Extreme climatic events increasingly threaten emperors
Emperor penguins are under increasing pressure and could be virtually extinct by 2100 due to clustered extreme events.
“Atlantification” causes ice caps in Russian Arctic to melt faster
Warming is rapidly advancing in the Russian Arctic as well. The melting of glaciers and ice caps on high Arctic archipelagos is driven primarily by warm Atlantic waters.
Record temperatures and massive ice melt in Greenland
Temperatures in Greenland were twice as high as normal last week and the ice sheet lost more than 8 billion tons of ice in a single day.
Permafrost network as an opportunity for Arctic security policy
A data network could both provide solutions to permafrost loss and improve communication between rival Arctic nations.
Arctic ocean could be ice-free in summer by 2030
The duration of the ice season will be shorter due to later freezing and earlier ice opening. This is reported by Vladimir Ivanov, expert of the Lomonossov Moscow University.
Arctic ice loss linked to monsoon in India
In a study, Indian scientists have found that the decline of sea ice in the Arctic may be causing extreme rainfall in India.
Northern hemisphere heatwaves more likely due to climate change
Heatwaves in the northern hemisphere are likely to become more frequent in the future, with corresponding consequences for living organisms and the landscape.
