Suppose, back in the 1600s, someone had penetrated into the bastion of orthodoxy that was the church, and accepted (in the name of the Pope) that the solar system was heliocentric, would it have not been a wonderful thing?
One such incident occured today in washington DC, when a very agreeable yes-man posed as a member of America's chamber of commerce, an organization whose anachronistic denial of climate change makes them appear like the modern day flat earth society.
For a few moments, some of the people in DC believed that the powerful chamber of commerce stopped living in denial and had come to accept climate change as a reality. These were just a few minutes. The chamber members finally woke up, but it was fun while it lasted..
