The “science" makes a lot of different claims based on a lot of different lines of evidence. You can't "believe" all of it because it's full of inconsistencies. Do you believe the scientific data that shows less warming than predicted by climate models? Or the science that shows hurricanes aren't more frequent or more severe? I certainly don't believe alarmist interpretations of the science that cherry-pick computer simulations and try to frighten us with implausible worst-case scenarios. A better question is whether you mainly believe the models or the data, because in a lot of key areas they disagree with each other.
