I'm sure many of my readers have seen this 1990 documentary on the greenhouse effect - sort of an early version of the Great Global Warming Swindle - but it's the first time I've seen it.
I was struck firstly by how shifty-eyed Tom Wigley and John Mitchell come across, particularly when Wigley is asked about funding at around 46 mins. If you don't want to invest the time in the full video, this is the excerpt to watch.
Then there is the clear statement by the late Reginald Newell that he had his funding cut because of he had published a paper that undermined the greenhouse theory.
It's all rather amazing how little the debate has moved on in twenty years.
