Ice loss due to climate change has slightly slowed the Earth’s spin, a new study shows — and it could affect how we measure time. Global warming has slightly slowed Earth's rotation — and it ...
Climate change is altering the Earth to its literal core, new research suggests. As polar and glacial ice melts because of global warming, water that was once concentrated at the top and the ...

The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick and over 3 km (1.9 mi) thick at its maximum. [ 57 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N ...
In the 1950s, early climatologists such as Syukuro Manabe have already been making attempts to describe the role of ice cover in Earth's energy budget. [11] In 1969, both USSR's Mikhail Ivanovich Budyko and the United States' William D. Sellers have published papers presenting some of the first energy-balance climate models to demonstrate that the reflectivity of ice had a substantial impact ...
Younger ice (first-year ice) is shown in darker shades, while older ice (four-year or older) is shown in white. This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The ...

Feedbacks associated with sea ice and snow cover are widely cited as one of the principal causes of terrestrial polar amplification. [12] [13] [14] These feedbacks are particularly noted in local polar amplification, [15] although recent work has shown that the lapse rate feedback is likely equally important to the ice-albedo feedback for Arctic amplification.
