As Iowa becomes submerged, environmentalists and global warming believers like myself are beginning to wonder how much proof Americans need before they realize what is happening to our world.
Scientists are currently predicting that the early consequences of global warming will be stronger, more erratic weather behavior. Some are now pointing to Iowa as the latest example of this. They have been saying it for years, as shown in this PDF issued by the National Wildlife Federation, or this from the Environtmental Defense Fund.
Both of these were issued in response to the Iowa Flood of 1993, and both said that 100 year floods (floods that typically happen in a given area once in 100 years) could happen as frequently as every 10 years by 2090. Now, 15 years later, some sources are reporting that the Iowa Flood of 2008 may be a 500 year flood.
If Katrina was the first wake up call about global warming for America, number two is here.
