This cover today is making the rounds in the alarmosphere, where a single storm, a single data point in the hundreds of hurricanes that have struck the USA during its history, is now apparently “proof” of global warming causing bad weather. It is just another silly example of Tabloid Climatology™.
Hurricane expert Dr. Roger Pielke Jr. says:
The only accurate part of this Bloomberg BusinessWeek cover is “stupid”
There, I fixed it for you.
The US Has Had 285 Hurricane Strikes Since 1850: ‘The U.S. has always been vulnerable to hurricanes. 86% of U.S. hurricane strikes occurred with CO2 below Hansen’s safe level of 350 PPM’
If there’s anything in this data at all, it looks like CO2 is preventing more US landfalling hurricanes.

Normalized US Hurricane Damage 1900-2012, Including Sandy
The graph above shows normalized US hurricane damage, based on data from ICAT, which applies an extension to the methodology of Pielke et al. 2008. The 2012 estimate for Sandy comes from Moody’s, and is an estimate. The red line represents a linear best fit to the data — it is flat.
