I live in Michigan. How many degrees warmer do you think it will be in 25 years? Keep in mind that we commonly go down to zero at night.

That article does not even have the word "degrees" in it. It doesn't answer my question of how many degrees warmer will it be in 25 years?

I understand it will certainly be less than 5.

well i believe 2-3 degrees average warming is the 'we might have some problems' (sea level rises displacing hundreds of millions) threashold and 6-8 degrees is the 'run for the hills' temperature (at which most of the ecosystems of the world breakdown unless the change happens _very_ slowly)

so if it is warm enough to not worry about the cold at Michigan, i think there may be other problems that need worrying about.

The other thing to note is that global warming is an average but the extremes get more extreme - ie, you could end up with the occasional night at -10.
