Indeed, Ulli is correct. "Global warming" is a bit of a misnomer, and  
certainly an oversimplification. Climate change is a much better term.  
And, in general, the effects of climate change are so as to accentuate  
climatic patterns; more droughts and more extreme droughts; more  
rainfall and flooding, more extreme weather events (tornados,  
hurricanes, hail storms, ice storms), more frequent and more intense  
El Ninos/La Nina. This is all set against the backdrop of increasing  
global temperature. The extreme cold temperatures this winter in  
Europe are also characteristic of the hitherto established climatic  
norm being run off the rails.

Cheers,

Chris
