Alaska bakes under heat wave linked to climate change

Alaska residents accustomed to subzero temperatures are experiencing a heat wave of sorts that is shattering records, with the thermometer jumping to more than 16.7 degrees Celsius above normal in some regions.

Cities and towns in the northern half of the state, including Wainwright, Nuiqsut, Kaktovik and Barrow (also known as Utqiagvik), could see temperatures soar 14 to 22 degrees Celsius above normal this weekend as the warm trend continues.

The dramatic warming Alaska has experienced in recent years -- which is partly linked to a decline in sea ice and Arctic ocean warming - had wreaked havoc on local communities, wildlife and the economy.

Many recreational sled dog races have had to be canceled this year and the routing of the famed Iditarod race had to be changed as what is normally solid sea ice was open water on part of the race route.

Crab fishing has also been affected as the sea ice used as a platform for fishermen was non-existent or too thin in some areas.

Seal population is also likely to be affected in the coming months as some of the species give birth on solid ice.

The warmer temperatures have melted the rive ice to the extent it is no longer safe for truck or car travel."

Global warming had led to the lowest ice levels in the Bering Sea -- which connects with the Arctic Ocean - since 1850, when sea ice records began.
