I like narrowing of uncertainty”. The question is what level of narrowing will I need in order to know that I want to take action? Some of the climate science sure resembles a medieval witch kitchen. Assumptions derived from assumptions that have been pulled from again more assumptions. How do i know the exact temperature in London in 1600 from a snow core in Greenland? Can we derive temperatures to the tenth of a degree from a snow sample of today? We cant even predict whole degrees. I would be a lot more comfortable with all this if the scientists actually lived up to those inconsistencies. The consequences are too important for the debate about this to be muted.
A common skeptic refrain is that “the science isn’t settled”, meaning there are still uncertainties in climate science and therefore action to cut CO2 emissions is premature.
