Rye Catcher
People believe the world we live in today is normal. It's not. It's actually quite rare. The world we live in is considered to be an ice house planet. Our modern day ice house planet is characterized by bi-polar glaciation, glacial/interglacial cycles and a high latitudinal thermal gradient between the polar regions and the equators. No previous record for bi-polar glaciation exists in the geologic record.
2.7 million years ago we transitioned from a greenhouse planet to an ice house planet. Greenhouse planets are characterized by a lack of bi-polar glaciation and have a low latitudinal thermal gradient between the polar regions and the equator.
As you scroll through this sequence note the lack of ice in the northern hemisphere - except for the present day ice house planet we live in today of course.
Sequences were mapped using the Mollweide projection, and, in all cases, are by Ron Blakey.
