Reminder: Historical Natural Warming Rates Dwarf Modern Climate Change

By Kenneth Richard on 20. June 2024

Greenland has not warmed (net) in the last 90 years.

From 80,000 to 20,000 years ago Greenland warmed by 10-15 Kelvin within a span of “a few decades” 24 times (Kypke and Ditlevsen 2024).

These abrupt warming periods occurred without concomitant CO2 concentration changes. And, of course, without human interference.

In contrast, Greenland has not warmed (net) since the 1930s, or since CO2 levels rose from 310 ppm to 425 ppm (Mikkelsen et al., 2018).

And Greenland warming is “not evident during the last two decades” either (Matsumura et al., 2021).
