Here’s his conclusion: So where do the 1934/1998/2010 warm years rank in the long-term list of warm years?
It also reflects regional Greenland warming, not global warming.
This is his Fig 5: Easterbrook plots the temperature data from the GISP2 core, as archived here. However, the GISP2 “present” follows a common paleoclimate convention and is actually 1950.
The first data point in the file is at 95 years BP.
It’s clear there is a calibration issue between the long term proxy (based on ∂O measurement) and recent direct measurement of temperatures on the Greenland ice sheet.
How that might be resolved is an interesting question, but not directly relevant to the point at issue — which is what Don Easterbrook is trying to show.
Most of the last 10,000 years were warmer Even if the warming were as big as the IPCC imagines, it would not be as dangerous as Mr. After all, recent research suggests that some 9,100 of the past 10,500 years were warmer than the present by up to 3 Celsius degrees: yet here we all are.
