Greenland Sediment Sheds Light on Sea Level Rise

Greenland Sediment Sheds Light on Sea Level Rise

Greenland’s ice sheet is scraping rock bottom. No, it’s not hard up and in need of a loan. As ice moves from the center of the island to the sea, it’s scraping bedrock and transporting clues about just how fast the ice sheet is melting from the bottom up and what that means for sea level rise. The planet’s largest island is mostly covered in ice up… Read More

Hints of Climate Change in California’s Drought

Hints of Climate Change in California’s Drought

The pressure that’s on drought-hit Californians to conserve dwindling water supplies is largely the result of a stubborn ridge of high pressure that has been parking itself off their coastline. That ridge has blocked water-laden winter storms, sending them spiraling northward instead of into the Golden State, reducing snowpacks that Californians us… Read More

Science Shows How Climate Change is Baking Australia

As smoke billows from unnervingly early-season wildfires charring the Australian state of Tasmania, yet more dust is settling on the scientific discussion over how climate change contributed to last year’s deadly Australian heat. Last year was Australia’s hottest on record. And each of a set of five research papers published Monday in a special ed… Read More

Drought Takes Hold as Amazon’s ‘Flying Rivers’ Dry Up

Drought Takes Hold as Amazon’s ‘Flying Rivers’ Dry Up

The unprecedented drought now affecting São Paulo, South America’s giant metropolis, is believed to be caused by the absence of the “flying rivers” − the vapor clouds from the Amazon that normally bring rain to the center and south of Brazil. Some Brazilian scientists say the absence of rain that has dried up rivers and reservoirs in central and so… Read More
