'Watermelon snow' could be climate change omen

"Watermelon snow," so named for the deceptively delicate rosy tint appearing in the Italian Alps, could in reality be a climate change portent - although at least one scientist has warned against assuming a direct cause-and-effect relationship.

Arctic explorers find unusually thin ice as a result of climate change

The biggest ever science expedition to the Arctic encountered extremely thin sea ice, which could threaten future efforts to study the region.


Historic Arctic heat wave roasts Siberia

Wildfires are spreading. The mosquitoes are ravenous. People are shielding their windows from the midnight sun with foil and blankets.

Italian team covers glacier with giant white sheets to slow melting

A vast tarpaulin unravels, gathering speed as it bounces down the glacier over glinting snow. Summer is here and the alpine ice is being protected from global warming.


The iciest waters around Antarctica are less icy

An unusual combination of events caused the Weddell Sea to lose more sea ice than in recent years.

As ice melts, emperor penguins march toward extinction

The flightless birds depend on Antarctica’s frozen sea ice shelves for safety and breeding. But as temperatures rise, the shelves are vanishing.

12th-century lead pollution visible in Alpine ice

Lead pollution produced by 12th-century mines in Britain can be seen in Alpine ice cores, new research reports – directly mirroring historical records and demonstrating the impact of political events of the time.

Arctic 'shorefast' sea ice used by residents for hunting and fishing will be reduced by global heating

Climate change could significantly reduce 'shorefast ice' – the sea ice that forms along shorelines – across Northern Canada and Western Greenland. It is a vital resource that connects isolated communities and provides access to hunting and fishing grounds.


Climate change and melted ice reveal lost Viking mountain pass

Since 2011, a mountain pass in central Norway has seen unusually warm summers linked to climate change. The melt has revealed an unexpected treasure trove of more than 1,000 remarkably preserved artifacts.


Antarctica and Greenland are losing thousands of gigatons of ice - that's a lot

As the climate has warmed, Antarctica and Greenland have lost enough ice in the last 16 years to fill Lake Michigan, according to results from a new NASA mission.


Climate crisis: North pole 'soon to be ice free in summer', scientists say

Amid rapid global warming – with average Arctic temperatures already 2C above what they were in the pre-industrial era – the extent of the sea ice is diminishing ever faster.


Greenland is melting faster than we thought in 'one of the worst years on record'

Current climate simulations don't factor in changing atmospheric circulations, leading to the suspicion that the Greenland ice sheet will melt much faster than is currently predicted.
