Fallen Angels by Niven Pournelle & Flynn

Can I recommend a book by Larry Niven, Jerry Pournelle & Michael Flynn? It's called "Fallen Angels" and was published by Pan in 1991. I got my copy via Ebay. Here's the blurb from the back cover-

"2073... and Earth falls victim to the advance of a new Ice Age. As the ruling Green Party outlaw the technology that can save the planet, a spaceship crashes in the frozen wastes of the American mid west."

The authors wrote the book just as the global warming conspiracy was getting under way. They saw it for what it is, bad science used to advance a political agenda.
Almost twenty years on, and what they wrote about, and warned us about via a drugstore paperback novel is coming true. It's good story, but you have to be a Science Fiction buff to get all the sub plots.

George Orwell wrote "Animal Farm" and "1984" as a warning to us about the dangers of socialism. He could have stood on a soapbox and preached to us but I doubt if many would have listened. However, like Robert Heinlein, Ayn Rand, Aldous Huxley and others, he understood that he could get his ideas over if they were presented as a work of fiction.

My main concern about Orwell's work is this- far from being a warning to us, his words have been adopted by the left as a training manual.
