From dry rivers to dead deer, drought's impact felt everywhere By Greg Botelho, CNN http://www.cnn.com/2012/09/15/us/drought-impact/index.html
Notice that the milder winters in the US due to higher average temperatures and almost no snow is the same effect in the winter.
The economic effects will probably only be understood over time, but ethanol is already a victim. http://www.huffingtonpost.com/2012/08/01/economic-effects-of-drought-2012-us_n_1728640.html
there's a diiference between global warming, and climate change. Global warming is undisputable and has been written about by scientists for the last 100 years. It is knowable and predictable and observable and unstoppable. Climate change on the other hand is widely believed to be caused by human activity and has only been observed for a short while. Global warming is no big deal because it happens so slowly that plants and a animals can over time adapt. Climate change is happening at a rate faster than we have ever observed so we don't know what the consequences will actually be.
Looks like it's getting colder. http://jonova.s3.amazonaws.com/graphs/lappi/65_Myr_Climate_Change_Rev.jpg
