At the end of the Cretaceous Period, Antarctica was about six hundred miles farther north than it is now. That is about the latitude of Tierra del Fuego. That island is devoid of any rain forests today. The Late Cretaceous atmosphere must have had far more green house gasses than anything humans have experienced so far. However, if we continue to elect presidents who are as clueless as the leaders of the USA and Australia are today, that will change in a few more centuries.
