30 years of heating up to 10℃ "New Arctic" is taking shape

Longyearbyen, Norway, is located on the Svalbard archipelago, in the lower reaches of the Longyearbyen Valley.

Once, the glacier coverage rate here was as high as about 60%, and the island had snow-capped mountains and endless fjords

The temperature is soaring, and the sea ice is decreasing

The Arctic climate is very different from the past

In fact, in some respects, the Arctic climate has undergone unprecedented changes

By the end of this century, if global temperatures continue to rise uncontrollably, other key elements of the Arctic climate, including temperature and precipitation, may also be very different from what was “normal” during the 20th century

Researchers Laura Landrum and Malika Holland of the National Center for Atmospheric Research in Colorado recently published their joint research results in the journal Nature Climate Change

Landrum told a reporter from the U.

Landrum and Holland will focus their future research on a very severe hypothetical climate situation

Sea ice decreases, "new Arctic" emerges

According to a report from the Geological Survey of Denmark and Greenland on the 14th, on the vast and ancient ice shelf on Greenland, a huge ice sheet covering an area of ​​113 square kilometers finally slipped into the sea last month

Researchers such as Landrum and Holland specifically investigated the changes in the area of ​​sea ice, temperature and precipitation patterns in the Arctic Ocean

Over time, the reduction in sea ice will only get worse

It is understood that sea ice will have a profound effect on the temperature of the Arctic

The research results of sea ice reduction confirm that a new Arctic has emerged

The change of sea ice is a clear sign, which shows that climate change is not a future problem, it has greatly reshaped the earth today

Climate change is "in progress"

The "New Arctic" will become warmer, more rainy, and less icy

In addition, the planning of human response to disasters may become increasingly difficult

Although this study provides a depressing picture of the future of the global climate, it is not inevitable
.
Other studies have shown that if countries around the world significantly reduce greenhouse gas emissions in the next few decades, they may slow down or prevent certain climate changes
.

Humans need to take immediate action
.
"For those living in the Arctic, whether it is humans, animals or plants, climate change is not the future
.
" Landrum said, "This is what is happening at the moment
