Atmospheric Acidity Levels Return to Preindustrial Levels

Repairing the damage humans have done to the environment is a slow process but it can be done!

Thanks to policies put in place by leading economies (the article sites the American Clean Air Act from the 1970s) the acidity levels in the atmosphere has returned to a balanced level. This proves that we can combat climate change using existing political tools – we just need the political will!

“We can see that the acid pollution in the atmosphere from industry has fallen dramatically since manmade acid pollution took off in the 1930s and peaked in the 1960s and 70s. In the 1970s, both Europe and the United States adopted the ‘The clean air act amendments’, which required filters in factories, thus reducing acid emissions and this is what we can now see the results of. The pollution of acid in the atmosphere is now almost down to the level it was before the pollution really took off in the 1930s, explains Helle Astrid Kjær.
