Ozone hole trend
« on: July 10, 2019, 01:27:35 AM »
I am having difficulty assessing the overall trend in ozone hole size. On the one hand the hole was predicted to get smaller, on the other hand it was record large in 2015.

Online graphics that I have was hoping to compare with recent figures tend to cut off around 2014.

Is there a good page out there assessing the trend? Or a recent animated graphic incorporating the past 30 years or so up to now?

In the 1980s, the World Acted to Save the Ozone Layer. Here's Why the Fight Against Climate Change Is Different

Quote
The discovery of the ozone hole was sometimes called a “focusing event” — an event that focuses public attention on a particular problem. The effects of climate change are beginning to be more and more perceptible to different people, but they are not yet as obvious as the ozone hole. It might have to be that a big piece of Greenland falls into the sea and sea levels rise by a foot — that would get us thinking about climate change. But the slow nature of climate change doesn’t lend itself to that kind of shock value.

This particular summit just doesn’t seem like any kind of analogy to the ozone issue. We [in the U.S.] actually were the leaders on ozone depletion and on smog, and frankly, we’re doing so badly right now on environmental issues. We’re not going to be the leaders. We’re not going to go into this summit and say anything that will help to create an international agreement.
