The 2012 Consensus Statement on Climate Change and Coral Reefs: There is much that is good about the statement ... but there is some that is not.

Subject Index Summary
Droughts (North America - Mexico): Climate alarmists warn of all sorts of weather disasters, including droughts, as the Earth recovers from the debilitating chill of the Little Ice Age and begins to experience the more benign temperatures of the Current Warm Period. Does history vindicate them? This question is explored via brief reviews of several papers investigating the occurrence of droughts in Mexico.
