As the world burns
Okay, I stole that headline from Mother Jones. But evidence of global warming seems to be more and more evident each day. Of course, it's hard to point to any one hurricane or heat wave or drought and say "Ah hah!--Global warming!" But there are an awful lot of hurricanes, heat waves and droughts going on right now. The NY Times has an article about the ongoing drought in the Mississippi and Ohio valleys which shut down part of the Ohio River to barge traffic on Friday, and threatens to shut down more of the Ohio and Mississippi soon. Barges running aground have already delayed shipments of petroleum products, coal, chemicals, agricultural goods and road-paving materials.
