On climate change responsibility
Today NewScientist reports “The seven deadly sinners of global warming“. What captured my attention was the visualization map telling us that US, China, Russia, Brazil, India, Germany and the UK are responsible for more than 60% of the global warming between 1906 and 2005. Their source is the paper “National contributions to observed global warming” by Matthews, Graham and Keverian (freely available Environmental Research Letters, DOI: 10.1088/1748-9326/9/1/014010).
The top countries change depending how you make the accounting but they can group in two: industrialized countries and deforestation countries. The review from NewScientist put Matthews on my to-read list.
