Show me how 1 degree of warming can melt Greenland or Antarctic ice, for example. You can't. Not even the scientists of the side you favor make the claim it can. I degree of warming per century will not cause a crisis.
Think of a degree of warming in the perspective of weather outside your door. Not much, right? How quick can it happen? Now think of that globally over a century. Still scared?
Not a valid comparison. One degree increase in worldwide average is not the same as one degree temperature change locally. And the change isn't the problem, the rate of accelerating change is. Next century it won't be one degree, it could be 2 to 4. Then who knows the century after that.
Too fast for life to adapt to that change.
Seems to me trying to predict climate to the next century is a bit over the top. I doubt we'll be spewing as much carbon as we do now, hell we may have run out of critical resources and had a major die back.
Predicting climate may prove easier than predicting weather. Chaotic systems like economics or the motion of a flock of birds can be predicted, if we know the variables. That's what we are still learning.

I thought the danger point was 2 degrees warming. If the prediction really is just 1 deg over this century, then I think we're not doing too bad, not as much of a worry.
1 degree is a huge amount of extra energy to be trapped in our atmosphere. I read somewhere that if we took all our nuclear weapons and detonated them, the heat would raise the Gulf of Mexico by half a degree. Now, imagine 1 degree across the whole planet.

Certainly not worth totally screwing up our economy over. Still, there are other good reasons to stop spewing carbon, from air pollution from coal, to the hazards of extracting and shipping gas and oil, to societal problems from dependency on the automobile and so on.
It always comes to that, eh? No one wants to do anything because 'the economy'. I'm glad that for the first time this year, carbon output diverged from economic output. That shows us that we can affect CO2 emissions and not affect the economy. So that excuse is officially dead.
