Warmists undermined by their own graph
Romm is featuring this graph from “Evangelical Christian” John Cook.
Note that temperatures rose as fast from 1910 to 1940 as they did from 1970 to 2000.
This is solid evidence that the warming is not due to CO2, which only rose 10 ppm from 1910 to 1940. If you use the latest climate science 30 year lag rule, their problem gets even worse – because the 1910-1940 rise was due to the tiny rise in CO2 from before the automobile was invented.
Note also the chartmanship involved above. What looks like a dizzying rise in temperature is no such thing. The graph is scaled in tenths of one degree so the rise in both periods is in fact trivial
