Nigel Leck got tired of arguing with people who were skeptical about global warming science. Noticing that most of them used the same debunked arguments over and over again, he decided to make a Twitter chatbot to answer them automatically. The bot is named @AI_AGW (the photo is of HAL 9000 from 2001: A Space Odyssey‘s camera-eye), and every 5 minutes it searches the twitterverse for debunked arguments. When it finds one, it sends a reply with a link to a source that explains the counter-argument.
So far the bot has made almost 40,000 tweets, though not all of them to climate skeptics. Now that the bot is better known, lots of people are testing it just for fun.
