IPCC has retreated from about a dozen alarmist claims on climate change

Climate change is an important subject. But the latest climb downs by the IPCC should really give everyone pause for thought

There's an excellent piece by Fred Singer, Professor Emeritus at the University of Virginia and director of the Science & Environmental Policy Project, to consider here on the latest, major retreats by the United Nations climate change body, the IPCC.

Highlights of Professor Singer's comments include:

1. "...the IPCC concedes for the first time that a fifteen-year-long period of insignificant warming (or perhaps even cooling) has occurred since 1998, despite a 7% rise in Carbon Dioxide concentration in the atmosphere. This is striking evidence that there is something wrong with the IPCC's climate models, which all predict a substantial warming in response to rising CO2."

2. "It is ironic that at the same time that predictions from 72(!) climate models and observations (from satellites and balloons) increasingly diverge, successive IPCC reports have expressed increasing certainty about human Influences on warming."

3. "Another interesting admission: The IPCC now has "low confidence" in predicting more frequent or more extreme droughts and tropical cyclones.  Thus, IPCC is specifically revoking its previous more alarmist claims."

4. "Among the many untrue claims, is one that asserts that post-1950 warming is "unprecedented." However, as shown by the Hadley [UK] record, it is reported as of about the same magnitude and rate as the 1910 - 1940 warming."

5. "We conclude that the current generation of global climate models is unable to make accurate projections of climate even 10 years ahead -- let alone the 100-year period that has been adopted by policy planners. The output of such models should therefore not be used to guide public-policy formulation until they have been validated and shown to have predictive value."

Again, there's no substitute for reading the original article, which I strongly recommend.
