Nineteen years ago, on this day, March 8th, 2007,
Great Global Warming Swindle broadcast on Channel 4
http://en.wikipedia.org/wiki/The_Great_Global_Warming_Swindle

The amount of carbon dioxide in the air was roughly 382ppm. As of 2026 it is 428ppm, but check here for daily measures.
The broader context was that climate change had come alive as an issue in the summer of 2006 especially in the UK, thanks to various factors, including “Camp to Climate Action,” (which I was involved in), and Al Gore’s “An Inconvenient Truth. Therefore the backlash would have to begin.
The specific context was that the idiots who made the documentary had form. They had produced something in the late 90s called Against Nature that said, in effect, “Hitler was vegetarian, therefore vegetarians are at least Nazi-adjacent.”
What I think we can learn from this is that mud and shit will be flung by opponents of action towards stopping us killing ourselves more quickly than we otherwise might. This is especially the case if “stopping our killing ourselves quickly” involves cutting into the profits of rich white people and the so-called liberties of rich white people. It’s not just the rich, of course, I’m being tabloid here.
What happened next
The Swindle enabled middle class people who didn’t want to take a stand and change anything to say “Oh, well, there’s still doubt. Scientists are still not sure.” Blah, blah, blah.
What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.
