Last I heard those emissions had starting going back down. Was there anything new on that front since then?
Probably one of those times I need to lament the current state of journalism that that was included. I’d argue the ozone layer is one where there is global political momentum with an example of some recent mystery emissions such as this article. That said this article we were already discussing seems to bring up some other mechanisms for the hole enlarging beyond the usual ozone depleting substances.
Well that’s a throwback. Not sure I care for this particular reboot of my childhood media.
Ground level ozone and the ozone hole are two different issues. The delayed EPA regulations would be limiting ozone produced. At ground level, ozone has various health hazards. The ozone hole is from ozone depleting substances reaching high altitude in the environment and destroying naturally occurring ozone. That high elevation ozone blocks UV light from the sun, and is protective for those of us who dislike skin cancer it what not.
I generally settled on Fusion360, but Alibre Atom was promising aside from some system stability issues on my desktop. I really wanted to like freeCAD, but I just didn’t have the time to invest in learning its quirks.
