I'm so glad you asked If we were to continue CO2 emissions to an atmospheric concentration of 800 ppm of CO2, the IPCC formula translates into an ultimate average temperature change of 4.5 C (8.2 F) with a likely range between 3 C (5.4 F) and 6.8 C (12.3 F). The world has not seen this level of CO2 concentrations for some 50 million years, when crocodiles and palm trees thrived in the Arctic Circle, Greenland and Antarctica were ice-free, and sea levels were hundreds of feet higher than today. pbs.org NASA even spent some of my money to make cartoons just for you. livescience.com Don't forget there is a lag time; it's not an on-off switch. Antarctica's ice will still take a few thousand years to totally melt.
