It's nice to see something positive!

Quoteprojected to recover "sometime around 2070."

Yay! That's the part I was wondering about - are we slowing the damage or reversing it? It appears we are actually reversing it :-)

I remember when the hole in the ozone layer was a big deal in the 1980s.  Cars were updated with new air conditioner systems and hair spray propellant was changed. 

Why?  People listened to scientists who said "By the way, this needs to change."

Now, scientists say we have an issue with global warming and we need to stop putting greenhouse gases in the air.  Except today, instead of everyone listening to science, people argue with scientists. 

Hell, there is a group of people who genuinely believe the earth is flat.  It's...stunning, really.

This is basically the argument that George Schultz used to trot out, with a wrinkle.

He said that there was a lot less scientific consensus on the ozone problem than there is about climate change, so some reputable scientists didn't feel there was a major problem

Quote"I had two private meetings a week with President Reagan," said George P. Shultz, the former president's secretary of state. "We talked about it. He became convinced that it was a real big problem."

But not all scientists were convinced, and their uncertainty was holding up action.

"And then he did something that nobody ever does anymore," Shultz said. "He went to the scientists who didn't agree and put his arm around them and said, 'We respect you, but you do agree that if it happens it's a catastrophe, so let's take out an insurance policy.'"

The scientists couldn't argue with that.

"That didn't get them on our side," Shultz said, "but it got them off our back."
