Climate Change Doubles Drought Stricken Area
Cally writes "The National Atmospheric Research Center has published research showing that the percentage of Earth's land area stricken by serious drought more than doubled from the 1970s to the early 2000s, and attributing this to global climate change. Interestingly, the lead author comments that 'droughts and floods are extreme climate events that are likely to change more rapidly than the average climate'."
The term global warming was coined to describe the phenomenon of the entire weather system heating up, not the lack of snow in New Jersey. When the atmosphere heats up, it has more energy. That means increased activity, such as droughts, hurricanes and yes, snowstorms.
Also, there has been a good bit of discussion that it's possible that the melting of the ice on the polar ice caps is diluting the salt of the oceans, causing the Gulf Stream to change course. That would have the effect of reducing the temperature in the Northeastern United States and Great Brittan. It might just get colder!

If you're not living on the edge, you're taking up too much space.
Crichton's book is a bad joke that has been thoroughly debunked.
I have not seen the show, but I have read about what you are talking about. A current theory is that Lake Agassiz, a 'super great lake', catastrophically drained into the upper Atlantic causing a shift in salinity, thus a shift in the temperature current flow, thus a shift in climate.

All this talk about historic climate change is like an ant talking about the nature of an elephant. We are too small, and the details are too big. To hear environmentalists talk about it, we are on the verge of disaster, but to hear geologists talk about it, we are just barely coming out of the last ice age. From a geological standpoint, everything I have read about says that our planet should be about 10 degrees warmer than what it is today. We're coming out of 'abnormal' climtes, and apparently inching back toward 'normal'. A google on "cenozoic ice age" will be instructive, as is this page: http://www.museum.state.il.us/exhibits/ice_ages/ "During most of the last 1 billion years the globe had no permanent ice." North and south pole ice is an anomaly.
