> If there are no positive feedback loops, it would only warm up 1C maximum, no matter how much more CO2 we will emit.

GHG emissions are still increasing. If we assume that temperature increase is only linear in the amount of atmospheric GHGs, that means temperature will continue to increase, not remain flat.

Little known fact (I am still amazed how people don't know the mechanics of global warming...): CO2 effect in the atmosphere is logarithmic, increasing with concentration. That is because CO2 can only block one band of light, so at one point, you're approaching asymptotic effect. That's why we keep talking about "doubling of CO2", because it's a logarithmic function....

But yes, the temperature will increase slightly because of CO2 emissions. That triggers more warming due to feedback effects though, and those are hard to quantify, and more scary.
