Federal report boosts plan to remove 4 dams on Calif river

9/19/2022

 
Federal regulators on Friday issued a final environmental impact statement that supports the demolition of four massive dams on Northern California’s Klamath River to save imperiled migratory salmon. The staff's recommendation, which largely echoes an earlier draft opinion, tees up a vote on the roughly $500 million project by the five-member Federal Energy Regulatory Commission later this year. The removal of the four hydroelectric dams on the lower Klamath River — one in southern Oregon and three in California — would be the largest dam demolition project in U.S. history. - ABC News

How Americans’ love of beef is helping destroy the Amazon rainforest

5/1/2022

 
"Cattle ranching, responsible for the great majority of deforestation in the Amazon, is pushing the forest to the edge of what scientists warn could be a vast and irreversible dieback that claims much of the biome. Despite agreement that change is necessary to avert disaster, despite attempts at reform, despite the resources of Brazil’s federal government and powerful beef companies, the destruction continues. But the ongoing failure to protect the world’s largest rainforest from rapacious cattle ranching is no longer Brazil’s alone, a Washington Post investigation shows. It is now shared by the United States — and the American consumer. - Washington Post (Original)

A new tundra, engineered by beavers

2/18/2022

 
Beavers, once seldom seen in northwest Alaska, started appearing more frequently in the ’80s and ’90s. Pastor Lance Kramer (Inupiaq) traps beavers today, mostly for making fur hats. He recently asked an elder about the area’s first sightings. “They saw this thing on the tundra, and it looked like a wolverine, but it was a really long beaver,” Kramer said. “(It) had walked so far on the tundra to get up this way that it wore out the bottom of its tail.”  Now the animals — and their ponds, dams and lodges — are everywhere. Using satellite images of the Kotzebue area, scientists found that the number of beaver dams surged from two in 2002 to 98 in 2019, a 5,000% jump. And it’s not just Kotzebue: Beaver ponds doubled regionally since 2000, with 12,000 in northwestern Alaska now. Beavers, dubbed “ecosystem engineers” because of how they flood their surroundings, are transforming the tundra. - HCN

Some Farm Animals Might Have a Sense About Impending Earthquakes

Stabled animals seem to grow fidgety in the hours before an earthquake, whereas their free-range counterparts show no discernible difference in behavior. - EOS
