two, even if the US stops funding something others are not banned from funding it are they? Let those who believe put their money where their mouth is.
No, but lets not allow politicians who refuse to take scientific experts seriously --mostly because they receive donations from oil companies that lobby to them -- remove us from the front line of Global Warming research. The various branches of the US military, along with NASA (you know.. the people smart enough to send rockets and satellites to the moon and other planets..), undoubtedly believe that Global Warming is real, and that's because their scientists have found the evidence showing it's real.
Taking us out of Global Warming research would severely cripple the effectiveness of said research.
