The Intergovernmental Panel on Climate Change (IPCC), representing the overwhelming scientific view on climate change, in its 2001 technical summary was cautious about the connection between hurricanes and climate change.
"Based on limited data, the observed variations in the intensity and frequency of tropical and extra-tropical cyclones and severe local storms show no clear trends in the last half of the 20th century, although multi-decadal fluctuations are sometimes apparent," it stated on the historical data.
As to projections on what might occur with increasing buildup of carbon dioxide the IPCC expressed cautious concern. "There is little consistent evidence that shows changes in the projected frequency of tropical cyclones and areas of formation. However, some measures of intensities show projected increases, and some theoretical and modelling studies suggest that the upper limit of these intensities could increase. Mean and peak precipitation intensities from tropical cyclones are likely to increase appreciably," it stated. [1]
