It's healthy to be a sceptic but sometimes one wonders what it takes to change an opinion?

Sceptic 1 admitted today that he was wrong about global warming: Sceptic admits global warming is real

Sceptic 2 has gone on record to say that he and the producer of his webcast believe that the concept of global warming is being pushed by governments in order to promote higher taxation and greater governmental controls of our lives.

Hmmmm...Sceptic 2 also sold some Tyhee.

I wonder if two wrongs could make a right?
