Read here. IPCC Climategate scientists and their models predicted that disaster losses from severe weather events would increase from CO2-induced global warming. A new peer-reviewed study analyzing all the data since 1950 finds that climate model predictions are false - actual warming did not cause an increase.
"Independently of the method used,we find no significant upward trend in normalized disaster loss.This holds true whether we include all disasters or take out the ones unlikely to be affected by a changing climate. It also holds true if we step away from a global analysis and look at specific regions or step away from pooling all disaster types and look at specific types of disasters instead or combine these two sets of dis-aggregated analysis. Much caution is required in correctly interpreting these findings. What the results tell us is that, based on historical data, there is no evidence so far that climate change has increased the normalized economic loss from natural disasters."
