If you make predictions sufficiently far into the future, there's no way to refute them or have any rational debate. The green body has been using this technique for decades, making wild predictions about the future that are impossible to refute at the time.
Unfortunately for them, the internet has made it easy to look back and laugh at their predictions. Take this article in the Guardian from August 1999, which reports on a study by the University of East Anglia's climatic research unit. Yes, that's the same University of East Anglia the climategate emails were leaked from. It predicts that:
By 2020, visitors to the Costa del Sol could risk contracting malaria as global warming brings more frequent heatwaves, making the country a suitable habitat for malaria-bearing mosquitoes
Hmm, I haven't heard about any malaria outbreaks in Spain.
the eastern Mediterranean will be as hot as the Sahara desert, flash floods will swamp parts of the American coastline and there will be almost no snow in the Alps.
Um...nope.
Meanwhile, some islands in the Maldives could disappear as they are submerged by rising sea levels.
Let me check. No, the Maldives are still there.
Areas such as the Mediterranean - a popular destination for British tourists - could become unbearable during the traditional summer holiday season. As temperatures begin to soar, many tourists will stay away.
No, the Mediterranean is still a popular destinations for British tourists, and I haven't heard anyone saying the temperatures are unbearable.
Winter tourism will be affected in the Alps and other European skiing destinations from the impact of less snowfall and shorter skiing seasons
My brother just got back from a skiing holiday in the Alps. He had a great time. You know, because it was all still covered in snow. If it wasn't covered in snow his skiing holiday would have been a bit shit.
So, that was all bullshit from the "scientists" at the University of East Anglia. Of course, they're not actually scientists, just Marxists using environmentalism as a front to push a socialist agenda and increase immigration for "climate refuges." Alexandria Ocasio-Cortez’s chief of staff, Saikat Chakrabart, gave the game away when he said about the Green New Deal, "The interesting thing about the Green New Deal is it wasn’t originally a climate thing at all. Do you guys think of it as a climate thing? Because we really think of it as a how-do-you-change-the-entire-economy thing." It would apparently advance "social, economic, racial, regional and gender-based justice and equality and cooperative and public ownership." Once again, we see that environmentalism is just socialism by the back door.
Anyway, I'll see you boys in 2050 when we can look back at this article and have a good laugh. Assuming we're not living in some sort of Marxist nightmare by then.
