Antarctica Experiences First Known Heat Wave
By Richard Connor
Scientists have recorded Antarctica's first documented heat wave, warning that animal and plant life on the isolated continent could be drastically affected by climate change.
Australian Antarctic Program researchers recorded the heat wave event at Casey research station in East Antarctica during the 2019-2020 southern hemisphere summer.
Findings by the team were published in the Global Change Biology journal on Tuesday, with authors warning that the changes could affect global weather patterns.
Between January 23 and 26, a research team at Casey — directly south of Perth in western Australia — recorded the highest maximum and minimum temperatures ever seen at the base.
During the period, minimum temperatures were higher than zero degrees Celsius (32 degrees Fahrenheit) while the maximums peaked above 7.5 degrees.
On January 24, the Casey team recorded a record high temperature of 9.2 degrees Celsius, 6.9 degrees higher than the station's mean maximum.
Heat waves are classified as three consecutive days where very high maximum and minimum temperatures are recorded.
At the same time, record high temperatures were also reported on the other side of the continent, on the Antarctic Peninsula. Last month, the highest ever temperature — 18.3 degrees — was recorded at the Argentinian research station Esperanza Base.
Global Impact on Climate
The authors of the study said the local effects of climate change could have a global impact.
"Antarctica may be isolated from the rest of the continents by the Southern Ocean, but it has worldwide impacts," they said.
"It drives the global ocean conveyor belt, a constant system of deep-ocean circulation which transfers oceanic heat around the planet, and its melting ice sheet adds to global sea-level rise."
Co-author Dana Bergstrom said the hot summer could affect local populations positively at first, but could also lead to drought and heat stress on species adapted for the cold.
"Most life exists in small ice-free oases in Antarctica, and depends on melting snow and ice for their water supply," said Bergstrom, a principal scientist at the Australian Antarctic Division.
While an increase in meltwater flooding associated with higher temperatures could provide extra water to such ecosystems – helping them on a short-term basis - it could also dislodge plants and radically change the composition of communities of invertebrates and microbes.
"Based on our experience from previous anomalous hot summers in Antarctica we can expect a multitude of biological impacts to be reported in coming years, illustrating how climate change is impacting even the most remote areas of the planet," the study said.
Contributors to the research came from Australia's University of Wollongong, the University of Tasmania and the government agency Australian Antarctic Division.

When President Donald Trump visited California on September 14 and dismissed the state Secretary of Natural Resources Wade Crowfoot's plea to recognize the role of climate change in the midst of the Golden State's worst and most dangerous recorded fire season to date, he gaslighted the tens of millions of West Coast residents suffering through the ordeal.
Foxes Guarding the Henhouse<p>Before he assumed power, Trump attacked regulations as unnecessary barriers to freedom and economic prosperity. Since taking office, he has targeted anything enacted by the administration of his predecessor, Barack Obama, and taken steps to withdraw the U.S. from the Paris agreement, the international effort to combat climate change. He has also staffed heads of key agencies with climate deniers of various stripes, forced out career public servants and created a hostile work environment for those who don't profess loyalty to his deregulatory agenda.</p><p>Like Trump himself, some of his cabinet choices displayed an audacious penchant for <a href="https://www.nytimes.com/interactive/2020/09/27/us/donald-trump-taxes.html?action=click&module=Spotlight&pgtype=Homepage" target="_blank">self-dealing</a> and abusing their positions of authority. One example is Trump's first Environmental Protection Agency (EPA) Administrator, Scott Pruitt, who aggressively worked to overturn Obama's climate regulations, spent most of his time in <a href="https://www.washingtonpost.com/national/health-science/trump-epa-head-steps-down-after-wave-of-ethics-management-scandals/2018/07/05/39f4251a-6813-11e8-bea7-c8eb28bc52b1_story.html" target="_blank" rel="noopener noreferrer">private meetings</a> with fossil fuel and chemical company executives, sidelined career EPA staff and reconfigured independent scientific advisory boards to make them more supportive of the industries EPA is charged with regulating. Dubbed "<a href="https://www.latimes.com/politics/la-na-pol-pruitt-leaves-20180705-story.html" target="_blank" rel="noopener noreferrer">one of the most scandal-plagued Cabinet officials in U.S. history</a>," Pruitt resigned in disgrace after revelations about his multiple brazen abuses, including using the agency as his personal concierge service and piggy bank.</p><p>Pruitt's deputy, Andrew Wheeler, a <a href="https://www.cbsnews.com/news/andrew-wheeler-acting-epa-administrator-former-number-two-before-scott-pruitt-resignation/" target="_blank">former coal industry lobbyist</a> and longtime Republican Washington insider, took over and has continued Trump's deregulatory agenda apace.</p><p>At the Department of Interior (DOI), a sprawling agency that oversees 75 percent of the country's public federal lands and includes the U.S. Geological Survey, which is tasked with evaluating natural hazards that threaten life and the health of our ecosystems, Trump installed another flamboyant anti-environmentalist to head the agency. Like Pruitt, Trump's first Interior Secretary Ryan Zinke aggressively attacked environmental regulations, <a href="https://www.washingtonpost.com/news/energy-environment/wp/2017/05/07/epa-dismisses-half-of-its-scientific-advisers-on-key-board-citing-clean-break-with-obama-administration/" target="_blank">ditched more than 200 advisory panels</a>, and pushed to open up vast swaths of public land to oil and gas drilling. Described by one environmental group as "<a href="https://www.washingtonpost.com/national/health-science/interior-secretary-zinke-resigns-amid-investigations/2018/12/15/481f9104-0077-11e9-ad40-cdfd0e0dd65a_story.html" target="_blank" rel="noopener noreferrer">the most anti-conservation Interior secretary in our nation's history</a>," Zinke was forced out after numerous highly publicized conflict-of-interest scandals.</p><p>The DOI is now run by Zinke's deputy secretary, David Bernhardt, another longtime Republican Washington insider and former oil industry lobbyist who has also been the subject of <a href="https://slate.com/news-and-politics/2020/05/this-is-still-happening-david-bernhardt-trump-lincoln.html" target="_blank">several government ethics complaints</a> for various violations favoring polluting industries.</p><p>More recently, longtime climate change denier David Legates, a climatologist at the University of Delaware previously <a href="https://insideclimatenews.org/news/19032015/u-delaware-refuses-disclose-funding-sources-its-climate-contrarian" target="_blank">funded by fossil fuel interests</a>, was hired for a <a href="https://www.npr.org/2020/09/12/912301325/longtime-climate-science-denier-hired-at-noaa" target="_blank" rel="noopener noreferrer">top job</a> advancing weather modeling and prediction at the National Oceanic and Atmospheric Administration (NOAA). Legates has called for <a href="https://www.democracynow.org/2020/9/18/noaa_david_legates_climate_crisis" target="_blank" rel="noopener noreferrer">increasing carbon emissions</a>.</p><p>The Trump administration has done much more than stack government agencies with fossil fuel industry proponents. It has removed or diluted discussion of climate change from as many government platforms as it can and decimated independent scientific advisory boards that provide unbiased, fact-based information the government needs to enact policies that protect the public. It has also <a href="https://thehill.com/policy/energy-environment/482352-trump-budget-slashes-funding-for-epa-environmental-programs" target="_blank" rel="noopener noreferrer">slashed environmental agency staffing and budgets</a>.</p>
The Damage So Far<p>A September 17 <a href="https://rhg.com/research/the-rollback-of-us-climate-policy/" target="_blank">report</a> by the Rhodium Group calculates that 1.8 billion tons more greenhouse gases will be released over the next 15 years as a result of climate change rollbacks the Trump administration has achieved so far. These include repealing Obama's main climate policy, the Clean Power Plan, which was intended to reduce dirty emissions from power plants; increasing pollution from cars by rolling back fuel economy standards and challenging California's longtime authority to set stricter emissions standards; targeting controls on hydrofluorocarbons, powerful greenhouse gases used mainly in refrigerators and air conditioners that also destroy the Earth's protective ozone layer; and allowing unreported and unregulated emissions of methane, another potent greenhouse gas, by oil and gas companies.</p><p>Besides these measures, Trump is also trying to gut core environmental statutes like the Clean Air Act, the Clean Water Act, the National Environmental Policy Act and the Endangered Species Act, all of which were enacted to protect human health and preserve a livable world.</p><p>The Paris agreement aims to keep the rise in average global temperatures at less than 2 degrees Celsius above pre-industrial levels and hopefully cap it at 1.5 degrees C or lower. We are now at approximately 1.2 degrees C and counting.</p>

It wasn't so long ago that the issue of climate change was poised to play a huge – possibly even a decisive – role in the 2020 election, especially in the race for control of the U.S. Senate. Many people supporting Democratic candidates saw a possible Democratic majority as a hedge against a potential Trump re-election … a way to plug the firehose spray of more than 100 environmental regulation rollbacks and new anti-climate initiatives by the administration over its first term.
Potential Climate Voters<p>In a September 1 memo on climate and the election, Andrew Baumann, vice president of the consultants Global Strategy Group, wrote: "Few issues have seen as dramatic a shift in public opinion as climate change has over the last few years. Only marriage equality and the recent shift in views around racial justice outpace the rapid growth in the salience of climate change as an issue."</p><p>Calling it a "winning political issue" the memo says: "First, it is clearly a motivator for both younger and Latinx voters. Second, it has the power to move swing voters, particularly center-right white women."</p><p>Baumann points to a finding that when a group of such women were asked generic ballot questions, Democrats trailed by nine percentage points. But when the question was revised as a choice between:</p><p>"A Democrat who supports taking strong government action to combat climate change.<br>A Republican who opposes taking strong government action to combat climate change."</p><p>… the result was a 29 percentage point shift, putting Democrats ahead by 20 percentage points among that same group.</p><p>"I think it is playing a role," says Senator Sheldon Whitehouse, D-RI, a longtime outspoken climate activist who is on the Senate Environment and Public Works Committee and also on the Senate Democrats' Special Committee on the Climate Crisis. If Democrats win back the Senate, he stands to play an even more pivotal climate role as part of the majority. He is not up for re-election this year.</p><p><span></span>"I think from the Democratic side it's playing a role in generating enthusiasm – particularly making younger voters feel that they have a real stake in this election. On the Republican side, I think things have moved enough that candidates can no longer get away with simply scoffing about climate change."</p>
Climate a Top Concern for Youths, Latinx<p>So who's still thinking climate? Mostly young voters – 18 to 25 or 29 and Latinx voters.</p><p>Climate and the environment are the top concern among young voters, just above racism and healthcare according to <a href="https://circle.tufts.edu/latest-research/poll-young-people-believe-they-can-lead-change-unprecedented-election-cycle" target="_blank" rel="noopener noreferrer">CIRCLE</a>, the Center for Information and Research on Civic Learning and Engagement at Tufts University, which focuses on the political life of young people in the U.S. For Latinx youth, it drops a bit but remains in the top three.</p><p>The issues young people care about have an impact on how they volunteer their time, says Kristian Lundberg, an associate researcher at CIRCLE. He says that's played out most notably through the Sunrise Movement, which focuses on climate change and the environment along with other key activist groups such as Black Lives Matter and March for Our Lives.</p><p>He points to polling this summer that showed that 83% of 18-to-29-year-olds felt they had the power to change things. "Young people feel much more empowerment than in 2016 and 2018," Lundberg says. "It's intentional these movements are carving out space for young people. It's an important strategy."</p><p>In positions of power in these organizations, young people have developed peer-to-peer outreach on activism. And Lundberg says young people have made the leap that connects activism to voting as a lever for change. "In the past in very close races, young people breaking heavily have provided the margin of victory," he says.</p><p>CIRCLE is highlighting 10 U.S. Senate races as ones in which young voters can be decisive. Several of them have notable climate or environmental components – most prominently the Colorado and Montana races.</p><p>The Republican incumbents in each state – Cory Gardner in Colorado and Steve Daines in Montana – are running against a popular Democratic governor – John Hickenlooper in Colorado, now out of office — and Steve Bullock, still the governor of Montana. Both governors have had to balance their state's fossil fuel economic interests with supporting climate change solutions.</p>
Tying Climate Change to the Economy<p>In August, Data for Progress, a progressive research think tank, released polling on climate change – including in the battleground Senate elections in Arizona, Iowa, Maine, and North Carolina – showing voters back a Senate candidate supporting strong climate action.</p><blockquote>Climate change as 'mobilizing issue … key persuasion issue.'<br></blockquote><p>It also showed that linking climate change to the economy may be key. That means talking about clean energy and jobs together, says Danielle Deiseroth, climate data analyst for <a href="https://circle.tufts.edu/latest-research/poll-young-people-believe-they-can-lead-change-unprecedented-election-cycle" target="_blank">Data for Progress</a>. She says that in addition to jobs, climate change issues include climate justice and economic equality – both of heightened interest because of fallout from western wildfires.</p><p>"Climate change, we've observed over the last year or so, is a key mobilizing issue and a key persuasion issue," she says. "Climate issues can only grow support for Democratic candidates.</p><p>"I think it's pretty naive to say climate is the key issue for voters. For a lot of voters it really exemplifies so many things that are wrong with the Trump presidency," Deiseroth says.</p><p>So a factor among others. Helpful, but pivotal only in narrow circumstances.</p><p>At the League of Conservations Voters, a progressive environmentalist organization putting a lot of money and effort into the 2020 races, Senior Director of Political Affairs Craig Auster says: "I'll push back that climate change doesn't matter or isn't registering."</p><p>"It's still showing up in several Senate races. It's been playing a role in almost all of them."</p><p>Candidates are still talking about it, he says, pointing to Colorado, Montana, Iowa, and other states where ads are addressing climate and environmental issues. That shows the candidates believe their opponent is vulnerable on the issue or they're strong on it, he says.</p><p>Like others, Auster calls climate a motivator.</p><p>"Climate change matters," he says. "We have proof point after proof point about what's happening, whether it's a hurricane, a superstorm, derechos in Iowa, or wildfires out west.</p><p>"Pre-COVID it was top tier for Democratic voters along with healthcare. If COVID didn't happen I think climate would be a big deal."</p>
