We have geological evidence that since before the Mesozoic, at the very beginning of the Age of Dinosaurs, Earth was much warmer than today, and CO2 concentrations mainly due to warm sea temperatures were around 3000 Parts Per Million, (PPM), compared with the about 420 PPM today. Dr Chris Scotese, author of the Paleomap Project, says of those times, in the early Triassic, ~245 million years ago,

“Warm Temperate climates extended to the Poles.”
