Don Easterbrook Projection vs Observations (zoomed)

Comparison of "skeptic" geologist Don Easterbrook's projections of global cooling from his presentation at the 2008 American Geophysical Union annual meeting (green and blue) with observational data from the NASA GISS land-ocean dataset (red), focusing on the time period 1995 to 2015.  Easterbrook's temperature projections can be compared directly to the measurements in the overlapping period 2000 to 2010, where the IPCC and virtually all climate scientists have predicted continued warming.  Easterbrook's projections are inaccurate because he doesn't use a physics-based approach but simply relies on correlations from past climate patterns and largely ignores the now-dominant effect of human greenhouse gas emissions.  See also the graphic showing the longer period 1900 to 2100.
