Hole In The Ozone Layer Smallest In 29 Years (weather.com)
An anonymous reader quotes the Weather Channel:
The hole in the ozone layer over Antarctica is the smallest it's been since 1988, NASA said. According to a press release, the hole in the Earth's ozone layer is 1.3 million square miles smaller than last year and 3.3 million square miles smaller than 2015... This year, the hole grew to 7.6 million square miles. NASA and NOAA scientists said warmer temperatures and a stormier upper atmosphere helped keep damaging chemicals chlorine and bromine from eating ozone from the layer that protects the Earth's surface from harmful ultraviolet rays... The hole that hovers over Antarctica has been slowly recovering, scientists say, due to an international ban on harmful chemicals that were previously used in refrigerants and aerosols.
The hole was its largest in 2000 and measured 11.5 million square miles. Although recovery is underway, the size of the hole remains large compared to the 1980s, when the hole was first detected, NASA noted. And while there has been significant healing of the ozone layer in recent years, some scientists say full healing is a slow process and will not occur until sometime in the 22nd century, Yale Environment 360 reports. Others expect the Antarctic ozone hole to recover back to 1980 levels around 2070, NASA said.

And, Reagan got snookered by Tip O'Neill. Reagan would get his tax cuts and O'Neill would cut the appropriations. O'Neill never followed through and knew that his caucus didn't give a flying rat's ass what O'Neill promised Reagan, it was an empty promise.
Reagan at least knew that cutting taxes would increase the deficit and hence wanted the appropriations cut. When that didn't happen, his administration discovered voodoo economics. The economy was fueled by deficit spending and the beginnings of the tech revolution. Also the business cycle recovered from Carter's years.
The current lot of Republicans never learned that lesson. They somehow believe that since Kennedy cut taxes and increased tax receipts as a result, they can do the same thing. When taxes are that high (over 70% in some cases), that works. When taxes are relatively low like now, it doesn't work. They figure if they give companies and rich people more money, they'll invest in more business. What they leave out is that demand hasn't changed. Businessmen and rich people aren't stupid, they won't invest to meet non-existent demand.
Republicans also feel nostalgia for Bill Clinton and the boom economy of the 1990s. That happened because of the tech boom and the race to fix Y2K. Once that was over, in approx. April-May of 2000, the economy started tanking.
Believing a lie is never a recipe for success.
Fixing the ozone hole (freon) by replacing freon with hydrofluorcarbons was a big mistake, they are far more potent greenhouse gases. Don't pat humans on the back yet, we're not that smart. Ref: https://phys.org/news/2017-11-... Citation provided.
Why guess when you can know? Measure!
A convenient but false narrative. Convenient because it allows people to rationalize their support of the party of racists and bigots.
What has happened is that the center of politics has shifted to the right, so that the Dems are now where the Republicans were a few years ago and the Republicans are far to the right.
The real "Libtards" are the Libertarians!
