According to this streaming video, global warming is apparently not a new phenomenon: It was predicted in the early 1950s [1:18].

I would almost count it unethical that the New Scientist has a thing that looks like a blog post (an article you can comment on) that has some science in it, but that you have to be a paid subscriber to comment on. WTF New Scientist? What are you trying to pull?
But that's OK, I've got a blog and…

Very interesting....very interesting...--as that little German soldier used to say on laugh-in. But that was before you were born.
Whilst accurate, maybe a poor choice of wording? I understand the signal has been detectable for many decades, and the CO2 physics are well-known (for quite a long time, over one hundred years), but no-one really put the pieces together until relatively recently. So whilst the phenomenon isn't new, the realisation that it's happening on Earth and is driven by people is new. Having said that, I recall reading recently someone speculated around-ish 1900 that people might be driving such a phenomenon--but now I can't find the reference! ;-(
I read one of the early papers on the Mona Loa sequence, which discussed this. It's been clear for quite some time that the initial effect of increased CO2 was increased retention of solar heat. The big question was what would other stuff (water vapor, clouds, ocean/air currents, plants) do?
I definitely remember reading (as a child) about "the greenhouse effect" back in the early 1970s, probably in National Geographic. Global Warming was also a major part of the setting for 70s scifi flicks like "Soylent Green" (1973).
Global Warming was all over the popular consciousness in the early 70s. It wasn't until the 80s when the Cold War heated up and Sagan started warning about nuclear winter that people seemed to forget. People have such short memories.
I have added a link to this to my post from last night, in which I mentioned precisely this: that we knew about this back in the 1950s. We, as in our society; I, personally, didn't hear about it until the 1960s.
But that's going on 50 years ago.
But we relegated it to scifi, and went about our merry ways. Shame on us!
