No one can tell you that anymore than they could say who will win the FI FA championship next year. Any future projections are just pure fantasy.
How accurate is your local weatherman? He uses the same computer models to look at next week.
But I'll take a stab. In 1000 years the continent of Antartica will have shifted slightly off of the South Pole. With less land for ice to accumulate on, the overall temperature will be different from today. No need to worry about Co2. We will have depleted those resources long before that. Co2, with a shelf life between 5 to 100 years, will have been scrubbed out of the environment long before the 1000 year mark.
