As Hurricane Ike makes its way towards the Lone Star State, we must ask if this is a natural storm, or one that was made by us? The answer is we simply don't know. When Katrina hit New Orleans, it gained power in the days leading up to that strike from warmer than average waters in the Gulf of Mexico. Is the warming due to climate change? Very likely.
I'm not saying that the hurricane was formed due to climate change, but warmer waters in the Gulf definitely can make them stronger. So as Thomas Friedman says:
When hurricanes and other natural disasters hit, insurance companies and the general media often call them "acts of God." Have we introduced so much CO2 into nature's operating system that we no longer know where nature stops and we start in shaping today's weather? We no longer know..."
And that is what is truly scary.
