Trees have died in Rocky Mountain National Park, Colo., as climate change has intensified bark beetle infestations and drought. Patrick Gonzalez, CC BY-ND By Patrick Gonzalez, University of California, Berkeley Human-caused climate change is disrupting ecosystems and people’s lives around the world. It is melting glaciers, increasing wildfires, and shifting vegetation across vast landscapes. These impacts have reached national parks around the world and in the United States. Until now, however, no analysis had examined climate change trends across all…

Scientists fear that insects upon which humans depend are declining

Scientists fear that insects upon which humans depend are declining

The Associated Press reports: A staple of summer — swarms of bugs — seems to be a thing of the past. And that’s got scientists worried. Pesky mosquitoes, disease-carrying ticks, crop-munching aphids and cockroaches are doing just fine. But the more beneficial flying insects of summer — native bees, moths, butterflies, ladybugs, lovebugs, mayflies and fireflies — appear to be less abundant. Scientists think something is amiss, but they can’t be certain: In the past, they didn’t systematically count the…

Why do we love bees but hate wasps?

Why do we love bees but hate wasps?

Comments 0 Comment

University College London: A lack of understanding of the important role of wasps in the ecosystem and economy is a fundamental reason why they are universally despised whereas bees are much loved, according to UCL-led research. Both bees and wasps are two of humanity’s most ecologically and economically important organisms. They both pollinate our flowers and crops, but wasps also regulate populations of crop pests and insects that carry human diseases. “It’s clear we have a very different emotional connection…

The Guardian reports: Spix’s macaw, a brilliant blue species of Brazilian parrot that starred in the children’s animation Rio, has become extinct this century, according to a new assessment of endangered birds. The macaw is one of eight species, including the poo-uli, the Pernambuco pygmy-owl and the cryptic treehunter, that can be added to the growing list of confirmed or highly likely extinctions, according to a new statistical analysis by BirdLife International. Historically, most bird extinctions have been small-island species…

Ed Yong writes: In the 1800s, there were so many bighorn sheep in Wyoming that when one trapper passed through Jackson Hole, he described “over a thousand sheep in the cliffs above our campsite.” No such sights exist today. The bighorns slowly fell to hunters’ rifles, and to diseases spread from domestic sheep. Most herds were wiped out, and by 1900, a species that once numbered in the millions stood instead in the low thousands. In the 1940s, the Wyoming…

CBS News reports: Hurricane Maria killed far more people in Puerto Rico than initially thought, accounting for an estimated 2,975 deaths on the island from September 2017 through February 2018, according to a new analysis. The study found that those in low-income areas, and elderly men, were at greatest risk of dying. The independent analysis was commissioned by the governor of Puerto Rico and conducted by researchers at George Washington University’s Milken Institute School of Public Health. CBS News obtained…

Air pollution causes ‘huge’ reduction in intelligence, study reveals

Comments 0 Comment

The Guardian reports: Air pollution causes a “huge” reduction in intelligence, according to new research, indicating that the damage to society of toxic air is far deeper than the well-known impacts on physical health. The research was conducted in China but is relevant across the world, with 95% of the global population breathing unsafe air. It found that high pollution levels led to significant drops in test scores in language and arithmetic, with the average impact equivalent to having lost…

By Rhett A. Butler Despite ongoing deforestation, fires, drought-induced die-offs, and insect outbreaks, the world’s tree cover actually increased by 2.24 million square kilometers — an area the size of Texas and Alaska combined — over the past 35 years, finds a paper published in the journal Nature. But the research also confirms large-scale loss of the planet’s most biodiverse ecosystems, especially tropical forests. The study, led by Xiao-Peng Song and Matthew Hansen of the University of Maryland, is based…

EPA unveils new coal pollution rules. In the fine print: more deaths

The New York Times reports: The Trump administration has hailed its overhaul of federal pollution restrictions on coal-burning power plants as creating new jobs, eliminating burdensome government regulations and ending what President Trump has long described as a “war on coal.” The administration’s own analysis, however, revealed on Tuesday that the new rules could also lead to as many as 1,400 premature deaths annually by 2030 from an increase in the extremely fine particulate matter that is linked to heart…

PsyPost reports: An analysis of 108 Old World countries found that cold/wet climates suitable for dairy farming were associated with lactose tolerance in the year 1500, which was in turn associated with higher child survival rates, greater per capita income, and fewer children per family in the year 1800. This enhanced production power was in turn associated with political freedom and civil liberties in the year 2000. The researchers believe that lactose tolerance led to longer life expectancy and postponed…

The New York Times reports: As a corporate lawyer, William L. Wehrum worked for the better part of a decade to weaken air pollution rules by fighting the Environmental Protection Agency in court on behalf of chemical manufacturers, refineries, oil drillers and coal-burning power plants. Now, Mr. Wehrum is about to deliver one of the biggest victories yet for his industry clients — this time from inside the Trump administration as the government’s top air pollution official. On Tuesday, President…

Science News reports: Freshwater is crucial for drinking, washing, growing food, producing energy and just about every other aspect of modern life. Yet more than 2 billion of Earth’s 7.6 billion inhabitants lack clean drinking water at home, available on demand. A major United Nations report, released in June, shows that the world is not on track to meet a U.N. goal: to bring safe water and sanitation to everyone by 2030. And by 2050, half the world’s population may…

William Finnegan writes: On the northwestern edge of Los Angeles, where I grew up, the wildfires came in late summer. We lived in a new subdivision, and behind our house were the hills, golden and parched. We would hose down the wood-shingled roof as fire crews bivouacked in our street. Our neighborhood never burned, but others did. In the Bel Air fire of 1961, nearly five hundred homes burned, including those of Burt Lancaster and Zsa Zsa Gabor. We were…

The Washington Post reports: Bayer’s stock slumped more than 10 percent in trading Monday, three days after a California jury awarded $289 million to a former groundskeeper who said the popular weedkiller Roundup gave him terminal cancer. The stock drop sent a cautionary signal to the company that acquired Monsanto, the maker of the weedkiller, in June for $63 billion. The merger created the world’s largest seed and agrochemical company, marrying Monsanto’s dominance in genetically modified crops with Bayer’s pesticide…

Bloomberg reports: The Trump administration wants to try to limit California’s special ability to require increasing purchase of electric vehicles in the state—but major automakers say they have no intention of reversing course on their electric vehicle plans. The Environmental Protection Agency and the Transportation Department are targeting California’s authority under the Clean Air Act to set stricter tailpipe emissions limits and zero emission vehicle requirements than the federal government. The agencies, as part of a larger Aug. 2 proposal…

Trump administration unveils its plan to relax car pollution rules

Comments 0 Comment

The New York Times reports: The Trump administration on Thursday put forth its long-awaited proposal to freeze antipollution and fuel-efficiency standards for cars, significantly weakening one of President Barack Obama’s signature policies to combat global warming. The proposed new rules would also challenge the right of states, California in particular, to set their own, more stringent tailpipe pollution standards. That would set the stage for a legal clash that could ultimately split the nation’s auto market in two. The administration’s…
