Breaking news: the UN’s Intergovernmental Panel on Climate Change (IPCC) admits assessments nonsense.
That’s not quite true. The IPCC made the admission but it wasn’t breaking news. In fact, it wasn’t news at all. Continue reading

H. Leighton Steward: Will They Come?
Concerned with statements made by current NASA officials that the science of climate change is settled and that it is now certain that man-made CO2 will result in catastrophic global warming, a group of former NASA scientists have formed a group to review the basis of such statements. Calling themselves the “Right Climate Stuff” team, they have begun inviting experts from both sides of the almost non-existent public debate concerning the human impact on global climate change to present their data and conclusions. But will they come? Continue reading
C3: Climate Modeling Failure: IPCC’s Model Prediction Of Extreme Precipitation Events Found To Be Wrong
As almost all scientists now admit, the IPCC’s climate modeling failures continue to persist with little hope of better accuracy in near future – latest failure example is the extreme precipitation prediction that Swiss scientists found to be without merit Continue reading

Predictions by climate models are flawed, says invited speaker at Sandia
Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, told about 70 Sandia researchers in June that too much is being made of climate change by researchers seeking government funding. He said their data and their methods did not support their claims. Continue reading

New Paper “Parameterization Of Instantaneous Global Horizontal Irradiance At The Surface. Part II: Cloudy-Sky Component” By Sun Et Al 2012
There is yet another paper that documents the lack of skill in multi-decadal global climate models to skillfully predict climate conditions in the coming years. This paper involves the question of accuracy lost when radiation parameterizations are used at time intervals that are long compared to other physical processes in the models. Continue reading
James D. Agresti: Will global warming flood the coasts of the United States?
Two new studies are predicting accelerated sea-level rises on the East and West coasts of the United States, primarily due to global warming. Major media outlets—and in some ways the studies themselves—have painted a distorted picture of past, current, and future sea levels. In fact, the studies actually conflict with each other, a crucial fact that has gone unreported in news reports that have mentioned both of the studies. Continue reading

Hockey Schtick: Settled science update: Climate models make ‘very large’ errors in determining solar radiation at Earth’s surface, ‘ignore the effect of clouds’
A paper published today in the Journal of Geophysical Research finds that current global climate models make “very large” errors in determining solar radiation at the surface of the Earth “due to ignoring the effects of clouds.” Continue reading
Pierre Gosselin: Heimholtz Centre for Ocean Research Climate Projections Turn Out To Be Entirely Wrong – Not A Dry Summer Since 2003!
Now that the inconvenient results of earlier models are coming in, the once esteemed German climate institutes, which we were not allowed to question, are sitting neck-deep in embarrassment. Continue reading
Hockey Schtick: New paper shows IPCC models exaggerate water vapor feedback
The whole case for catastrophic anthropogenic global warming is founded on agressive positive feedback from water vapor acting as a multiplier of the small warming possible from added atmospheric carbon dioxide. Experimentally a doubling of atmospheric carbon dioxide should deliver ~1.2°C warming, which the IPCC inflates with +60% feedback like this: 1.2 * 1/(1-0.6) to yield their median case of +3°C. We have long suspected the IPCC is correct about the magnitude of the feedback but wrong about the sign of that feedback. Continue reading

No evidence of polar warming during penultimate interglacial
The Atlantic Meridional Overturning Circulation (AMOC), driven by temperature and salinity gradients, is an important component of the climate system; it transfers an enormous amount of heat via ocean currents and atmospheric circulation to high northern latitudes and hence has bearing on climate in the region.

David Henderson: Robert Murphy on Global Warming
Robert Murphy has a first-rate piece on global warming in which he covers some important new ground. First, here’s ground he and I (in a post on his earlier article) have already covered but he says it particularly well: Continue reading

Robert Murphy: Nordhaus, Tol, and Climate-Change Economics: Turning Around the Conventional Wisdom
“The scientific modeling of climate change, and its possible impacts on human welfare, are very technical…. When experts try to summarize the fields for the layperson, they sometimes present matters in misleading ways, however inadvertent. William Nordhaus’s treatment of the economics literature, and RealClimate’s discussion of the accuracy of climate models’ temperature predictions, are good examples.” Continue reading
For 27 Years NASA’s Climate Model Warming Predictions Wrong – Odds Are 1 In 134 Million of Being This Wrong
In a previous ‘C3′ article, it was well documented how badly the NASA-James Hansen climate model predictions have performed versus reality. Hansen long ago had predicted that if human CO2 emissions continued in a manner of ‘business-as-usual’ there would result exceptional, accelerating global warming. Continue reading

Global Warming Fosters High-Latitude Cooling?
In a study published in Environmental Research Letters, Cohen et al. (2012) note that over the last four decades Arctic temperatures have warmed at nearly double the global rate, citing Solomon et al. (2007) and Screen and Simmonds (2010); and they state that “coupled climate models attribute much of this warming to rapid increases in greenhouse gases and project the strongest warming across the extratropical Northern Hemisphere during boreal winter due to ‘winter (or Arctic) amplification’,” citing Holland and Bitz (2003), Hansen and Nazarenko (2004), Alexeev et al. (2005) and Langen and Alexeev (2007). Continue reading
