Global Warming Not Featured in New Hurricane Study is an article by Patrick Michaels at TCS Daily about a recent study on hurricanes.
Let's look at their results more carefully. Figure 1 shows the trend in an index of "moist static stability." Essentially, strong hurricanes can more easily form when this index value is low. In five of the six ocean basins, the authors find a statistically significant decline in moist static stability. But it's especially interesting to note that climate models (run under scenarios of increasing carbon dioxide) are also consistent in their forecasts of temperature changes in the lower atmosphere. They all report that the atmosphere will become more stable (e.g., Knutson and Tuleya, 2004). But that's the opposite of what's shown in Figure 1. So the only way to make the case that these changes are carbon dioxide-induced is to ignore the climate models, and who's willing to step forward and do that?
