"The Global Warming Smoking Gun: 1910 to 1940"

How the burning of fossil fuels was linked to a warming world in 1938



This month marks the 75th anniversary of Guy Callendar's landmark scientific paper on anthropogenic climate change

Here is the illustration produced by Hawkins and Jones to show how Callendar's findings, published in 1938 and updated in 1961, match a modern-day temperature reconstruction ( CRUTEM4) of global land temperatures for the period 1850-2010.


Comparing historical reconstructions of near-global land temperatures using CRUTEM4 (black, Jones et al. 2012) with Callendar (1938) (red) and Callendar (1961) (blue), using a reference period of 1880-1935. The CRUTEM4 estimates are for 60?S-60?N (to accord with Callendar’s series), with grey shading representing the 95% uncertainty. Image: Ed Hawkins and Phil D. Jones
