In reply to Big Ger:
Have you ever been climbing in the Elbe sandstone? If you have the opportunity, take a little detour to the Erzgebirge (or any of the other border ranges further east, e.g. the Estergebirge, Sudetes, etc.). You will find areas dozens in km of length, and extending several km dowm from the ridge line where ALL trees have died due to acid rain during the 1980s.
Similar damage, just less severe, could at the time be observed in about 70% of all forests in Germany, with hardly any individual trees not affected.
Tree health has since recovered, and even the areas in the Erzgebirge are slowly recovering (square km areas covered with 20 YO trees really look weird!), due to sulfur extraction from the coal fired power plant exhausts (and, to a lesser extent, sulfur removal from car fuel).
Acid rain was no joke or myth, and the worst consequences were avoided in the West just in time, but somewhat too late in East Germany and the Czech Republic (who upgraded their power plants after Germany paid for the extraction systems).
This action was the first, great success of the Green movement in Germany. Sulfur removal was ridiculed and declared unnecessary and technically impossible at the time, but is now mainstream politics and technical state of the art. For some reason, though, the foresight and tenacity of the early environmentalists is still ridiculed.
I hope that we will in a few decades be able to look back on climate change and conclude that we just got away with a black eye. I am not too optimistic, though, the problem is much bigger. CO2 is less easily removed than SO2/3, any remedial action will thus be costly and involve changes in lifestyle, and the consequences of failure are much worse and potentially more permanent and irreversible.
