Our first official +1.5C year. Well done everyone! It's amazing how good we are at f@$king everything up., page-277

Doubt if they really know what is going on and why - maybe just Mr Climate doing its thing?

Ice cores (from 800,000 years before present)

Even longer term records exist for few sites: the recent Antarctic EPICA core reaches 800 kyr; many others reach more than 100,000 years. The EPICA core covers eight glacial/interglacial cycles. The NGRIP core from Greenland stretches back more than 100 kyr, with 5 kyr in the Eemian interglacial. Whilst the large-scale signals from the cores are clear, there are problems interpreting the detail, and connecting the isotopic variation to the temperature signal.
