The most quickly changing state in the U.S. has no sea ice within some 150 miles of its shores, according to high-resolution sea ice synthesis from the National Weather Service. The big picture is clear, After an Arctic summer with well above-normal temperatures, Climate Changes, warmer seas, and a historic July heatwave, sea ice has nonexistent in Alaskan waters.
In the constantly warming Arctic, sea ice has totally melted around the Alaskan coast before, During 2017’s melt season, but never this early. “It’s cleared earlier than it has in any other year,” said Thoman. (Sea ice starts growing again in the fall when temperatures drop.)
This reality is resonating across the globe, far beyond Iceland. Nine out of 10 hottest Julys ever recorded have occurred since 2005. July was the 43rd consecutive July to register temperatures above the 20th-century average.
The melt rate has been called “unprecedented,” as the all-time single-day melt record was damaged. This happens in August as ice sheet lost a mind-blowing 12.5 billion tons of water in one day.
It is worth basic cognitive process that Greenland ice sheet contains enough ice to increase global sea levels by 20 feet.
A important problem is that most of sea ice around Alaska, and in greater Arctic, is young. Over the past few decennia, the older, thicker, multiyear sea ice has been melted. Away by warmer ocean and air temperatures.
(And this July, the seas around much of Alaska. The Beaufort and Chukchi seas, were some 9 or 10 degrees Fahrenheit above normal, noted Meier.) Only the thin, more assailable sea ice remains as Climate Changes.
The weather, swayed by climate, is often warmer than it was last century. The resulting, relentless ice loss is one of the most conspicuous results of rapidly heating climate.
