 It doesn't because typically also what we're seeing now with anthropogenic climate change is that there's a polar amplification. So if you have a warming, the higher latitudes tend to warm quite a bit faster than the lower latitudes. So a warming of that much in Greenland would not be a warming of 8 degrees on the globe. But there are other recorded archives from, for example, ocean sediment cores and lake sediment cores that also show these signals here.
