The dramatic melting of Arctic ice
is already driving extreme weather that affects hundreds of millions of
people across North America, Europe and Asia, leading climate
scientists have told the Guardian.
Severe “snowmageddon” winters are now strongly linked to soaring
polar temperatures, say researchers, with deadly summer heatwaves and
torrential floods also probably linked. The scientists now fear the Arctic
meltdown has kickstarted abrupt changes in the planet’s swirling
atmosphere, bringing extreme weather in heavily populated areas to the
boil.
The northern ice cap has been shrinking since the 1970s, with global
warming driving the loss of about three-quarters of its volume so far.
But the recent heat in the Arctic has shocked scientists, with temperatures 33C above average in parts of the Russian Arctic and 20C higher in some other places.
In November, ice levels hit a record low,
and we are now in “uncharted territory”, said Prof Jennifer Francis, an
Arctic climate expert at Rutgers University in the US, who first became
interested in the region when she sailed through it on a
round-the-world trip in the 1980s.
“These rapid changes in the Arctic are affecting weather patterns
where you live right now,” she said. “In the past you have had natural
variations like El NiƱo, but they have never happened before in
combination with this very warm Arctic, so it is a whole new ball game.
