Arctic Ocean Could Be Ice-free In Summer Within 100 Years, Scientists Say

Arctic Ocean Could Be Ice-free In Summer Within 100 Years, Scientists Say

Another day, another Daily Sign Of The Apocalypse:

The team concluded that there were two major amplifying feedbacks in the Arctic system involving the interplay between sea and land ice, ocean circulation in the North Atlantic, and the amounts of precipitation and evaporation in the system.

Such feedback loops accelerate changes in the system, Overpeck said. For example, the white surface of sea ice reflects radiation from the sun. However, as sea ice melts, more solar radiation is absorbed by the dark ocean, which heats up and results in yet more sea ice melting.

Such substantial additional melting of Arctic glaciers and ice sheets will raise sea level worldwide, flooding the coastal areas where many of the world's people live...
