There is a climate crisis. Deniers commonly have one or two facts that they claim show the scientists are wrong: the climate has always changed, carbon dioxide is only a tiny fraction of the atmosphere, and so on. They have an endless supply of supposed justifications for doing nothing.
Evidently the deniers imagine the climate scientists never thought of these objections, never investigated them. Well, they did.
[ The first part of this post is an article I’ll peddle around the traps. After that I provide some more detail, which is quite illuminating, especially a changing gif and a video. I was alerted to all this by Grist. ]
Perhaps in this season of heat and fire we might finally stop listening to climate denialists, the vast majority of whom are not scientists. Their only remaining argument is a grand conspiracy theory. Despite what you hear in mainstream discussion, the evidence supporting the conclusions of climate scientists is very strong, and just gets stronger.
Take, for example, the claim that global warming has stopped. This claim has been around for quite a few years now, but it got a bit of a boost recently when that well-known bastion of sober scientific analysis, Britain’s Daily Mail, interrupted its usual fare of tits, celebrity scandal and tits to misconstrue a UK Met Office report, claiming the report showed there has been no warming for 16 years. The claim is bunk, and a debunking is provided by the website The Carbon Brief, among others.
Meanwhile a careful analysis of the recent record of global warming that came out a year ago has made little or no impression on public discussion. It shows very simply and clearly that global warming has proceeded steadily for the past thirty years.
