Arctic's Baffin Island Starts to Melt!

Baffin Island, the largest island in the Arctic Canadian Archipelago, reveals from it's sediment that it is undergoing a major warming trend, probably as a result of global warming.

As part of a 21,000-year cycle, ( Milankovitch Cycles ),the Arctic has been receiving less summertime energy from the Sun over the last 8,000 years because of a well-established "wobble" in the Earth's solar rotation – the Earth is now 0.6 million miles further away from the Sun during the Arctic summer than it some 2000 years ago. Despite this, the area is warming up, as proven from the sediment cores taken from the bottom of the lake. Further proof, that warming is in fact taking place at an unprecedented level.
