OK, at this stage of the game, denying the reality of climate change, a.k.a. global warming, is exactly like a guy who smokes four packs of Marlboros a day but โdeniesโ the threat of lung cancer. He can say he doesnโt โbelieveโ in lung cancer all he wants. He can say he doesnโt believe that smoking 80 cigarettes a day poses a threat to his longevity. Fine. But when that big black blob shows up on the chest X-rayโwell โฆ
Itโs become slightly fashionable to opine that itโs already too late. That the massive machinery of human-fueled climate mischief is now in place and, since weโre reluctant to do a damn thing about it, we are, ultimately, doomed to feel Gaiaโs weather-rockinโ wrath more and more as the 21st century marches on. I confess to having a soft spot for these types of apocalyptic conversationsโoh, you betcha. But maybe itโs time to pump the brakes just a tad on OID (our inevitable doom) by recalling acid rain and the ozone layer. Remember those?
Acid rain was detected in the lakes of the industrial northeast in the late โ70s, and the causes were quickly discovered. Yes, geologic activity was a trouble-maker, but humanity was as well, especially since we were belching a lot of sulfur dioxide into the atmosphere. Many lakes and streams were found to have harmful acidic pH levels, and the effects on overall ecology were negative. So you know what happened? We actually did something about it! You know, like, in a scientific, bipartisan way? I know, weird, right?
We studied the situation through the โ80s, and by 1990, Congress was ready to do something. No, really! It passed amendments to the Clean Air Act that reduced emissions of sulfur dioxide, and, as a result of us acting with actual intelligence, levels of acid rain have since dropped 40-60 percent. Gee, waddyaknow. We really โฆ did something.
Also in the โ70s, scientists discovered that our use of CFCs (choloroflurocarbons) in aerosol sprays was mangling Earthโs ozone layer, which has the very important job of protecting us from the sunโs vicious UV radiation. So again, the governments of industrial nations actually took action (no shit!) and capped the use of CFCs, and by 2003, well, waddyaknow again. Measurements confirmed that ozone depletion was being reduced.
No, man-caused problems with the ozone and acid rain werenโt eliminated, but they were mitigated and controlled. See, back then, we didnโt suspect science, we respected it. And then used it. What a concept. So maybe, just maybeโitโs not too late with climate change?
