During the first century an astronomer, Ptolemy, offered the theory that earth was at the center of the solar system, and the sun and planets revolved around it. This theory was accepted until Galileo came along several centuries later and averred the sun was actually the center of our solar system, and the earth and planets revolved around it.
This created a controversy that upset every body. The Catholic Church even sentenced Galileo to death if he persisted in publishing such heresy.
Now we have the controversy whether people are to be blamed for climate change. Scientists are split.
Why don’t we hold an election among scientists to settle the matter, and stop all this fuss? Whichever side wins, wins and that’s that.
