'We are headed toward a seasonally ice-free Arctic Ocean, and this year is another nail in the coffin.”
This appears to be the lowest extent of the year, the National Snow and Ice Data Center said. In response to the setting sun and falling temperatures, ice extent will begin increasing through autumn and winter. However, a shift in wind patterns or a period of late-season melt could still push the ice extent lower.
The amount of summer sea ice in the Arctic has been steadily shrinking over the past few decades because of man-made global warming, according to the National Oceanic and Atmospheric Administration and NASA.A Siberian heat wave in the spring began this year’s Arctic sea ice melt season early, and with Arctic temperatures being 14 to 18 degrees Fahrenheit higher than average, the ice extent kept declining.
Bitz said that Arctic sea ice is an asset for our planet, but it is disappearing rapidly."In my lifetime, the sea ice at the end of summer has decreased by 50%, and now we’ve found that late summers may be ice-free in a few decades.
