Kako će izgledati sjever Zemlje za 50 godina?

Beringov morski prolaz između Amerike i Azije biće bez leda i pun života, ako se globalna temperatura poveća za 3 stepena Celzijusa.

The researchers drilled down 700 meters through rock and sludge to retrieve sediments deposited during the Pliocene Warm Period, 3.5 to 4.5 million years ago.
Ravelo's team found evidence of similar amplified warming at the poles during the Pliocene Warm Period.
Analysis of the sediment samples indicated that average sea surface temperatures in the Bering Sea were at least 5 degrees Celsius warmer than today, while average global temperatures were only 3 degrees warmer than today.
