JOHN TIERNEY: Hacking The Climate Debate: “I’ve long thought that the biggest danger in climate research is the temptation for scientists to lose their skepticism and go along with the ‘consensus’ about global warming. That’s partly because it’s easy for everyone to get caught up in ‘informational cascades’, and partly because there are so many psychic and financial rewards rewards for working on a problem that seems to be a crisis. We all like to think that our work is vitally useful in solving a major social problem — and the more major the problem seems, the more money society is liable to spend on it.”
