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.

- styfle 3y agoThe 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”
