Original caption: "The cost of extreme weather events is rising rapidly and could reach a trillion dollars by 2050. source data: IPCC, 2001" Please note that neither this graph or its revision below includes data from 2000-2005.

This extrapolation graph entitled, "Average yearly inflation-adjusted dollar cost of extreme weather events worldwide," which I used the free 'R' program to create from the data here has been placed in the public domain. The y-axis is "billions," (0 to 1000, although the tick marks omit 1000) the x-axis is "decade," (1960 to 2040, although the data ranges from 1950 to 2050) and the third-degree polynomial extrapolation has an R-squared value of 0.98.

Please note that neither of these graphs include any data from 2000-2005.

The earlier proposed revision had confidence bands, an additional degree of freedom, and a nonnegative domain. Its proposed caption was, "The cost of extreme weather is rising rapidly and could reach four trillion dollars by 2020. Historical source data: IPCC, 2001. Some of the increase is due to greater exposure such as building on the coast." The emerging consensus was that it should have been based on a logistic sigmoid fit because the underlying cause is, but the sigmoid had a much weaker fit to the data.
