A pattern is forming in my head.

Source: “A 485-million-year history of Earth’s surface temperature”, E.J. Judd et al. Temperatures are averages for geological periods. Shaded area shows values with a 68% probability.

Let's discuss it.

Warning, it's not “good news”. I think we fucked up so badly that quiet literally a “Dark Age” is coming. This is a rough “first pass” of how some new papers are coming together for me. This is MY OPINION, not “science”.

YOU HAVE BEEN WARNED.

So, a few weeks ago I wrote a paper breaking down the paper this chart is from.

One of the things that stuck in my head was the finding that there was an apparent pattern of +8°C temperature increase for each doubling of atmospheric CO2 (2XCO2).

Judd et al. present a record of GMST over the past 485 million years that they constructed by combining proxy data with climate modeling (see the Perspective by Mills). They found that GMST varied over a range from 11° to 36°C, with an “apparent” climate sensitivity of ∼8°C
