The Tipping Point and Global Warming

A scary article appears in the Independent Online Edition describing how global warming has past the point of no return.

"The greatest fear is that the Arctic has reached a 'tipping point' beyond which nothing can reverse the continual loss of sea ice and with it the massive land glaciers of Greenland, which will raise sea levels dramatically."

The implications are huge, so we are told by experts. Losing the sea ice of the Arctic is likely to have major repercussions for the climate. There could be dramatic changes to the climate of the northern region. The creation of a vast expanse of open water where there was once effectively land will have a very big impact on other climate parameters.

Now I'm tempted to think that this 'vicious cycle' of global warming warming will eventually hit the boiling point. How long will it take before the oceans reach the 'boiling point'?

Repent all ye sinners the end is nigh!
