Atomic-resolution imaging shows why ice is so slippery

A team of physicists affiliated with several institutions in China has uncovered the reason behind the slipperiness of ice. In their study, published in the journal Nature, the group used atomic force microscopy to get a ...

No good news here: Key IPCC findings on climate change

The UN Intergovernmental Panel on Climate Change's first major scientific assessment since 2014, released Monday, shows unequivocally that global warming is unfolding more quickly than feared and that humanity is almost entirely ...

Study helps explain sea ice differences at Earth's poles

Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern ...

Melting Antarctic could impact oceans 'for centuries'

Rapidly melting Antarctic ice threatens to dramatically slow deep-water currents in the world's oceans, scientists say, impacting the spread of fresh water, oxygen and life-sustaining nutrients for centuries.

Declining sea ice to lead to cloudier Arctic: study

Arctic sea ice has been declining over the past several decades as global climate has warmed. In fact, sea ice has declined more quickly than many models predicted, indicating that climate models may not be correctly representing ...

Can a new type of glacier on Mars aid future astronauts?

On April 21, 1908, near Earth's North Pole, the Arctic explorer Frederick Albert Cook scrawled in his diary a memorable phrase: "We were the only pulsating creatures in a dead world of ice." These words may soon take on new ...

Arctic Ocean could be source of greenhouse gas: study

(Phys.org) -- The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine ...
