Storing carbon in the Arctic
For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980.
Ex-NASA expert issues call for climate solutions
Longtime NASA expert James Hansen has issued a call for new approaches to stop global warming, saying solutions are needed and that currently accepted targets are too dangerous.
Greenland's shrunken ice sheet: We've been here before
Think Greenland's ice sheet is small today? It was smaller—as small as it has ever been in recent history—from 3-5,000 years ago, according to scientists who studied the ice sheet's history using a new ...
Underwater 'tree rings': Calcite crusts of arctic algae record 650 years of sea ice change
Almost 650 years of annual change in sea-ice cover can been seen in the calcite crust growth layers of seafloor algae, says a new study from the University of Toronto Mississauga (UTM).
'Missing heat' discovery prompts new estimate of global warming
An interdisciplinary team of researchers say they have found 'missing heat' in the climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade.
2013 marked by 'record sea level, weather extremes'
Sea levels this year posted a record high, making low-lying coastal populations ever more vulnerable to extreme weather like super-storm Haiyan, the UN said Wednesday.
