Posted on October 27, 2016 by | 98 comments

by Judith Curry

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

Posted on January 28, 2016 by | 654 comments

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
