When the oceans became acidic

When the oceans became acidic

Colossal volcanic eruptions some 250 million years ago have long been linked to the widespread global extinction known as the “Great Dying“, a 60,000-year period that saw 90 percent of all sea creatures and more than two-thirds of all plants and animals on land die off. But new research has for the first time identified the specific cause of the […]

Megadrought may grip the Southwest

Megadrought

The Southwest and central Great Plains are likely to be hit in coming decades by the most prolonged megadrought in more than 1,000 years, a new climate study predicts. Scientists from NASA, Columbia University, and Cornell University created a long-term climate model after analyzing historical temperature records, carbon dioxide emissions, and drought trends from tree rings.The record shows that the […]

How Supervolcanoes Erupt

  Luckily for most of the U.S., the likelihood this eruption would happen is pretty low: about one in 100,000 any given year. If it did happen, it would be pretty devastating, though. “Thinking about a Yellowstone super eruption is like imagining a large asteroid hitting the Earth,” says Jacob Lowenstern, a research geologist with the USGS and Scientist-in-Charge of […]

Neanderthals—the other white meat

Neanderthals, a sturdy hominid species closely related to Homo sapiens, lived in Europe for about 270,000 years until humans arrived on the continent, about 30,000 years ago, at which point they quickly disappeared. The latest theory for their puzzling extinction is that humans exterminated, and maybe even ate, their Neanderthal cousins. French anthropologist Fernando that the bacterial disease was present […]

Antarctic Ice Sheet Mass gains greater than losses

Antarctic Ice Sheet

A new NASA study on the Antarctic Ice Sheet says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that […]
