In short:

  • Environmental advocates argue that the construction of groins could harm the North Inlet-Winyah Bay reserve by disrupting natural sand movement.
  • Debidue Beach residents advocate for these structures to protect their homes from increasing erosion, highlighting tensions between climate resilience and coastal development.
  • Legal challenges and confusion over state coastal management regulations underscore the difficulties of balancing property protection with environmental conservation.

Key quote:

"Equity plays a huge part in this. When you look at environmental justice communities throughout the United States, you see an intentional disinvestment in those communities."

— Omar Muhammad, executive director of the Lowcountry Alliance for Model Communities

Why this matters:

By preserving beaches, groins also support local economies that depend on tourism. On the other hand, groins can have unintended consequences. For instance, while they may accumulate sand on one side, they can also starve areas down drift of sand, leading to increased erosion elsewhere.

Disparate state, local, private and federal conservation efforts are failing to protect biodiversity. Connectivity and coordination would help, say agency scientists and conservation leaders.

3 policy-aligned progressives vie to replace U.S. Rep. Earl Blumenauer in 3rd Congressional District

The winner of the May 21 Democratic primary is likely to cruise to victory in November, as registered Democrats outnumber Republicans in the district by more than 3-to-1.

The trio of progressive Portland-area Democrats leading the race to succeed U.S. Rep. Earl Blumenauer in Congress are barely distinguishable from each other when it comes to policy positions.But each of the candidates say they have a track record and leadership style that best qualify them to replace Blumenauer, an influential lawmaker who climbed to significant influence during his nearly 30 years in the U.S. House. All three are current or former elected officeholders with experience representing parts of Oregon’s 3rd Congressional District, which stretches from the Willamette River to Hood River.Eddy Morales, a Gresham city councilor and former Washington D.C.-based organizer, is emphasizing his plans to build affordable housing and overhaul the U.S. immigration system. Former Multnomah County Commissioner and corporate lawyer Susheela Jayapal says she’ll seek more federal investment for housing, homelessness services and climate change. State Rep. Maxine Dexter, a medical doctor whose district includes the west side of Portland, is calling for health care reforms as well as investment in housing, homelessness and clean energy.It’s likely the winner of the May 21 Democratic primary will cruise to election in November. Registered Democrats outnumber registered Republicans in the district more than 3-to-1.The seat is open for the first time in a generation after Blumenauer, 75, announced his retirement last spring. He handily won reelection 13 times after his first successful campaign in 1996.If elected, the three front-runners all said they would join the Congressional Progressive Caucus, which is chaired by Jayapal’s sister, U.S. Rep. Pramila Jayapal of Washington.They also share support for the Green New Deal, reproductive rights and Medicaid for All, although Dexter says smaller reforms are first needed to pave the way for single-payer health care. So far, the candidates have found common ground in polite debates.But they say differing personal, professional and electoral track records set them apart in important ways.Dexter, 51, was raised in a working-class family in Washington state. She is a practicing critical care physician and pulmonologist in Kaiser Permanente hospitals and is in her second full term in the Oregon House. She is supported by Democratic state lawmakers, the American Medical Association and gun control advocacy groups.As the chair of the House Committee on Housing and Homelessness, Dexter helped pass major investments in affordable housing and rental assistance championed by Gov. Tina Kotek. She has also sponsored legislation that ramped up the distribution of a life-saving opioid overdose reversal medication and banned restaurants’ use of Styrofoam takeout containers.Jayapal, 61, was born in India and moved to the U.S. when she was 16 to attend college. She was general counsel for Adidas until 2000 and since served on a slew of nonprofit boards. She began representing Northeast Portland on the Multnomah County Commission in 2019.Jayapal pitches herself as a strong progressive and coalition-builder. As a county commissioner, she says she helped increase rent assistance for low-income families. She also pushed a program that helps residents replace wood stoves with climate-friendly heat pumps and enthusiastically supported the county’s $51 billion lawsuit against oil and gas companies over the deadly 2021 heat dome. Jayapal is endorsed by environmental groups, Multnomah County Commission Chair Jessica Vega Pederson and Vermont Sen. Bernie Sanders.Morales, 44, was raised in Woodburn and Portland by an immigrant mother from Mexico. A gay man, he could be Oregon’s first out LGBTQ member of Congress. In the 5th District, Jamie McLeod-Skinner, a lesbian, is one of two Democrats seeking the party’s nomination.Morales spent more than a decade organizing voters and says he helped generate key support for the Affordable Care Act and youth immigrant “dreamers.” A city councilor in Gresham since 2019, he touts the city’s development of affordable housing complexes and a program to reduce youth gun violence during his tenure. He is endorsed by a bevy of labor unions, the LGBTQ+ Victory Fund, Georgia voting rights advocate Stacey Abrams and nine state lawmakers.Campaign financeAs of March 30, the most recent data available, Jayapal had raised $611,000, the most of any candidate, federal records show. Morales had raised $494,000 and Dexter had pulled in $338,000. All three have raised funds from a mix of individual donors and liberal political committees, according to the nonprofit analysis site Open Secrets.Dexter, however, is buoyed by a notably mammoth $1.25 million from the 314 Action Fund, a political action committee that aims to elect progressives with backgrounds in science.No other committee is independently spending to support or oppose the other candidates, according to Open Secrets. Last year, some observers speculated that pro-Israel political groups would oppose Jayapal over her brief reluctance to condemn Hamas for the group’s Oct. 7 attack. Jayapal has since criticized Hamas while calling for a ceasefire amid Israel’s brutal response. Morales and Dexter offered similar statements this spring, and pro-Israel spending in the contest has not materialized.Sarah Bryner, director of research and strategy at Open Secrets, said spending could intensify as the primary approaches.Michael Jonas, a Portland attorney and owner of Rational Unicorn Legal Services, is also vying for the Democratic nomination. He has raised about $16,000 and touts endorsements from metro-area LGBTQ organizations, civic leaders and entrepreneurs. Other Democratic candidates are Ricardo Barajas, Nolan Bylenga and Rachel Lydia Rand.In the Republican primary, attorney Joanna Harbour has raised $6,000 in direct donations. A perennial candidate, she captured about a quarter of votes cast when running against Blumenauer in 2020 and 2022. Two other Republicans, Gary Dye and Teresa Orwig, are also running for the nomination.The 3rd District seat is up for grabs for the first time since 1996, when Blumenauer was first elected. He spent 28 years in the U.S. House and rose through the ranks to become a member of the influential Ways and Means committee, which writes tax bills and oversees government programs including Social Security and Medicare. He is a member of the Congressional Progressive Caucus.Any of the three front-runners would enter Congress with far less influence than Blumenauer. However, Jayapal said it’s “certainly possible” that constituents would benefit from her close relationship with her sister.“I think she can open doors for me. That is a reality,” she told The Oregonian/OregonLive.Susheela JayapalNakamuraEnvironmental championJayapal earned her law degree from the University of Chicago and worked for two decades as a financial analyst and corporate lawyer before stepping away from paid work to raise her children. Since 2000, she has held volunteer leadership roles at Planned Parenthood Columbia Willamette, the Oregon Community Foundation and other nonprofits.During her nearly five years on the Multnomah County Commission, Jayapal said, her influence was limited by the powerful role of the commission’s chair, who has wide latitude to steer the board’s agenda. She casts herself as a pragmatist who worked behind-the-scenes to fill funding gaps and help steer the county through the pandemic and intertwined crises of homelessness, behavioral health and addiction.Jayapal said she was an early proponent of long-term rental assistance, which can prevent residents from becoming homeless, and battled to pass a modest pay raise for employees at nonprofits that provide much of the county’s services for unhoused residents. She was a vocal critic of the Zenith Energy fossil fuel storage site in Northwest Portland and the use of leaded gasoline at Portland International Raceway.Jayapal has “real policy bonafides” and doesn’t mince words when advocating for climate action, said Damon Motz-Storey, director of the Oregon chapter of the Sierra Club, which endorsed her.“Those are the things that we look for in a climate leader,” they said.If elected, Jayapal said she would work to ramp up federal investment in affordable housing and rental assistance, which is often unavailable to residents because of high demand. Along with a Green New Deal and the establishment of a single-payer health care system, she calls for legislation to prevent deforestation and leaks of methane, a greenhouse gas responsible for 30% of global temperature rise.Maxine Dexter, a doctor in her second term in the Oregon House, says she would use her clinical experience as well as her successes building relationships in the state Legislature to increase her odds of accomplishing policy wins in Congress.Dave Killen / The OregonianData-driven doctorGrowing up, Dexter attended public schools and worked a unionized job in a grocery store. She graduated from the University of Washington’s medical school.She has worked as a doctor for more than 20 years. In 2020, she was appointed to fill a vacancy in the state Legislature. Dexter said her family currently lives slightly outside of the 3rd District but plans to move back in.Dexter said she has effectively pursued evidence-driven solutions to health policy, affordable housing and homelessness, climate change and other complex issues.“We can solve these problems if we have experts in the room,” she told The Oregonian/OregonLive editorial board.Dexter criticizes the role of for-profit companies in health care and recently sponsored a failed bill that would have limited the influence of private equity companies in owning medical practices or centers. In 2021, Dexter helped pass a law that directed the state health agency to study the creation of a public health insurance option serving more low-income Oregonians. That plan has come to fruition and will roll out in July.As chair of the House housing committee, Dexter advanced “some of the biggest housing reforms and housing investment packages this state has ever seen,” said former House Speaker Dan Rayfield, D-Corvallis, who endorsed her.If elected to Congress, Dexter would aim to simplify what she called an overly complicated health care system. She said her “ultimate goal” is advancing a single-payer health care system without causing “chaos” in the process. Dexter said she would also work to expand a federal low-income housing tax credit and seek federal funding for detox beds.Eddy Morales, a Gresham City Council member who spent about a decade working on political causes in Washington, D.C., said tragedies that left three of his siblings dead motivate him to fight to revise past policy failures.Mark Graves/The OregonianD.C., Oregon experienceOn the campaign trail, Morales stresses his family’s lived experience with policy failures. His two brothers died in gun violence and his sister died from opioid and alcohol addiction, he says.“These are the things that have really motivated me for the last 25 years,” Morales said.He touts his longtime work as an organizer for progressive causes. He has served as president of the Gresham City Council. Morales founded East County Rising, a political committee that works to engage voters in east Multnomah County, call attention to their priorities and promote candidates of color and other progressive candidates for local offices.He also served as treasurer of the Democratic Party of Oregon, including during the time when the party falsely reported its largest ever contribution, $500,000, came from a Nevada cryptocurrency funds processor instead of an executive at now-disgraced cryptocurrency firm FTX. Although Morales was not copied on the string of emails in which party officials agreed not to name the true donor, a state lawyer wrote that Morales “did not perform the necessary due diligence to confirm the accuracy of the contributor.”The state party returned the funds once criminal wrongdoing by FTX executives including Sam Bankman-Fried came to public attention, Morales noted. “I am glad he and his cronies have been found guilty and sentenced,” Morales said.Morales got his start advocating for farm workers as a student at the University of Oregon. Beginning with a stint as president of the United States Student Association, Morales was based for about a dozen years in Washington, D.C., a perch from which he advocated for the Affordable Care Act on behalf of the nonprofit Center for Community Change. He also mobilized Latino voters in the South and Southwest for The Democracy Alliance.“Eddy has a skill or a personality to motivate people, to engage people,” said Gresham City Councilor Dina DiNucci, who has endorsed his bid for Congress. He is also adept at building political alliances, she said.In Gresham, Morales helped advance two affordable housing complexes largely funded by Metro housing bonds: the 225-unit Rockwood Village and the 180-unit Wynne Watts Commons, which is billed as the largest net-zero energy, affordable housing complex in the region.As a member of Congress, Morales said he would work to fund multi-generational affordable housing and update first time homeownership grants that he says are outdated. He would also advance offshore wind development and work toward a comprehensive overhaul of the U.S. immigration system that reunites separated families and safeguards the asylum-seeking process, he said.-- Grant Stringer is a freelance journalist in Portland; stringer.grantj@gmail.com; @Stringerjourno

A Solar Panel Standoff Threatens U.S. Climate Plans

Inexpensive Chinese solar panels are pitting Americans who want cheap equipment against those who want to make it

CLIMATEWIRE | A flood of Chinese solar components is casting a shadow on President Joe Biden's climate priorities.That's creating deep divisions in the U.S. solar industry and causing political headaches for the president. American manufacturers are calling for additional trade restrictions on Asian imports amid what they say are market-flooding practices by China that are undermining U.S. plans to build a fleet of solar factories.But those calls are colliding with the interests of some renewable energy developers that rely on China-linked companies for components that are fueling a solar building spree in the U.S. They contend new trade barriers could hinder U.S. efforts to eliminate climate pollution in the electricity sector — a pillar of Biden's environmental agenda.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.The solar standoff underscores Biden's precarious balancing act as he races toward the presidential election.The Inflation Reduction Act, the sweeping climate law signed by Biden in 2022, lavishes tax breaks on companies to build the solar supply chain in the United States. Slowing foreign imports could help create demand for domestic components. But it could also hurt Biden's other priority: achieving 100 percent carbon-free power by 2035 — a promise that analysts say can't be met without a full-speed buildout of renewable energy.That might not be possible without imported solar products.“There’s numerous examples of the conflict between President Biden’s decarbonization agenda and his deglobalization agenda,” said Tim Fox, an analyst who tracks the industry at ClearView Energy Partners. “You want to decarbonize with available and cheap solar panels. But you also want to develop solar here at home. There is tension between those two efforts."The situation came to a head this week when seven U.S. solar manufacturers filed petitions with the federal government requesting an investigation into whether the budding U.S. industry is being harmed by what they say are unfair trade practices from China-linked companies operating in Cambodia, Malaysia, Thailand and Vietnam.The manufacturers argued that companies in Southeast Asia are benefiting from foreign subsidies, and exporting below-cost solar components into the U.S. market. That should make them subject to higher tariffs, the manufacturers said.As a warning of what might come, they pointed to an announcement earlier this year by CubicPV, a Massachusetts-based solar manufacturer that scrapped plans for a massive factory after citing a “collapse” in prices and surging construction costs.“We're at a real inflection point now for developing clean energy manufacturing in the United States,” said Scott Paul, president of the Alliance for American Manufacturing. “The presence of the massive amount of industrial overcapacity China has in solar, in [electric vehicles] and related industries is a real threat, and we know this because we've seen this play out before in the United States and in other industries. It doesn't end well.”'Green trade war'The use of trade barriers has long been opposed by developers, who say higher prices driven by tariffs could slow U.S. solar growth and make it more expensive to address climate change.Kevin Hostetler, CEO of Array Technologies, a provider of utility-scale solar trackers, a technology that turns panels toward the sun, said the manufacturers’ trade petition creates “a level of uncertainty and delay” that negatively impacts the U.S. solar industry.“We just simply don't need the short-term shocks to the system that may benefit one or two particular companies, but then harm the broader industry over the course of what could be multiple years,” he said.A statement attributed to a White House spokesperson said the administration won’t weigh in on the petitions, but it pointed to “historic investments” in the solar industry under Biden. The administration is also monitoring potential unfair market practices by China in solar and other sectors.“As President Biden has made clear, his administration is keeping all tools on the table to support the unprecedented investments secured by the President’s agenda and take action to protect American workers and manufacturers against unfair competition,” the statements said, adding that Biden is committed to expanding solar deployment.The solar battle is part of a wider spat between the U.S. and China — that members of the Biden administration are increasingly acknowledging.As China’s domestic real estate market has cooled, the country has leaned heavily on its manufacturing sector to bolster economic growth. Wood Mackenzie, a consulting firm, estimated that Chinese firms make 80 percent of the components in a solar panel, such as polysilicon, wafers, cells and modules.At the same time, S&P Global Market Intelligence said an “unprecedented wave” of imported solar panels — linked largely to China-based companies operating in Southeast Asia — came into the U.S. in 2023. Cambodia, Malaysia, Thailand and Vietnam together accounted for 84 percent of U.S. solar panel imports in the fourth quarter of last year.In Europe, China’s dominance and the supply glut of cheap solar panels has already left manufacturers unable to compete. The surge in foreign panels has the potential to stymie a boom in U.S. solar manufacturing launched by the IRA.U.S. companies have announced plans to build factories capable of churning out 140 gigawatts of solar module capacity, Wood Mackenzie said. But only half of that is likely to be built by 2027, said Elissa Pierce, an analyst who tracks solar manufacturing at the consulting firm. Factories that build subcomponents that go into panels face even bigger hurdles. Of the 61 GW in announced wafer facilities, Wood Mackenzie said only 3.3 GW would be built. Less than one-quarter of the announced cell manufacturing facilities is actually expected to come online.“There is a growing transition from a traditional trade war to a green trade war,” said ClearView’s Fox.Biden administration officials have sharpened their rhetoric in recent weeks."It's important that China recognize the concerns [and] begin to act to address it," Treasury Secretary Janet Yellen said this week. "But we don't want our industry wiped out in the meantime, so I wouldn't want to take anything off the table."Yellen recently traveled to China to discuss the administration’s concerns.'No objective answer'A similar fight in 2022, over China funneling U.S.-bound products through Southeast Asia, left some manufacturers frustrated and prompted a presidential veto. This time could be different.“I can safely say I've never filed a trade case before where there were such strong statements of support in terms of the need to address Chinese dumping, in particular in the renewable energy sector, as we've had in recent weeks,” said Tim Brightbill, co-chair of Wiley Rein’s international trade practice and lead counsel in the manufacturers’ recent petitions.Those petitions, filed Wednesday, are backed by First Solar, Qcells, Meyer Burger, Mission Solar, REC Silicon, Convalt Energy and Swift Solar — many of which have announced new expansions or investments since passage of Democrats’ climate law.It comes on the heels of a request from Qcells, a South Korean solar maker that has invested $2.5 billion in new factories in Georgia, to end an exemption under an existing tariff regime on bifacial solar panels.The company said double-sided modules now compose over 98 percent of U.S. solar module imports — meaning less than 2 percent of imports are subject to duties. The administration is reportedly planning to soon grant that request.Brightbill called the IRA “a once-in-a-lifetime opportunity to reclaim the solar supply chain and the solar manufacturing process here in America.” But, he added, “you have to not just have the investment, you have to have enforcement as well.”But the petitions received an icy response from the industry’s largest trade groups.In a joint response Wednesday, the Solar Energy Industries Association, American Clean Power Association, Advanced Energy United and American Council on Renewable Energy expressed concern that the trade petitions “will lead to further market volatility across the U.S. solar and storage industry and create uncertainty at a time when we need effective solutions that support U.S. solar manufacturers.”The administration has also faced bipartisan pressure from lawmakers to take additional steps to support the domestic industry. That’s included calls to better incentivize purchases of U.S.-made solar components through stronger tax credits, and to further address stockpiling of Chinese-linked products.“China is running the same playbook Ohio steelworkers know all too well, routing their products through other southeast Asian countries to try to get around the rules,” Ohio Sen. Sherrod Brown, a Democrat who is facing a tough reelection race, said in a statement. “The Administration cannot let them get away with it.”The administration last year determined Chinese companies were funneling solar products through Southeast Asia in order to avoid tariffs. Then it did the opposite of what many manufacturers had hoped: It placed a two-year moratorium on new tariffs, after the initial inquiry prompted months of infighting within the solar industry.The moratorium ends in June, and duties on solar modules are expected to resume for companies that are circumventing tariffs. “We will enforce that rigorously — including ensuring that imported panels are not being inappropriately stockpiled,” a White House official told POLITICO, speaking anonymously to abide by administration guidelines.Antoine Vagneur-Jones, head of trade and supply chains at BloombergNEF, said the U.S. faces a choice. He pointed to Europe as an example of the stakes. Solar modules there are roughly half as expensive as those in the U.S., due to a lack of trade barriers. Yet European solar factories are closing, leaving the continent almost entirely dependent on China for solar equipment.Adopting tariffs could help expand factories in the U.S., creating jobs and political support for the industry, he said. But it will mean higher costs for solar panels as critics contend that cleaner energy sources is already too expensive.“Are you prioritizing speed? Are you prioritizing not being entirely reliant on one region? Those are value judgments,” Vagneur-Jones said. “There is no objective answer.”This story also appears in Energywire.Reprinted from E&E News with permission from POLITICO, LLC. Copyright 2024.

New species of jumping spider found on university campus in Cornwall

Exotic spiders flourish in Britain helped by the effects of global warming and international tradeSome are small and jumpy; others are large and intimidating – if you’re a humble housefly. Exotic spiders are flourishing in Britain as international trade offers ample opportunities for spider travel and global heating provides an increasingly hospitable climate.A jumping spider new to science has been identified living on the University of Exeter’s Penryn campus in Cornwall.

Some are small and jumpy; others are large and intimidating – if you’re a humble housefly. Exotic spiders are flourishing in Britain as international trade offers ample opportunities for spider travel and global heating provides an increasingly hospitable climate.A jumping spider new to science has been identified living on the University of Exeter’s Penryn campus in Cornwall. The nearest known relative of the 3-4mm-long Anasaitis milesae is found in the Caribbean, making it highly likely that this tiny species – alongside 17 other non-native jumping spider species – found its way to Britain from distant climes.Much larger and more noticeable new arrivals include Zoropsis spinimana, popularly known as the false wolf spider, a Mediterranean species that is thriving in houses across London, and the striking green-fanged tube web spider (Segestria florentina), which first got a foothold in Bristol and is now found across southern Britain.About 50 non-native spiders have been recorded in Britain among 3,500 non-native established species, most of which have been inadvertently introduced by the global movement of goods and people. Only about 10-15% of non-native species are considered to be “invasive” – such as grey squirrels, Japanese knotweed and the Asian or yellow-legged hornet – causing a negative environmental or human impact.Helen Smith, a conservation officer for the British Arachnological Society, said: “Britain’s spider fauna, along with the rest of our wildlife, is changing more rapidly than ever before. As new, exotic species spread, particularly beyond urban areas, the chances of them impacting on less common native species increase.“As well as competing for prey and for living spaces, these spiders may bring with them new parasites and diseases, an issue well known from invasive grey squirrels and crayfish but very poorly studied in spiders. Around 15% of our native spider species are already threatened with extinction as a result of habitat loss and climate change – in the future, non-native species could well add to the risks they face.”The new species of jumping spider was discovered by Tylan Berry, Devon and Cornwall area organiser for the British Arachnological Society, during a “bioblitz”, or biological census, on the Penryn campus. The unusual species was confirmed as new to science and named by Dmitri V Logunov, a jumping spider expert, of the Zoological Institute of the Russian Academy of Sciences.“It is amazing that something can be hiding in plain sight,” said Berry. “It’s established on the campus and easy to find in good numbers, living and breeding, and it’s also been found in another ornamental garden 30 miles away.“It’s a pretty little thing, and looks like a bit of old 1970s carpet – brown and white and patterned.”Cornwall and Devon are hotspots for new spiders, thanks to their ports and mild climate, with the absence of frosts in some areas allowing exotic species to survive the British winter.Berry has identified a large population of another non-native spider, the grey house spider (Badumna longinqua) in Plymouth.This large spider hails from New South Wales, Australia, and is considered one of the most invasive spider species in some countries where it has been accidentally introduced, including Japan, the US and Brazil.The fast-spreading species is not yet well-established on continental Europe but has rapidly moved through Britain since first being spotted in 2021. Since being found in Washington, north-east England, it’s been recorded in south Wales, Nottinghamshire and Camborne and Newquay in Cornwall. Many early sightings were close to ports or garden centres, suggesting they arrived on imported plants.“It’s incredibly well-established in Plymouth,” said Berry. “I was really taken aback. It’s spread over a 6km/sq area and in some places is the dominant species.”The spider lives in urban areas, residing in large aggregations and weaving webs that look similar to some native spiders on wooden fences and metal sign-posts, including bus stops.In places, Berry found only this species and few native spiders, and fears it may have supplanted native lace web spiders and missing sector orb weaver spiders.“It’s definitely got potential for causing a shift in the ecosystem,” said Berry. “But rather than predating on native spiders, I think they might just be competition for space.”Exotic spiders excite tabloid newspaper editors and alarm arachnophobes, and the false wolf spider and the green-fanged tube web spider have the potential to cause a stir because of their size and their ability, in theory, to pierce human skin with their (briefly painful but harmless) nips.In reality, despite media attention, the false wolf spider has caused little alarm and the green-fanged tube web spider keeps to itself, living in holes in walls and only darting out at night to seize its prey.Both species are on the move, with the false wolf spider having spread as far west as Somerset and as far north as Newcastle since it was first photographed in Britain in 2008 – given a lift in some cases not only on global shipping containers but inside campervans of holidaymakers returning from continental Europe.Spider experts have a message: don’t panic.“Look out for these things, record them if you can, but be interested in them as well,” said Berry. “The more you learn, the more you understand about a species, and that’s a good way of getting rid of any fears or misinformation.“These arrivals are just going to happen. There’s very little we can do to stop them. Tied in to the warming of the climate, different species can get a hold in particularly areas and change ecosystems quite quickly.”

How Temperate Forests Could Help Limit Climate Change

People understand how saving tropical forests is good for the planet, but temperate forests are equally indispensable in fighting climate change

How Temperate Forests Could Help Limit Climate ChangePeople understand how saving tropical forests is good for the planet, but temperate forests are equally indispensable in fighting climate changeBy Amanda Leland & Steven HamburgBlue Ridge Parkway, Great Smoky Mountains National Park, North Carolina. Itai MinovitzGetty ImagesMuch of the conservation and climate change spotlight falls on tropical forests. Given this, people might forget that forests in the temperate areas—those found in large parts of North America, Europe and higher latitudes in Asia and Australia—also have the power to help limit climate change. As much as preserving tropical rainforests is indispensable to climate progress, policy makers cannot ignore the critical role of temperate forests. This Earth Week, we must turn our attention—and dollars—to these swaths of trees, or face the loss of an important tool in managing global warming.Temperate forests represent about 25 percent of Earth’s arboreal lands. As temperatures have changed, temperate trees face threats from of harmful invasive pests from other regions, loss of forest lands from urban sprawl and farmland expansion, and catastrophic wildfires that are becoming more common and severe. At the same time, they are some of the most well-studied and well-understood ecosystems on Earth—giving us a chance to put science into action in the service of climate progress.To save temperate forests, we need to reduce land-clearing for housing and agriculture, then allow trees to regrow where they have been removed, and thoughtfully manage each acre to promote ecological health. To understand how reforestation and better management will aid in climate restoration, look to forest lands of the eastern U.S.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Between the time of European settlement and the early 20th century, at least 300 million acres of temperate forests in the U.S. were cleared for agriculture and timber—an area three times the size of California. This loss was especially concentrated in the East. But as agriculture moved to other parts of the country, abandoned farm fields throughout the region returned to forest largely through natural regeneration. Eastern forests continue to recover and are currently removing about 34 megatonnes of CO2 per year.But efforts to restore forests won’t matter if we don’t stop harmful pests like the emerald ash borer, hemlock woody adelgid and Asian longhorn beetle—hitchhikers to the U.S. from other parts of the world. Each of them is ravaging native tree species in the eastern US. Most invasive pests arrive on U.S. shores in container ships and airplanes; the federal government needs to do much more to inspect cargo and intercept pests at our ports of entry.But we believe the greatest emerging threat to temperate forests is catastrophic wildfire— wildfires that occur outside normal historic frequency and severity. Ironically, widespread fire suppression, especially in dry forests in the West, has allowed a build-up of dangerous fuel such as deadwood and dense regeneration. These fuels, combined with climate change-induced drought, have led to increasingly frequent and severe fires that kill enormous numbers of trees and spew what we calculate is up to 230 megatonnes of CO2 to the atmosphere in bad fires years in the United States.The effects of these sorts of fires have been most stark in the western U.S., Canada, and Australia, but they are also becoming more troublesome in southern Europe and Chile. The conundrum is that fire can be beneficial and restorative, but it has to be done right. We need to thin out understory trees and strategically apply prescribed fire and cultural burns—those led by Indigenous practitioners steeped in historic fire management practices. In some cases, it involves fire managers letting wildfire burn at lower intensity and when weather conditions allow—without heavy fire suppression tactics.These treatments also reduce stress on the remaining trees. They help combat large-scale insect damage, another phenomenon in western North American forests where, for example, bark beetles kill large numbers of trees. Recent investments through President Biden’s Inflation Reduction Act and Bipartisan Infrastructure Law provide an opportunity to demonstrate ecological thinning and beneficial fire at scale.We need to protect and better care for the few temperate forests that still contain stands of very old trees. These old forests are some of the most carbon-dense ecosystems, harbor unique biodiversity and offer distinctive opportunities for recreation and respite. As such, governments and landowners must make sure middle-aged forests that regrew after cutting are stewarded into the old-growth forests of tomorrow. President Biden has taken important steps in this direction as well, by instituting, for the first time, rules to protect and steward old-growth forests on federal lands across the U.S.Recent Environmental Defense Fund research shows that conserving and restoring temperate forests, alongside tropical forests, are among the most scientifically sound nature-based climate actions. The U.S. is taking important steps to capitalize on these opportunities, but more needs to be done. We need to take advantage of current public funding for forest conservation and stewardship and, at the same time, promote private investment to support restorative measures and sustainable forestry to capture the climate potential of temperate forests in the U.S. and elsewhere.This is an opinion and analysis article, and the views expressed by the author or authors are not necessarily those of Scientific American.
