This graph shows atmospheric CO2 from 1820-1960. Most of the consumption of fossil fuels takes place in the 20th century, generally after 1940.
This graph show temperature change:
Note that much of the warming took place on the left side of the graph, with a decline after 1940, when CO2 concentrations increase and fossil fuel consumption increases. When I pointed this out to an acquaintance who BELIEVES, his response was to call me a pragmatist instead of a believer in science! This is fast becoming a religiously based system of thought.
