Across the world, bats are in trouble from climate change – not only through collisions with the wind turbines that are intended to mitigate its effects, but from what the increasing warmth does to their ability to find their prey. Bats often get a bad press, portrayed as disease-spreading bloodsuckers. In fact, they perform a vital role as pollinators, seed […]

The last study showed that the world has about 3 trillion trees. That is over the estimate of 400 billion in previous studies. Researchers did a count by actually going out and physically counting trees, using satellite imagery, ground survey, and national forest inventories. Even though we have lost trees from fires, drought, and insect outbreaks there are still more […]

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University […]

The warming of the world’s oceans is penetrating radar. They discovered two causing a glacier the size of California in massive undersea valleys beneath the East Antarctica to melt, and scientists fear ice sheet, one of which is 3 miles wide, its collapse could eventually cause global Those canyons allow warm, salty water sea levels to rise by as much […]

Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of Arctic soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil. Soil in the Arctic has for thousands of years gathered large quantities […]

It’s official: There really was a giant, flightless bird with a head the size of a horse’s wandering about in the winter twilight of the high Arctic some 53 million years ago. The confirmation comes from a new study by researchers from the Chinese Academy of Sciences in Beijing and the University of Colorado Boulder that describes the first and […]

America’s earthquake epicenter was once California. Now it’s Oklahoma. In 2014 there were nearly 300 times as many magnitude 3.0 and greater earthquakes as there were in 2008—and more quakes of that magnitude than in the prior 30 years combined. The cause? Scientists can’t say definitively, but new research funded by the U.S. Geological Survey notes that as quakes increased […]

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 […]
