[Bernard Marx]

Here’s a fact: In 2016, Earth reached its highest temperature on record

Here's another fact: we have approximately 200 years of temperature records compared to the 4.5 billion year age of the Earth. In essence, we know nothing.

Now that man burns fossil fuels, we should expect Earth to hold a 59° global mean temperature into perpetuity, and any deviation from that is necessarily traced back to our tailpipes.
