How times change

A reader sent this scan to me. Incidentally this was published just two years before the National Academy of Sciences first talked about global warming. Doesn’t mean it isn’t happening, just that predicting something as complex as climate is very very difficult.

UPDATE: Have had pointed out this is near identical to this 2007 climate change cover. This may be a photoshop. However Time in 1974 did run a story called “Another Ice Age?”. So someone has altered a modern cover to fit the old story.

I did check it out on Snopes, which is what I do with a lot of material sent to me by e-mail, but Snopes did not have an article on the cover and it was well known Time did run such an article, so I had no reason to doubt it was an actual cover.

This one is genuine!
