The IPCC, and its grumpy band of Climategate alarmist scientists, predicted extreme climate change from human caused global warming - specifically, they predicted more frequent and more severe hurricane landfalls - they were wrong

Read here. The adjacent chart reveals the number of days between landfalls of a major hurricane striking the U.S. Since the last Category 3, 4 or 5 hurricane strike, it's been 2,412 days and counting.
Since 1900, that is the longest span ever between major landfalls. And this significant climate science factoid is contrary to the IPCC "experts" whose consensus prediction categorically claimed that these large devastating storms would be more intense and more frequent, due to the increasing human CO2 emissions and global warming.
As is obvious to even the most fanatical believer in the CAGW religion, the scientific, empirical evidence readily documents that the CO2-alarmist "experts" have been spectacularly wrong.
With that said, the U.S. is long overdue for a major severe hurricane strike and it could well happen in 2012. Then again, it might not. Either way, the IPCC has proven to be incapable of any scientific predictive skill.
