If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so. – James Lovelock
What I like about sceptics is that in good science you need critics that make you think: Crumbs, have I made a mistake here? If you dont have that continuously, you really are up the creek. The good sceptics have done a good service, but some of the mad ones I think have not done anyone any favours. – James Lovelock
