Well, of course there are people/organisations trying to score as much money as they can from the climate change. I don't know for sure about the climate change, but it seems to change differently in different areas, here we get warmer winters, some areas get higher annual perception etc.
However I take this at ease, the ecosystem has always been changing and I don't think humans will destroy it by some centigrades. But we should reduce CO2 emissions for our own health (look at China) however I won't go militant about it because I know increased travel is needed for the economy to grow.
