Global warming and the spread of disease

Do you need more evidence that global warming is both very real and very bad? Consider this from the Post: "Global warming -- with an accompanying rise in floods and droughts -- is fueling the spread of epidemics in areas unprepared for the diseases, say many health experts worldwide. Mosquitoes, ticks, mice and other carriers are surviving warmer winters and expanding their range, bringing health threats with them."

Will it take some epidemic to stir us into action?
