Tonight I attended a lecture titled "Climate change: Past, present and future" given by the British economist David F. Hendry of INET, Institute for New Economic Thinking, Oxford University (who is cited some 40.000 times on Google Scholar´s account). The lecture was very informative on certain points - for instance, I learned that UK´s carbon dioxide emmissions per capita was as high around 1860 as it was around 1975 (the second peak in UK history), and that carbon dioxide emissions per capital stock has gone down some 90 % in both the UK and US since its peak by that measure.
The lecture was arranged by the Oxford Martin School.
