Sometimes Gaia sends the faithful tests, and sometimes she sends signs.
For example Sandy was a sign to enhance our carbon faith, but record cold at Cancun was a test of faith. Obama getting snowed out of Copenhagen was also a test - as is the Gore Effect.
It is easy to distinguish a sign from a test. When something happens contrary to your beliefs, it is a test. When an event happens which confirms your beliefs, it is a sign.
The important thing to remember is that no matter what happens, it is proof of global warming.
