Greenland Ice Core Reveals History Of Pollution In The Arctic - But there’s a twist, it was worse 100 years ago
Researcher Joe McConnell said:
Conventional wisdom held that toxic heavy metals were higher in the 1960s and ‘70s, the peak of industrial activity in Europe and North America and certainly before implementation of Clean Air Act controls in the early 1970s.
But it turns out pollution in southern Greenland was higher 100 years ago when North American and European economies ran on coal, before the advent of cleaner, more efficient coal burning technologies and the switch to oil and gas-based economies.
