A new book by Oppenheimer, Oreskes et al. entitled ‘Discerning Experts: The Practices of Scientific Assessment for Environmental Policy‘ make a case against consensus seeking in climate science assessments.

How valid conclusions often lay hidden within research reports, masked by plausible but unjustified conclusions reached in those reports.  And how the IPCC institutionalizes such masking errors in climate science.

Part III: is there any signal of global warming in landfalling hurricanes and their impacts?

Chapter 6 – Temperature Changes in the United States of the U.S. Global Change Research Program’s recently published Climate Science Special Report (2017) clearly shows and discusses, under the heading of “6.1.2 Temperature Extremes”, how temperature extremes for the contiguous United States have become more moderate over the last 118 years, with the coldest daily temperatures warming and the warmest daily temperatures cooling. In other words, temperature-extreme-related climate in the United States has improved.

We’ve long been fond of showing the satellite evidence for planetary greening caused by increasing carbon dioxide, particularly the work of Zhu et al.(2016):

On the terminations of Ice Ages.

Summary: The IPCC expresses virtual certainty that a glaciation is not possible for the next 50 Kyr if CO₂levels remain above 300 ppm. It is the long interglacial hypothesis. Analysis of interglacials of the past 800 Kyr shows they depend on obliquity-linked summer energy, ice-volume, and eccentricity, and they end at glacial inception after ~ 6000 years of Neoglaciation-type temperature decline. The lag between orbital forcing and ice volume change indicates the orbital threshold for glacial inception is crossed thousands of years before glacial inception, and the Holocene went through that threshold long ago. In the absence of sufficient anthropogenic forcing glacial inception should take place in 1500-2500 years. The long interglacial hypothesis rests on the wrong astronomical parameter, high-equilibrium climate sensitivity to CO₂, and uncertain model predictions of very long-tailed CO₂decay. It is not possible to determine at present if…
