This summary updates Monckton of Brenchley (2013), read at the World Federation of Scientists’ 2012 Seminars on Planetary Emergencies. The paper applied inter-temporal investment appraisal to mainstream IPCC climatology by comparing the cost of Australia’s 10-year CO2 tax (Parliament of Australia, 2011) with the benefit in the cost of warming-related damage the tax might avoid.
The Science and Public Policy Institute has been asked to comment on the apparent inconsistency between the news that July 2012 was the warmest July since 1895 in the contiguous United States and the news that the Meteorological Office in the UK has cut its global warming forecast for the coming years. The present paper is a response… Read More »

Your Newsnight segment on Arctic sea ice (BBC2 TV, 8 September 2012) featured a “scientist” who said ice loss since a high point in 1979 would cut the Earth’s albedo and, by this feedback, cause warming equivalent to 20 years’ global CO2 emissions. On the IPCC’s current central climate-sensitivity estimates, 20 years’ CO2 emissions would only warm the… Read More »

Global CO2 emissions per unit annual increase in atmospheric CO2 concentration show no significant trend over the 49 year timescale of the available data (1960-2008). The mean emissions/concentration-growth ratio over the period was 15.5 Gte CO2 ppmv–1. Current central estimates are that CO2 concentration will rise by 345 ppmv over the 21st century, during which CO2-driven warming is… Read More »

This note, prepared for distinguished scientific delegates at the 2012 annual seminars on planetary emergencies of the World Federation of Scientists, demonstrates the application of a much-simplified method of climate-mitigation investment appraisal to the recently-introduced Australian carbon dioxide tax. For the first time, mainstream climatological and economic-appraisal approaches are combined in a simple but robust appraisal method. The… Read More »
