Climate change, before that it was called Global warming.
No, it was never called global warming. They are two separate but related issues. Global warming
causes climate change. Global cooling would also cause climate change. Massive deforestation would cause climate change, as would reforestation. In fact that has already been documented. When Europeans brought diseases to North America in the 15th and 16th centuries, there was a lot of land cleared for farming by natives. After disease killed over 90% of the native population, reforestation occured, and there were observable climatic shifts. Plate tectonics, either short-term like earthquakes, or long-term like continental drift, change ocean currents and that also causes climate change.
Are any of you old enough to remember the "acid Rain" scare of the 1970's and 80's////basically it was saying ontario forests and many lakes in muskoka are dead lakes because of this........then we didnt hear anything...
We don't hear much about it anymore because we fucking did something about it. Kind of like how we don't hear much about polio or smallpox now.
Oh, this should be fun.
Remember the big “acid rain” scare during the 1970s and 1980s attributing damage to lakes and forests to emissions from Midwestern utilities? If so, did you ever hear the results of a more than half-billion-dollar, 10-year-long national Acid Precipitation Assessment Program study that was initiated in 1980 to research the matter?
Probably not.
As it turned out, those widespread fears proved to be largely unfounded, since only one species of tree at a high elevation suffered any notable effect, and acidity in lakes was traced to natural causes. The investigating scientists reported that they had “turned up no smoking gun; that the problem is far more complicated than it been thought; that other factors combine to harm trees; and that sorting out the cause-and-effect was difficult and in some cases impossible.”
And you provide no source for any of that bullshit? I've been canoeing and camping in the north most of my life, and with the military, and saw the changes when measures were taken to reduce acid rain. Lakes near Sudbury were almost dead, with little but blue-green algae living in them. Now they are returning to health, with biodiversity increasing.
I can also use the Google. Makes me wonder how all these large institutions take it so seriously if it's wrong. I guess Greenpeace and the Sierra Club must have enough money to bribe them. Start with these.
