I like Rober J. Samuelson, because he tries to get to the heart of the matter and face facts. He acknowledges the complex issues our society faces, and keeps letting his readers know that we’re not facing them realistically, because in some cases we want benefits, but at a discount. Or, we want things that are not practical either technologically, or economically. Maybe he’s quixotic. It seems he never underestimates the public’s ignorance, or apathy towards these issues.
A recent article he wrote summarizes his point of view well, called “What if We’re to Blame?”
Another I’d recommend is “Greenhouse Guessing”.
