The link is to an article on a presentation by the scientist Judith Curry. It is informative, but if you are new to the subject, may take some explanation. But, it does give a flavour of where Climate Science is today, which is far away from where Alarmists would have us believe.
The take away is the the uncertainties are so great and that areas with lack of knowledge so important, that the world should not be rushing into the Alarmists policy actions as promoted by the UN today.
Judith Curry is one of my science heroes. Very grounded and rigorous.
