It's also worth noting that paleoclimate proxies show that a concentration of CO2 at 400ppm is unprecedented in perhaps over 5,000,000 years. The temperatures we are now seeing may have occurred during the warmest part of the Holocene, but the climate is like a supertanker. It is imbued with tremendous momentum, so if we magically stopped all anthropogenic carbon emissions today, the concentration would keep going up for decades, and the temperature increase and ice sheet wastage would keep going on for millennia.
