According to Rebecca Lindsey of the National Climate Data Center the list of impacts from the U.S. drought seems endless.  There have been record-low hay stocks,  significant damage to house foundations, ethanol and beef processing plants idled, and mandatory water restrictions.

If global warming is caused by humans and that cause has a signature that scientists can point to in the debate, then the scales tip further for increased global action. Jeff Severinghaus, a climate researcher says his new study...

One of the ways we can tell how climate is changing is how other living things adapt.  Whether it is the sugar maple tree or the swallowtail butterfly, even the most casual observer detects the differences.
