New Paper: Mammals Thrived and Diversified With ~2000-4000 ppm CO2, 20°C Warmer Oceans Than Today

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). Image Source: Voosen, 2019 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 … Continue reading New Paper: Mammals Thrived and Diversified With ~2000-4000 ppm CO2, 20°C Warmer Oceans Than Today
