The warmists had decided in 2005 that Hurricane Katrina was caused by carbon dioxide emissions and held up Katrina as the smoking gun and the "clarion call" in their movement; but when their predictions for more severe hurricane seasons in the ensuing years came up empty, they distanced themselves from hurricanes and moved on to the Bay of Bengal claiming that carbon dioxide emissions are causing cyclone activity there (Destruction on a global level, Bangkok Post, December 17, 2009).

Yet, cyclones have been forming regularly on the Bay of Bengal for hundreds of years. The area has a history of severe and destructive cyclones with more than a hundred cyclones recorded since 1732. Of the 30 deadliest cyclones only two, Nargis and 02B, occurred after the year 1979 that marks the end of the last cooling period and the year that global warmists cite as the beginning of the current warming trend.

The most devastating cyclone on record hit East Pakistan in 1970 and became the proximate cause of the separation of that region into the new country we know as Bangladesh. The second most severe cyclone hit Kolkata in 1737. In fact the 8 worst Bay of Bengal cyclones struck while atmospheric CO2 was less than 300 ppm. It is not possible to conclude from historical cyclone data that they are caused by carbon dioxide. It cannot be argued that Bay of Bengal cyclones can be moderated by lowering CO2 emissions.
