"A well-documented record of global temperature over the past 65 million years shows that we have been in a major cooling period since the Eocene Thermal Maximum 50 million years ago.
The Earth was an average 16C warmer then, with most of the increased warmth at the higher latitudes.
The entire planet, including the Arctic and Antarctica were ice-free and the land there was covered in forest.
The ancestors of every species on Earth today survived through what may have been the warmest time in the history of life.
It makes one wonder about dire predictions that even a +2 degrees C. rise in temperature from pre-industrial times would cause mass extinctions and the destruction of civilization.
Glaciers began to form in Antarctica 30 million years ago and in the northern hemisphere 3 million years ago.
Today, even in this interglacial period of the Pleistocene Ice Age, we are experiencing one of the coldest climates in the Earth's history"
