Hansen et al, 2009.
These climate scientists went back as far as the data partially permitted - 1880 - which hardly describes climatic conditions eons ago.
And the data presented can merely predict what has happened since, maybe, 20-30 years.
The conjecture is still in its infantile stage yet it has already convinced so many!
No wonder demagogues of the past could convert people’s normally semi-skeptical beliefs to absolute “True Belief”.
Like it or not, that’s not yours truly. I have substantive doubts about so many claims that I hardly expect to convince those who’ve already been convinced otherwise.
You also doubt evolution. Strangely, the two scientific theories rejected by religious conservatives are…. evolution and climate changne.
...and of course the world is only 6000 years old and my ancestors cavorted with dinosaurs.
