Factcheck: What Greenland ice cores say about past and present climate change

ZEKE HAUSFATHER  Carbon Brief, Clear on Climate

A misleading graph purporting to show that past changes in Greenland’s temperatures dwarf modern climate change has been circling the internet since at least 2010.

Based on an early Greenland ice core record produced back in 1997, versions of the graph have, variously, mislabeled the x-axis, excluded the modern observational temperature record and conflated a single location in Greenland with the whole world.
