Take a look at NASA's Goddard Space flight Center

Here they are suggesting that Global Warming and the increase of CO2 will result in greatly increased rainfalls.

Measurement of Western US snowfalls.

The study of the Earths resources in colour, and much more.

NASA is sending a Mission to Mars later this year to study its upper atmosphere. "The Mars Atmosphere and Volatile Evolution Mission" (MAVEN), set to launch later this year.
As a 'sweetner'
If you register your name with NASA's Goddard Center, they will add your name to the DVD plaque thats going to Mars.
So hurry , you have just 54 days left to register and get your name to Mars.
