There is no man-made global warming. In fact a new cooling cycle began in 1998, as a result of the cyclical upchurning of cold ocean currents, which themselves are dependent on sunspot activity.

The current political hysteria over warming is an attempt to cash in before global cooling makes those claims self-evidently bogus.
