We had many of those old ACs to know they were shit. Modern ones are great compared to them.
I don’t get it :(
The picture is used as a classical example of survivor bias. When air planes came back after combat, they checked where all the bullet holes were. That’s what the graph shows. The naive conclusion is that the areas that have the most bullet holes should be reinforced with armour. The correct conclusion is that the areas that don’t have bullet holes are the critical zones that need to be reinforced, no planes return after getting a bullet there, which explained why there is no data showing the bullet holes in those locations.
Survivor bias.
I suppose what’s being implied, is that the only old ass air conditions that you see nowadays, are above average and that’s why they’ve survived.
CFC’s are great at coolimg things as long as you do not care about having an ozone layer.
I thought that was over
The ozone hole is mostly repaired, because we stopped using CFC’s.
I think it’s more accurate to say the problem is mostly solved and its on track to being repaired rather than mostly repaired.
Antarctic ozone hole:
2000: 28.3 million sq km (largest recorded).
2020: 24 million sq km.
2024: 20 million sq km (approx 3x size of usa).Global ozone levels will return to 1980 levels around 2040.
Arctic ozone will recover by 2045 (currently around 1 million sq km).
Antarctic ozone hole will fully recover by 2066.Yup much like with acid rain Reagan and George HW Bush stepped up environmental regulations to confront the problem.
As most of the problem was due to America’s use of CFC’s it was their issue to solve.
