The idea that Global Warming may not be human caused is a radical idea these days, completely non politically correct and disruptive - hence a good candidate for YC news. I don't know anything about the source of this release, but I have read now at least 10+ scientific articles with evidence on the likeliest cause of warming being the Sun, especially given the fact that all the planets in the Solar system are also warming up at the same time (as reported by NASA), and the fact that this pattern has occurred in the past countless times.
He's right, NASA has seen the same amount of warming on Mars over the last 50 years as we have experienced here. It doesn't mean that Global Warming isn't really a problem but there might not be anything we can do about it except plan for life afterward. Even if it is man made do you really think a few light bulbs and hybrids are going to make any difference? You can't stop Global Warming at this point, no matter what the cause is.
From the Nature piece: "Solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades."
About Scarletta and West: "However, they emphasized that their findings do not argue against the basic theory that significant global warming is occurring because of carbon dioxide and other "greenhouse" gases." http://www.dukenews.duke.edu/2005/09/sunwarm.html
The Telegraph article is vague. That's an example of why rms asked for journals.
