Is Global Warming Causing Hurricanes?

by John Hinderaker/Powerlineblog in Climate

Of all the claims that the alarmists make on behalf of anthropogenic global warming, perhaps the most outrageous is that hurricanes–think Katrina–are becoming more frequent and more severe as a result of human activity. Actually, hurricanes have not become either more frequent or more violent, which one might think would put the issue to rest. But the alarmists know they have reporters on their side, so inconvenient truths won’t be mentioned.

If you want to read all there is to know on this subject, check out this paper by Dr. William Gray, America’s leading expert on hurricanes. He minces no words in denouncing the fraudsters who have come to dominate climate “science.”

The US government has expended billions of dollars in recent years to promote the questionable idea that human-induced increases in atmospheric CO2 will cause dangerous changes to the global climate system. Massive government and media campaigns have been launched to promote the dangers of CO2-induced anthropogenic global warming (AGW) and related influences such as the anticipated increases in global tropical cyclone (TC) frequency and intensity as well as other severe weather events. Pro-AGW advocates have pushed to have this warming gospel accepted across the world and taught to our children in their regular school programs. AGW advocates want to worry the public as much as possible in order to be better able to increase their influence and funding support. …
After the very severe US hurricane landfalling seasons of 2004 and 2005, the public was more open and vulnerable to such arguments of CO2 induced increases in hurricane activity. A group of papers were rapidly published to exploit and to justify this assumption so that the authors might be able to jump onto the warming bandwagon and increase their potential for more federal grant support, publicity, and other envisioned gains.

Dr. Gray points out the obvious facts that refute the alarmists’ claims:

Although global surface temperatures appear to have increased during the 20th century by about 0.65°C or 1°F, there is no reliable data to indicate that increases in TC frequency or intensity changes occurred in any of the globe’s TC basins. Global Accumulated Cyclone Energy (ACE)1 shows significant year-to-year and decadal variability over the past 40 years (when global TC data is deemed reasonably reliable) but no period-long increasing trend. In fact, global TC activity has shown (red line) a distinct decrease over the last 20 years when CO2 amounts were increasing (Figure 2.1). Similarly, Klotzbach (2006) found no significant change in global TC activity during the period from 1986-2005 when tropical SSTs and CO2 amounts were rising (Figure 2.2). See section 13 for more discussion.

Then there is this; there were more Caribbean hurricanes during the era of global cooling than the era of global warming:



Dr. Gray explains in detail why the alarmists’ reasoning is wrong; they don’t know much about hurricanes.
