- Was there a Medieval Warm Period?: "The Medieval Warm Period spanned 950 to 1250 AD and corresponded with warmer temperatures in certain regions. During this time, ice-free seas allowed the Vikings to colonize Greenland. North America experienced prolonged droughts. So just how hot was the Medieval Warm Period? Was it warmer than now? A new paper Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly (Mann et al 2009) (see here for press release) addresses this question, focusing on regional temperature change during the Medieval Warm Period and Little Ice Age."
- Climate Feedback: Interview with NRCC: James Hansen: "In an exclusive interview published today on Nature Reports Climate Change, climate scientist James Hansen talks about his forthcoming book, Storms of My Grandchildren. Arguably the world’s most famous climate scientist, and Director of NASA’s Goddard Institute of Space Studies in New York, Hansen’s conviction that a climate catastrophe is looming has led him, in recent years, to increasingly take on the role of advocate, sending numerous pleading letters to world leaders and CEOs, and attending well-publicized protests against coal plants.[...]"
