From the results presented in Kossin et al. the «suggestions» of increases in
intense tropical cyclone activity in regions other than the Atlantic basin are not really so well supported, at least for the last 23 years.
Based upon the new results of Kossin et al. (GRL, 2007), it looks like the IPCC SPM just barely covered itself in its proclamations on observed hurricanes: There is observational evidence for an increase
of intense tropical cyclone activity in the North Atlantic since about 1970, correlated with increases of tropical sea surface temperatures.
However, the IPCC has found that, «more likely than not,» global warming will drive an increase in
intense tropical cyclone activity in the western North Pacific and North Atlantic by late in this century.
September's massive assessment from the Intergovernmental Panel on Climate Change (IPCC) found only «low confidence» that
intense tropical cyclone activity had increased measurably since 1950, according to Science Insider.
Intense tropical cyclone activity has increased since about 1970.
«Confidence that global warming is increasing
intense tropical cyclone activity has dropped since the [UN IPCC] panel's 2007 report»
There is observational evidence for an increase of
intense tropical cyclone activity in the North Atlantic since about 1970, correlated with increases of tropical sea surface temperatures.
