Other Sources and Notes:
The values cited above are based on leading climate change literature, including the Stern Review and Hansen et al "Global Temperature Change." While they require validation, the values provided are generally indicative of the emerging scientific consensus that climate change is happening faster and more extensively than previously realized. Specific sources and assumptions include:
- GHG and Temperature: Stern Review, Ch 1, p. 12-13. PPM estimate baed on midpoint of IPCC projection. Temperature increase is estimated for 2050 and 2100 based on eventual stabilization temperatures (625 PPM: 2-6C/3-11F; 925 PPM: 3-8C/5-16F ).
- Sea Level: Lower limit from IPCC 2007 (28-43 cm); upper limit from Rahmstorf, Science 2006.
- Income Loss: Stern, ExSum, p. x, viii.
- Species: Hansen et al. ~60% endangered with warming of 3C/5F. Stern, ExSum, p. vi. 15-40% face extinction after 2C/4F of warming.
