Raymond, That's the way science is. Scientists who measure the temperature on Pluto, Triton, or Mars, are going to report those findings. They are not going to wait the years that it might take to determine if the output of the Sun has changed. That is for another paper, and another grant (or possibly another investigator). Speaking of other investigators, when you wrote to John (http://www.siliconinvestor.com/readmsg.aspx?msgid=19262074) that his "position as a skeptic on global warming just got dealt another blow", you provided a link to an article in the guardian: guardian.co.uk In that article, was this: "Dr Sallie Baliunas at the Harvard College Observatory in Massachusetts, for example, maintains that the recent warming could all be down to changes in the strength of sunlight falling on the planet. She concluded that during the 20th century, earth went through a cycle of natural climatic change. According to her data, from 1900 to 1940 the planet warmed slightly, then cooled from 1940 until 1970, then warmed up again from 1970 onwards. Given that 80% of the world's carbon dioxide emissions have been pro duced since 1940, the expected effect, if carbon dioxide was causing global warming, would be higher temperatures not lower, she said. Dr Baliunas's data also concluded that the period of warming between 1900 and 1940 must have been due to natural causes, most likely increased sunlight hitting the earth's surface, since carbon dioxide emissions were negligible at the time. The evidence, she said, pointed to variations in the sun's brightness being the cause of the planet's warming up, not carbon dioxide." re:"You are quite talented at spreading red herrings, apparently. The commonality to all the articles you provided seems to be that none of the scientists are measuring increasing solar energy in our solar system.... While you provide some esoteric data points, I cannot see how a volcano on Triton or the elliptical orbit of Pluto have anything whatsoever to do with the measured changes in temperature here on earth"
