Thank you - that was indeed my primary point. Was a good article yesterday about the "Anthropocene", https://news.ycombinator.com/item?id=40079014, where if you look at graphs of things like temperature, CO2 concentrations, methane concentrations, etc., that the last hundred or so years just basically show a vertical line.

I did not. The Earth has warmed and cooled even more rapidly before.

If you have a source or are referring to something specific, please enlighten us.
