Eh may as well throw some more information out before I go hit the bars...
2011 on pace to set record for most expensive year for natural disasters
"The United States has seen eight weather disasters this year exceeding $1 billion each in damage, and the annual hurricane season has hardly begun...The record is nine in a single year, in 2008."
Effects to crops and water supplies we are seeing right now
"In Iowa, even without admitting that climate change is real, farmers are acting as if it is, spending millions of dollars to alter their practices. They are adding tile drainage to their fields to cope with increased floods, buying bigger machinery to move more quickly because their planting window has become shorter, planting a month earlier than they did 50 years ago, and sowing twice as many corn plants
per acre to exploit the additional moisture"
