In 1974, Time Magazine blamed the cold polar vortex on global cooling.‘Scientists have found other indications of global cooling. For one thing there has been a noticeable expansion of the great belt of dry, high-altitude polar winds —the so-called circumpolar vortex—that sweep from west to east around the top and bottom of the world.’Forty years later, Time Magazine blames the cold polar vortex on global warming‘But not only does the cold spell not disprove climate change, it may well be that global warming could be making the occasional bout of extreme cold weather in the U.S. even more likely. Right now much of the U.S. is in the grip of a polar vortex, which is pretty much what it sounds like: a whirlwind of extremely cold, extremely dense air that forms near the poles.’
For the ecochondriacs to convince you of anthropogenic global warming, they have to assume you're either stupid or have no memory. It isn't reasonable to claim the same weather event in different decades is caused by opposite climate change scares.
As I've pointed out in the past, Earth's climate has always changed. That's the only constant in recorded and scientifically reconstructed weather history. So, you can't just call your cause "climate change" because that's a given. You must claim anthropogenic warming or cooling and prove your case. The current movement hasn't done that, and they're panicking as their case is further undermined by mounting evidence against their claims of anthropogenic global warming.
