From Sharon Ellis:

Re: Is global warming preventing an Ice Age? (Dec. 17): In my opinion Global Warming is hastening an Ice Age not preventing it.

This warming is temporary. Once enough fresh water has melted from the North and particularly the South Pole (because it is larger) it will stop the North Atlantic Heat Pump from functioning. Fresh water is lighter than salt water so it cannot sink to the bottom and make its way back to the Equator to be warmed. This means that warm water that normally flows from the Equator, north, will no longer flow. When this happens the weather patterns will change and an ice age will begin.

It is pointless to say that we can slow green house emissions by the year 2020 for example. By then we will be in an ice age and to believe otherwise is naive.
