I don't write quickly, and I don't want to.

I'm not against entertainment: if someone wants to read nonsense-mongers, let them, but I resent the appearance of parity between two articles on an issue as serious as climate change when one article is actually gibberish masked in pseudoscience and the other is well informed and accurate.

Cultures have long heard wisdom in non-human voices: Apollo, god of music, medicine and knowledge, came to Delphi in the form of a dolphin.
