Re: Not exactly slowly
I was referring to planetary average temperature.
Greenland is an outlier that has radical temperature changes based mostly on tropical and Arctic ocean currents.
Thank you for the excellent charts.
I have not seen them before.
The Greenland ice cores are a proxy for average temps of the Earth. If average temps in Greenland rise 18 C it’s pretty much a certainty they’ve risen quite a bit everywhere else though not necessarily the same amount.
