What was the Climate like during the Emmian (last interglacial period) 130,000 - 115,000 years ago? It is said that back then the global average temperature was 1 to 2 degrees Celsius (1.8 to 3.6 Fahrenheit) warmer than the present day, and global sea levels were 6 to 9 meters (20 to 30 feet) higher than today, meaning that for instance Scandinavia was an Island and the Western Siberian plain was a shallow sea, however Greenland still had some glaciers during that time, meaning at most Greenland contributed 2 m (6.6 feet) and another 1 m (3.3 feet) was caused by thermal expansion which means the rest came from Antarctica. But as far as actual climactic differences those details are hard to come by, I did read that the prairie-forest boundary of the great plains was further west near Lubbock, TX compared today at Dallas, TX. If anyone has any more info it would be interesting as it could be a foreshadowing as to what we can expect with current climate change projections.

Donβt know much about this but would be interesting to see what climates were like then

That suggests the 0Β°C winter isotherm was further south into the US than it is today. The Sahara and East Asia also look colder than present in winter. However, it appears the Arctic had much warmer summer temperatures.

If I understand correctly, the earth was tilted in such a way that the northern hemisphere was closest to the sun in the summer and furthest away in the winter, which is the opposite of what we have right now, which would explain the extreme seasonal differences.
