Comment Policy

Carl Sagan was known for saying “Extraordinary claims require extraordinary evidence”. If you make an extraordinary claim (such as saying that mainstream science on global warming is wrong) then I will require extraordinary evidence. Failure to provide such evidence is grounds for your comment to be edited or deleted. And if you have some extraordinary evidence, you owe it to all of us to submit it to real scrutiny and publish it in the scientific literature. Fame and fortune await you… if you are correct.

Commenters who are more interested in name calling and yelling, rather than a real discussion, or those who use standard denialism tactics can expect their comments to be deleted.
