Wildfires are sweeping BC. Close to 900 have burned through 600,000 hectares so far this year, blanketing western North America with smoke. Fighting them has cost more than $230 million—and the season is far from over.
It's not just BC. Thousands of people from BC to California have fled homes as fires rage. Greenland is experiencing the largest blaze ever recorded, one that Prof. Stef Lhermitte of Delft University in the Netherlands called "a rare and unusual event." Fires have spread throughout Europe, North America and elsewhere. In June, dozens of people died in what's being called Portugal's worst fire ever. Meanwhile, from Saskatchewan to Vietnam to New Zealand, floods have brought landslides, death and destruction.
What will it take to wake us up to the need to address climate change? Fires and floods have always been here, and are often nature's way of renewing ecosystems—but as the world warms, they're increasing in frequency, size and severity. Experts warn wildfires could double in number in the near future, with the Pacific Northwest seeing five or six times as many.
In the western U.S., annual average temperatures have increased by 2 C and the fire season has grown by three months since the 1970s, leading to "new era of western wildfires," according to a recent study led by University of Colorado Boulder wildfire experts, published in Proceedings of the National Academy of Sciences.
Climate change doesn't necessarily start the fires—lightning, unattended campfires, carelessly tossed cigarette butts and sparks from machinery are major causes—but it creates conditions for more and larger fires. Lightning, which causes up to 35 percent of Canada's wildfires and is responsible for 85 percent of the area burned annually, increases as temperatures rise, with studies showing 12 percent more lightning strikes for each degree Celsius of warming.
Drier, shorter winters and earlier snowmelt extend fire seasons. As the atmosphere warms, it holds more moisture, some of which it draws from forests and wetlands, and increasing precipitation is not enough to offset the drying. This means fuel sources ignite more easily and fires spread faster over greater areas. Outbreaks of pests such as mountain pine beetles—previously kept in check by longer, colder winters—have also killed and dried forests, adding fuel to the fires. Because trees and soils hold moisture on slopes, fires can also increase the risk of flash floods when rains finally arrive.
The human and economic impacts are staggering—from property destruction to firefighting and prevention to loss of valuable resources and ecosystems. As human populations expand further into wild areas, damages and costs are increasing.
Health impacts from smoke put people—especially children and the elderly—at risk and drive health care costs up. Wildfires now kill more than 340,000 people a year, mainly from smoke inhalation.
Fires also emit CO2, creating feedback loops and exacerbating climate change. Boreal forests in Canada and Russia store large amounts of carbon and help regulate the climate, but they're especially vulnerable to wildfires.
Suggested solutions are wide-ranging. The authors of the PNAS study recommend letting some wildfires burn in areas uninhabited by people, setting more "controlled" fires to reduce undergrowth fuels and create barriers, thinning dense forests, discouraging development in fire-prone areas and strengthening building codes.
These adaptive measures are important, as are methods to prevent people from sparking fires, but our primary focus should be on doing all we can to slow global warming.
According to NASA, Earth's average surface temperature has risen by 1.1 C since the late 19th century, with most warming occurring over the past 35 years, and 16 of the 17 warmest years occurring since 2001. Eight months of 2016 were the warmest on record. Oceans have also been warming and acidifying quickly, Arctic ice has rapidly decreased in extent and thickness, glaciers are retreating worldwide, and sea levels have been rising at an accelerating pace. Record high temperature events have been increasing while low temperature events have decreased, and extreme weather events are becoming more common in many areas.
Today's wildfires are a wake-up call. If we are serious about our Paris agreement commitments, we can't build more pipelines, expand oil sands, continue fracking or exploit extreme Arctic and deep-sea oil.

The American Society of Civil Engineers (ASCE) gave America's infrastructure a C- grade in its quadrennial assessment issued March 3. ASCE gave the nation's flood control infrastructure – dams and levees – a D grade. This is a highly concerning assessment, given that climate change is increasingly stressing dams and levees as increased evaporation from the oceans drives heavier precipitation events.

On Wednesday, the Department of the Interior (DOI) announced that it will be rescinding secretarial order 3369, which sidelined scientific research and its use in the agency's decisions. Put in place by the previous administration, the secretarial order restricted decisionmakers at the DOI from using scientific studies that did not make all data publicly available.
Science Rising at Interior
<p>The rescinded secretarial order is not the only notable victory we have seen from the DOI recently. The Biden administration has moved swiftly to <a href="https://www.nytimes.com/2021/03/02/climate/biden-interior-department-haaland.html" target="_blank">restore consideration of climate change</a> in its decisions, <a href="https://www.nationalgeographic.com/environment/article/biden-expected-to-reverse-trump-order-to-shrink-utah-national-monuments" target="_blank">reverse assaults on our public lands</a>, and <a href="https://www.audubon.org/news/biden-halts-trump-rule-gutted-landmark-bird-protection-law" target="_blank">taken actions to protect our nation's wildlife</a>. These decisions, unlike many made at the DOI over the past four years, have been informed by science—and President Biden's pick to lead the DOI, Representative Deb Haaland of New Mexico, has <a href="https://www.cnn.com/2021/02/22/politics/haaland-confirmation-remarks/index.html" target="_blank">promised in her confirmation hearing</a> to continue to make decisions that are guided by science.</p><p><strong>Saving Migratory Birds</strong></p><p>One of the parting gifts of the prior administration was a <a href="https://blog.ucsusa.org/jacob-carter/outgoing-administration-gave-thumbs-up-to-migratory-bird-massacre-its-time-to-reverse-the-damage" target="_blank">reinterpretation of a long-standing rule that protected migratory bird species</a>. For decades, the <a href="https://www.fws.gov/birds/policies-and-regulations/laws-legislations/migratory-bird-treaty-act.php" target="_blank" rel="noopener noreferrer">Migratory Bird Treaty Act</a> (MBTA) had protected migratory bird species, which are in decline in the US, by allowing the DOI to fine industries that failed to take proper precautions to protect migratory birds. For example, <a href="https://www.fws.gov/birds/bird-enthusiasts/threats-to-birds/entrapment-entanglement-drowning.php#:~:text=An%20estimated%20500%2C000%20to%201,trays%2C%20and%201%25%20spills." target="_blank" rel="noopener noreferrer">not placing proper netting over oil pits</a>, which can result in the death of migratory birds. The rule, however, was reinterpreted by the prior administration such that industries could only be fined if bird deaths were "intentional" and not if they occurred incidentally due to a lack of precautions.</p><p>The prior administration, in its final days, also <a href="https://www.motherjones.com/environment/2021/03/endangered-species-recovery-interior-deb-haaland/" target="_blank" rel="noopener noreferrer">eliminated protections for the northern spotted owl</a>, which is currently listed by the Fish and Wildlife Service (FWS) as a threatened species. More than 3 million acres of the owl's habitat were removed from protection to pave way for timber harvesting. Susan Jane Brown, a staff attorney at the Western Environmental Law Center, <a href="https://www.nytimes.com/2021/03/02/climate/biden-interior-department-haaland.html" target="_blank" rel="noopener noreferrer">stated that she had received</a> "…several calls from wildlife biologists who are in tears who said, 'Did you know this is happening? The bird won't survive this."</p><p>The Biden administration, following the best available science, has delayed the implementation of both rules.</p><p><strong>Restoring Public Lands</strong></p><p>In 2017, two national monuments, Bears Ears and Grand Staircase-Escalante of Utah, <a href="https://www.nytimes.com/2017/12/04/us/trump-bears-ears.html" target="_blank" rel="noopener noreferrer">were reduced in size by some two million acres</a>, the largest reduction of federal land protection in our nation's history. Later, <a href="https://www.nytimes.com/2018/03/02/climate/bears-ears-national-monument.html" target="_blank" rel="noopener noreferrer">internal emails at the DOI</a> would show that these actions were not a product of following the best available science, and were instead guided by a push to exploit oil and natural gas deposits within the boundaries of the protected land. In particular, the decision did not consider the archaeological importance of the protected lands or their cultural heritage. Sidelining these facets of this decision is likely what <a href="https://www.motherjones.com/environment/2021/02/biden-orders-review-of-trumps-assaults-on-americas-natural-treasures/?utm_source=twitter&utm_campaign=naytev&utm_medium=social" target="_blank" rel="noopener noreferrer">prompted a review of the reductions</a> by the Biden administration.</p>Bringing Science Back Across the Administration
<p>Beyond the Interior department, the Biden administration has taken quick steps to bring science back to the forefront of decisionmaking across the federal government. In January, President Biden signed a <a href="https://www.whitehouse.gov/briefing-room/presidential-actions/2021/01/27/memorandum-on-restoring-trust-in-government-through-scientific-integrity-and-evidence-based-policymaking/" target="_blank" rel="noopener noreferrer">presidential memo</a> to strengthen scientific integrity and evidence-based decisionmaking. The memo, among many other positive steps for science, has initiated a review process on scientific integrity policies that should be finalized toward the end of the year. Given the <a href="https://www.ucsusa.org/resources/attacks-on-science" target="_blank" rel="noopener noreferrer">unprecedented number of times we documented political interference in science-based decision-making processes</a> over the past four years, such a review, and the subsequent recommendations arising from it, are clearly warranted.</p><p>The Biden administration also has formed multiple scientific advisory groups to help make choices informed by the best available science to protect public health and our environment. This includes advisory groups on critical issues such as <a href="https://www.whitehouse.gov/briefing-room/presidential-actions/2021/01/27/memorandum-on-restoring-trust-in-government-through-scientific-integrity-and-evidence-based-policymaking/" target="_blank" rel="noopener noreferrer">scientific integrity</a>, <a href="https://www.whitehouse.gov/briefing-room/press-briefings/2021/02/10/president-biden-announces-members-of-the-biden-harris-administration-covid-19-health-equity-task-force/" target="_blank" rel="noopener noreferrer">COVID-19</a>, and <a href="https://www.americanprogress.org/issues/green/reports/2021/02/04/495397/mapping-environmental-justice-biden-harris-administration/" target="_blank" rel="noopener noreferrer">environmental justice</a>. The administration also is moving quickly to <a href="https://www.npr.org/sections/biden-transition-updates/2020/12/17/938092644/biden-to-pick-north-carolina-regulator-michael-regan-to-lead-epa" target="_blank" rel="noopener noreferrer">appoint qualified leaders</a> at science-based agencies and has asked the heads of agencies to expeditiously establish scientific integrity officials and chief science officers.</p><p>In addition to rescinding the secretarial order at DOI, the Biden administration has also rescinded several other anti-science actions taken over the past four years. Among the <a href="https://www.whitehouse.gov/briefing-room/presidential-actions/2021/02/24/executive-order-on-the-revocation-of-certain-presidential-actions/" target="_blank" rel="noopener noreferrer">many anti-science executive orders reversed by President Biden are </a>an order that directed agencies to arbitrarily cut their advisory committees by one-third and another that required agencies to cut two regulations for every new regulation they issued.</p><p>There has been a lot of progress for science-based decisionmaking over the past six weeks, with more expected as qualified individuals are appointed to head science-based agencies. And yet we know through our research that <a href="https://www.sciencepolicyjournal.org/uploads/5/4/3/4/5434385/berman_emily__carter_jacob.pdf" target="_blank" rel="noopener noreferrer">every administration has politicized science-based decisionmaking to some extent</a>.</p><p>We will continue to watch, demand, and ensure that science guides the critical decisions being made by the Biden administration. Our health, our environment, and our safety depend on it.</p><p><em><a href="https://blog.ucsusa.org/author/jacob-carter#.YED_bRNKjt0" target="_blank">Jacob Carter</a> is a research scientist for the Center for Science and Democracy at the Union of Concerned Scientists.</em></p><p><em>Reposted with permission from the <em><a href="https://blog.ucsusa.org/jacob-carter/science-wins-at-the-interior-department" target="_blank">Union of Concerned Scientists</a>.</em></em></p>At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.

<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>Avocado and almond crops depend on bees for proper pollination.

<p>Salazar and other Columbian beekeepers described "scooping up piles of dead bees" year after year since the avocado and citrus booms began, according to Phys.org. Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>Six major U.S. electricity utilities will collaborate to build a massive EV charging network across 16 states, they announced Tuesday.
