Oh they're always on about some bullsh*t that's going to end the world. And people keep believing this type of crap over and over. By the way I forgot all about that acid rain thing, what a nostalgic memory :-)

I remember in the early '90s when they were pushing the idea of the rapture and I asked my dad why people were not freaking out. He was like, they've been saying that for 2000 years.
@CestManan Yeah, we FIXED acid rain in the developed world with environmental regulations. Surely you didn't forget about all those environmental regulations?

The units are megatons per year; the graphs are smoothed.

@ElwoodBlues Acid rain probably never existed to begin with.

They keep inventing these catastrophes and miraculously solving them.
@CestManan You obviously don't live in the northeast where forests were decimated by acid rain. I didn't know acid rain denial was such a big thing!



Environmental regulations reduced SO2 which reduced sulfuric acid in rain. What a difference 30 years made!

Note that rising pH means falling acidity. Every increase of 1 in pH equates to a reduction by a factor of 10 in acid concentration. pH of 7 is neutral.
