% reliable. While this is good, it also means some 20% of patients will receive negative results despite being infected, which could lead to further spread of the virus.</p>
What Are the Alternatives to Antigen Tests?<p>Rapid antigen tests are ideal to test scores of patients quickly, simply and cheaply. Lab-based PCR tests, however, are superior in terms of reliability.</p><p>The PCR test detects genetic material, or RNA, from the SARS-CoV-2 virus. Patients are asked to provide a throat swab. One part of the person's genetic material is then synthesized, after which a biochemical process known as agarose gel electrophoresis is used to detect if the sample contains virus RNA. These tests are highly reliable but can only be conducted in specialized labs.</p><p>Serologic testing, on the other hand, detects antibodies in a person's blood that form when the immune system responds to a certain pathogen. This indicates that a person has already been exposed to the virus. While quick test kits are available for this method, these are mainly used for scientific studies.<br></p>
The first presidential debate seemed like it would end without a mention of the climate crisis when moderator Chris Wallace brought it up at the end of the night for a segment that lasted roughly 10 minutes.
