Great apes began to diverge from other primates about 25 million years ago, according to eastern African fossil records. Though it would take another 20 million or so years for upright-walking hominins to appear, understanding the...
As climate change accelerates and politicians continue to argue, scientists are exploring radical new ways to protect our planet. One of the most ambitious concepts under development is a Planetary Sunshade System (PSS), essentially a massive...

Cracks in Greenland Ice Sheet grow more rapidly in response to climate change, study warns

The Greenland Ice Sheet is cracking open more rapidly as it responds to climate change. The warning comes in a new large-scale study of...

ESA and NASA satellites deliver first joint picture of Greenland Ice Sheet melting

Academics from Northumbria University are part of an international research team which has used data from satellites to track changes in the thickness of...

Drilling campaign reaches a depth of 808 meters in the Antarctic ice sheet

In Antarctica, the second drilling campaign of the Beyond EPICA—Oldest Ice project, at the remote field site Little Dome C, has been successfully completed....

Runaway W. Antarctic ice sheet collapse not ‘inevitable’: study

The runaway collapse of the West Antarctic Ice Sheet—which would trigger catastrophic sea level rise—is not "inevitable", scientists said Monday following research that tracked...

Ancient ice age valleys offer clues to future ice sheet change

Deep valleys buried under the seafloor of the North Sea record how the ancient ice sheets that used to cover the UK and Europe...

Record of Antarctic ice sheet response to climate cycles found in rock samples

By analyzing unusual rock samples collected years ago in Antarctica, scientists at the University of California, Santa Cruz, have discovered a remarkable record of...

World’s biggest ice sheet could cause massive sea rise without action

The world's biggest ice sheet could cause "several meters" of sea-level rise over centuries if the global temperature rises more than 2°C, according to...

Newly discovered lake may hold secret to Antarctic ice sheet’s rise and fall

Scientists investigating the underside of the world's largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might contain a history...

Scientists discover a vast, salty groundwater system under the Antarctica ice sheet

A new discovery deep beneath one of Antarctica's rivers of ice could change scientists' understanding of how the ice flows, with important implications for...
