I down voted because this is (1) whataboutism, (2) I can't see the analogy.

That increased CO2 emissions should cause a temperature increase has been proposed over 100 years ago. They did not look at climate change recently and suddenly decide "lets blame CO2".

The case for man made climate change is pretty strong. Look at these graphs and tell me which graph correlates most strongly with global temperature increases: https://www.bloomberg.com/graphics/2015-whats-warming-the-wo...
