Emergent constraints on TCR and ECS from historical warming in CMIP5 and CMIP6 models

By Nic Lewis

This is a brief comment on a new paper[i] by a mathematician in the Exeter Climate Systems group, Femke Nijsse, and two better known colleagues, Peter Cox and Mark Williamson. I note that Earth Systems Dynamics published the paper despite one of the two peer reviewers recommending against acceptance without further major revisions. But neither of the reviewers appear to have raised the issue that I focus on here. Continue reading

Advocacy research, incentives and the practice of science

by Judith Curry

There is a problem with the practice of science. Because of poor scientific practices, and improper incentives, few papers with useful scientific findings are published in leading journals. The problem appears to be growing due to funding for advocacy research.

Insights from Karl Popper: how to open the deadlocked climate debate

by Larry Kummer, from the Fabius Maximus website.

Many factors have frozen the public policy debate on climate change, but none more important than the disinterest of both sides in tests that might provide better evidence — and perhaps restart the discussion. Even worse, too little thought has been given to the criteria for validating climate science theories (aka their paradigm) and the models build upon them.

What would Charles Keeling think? Science in spite of politics

by Judith Curry

Perhaps my experience in studying the Earth, initially with few restrictions and later with increasingly sophisticated interaction with government sponsors and various planning committees, will provide a perspective on this great transition from science being primarily an intellectual pastime of private persons to its present status as a major contributor to the quality of human life and the prosperity of nations. – Charles Keeling

Words of wisdom from Charles Lyell

by Judith Curry

We are also told of general catastrophes and a succession of deluges, of the alternation of periods of repose and disorder, of the refrigeration of the globe, and of the sudden annihilation of whole races of animals and plants, and other hypotheses, in which we see the ancient spirit of speculation revived, and a desire manifested to cut, rather than patiently to untie, the Gordian knot. – Charles Lyell
