The Futile Quest for Climate Control

If you find yourself with nothing to do of an evening, read The Futile Quest for Climate Control, a very long and interesting article.

Don't have the time?  Here's a quick bit:

In 1990 the IPCC's first Assessment Report concluded that no human influence on climate was discernible. Despite the huge expenditure of research effort and money since that time, the boundary arguments to the debate have scarcely moved. We now have copiously more data and more powerful computers, have spent upwards of $50 billion on climate research, and are the beneficiaries of twenty years of hard thinking by some of the world's most accomplished scientists. Yet the protagonists in the debate remain in the same bunkers they occupied in the early 1990s, and a clear human-caused climate signal continues to elude us.
