Global Climate Lurching

Europe is kept warm by the Gulf Stream, the “Great Conveyor Belt” which transports warm water to the north. Changes in the conveyor belt mean changes in Europe’s climate, and more evidence is emerging the Belt can stop Conveying on the timescales of decades.

The findings, published January 14, 2011 in the journal Science, show that as the last Ice Age came to an end (10,000 — 20,000 years ago) the formation of deep water in the North-East Atlantic repeatedly switched on and off. This caused the climate to warm and cool for centuries at a time.
