I think it is important to acknowledge that there is a continually rolling narrative about an impending catastrophe in 15 years from now.

In 1988, New York was going to be underwater by 2000. Etc. It is crazy to look back at the endless series of predictions - all of them very alarming and all of them, it turns out, completely wrong.

It is also worth remembering that in the 1970s the huge, science-based headline was that we were sliding into an ice age. The 1930s and 1940s had been particularly hot, and by the 1970s the decline in average temps had everyone worried. Newspapers ate it up. Like they are now. The predictions were alarming.
