"People often ask if I believe in global warming. I now just reply with the question: 'Do you believe in gravity.'" — Neil deGrasse Tyson, American astrophysicist and science communicator.

Notes: I blogged about this question: 'Do you believe in evolution or climate change?'in a post on June 5, 2012, Part II: Understanding Climate Change Starts with Understanding 'What is Science? This is what I wrote:
"Amazingly, science is not based on belief. It is based on evidence. According to the National Academy of Sciences, the definition of science is "The use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process."
To say I believe in evolution or climate change would be silly. It would be as bizarre as saying, "I believe in gravity." Based on overwhelming evidence, I accept gravity. The same is true for evolution and climate change. I do not believe in evolution or climate change. However, based upon multiple lines of evidence from numerous sources of inquiry, I strongly accept theory of climate and evolution."
