From what I understand, all of the planets are slightly warming — even Pluto, in lock-step with Earth which means our Sun is just going through a phase. But you sure can make a lot of money scaring people. The government of the Earth are primarily worthless, and at worse, I wonder why we even bother. But with crisis like these that they make up, they can justify their being there. They love making up huge, unfixable problems, the climate, closing the IQ gaps, etc because there is nothing an individual can do. So people look to the worthless, cocaine-addled useless politicians for “help.”
Back around 2008, Fred Thompson wrote an article about that. IIRC, the title is "Plutonic Warming".
