Will atmospheric CO2 double by year 2100?

FULL QUESTION:
If governmental policies do not change, what is the likelihood that CO2 concentration in the atmosphere in the year 2100 will be at least double that of the pre-industrial era (1750)?

ANSWER OPTIONS:
Very unlikely (<10%)
Unlikely (<33%)
About as likely as not (33-66%)
Likely (>66%)
Very likely (>90%)

NOTES:
Atmospheric CO2 concentration was about 280 ppm in 1750, and is about 400 ppm today. Note that the questions in this poll refer to CO2, not CO2e.

        I suspect that most Americans will think this implies that changes to the policies of the US government can solve this problem, but it cannot be solved without international agreement. This means that the US government has to change its "me first" philosophy!

        This is a good question, but 2100 is probably too far out - rather go for 2050
