Douglas Hoyt
Solar Physicist and Climatologist
Starting in 1997, we created a scorecard to see how climate model predictions were matching observations. The picture is not pretty with most of the predictions being wrong in magnitude and often in sign. [Hoyt gives each prediction a 'yes-no-undetermined' score. The current score in this case is 1-27-4]

Geologist
Personal beliefs on climate change and rising sea levels should be delayed until just one of the many predictions made since 1985 on the basis of carbon additions to the atmosphere comes true.

John Maunder
Climatologist
Leading scientists, including some senior IPCC representatives, acknowledge that today's computer models cannot predict climate. Consistent with this, and despite computer projections of temperature rises, there has been no net global warming since 1998.
