2012 SkS Weekly Digest #30
Posted on 30 July 2012 by John Hartz
With Climate Change Cluedo: Anthropogenic CO2, Tom Curtis has created a new template for future SkS articles based on the board game of Cluedo(Clue in the US). In this article, Curtis sets forth ten main lines of evidence that humans have caused the rise in CO2 levels since the beginning of the 20th Century by burning fossil fuels. Every other hypothesis makes a host of predictions that do not pass the test of the evidence.

Quote of the Week
"Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause." - Richard Muller

Scientific Term of the Week
Energy balance: The difference between the total incoming and total outgoing energy. If this balance is positive, warming occurs; if it is negative, cooling occurs. Averaged over the globe and over long time periods, this balance must be zero. Because the climate system derives virtually all its energy from the Sun, zero balance implies that, globally, the amount of incoming solar radiation on average must be equal to the sum of the outgoing reflected solar radiation and the outgoing thermal infrared radiation emitted by the climate system. A perturbation of this global radiation balance, be it anthropogenic or natural, is called radiative forcing.

SkS in the News
The Walker Institute for Climate System Research was established at the University of Reading in Autumn 2006.
Our vision is to be a world leader in integrated climate system research in order to deliver better knowledge and understanding of future climate and its impacts for the benefit of society.
