Temperature increase by year 2100?
If governmental policies do not change, what will be the increase in global average surface temperature in the year 2100 relative to the pre-industrial era (1750)?
Not more than 2°C
More than 2°C, but not more than 3°C
More than 3°C, but not more than 4°C
More than 4°C, but not more than 5°C
More than 5°C
Note that this question asks about temperature at a particular moment in time, without reference to whether or not an equilibrium in temperature change has been reached.
Please comment or vote on the usefulness of this question. Thanks.

Curious as to why a question about expected temperature rise this century was not included [in Q4-2013 poll].
VP response: We expect to run this question in an upcoming poll.
