America’s Sickest Wetlands Are in the West, EPA Finds

An exhaustive assessment released by the EPA this month based on more than 1,000 wetland surveys conducted in 2011 concluded that while nearly half of the remaining wetlands in the Lower 48 are in “good” condition, just one-fifth of the wetlands in the West are doing so well. The findings portend problems nationwide as seas rise, with planners… Read More

Global Warming Threatens the World’s Special Places

The most precious places on the planet are under siege by climate change. From Venice being slowly consumed by the sea to rising temperatures stressing out Uganda’s famous gorillas, history and the natural world are facing a threat unlike anything they’ve ever experienced before.

Abrupt Atlantic Ocean Changes May Have Been Natural

Abrupt Atlantic Ocean Changes May Have Been Natural

Climate change may not have been to blame for an abrupt recent slowdown of a sweeping Atlantic Ocean current, a change that delivered an intense pulse of ocean warming and sea level rise through the Gulf of Maine and elsewhere along the East Coast. Modeling-based analysis by British scientists, published Monday in Nature Geoscience, concluded that … Read More

Global Warming Will Hit Poorer Countries Hardest

Global Warming Will Hit Poorer Countries Hardest

New evidence that poorer countries will suffer the worst effects of climate change has shown that the number of hot days in tropical developing countries is likely to increase markedly as global warming takes hold. It has long been expected that poor people would bear the brunt of climate change, largely because so many more of the world’s poorest … Read More

Sea Level Rise Could Help Marshes Ease Flooding

Sea Level Rise Could Help Marshes Ease Flooding

Along the mid-Atlantic coast, where waters are rising quickly, marshes are on the march, consuming forestland, farms and yards. “Habitats are changing fast here,” said Matt Whitbeck, a biologist at the Blackwater National Wildlife Refuge in Maryland, where dead trees still jut from young marshes. Newly published modeling shows that a looming… Read More

Coral Deaths Threaten Coasts With Erosion, Flooding

Coral Deaths Threaten Coasts With Erosion, Flooding

Colorful corals draw snorkeling tourists to natural marine playlands along the Florida Keys, Mexican Riviera Maya and northeastern Australia, and new research shows the flailing ecosystems they underpin also protect beachfront hotels from erosion and floods.

Diplomats and leaders representing more than half the world’s countries on Friday gave a global effort to slow climate change a ceremonial nudge forward. The signing in New York of the Paris Agreement, which is a United Nations climate treaty that was finalized during high-profile negotiations in France in December, was a symbolic overture to year … Read More

Fate of World’s Coastlines Rests on Melting Antarctic Ice

Fate of World’s Coastlines Rests on Melting Antarctic Ice

Mayors from small towns, planners from the world’s largest cities and U.N. diplomats are being guided on the details of a looming coastal crisis by sea level projections compiled by a U.N. science panel. The panel’s work includes warnings about the amount of flooding that could be caused by melting in Antarctica, and those warnings have been… Read More
