Ms. Lela, I suggest  you consider taking a few remedial high school classes in math and science before embarrassing yourself again with comments like this. The vast majority of world scientists have given the answer to your "WHY" question: the huge amount of CO2 released into the atmosphere by human activities and ventures. You just don't like their answer. What are your science credentials? Masters? Doctorate? Sorry dear, but scientists as a group are about as apolitical as people come; most scorn politics. Their world revolves around facts and analysis. What's the basis for your assertion that scientists are politically driven?
