The National Science Foundation (NSF) has concluded that rising temperatures will lead to a massive "greening" of the Arctic by mid-century, as a result of marked increases in plant cover.
Giant camels once roamed Canada's High Arctic - much further north than previously believed - and may have evolved their flat feet and humps as a result.
The widespread decline in Arctic sea ice is causing big changes to the balance of greenhouse gases in the atmosphere, say researchers from Sweden's Lund University.
Solar geoengineering can be safely tailored to manage specific risks like the loss of Arctic sea ice, says a group of researchers keen to persuade the world that such techniques aren't necessarily a disaster waiting to happen.
The blanket of sea ice floating atop the Arctic Ocean has melted to its lowest extent ever recorded - since satellites began measuring it in 1979, to be exact.
Melting sea ice and global atmospheric warming are making the Arctic warm as much as four times faster than the global average, Australian scientists say.
Arctic sea ice has reached its second-lowest level since satellite observations began over 30 years ago, scierntists at the University of Colorado Boulder's National Snow and Ice Data Center say.
