So Easterbrook is still pushing his false GISP2 ice core graph.

It’s funny that despite all the skeptics whining about chartmanship and graphs they have been totally unable to stop the likes of Easterbrook pushing this zombie argument. Are we to believe none of them spot the problem?
The issue here is that the GISP2 ice core data ends in 1855. To bring it to the present day so that he can compare the present day to the rest of the holocene, Easterbrook adds just 0.5C warming to the end of the graph.
What staggering is that he’s even supplied 20th century greenland temperature graphs in figure 2 which show about 3C warming since 1855. Not 0.5C as he’s plotted. His present day is thus more than 2C too cool.
If he plotted that extra warming he’d find his words coming back to haunt him as GISP2 actually conrifmed Marcott’s conclusion that “Current global temperatures of the past decade … are warmer than during ~75% of the Holocene temperature history.”
