The increasing wetness really only occurred in the northern subtropics. Although the tropics cooled from the Triassic to the Jurassic, the average global temperature rose due to increasing carbon dioxide. Thus, referring to the Triassic as warm and the Jurassic as wet is an oversimplification of the geological evidence and palaeoclimate model simulations. ..."
