Will overshooting 1.5°C of warming push us over climate tipping points, triggering irreversible and abrupt changes?

Scientists have found that Greenland’s bedrock is rich with mercury in some areas — and as the ice sheet rapidly melts, that mercury is being released into local waters.

The discovery of fossil plants below a mile of Greenland ice indicates that the ice sheet completely melted in the past, and suggests it could rapidly do so again.

Using radar and other techniques, researchers have mapped out the sediments left by a lake that apparently existed before Greenland was glaciated. Next step: drilling through the ice to see what they contain.

To measure algal blooms across large regions of the Greenland ice, and understand their effects on melting over time, scientists are turning to space.

If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century since shortly after the end of the last ice age, a new study concludes.

The massive ice sheet is now locked into a certain amount of decline. But reducing emissions remains critical to preventing catastrophic loss of the entire ice sheet.

An international team of polar researchers says that the Greenland ice sheet experienced record loss in 2019.

In a new study, researchers propose a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of meltwater.

Study identifies unprecedented atmospheric conditions behind devastating summer; suggests climate models may greatly underestimate future melting.
