...add CO2 -- the evil greenhouse gas -- to the atmosphere. While that comment is somewhat tongue-in-cheek, it isn't entirely TIC.

United States Hurricanes Are Not Getting Worse
Remember how, after Hurricane Katrina in 2005, the media was filled with "hurricanes are going to get worse!" stories? Here is how well that forecast has worked out.
A recent episode of Weather Geeks had a meteorologist researcher proclaim there is "no signal" in the trend of tornadoes. Wrong. He didn't want a trend because the pro-global warming crowd wants us to believe global warming is more serious than it is. I agree with him that the data on all tornadoes is unreliable due to changes in radar, storm chasing, etc. But, for strong tornadoes, we have a pretty good idea of how many occur each year. The trend in strong tornadoes the last 50 years? Down.
Yes, global warming is a genuine issue. And, some of its effects are serious. But, weather-related storms are not getting worse in the United States or worldwide.
