Marine species evolved, thrived, and diversified in 35 to 40°C ocean temperatures and CO2 concentrations “5-10x higher than present-day values” (Voosen, 2019 and Henkes et al., 2018).

I. The insignificance of modern “global warming”
Today’s ocean temperatures average about 16°C. CO2 levels hover around 400 parts per million (0.04%).
The oceans have warmed at a rate of just 0.015°C per decade since 1971 in the 0-700 m layer according to the IPCC (2013). This warming rate isn’t detectable when considering overall long-term changes in this layer (Rosenthal et al., 2017) during the Holocene.

News reporting of the recent heat wave in France and other European countries was accompanied with the usual blame on humans for causing the event. For example, here’s the CBS News headline: Record-breaking heat is scorching France. Experts say climate change is to blame.
While it is possible that the human component of recent warming might have made the heat wave slightly worse, there are three facts the media routinely ignore when reporting on such “record hot” events. If these facts were to be mentioned, few people with the ability to think for themselves would conclude that our greenhouse gas emissions had much of an impact.
