Norwegian newspaper clipping from 1966 mentioning "the greenhouse effect" and "defrosting of the Arctic" and how we may already be causing such an effect through "negligence" (the topic of the article is apprently how one might go about defrosting the Arctic on purpose).
We've known about global warming for ages. The problem is that public opinion isn't coherent enough to force political action. We are blind fools fighting over the deck chairs on the Titanic.
