@ John Hughes Re: Emeritus
Maybe at work, but not bothering to keep up with the research.
What has happened in the past 10 years is that the discrepancies between what's observed and what's predicted have become much stronger.
That's simply rubbish.
He was being polite, as a proper scientist he probably shudders at the thought of the fraudsters at UEA and the rest of the climate scammers.
As he points out, CO2 isnt the issue, its all the other stuff you get from burning coal and other fossil fuels.
Diesel, less CO2 per KM but many thousands of deaths from all the other crap is just one example.
Bottom line, pollution is bad (particulates, NOx etc) whilst CO2 is plant food.
