4.5 Degrees

The good news is that according to the latest IPCC report, if we enact aggressive emissions limits now, we could hold the warming to 2°C. That's only HALF an ice age unit, which is probably no big deal.

So, if -1 IAU is a block of ice and 0 IAU is modern times, then +1 IAU is the world on fire. Clearly, the solution is to get a giant block of ice from Halley's Comet every so often. That will solve "Global Warming"™© once and for all. Or maybe we need to resurrect "Global Cooling" and "Nuclear Winter" from the 1970s. That will even things out.

That's 1 IAU within 100 years. Temperature increases keep going after that...there's lots of interia in the system just from simple things like the large specific heat of water in the oceans.

Note that the impact of CO2 concetration on warming is logarithmic. the key parameter is "climate sensitivity": how many degrees C warming you get per *doubling* in CO2 concentration.
