I no longer worry. I'm extremely pessimistic about the impending climate change. I believe Sabine isn't pessimistic enough about what to anticipate. Consider the tundra methane emissions and the explosive release of methane-hydrates from the oceans, along with water vapor, a potent greenhouse gas. The disaster looming over all ecosystems (a mass extinction event) that will happen in decades and the doom-phase could last for 200,000 years. The chances of humanity surviving are incredibly slim, IMO. We can't colonize Greenland or Antarctica due to the lack of fertile soil, and it would take thousands of years to develop it. Without saying so, we don't have this amount of time.

I am glad that I survived oil outage, sour rain, the Ozone hole, mass famine because of overpopulation. All in a lifetime. I must have had sheer luck.

There was massive concerted effort to stop acid rain and ozone depletion. Maybe we should try that for the climate crisis if we want similar success at preventing catastrophe.

Amazing how the ozone hole repaired itself despite China releasing thousands of tons of CFCs.

The article doesn’t seem to support your claim.

“After the ban came into force, global concentrations of CFC-11 declined steadily until about 2012. However, last year scientists discovered the pace of that slowdown slowed by half between 2013 and 2017. Because the chemical is not naturally occurring, the change could only have been produced by new emissions.”

“If emissions do not decline, it will delay the recovery of the Antarctic ozone hole, possibly for decades”

CFC-11 is one specific CFC, you need to look at all of them. Overall they’re increasing, yet the ozone layer has continue to “heal”.
