Policies to reduce carbon dioxide emissions to minimize the effects of climate change should be guided by the best available science.
A new research paper from The Heritage Foundation provides compelling evidence—as indicated in the chart below—that warming in the past 50 years or so has been overestimated by most computer models when compared to temperature observations by thermometer.
The Heritage Foundation’s Backgrounder paper, written by the first author of this commentary, is titled “Global Warming: Observations vs. Climate Models.” (The Daily Signal is Heritage’s news outlet.)
A vocal minority of scientists often criticizes work such as this paper because their careers depend upon continued climate alarmism.
For example, NASA’s Gavin Schmidt, a mathematician by training who now oversees a subset of the climate models at the Goddard Institute…
