restarted, for reasons scientists don't understand. Current computer models of the climate cannot reproduce the observed sudden shut down or start up of the Meridional Overturning Circulation at the beginning and end of the Younger Dryas period. Other sudden shut downs of the Meridional Overturning Circulation observed in ice core and ocean sediment records are not thought to be due to sudden melt water floods into the North Atlantic. These events may have happened simply because Earth's climate system is chaotic, or perhaps because some critical threshold was crossed when increases in precipitation, river run off, and ice melt put enough fresh water into the ocean to shut down the Meridional Overturning Circulation. Global warming will increase precipitation, river run off, melting of the Greenland ice sheet, and melting of polar sea ice, all of which will increase the amount of fresh water flowing into the critical deep water formation areas by Greenland. In the 2007 IPCC Fourth Assessment Report Summary for Policymakers (PDF File) it states that, based on current model simulations, it is very likely (90 99% confidence) that the meridional overturning circulation (MOC) of the Atlantic Ocean will slow down during the 21st century.

Today's science is such that any long term assessments of the MOC cannot be made with confidence. A 2012 paper in Proceedings of the National Academy of Sciences used computer modeling to show that abrupt climate events in the past occurred as a result of a change in ocean currents due to the Bering Strait closing off because of low sea levels. The Bering Strait is the 50 mile wide gap that separates Siberia from Alaska. A shut down of the Meridional overturning circulation would suddenly decrease the amount of heat in the North Atlantic, leading to much colder temperatures in Europe and North America. A 2003 report prepared for the Department Womens Adidas Gazelle Uk of Defense outlines what would happen if an abrupt climatic change similar to the 8200 years before present event were to recur today:Annual average temperatures would drop up to 5 F in North America, and up to 6 F in northern Europe. This is not sufficient to trigger an ice age, which requires about a 10 F drop in temperature world wide, but could bring about conditions like experienced in 1816 the famed "year without a summer".

also confirms the scientific consensus that is very unlikely the MOC will undergo a large abrupt transition during this century.

In that year, volcanic ash from the mighty Tambora volcanic eruption in Indonesia blocked the sun's rays, significantly cooling the globe. Snow fell in New England in June, and killing frosts in July and August caused widespread crop failures and famine in New England and northern Europe. Multi year droughts in regions unaccustomed to drought would affect critical agricultural and water resource regions world wide, greatly straining food and water supplies. Dr. Broecker argued that a global warming induced abrupt climate change is not likely to occur until 100 years or so. Adidas Gazelle Og Maroon Size 9
