Unpredictable weather is making life difficult for insurers — see today’s special report: ”Extreme weather batters the insurance industry.”

Every year forecasters at Colorado State University take their most educated guess as to how the next year’s hurricane season will unfold. It always draws headlines, but as history shows, that initial “best guess” is usually somewhat far off the mark.

An analysis of 10 years of first forecasts for the subsequent June-November storm season shows the number of tropical storms generally exceeds expectations, sometimes by a fair bit. As you go up the scale to full-blown hurricanes and on to the more intense “major hurricanes,” the disconnect remains the same.

In 2006, for example, the number of major hurricanes matched the predicted number of all hurricanes, period. In 2010 the number of hurricanes was greater than the expected incidence of all tropical storms. (In fact 2010 is considered by experts to have been a relatively heavy storm year, despite the fact none actually made a crucial U.S. landfall).

A Reuters exclusive details the emergence of two anti-corporate, WikiLeaks-style websites in Europe, both called GreenLeaks. The sites promise to leak confidential documents regarding environmental abuses by a host of industries.
