Climate science’s ‘masking bias’ problem

Posted on June 21, 2019 by curryja | 117 comments

by Judith Curry

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.

Rebelling against the Extinction Rebellion

Posted on May 4, 2019 by curryja | 168 comments

by Larry Kummer

The Extinction Rebellion and the Green New Deal arouse fears of extinction for other species, and humanity. Only the complicit silence of climate scientists makes this possible. Compare the alarmists’ claims with what scientists said in the IPCC’s Fifth Assessment Report (AR5). Too bad that journalists don’t.

What’s the worst case? A possibilistic approach

Posted on March 27, 2019 by curryja | 141 comments

by Judith Curry

Are all of the ‘worst-case’ climate scenarios and outcomes described in assessment reports, journal publications and the media plausible? Are some of these outcomes impossible? On the other hand, are there unexplored worst-case scenarios that we have missed, that could turn out to be real outcomes? Are there too many unknowns for us to have confidence that we have credibly identified the worst case? What threshold of plausibility or credibility should be used when assessing these extreme scenarios for policy making and risk management?

Why I don’t ‘believe’ in ‘science’

Posted on March 26, 2019 by curryja | 153 comments

by Judith Curry

” ‘I believe in science’ is an homage given to science by people who generally don’t understand much about it. Science is used here not to describe specific methods or theories, but to provide a badge of tribal identity. Which serves, ironically, to demonstrate a lack of interest in the guiding principles of actual science.” – Robert Tracinski

Four fronts for climate policy

Posted on March 25, 2019 by curryja | 102 comments

by Judith Curry

“For decades, scientists and policymakers have framed the climate-policy debate in a simple way: scientists analyse long-term goals, and policymakers pretend to honour them. Those days are over. Serious climate policy must focus more on the near-term and on feasibility.” – Y. Xu, V. Ramanathan, D. Victor
