How Mount Everest has been preserving people’s germs from coughs and sneezes

The study led by the University of Colorado Boulder found climbers are leaving behind microbes that could survive in harsh climates for decades or even centuries

Snowmageddon: How Arctic warming is causing extreme cold in the US

A study in the journal Science that combined observations and models showed that Arctic warming likely disturbed the polar vortex – a large area of low pressure and cold air surrounding Earth’s poles that weakens in summer and grows stronger in winter – yet again

Canadian polar bears near 'bear capital' continue to die at fast rate

Since the 1980s, the number of bears in the region has fallen by nearly 50 per cent, the authors found. The ice essential to their survival is disappearing

The Arctic is getting wetter: How shifting seasons will affect the wildlife and ecosystem

Arctic precipitation is increasing throughout the year, and the seasons are shifting. Much of the new precipitation is now falling as rain, sometimes during the winter, disrupting daily life for humans, wildlife, and plants

The melting Arctic ice is releasing ancient germs: Should we be worried?

The thawing permafrost is releasing organic matter that has been frozen for millennia, including bacteria and viruses. One concern is that the melting ice could release the bodies of long-dead people who might have died of an infectious disease and so release that into the world

Why increased rainfall in the Arctic is bad news not only for polar region but the whole world

The Arctic water cycle is expected to shift from a snow-dominated one towards a rain-dominated one during the 21st century, although the timing of this is uncertain.

In the Arctic's, global warming is happening three times faster than in the rest of the world

Permafrost -- defined as soil that stays frozen year-round for at least two consecutive years -- lies under about a quarter of the land in the Northern Hemisphere.

Temperature rise in Greenland causes ice sheets to melt at twice the average rate

There was enough of melted water "to cover Florida with two inches (five cm) of water".

Explained: How Antarctica hit record temperature amid heat wave in Europe, Arctic

The new record for the maximum temperature for Antarctica is now 18.3 degrees Celsius, eclipsing the previous high of 17.5 degrees Celsius in March 2015

Arctic's 'Last Ice Area' surprises scientists, shows early signs of melting

While most of the Arctic could be free of ice in the summer by mid-century, they thought the Last Ice Area won’t be ice-free until 2100.
