"The risk of extinction from global warming do to human emitted CO2 is apparently less then the risk of extinction from celestial impact."

Extinction is just an upper bound. There are many gradations from "no change at all" to "extinction". I am not sure how you surmise that celestial impact has a higher probability, though.

The most likely benign scenarios are things like having to relocate the majority of the population, developing new food crops and such. Now the time scale is on the order of a century or so, but that just spreads the cost over time. Building entire major cities or expanding the infrastructure of existing small towns is a huge cost. Not to mention losing the infrastructure of the existing cities.
