65 Million Years of Climate Change

...and "humans" have been present on earth for anywhere between 200,000 and 300,000 years.
So is rapid warming (since the Industrial Revolution) a deception?  or coincidence?

You decide.

For example, global temperatures increased by five to eight degrees Celsius during a period known as
Paleocene–Eocene Thermal Maximum  and it lasted for about 200,000 years.  Massive carbon release into the atmosphere lasted for up to 50,000 years.

And if you want to read about volcanism--and what its contribution to global warming likely contains--this North Atlantic Igneous Province is a great read.
