- roflmaostc 1y agoactually the reflectance of UV is usually much lower than visible light. https://www.nature.com/articles/s41598-021-01315-1/figures/2 https://www.nature.com/articles/s41598-021-01315-1/figures/2
- ricw 1y agoIt’s actually much more that the ozone layer, which filters uv, is much thinner than it was even 60-70 years ago. The ozone layer might be growing again, but at a very slow pace. Simple fact is, we’re much more exposed to uv than prior generations.
- dgacmu 1y ago"much" more might be overstating it? We get about 6% more UV: https://www.sciencedaily.com/releases/2010/03/100316142529.htm https://www.sciencedaily.com/releases/2010/03/100316142529.h... Which corresponds with the ozone layer being about 5% thinner: https://www.clo.nl/en/indicators/en021819-ozone-layer-1980-2022 https://www.clo.nl/en/indicators/en021819-ozone-layer-1980-2... Not good (or good for us) but also not a huge huge change, since we stopped the thinning of the ozone layer mostly in time.
