“Global Warming” aka “Climate Change” aka “Climate Disruption” aka “Global Weirding” is the virtue-signalling religion of our time.
With the decline of religion, some people need a moral signal to show that they’re good.
“Global warming” is particularly good because they don’t actually have to do anything. They don’t have to cure lepers, or feed the hungry. All they have to do is yell that the planet is warming up.
Until they find another way of signalling virtue, we’re stuck with this one!
