It can be hard to find good news about the future so here is a win for the environment. I remember when holes in the Ozone Layer were some of the biggest climate emergencies we were facing. Lets hope we do the same with carbon emmisions!

The Montreal Protocol, an international treaty to protect our ozone signed in 1987, has been a success, declared the U.N.-backed scientific panel in a report first released in October 2022 and formally presented on Monday at the American Meteorological Society meeting.
Despite a major setback in the 2010’s, the amount of ozone-depleting chemicals emitted worldwide has decreased since 2018. In sum, nearly 99% of those harmful compounds have been phased out since the 1980’s, according to a Monday press release. If all continues according to plan, the ozone layer is expected to recover to pre-1980 levels worldwide, including over the Antarctic, by 2066, the assessment says.
