The world has been warming since the last Glacial period. The ice peaked about 20,000 years ago, when the average temperature was 3.8 degrees C colder than today. 120,000 years ago, at the last Climatic Optimum, the world averaged 1. 5 degrees C warmer than it is today. In response to the normal orbital forcings, we expect natural warming for another 1200 to 12,000 years, and another Climatic Optimum temperature between those two bounds.
When the Climatic Optimum between Glacials is reached, these are the normal expectations:
1) A global temperature peak at least 1.5 to 2.5 degrees warmer than today, based on the last 262 Glacials recorded in the fossil records.
2) The absence of ice at the poles, and the emergence of the Antarctic continent as a sub-temperate landmass with vegetation.
3) Higher sea levels as discussed at length in this Forum.
4) Generally warmer temperatures, higher levels of atmospheric carbon dioxide as a result, enhanced plant growth on the remaining land masses.
5) The above changes will collectively kickstart yet another cooling period, and the glacial land masses will again advance across all the continents. Our species is likely to evolve some more as it did in the last Glacial, when we killed/interbred/outcompeted/ate the Neanderthals and the Denisovans.
That's the normal and even boring expectations. The idiocy is entirely in believing that the activities of mankind have any appreciable or significant impact on these entirely normal temperature variations.
