More evidence today that climate change could be the result of variation in solar luminosity, courtesy of the National Post (via Marc Morano at EPW):
Mars's ice caps are melting, and Jupiter is developing a second giant red spot, an enormous hurricane-like storm. The existing Great Red Spot is 300 years old and twice the size of Earth. The new storm -- Red Spot Jr. -- is thought to be the result of a sudden warming on our solar system's largest planet. Dr. Imke de Pater of Berkeley University says some parts of Jupiter are now as much as six degrees Celsius warmer than just a few years ago. Neptune's moon, Triton, studied in 1989 after the unmanned Voyageur probe flew past, seems to have heated up significantly since then. Parts of its frozen nitrogen surface have begun melting and turning to gas, making Triton's atmosphere denser. Even Pluto has warmed slightly in recent years, if you can call -230C instead of -233C "warmer." And I swear, I haven't left my SUV idling on any of those planets or moons. Honest, I haven't.And speaking of extraterrestrial explanations for global climate change, don't forget to set aside some time to watch Martin Durkin's new documentary "The Great Global Warming Swindle."
