Wrong again.The questions on that page do not state what you claim, they ask about the ratio of natural causes to anthropogenic changes between 1920 and 1940.
Your claims are once again bullshit.
Here is the question that was asked: What fraction of global warming since the mid-20th century can be attributed to human induced increases in atmospheric greenhouse gas (GHG) concentrations?
I've got a newsflash for you. The words "since the mid-20th century" don't refer to the period from 1920 to 1940.
You really are illiterate.
