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. As coral reefs the world over bleach from warming waters, dissolve from acidification and … Read More

With The Paris Agreement Signed, Hard Work Begins

With The Paris Agreement Signed, Hard Work Begins

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

Sinking Atlantic Coastline Meets Rapidly Rising Seas

Sinking Atlantic Coastline Meets Rapidly Rising Seas

Geological changes along the East Coast are causing land to sink along the seaboard. That’s exacerbating the flood-inducing effects of sea level rise, which has been occurring faster in the western Atlantic Ocean than elsewhere in recent years. New research using GPS and prehistoric data has shown that nearly the entire coast is affected, from… Read More

Greenland’s Melt Season Started Nearly Two Months Early

Greenland’s Melt Season Started Nearly Two Months Early

To say the 2016 Greenland melt season is off to the races is an understatement. Warm, wet conditions rapidly kicked off the melt season this weekend, more than a month-and-a-half ahead of schedule. It has easily set a record for earliest melt season onset, and marks the first time it’s begun in April. Little to no melt through winter is the norm … Read More
