North Pole Becoming Ice Free

Arctic could see ice-free summers in 100 years, other sources say a decade or two.

Looking at data on the rate of ice melt in the Arctic, researchers from the University of Arizona and other universities concluded that the rate is accelerating and that no foreseeable natural forces will counteract that acceleration. As a result, ice-free summers loom.

The situation will have worldwide ecological impact, the researchers said. The progressive melt will cause sea levels worldwide to rise, flooding coastal areas, where a substantial portion of the world's population lives. Huge sections of Bangladesh, for example, consist of river delta at sea level. The melt could also thaw permafrost, which could lead to an increase of greenhouse gases in the atmosphere.

The increasing rate of ice melt is already having some impact on people and animals in the Arctic. Other researchers have speculated that the progressing ice melt around Siberia may lead to a summer Northeast passage connecting Japan to Europe in a decade or so.

This was the reason for Canada sending gunboats to protect the sea passages and oil fields in my previous post. With shipping easier this is a more valuable and vulnerable area.
