In Georgia and Florida, dry conditions caused failing crops and water shortage alerts. Lake Okeechobee in South Florida, second only to Lake Michigan as the largest fresh water lake in the U.S., and a source of water for millions of people and the Everglades, reached its lowest level ever. Levels were so low that <a href=\"http:\/\/www.sciencedaily.com\/upi\/index.php?feed=TopNews&amp;article=UPI-1-20070605-18464300-bc-us-artifacts.xml\">archeological artifacts were revealed<\/a> on the exposed lake bottom.<\/p>\n<p>The region was also hit with <a href=\"http:\/\/www.ncdc.noaa.gov\/oa\/climate\/research\/2007\/fire07.html\">wildfires<\/a> reported as the <a href=\"http:\/\/www.msnbc.msn.com\/id\/19435750\/\">most extensive since 1898<\/a>. In Georgia and Florida alone, <a href=\"http:\/\/www.nifc.gov\/fire_info\/ytd_state.htm\">more than 1 million acres have burned<\/a> so far in 2007. At the Florida Climate Summit in Miami last week, I heard Governor Crist report that this year there were wildfires in all but 3 of the more than 90 counties in the state.<\/p>\n<p>In the southwest, California, Nevada, Colorado, and Utah were hit with <a href=\"http:\/\/www.livescience.com\/environment\/070706_ap_sizzle.html\">sweltering heat<\/a>. Record-breaking or near record-breaking high temperatures were recorded in Reno, Las Vegas, Boise, and Spokane. In Phoenix, Las Vegas, and other cities, temperatures hovered near <a href=\"http:\/\/www.msnbc.msn.com\/id\/19619641\/\">110<sup>o<\/sup>F or higher<\/a>.<\/p>\n<p>Meanwhile, the central part of the U.S. &#8211; especially Texas, Oklahoma, and Kansas &#8211; is awash in water. You might think these folks would appreciate moisture after last year&#8217;s severe drought with widespread wildfires and crop failures. But not this much moisture. The <a href=\"http:\/\/www.voanews.com\/english\/2007-07-02-voa74.cfm\">floods produced by near-record rains<\/a> have cost lives, destroyed property, and contaminated waters and soils.<\/p>\n<p>Is this extreme weather due to global warming? It&#8217;s impossible to attribute a specific meteorological episode to a climate trend, but global warming does make <a href=\"http:\/\/www.environmentaldefense.org\/page.cfm?tagid=1405\">extreme weather events<\/a> more the norm than the exception.
