The global average temperature was 2 to 3 degrees C warmer than today. The ocean circulation was vastly changed and the Atlantic Ocean cooled.
Read dubya....the arctic was at least 11 degrees warmer. That doesn't translate to 11 degrees all over the earth and the ocean circulation was practically identical. One only need look at the positions of the land masses at the time to see that.
dumbdumb is a SUPER DUPER Genius, he doesn't read anything...he just believes. Hmmmm, that sounds religious zeolot like doesn't it.
Why don't you read? Why is an arctic being warmer relative to the rest of the Earth hard to understand? Where has it been warming at the fastest rate on Earth?
When the circum-equatorial current ended, it isolated the Atlantic Ocean and it cooled. You have Greenland getting an ice sheet, the start of arctic sea ice, the creation of the modern thermohaline circulation, the modern Gulf Stream forming, the Mediterranean Sea drying up at the beginning, global sea levels 25 meters higher and major changes in flora to a cooler, drier and seasonal world. The tropical rainforests retreated to just around the equator and savannahs, grasslands and deserts spread around the world. The 2.7 million year changes during the Pliocene is what ushered in the Ice Age Pleistocene.
