A few items of interest this week.
1. A new study by Spielhagen and co-authors in Science reconstructs temperatures of North Atlantic source waters to the Arctic for the past two millennia, adding another very long-handled Hockey Stick to the ever-growing league.
2. From last week, an article in Science Express by Buntgen et al reconstructing European summer temperature for the past 2500 years, finding that recent warming is unprecedented over that time frame, and providing some historical insights into the societal challenges posed by climate instability (listen here for an interview with mike about the study on NPR’s All Things Considered).
3. The team of ice core researchers at WAIS Divide reaches its goal of 3300 meters of ice. [WAIS Divide, central West Antarctica, is a site of significant warming in Antarctica, over at least the last 50 years, a result recently confirmed by the study of O’Donnell et al. (2010); Stay tuned for more on the that soon].
Other Miscellaneous Items:
1. More in Nature on data sharing.
2. A great primer in Physics Today on planetary energy balance from our very own Ray Pierrehumbert (link to pdf available here).
3. Now shipping are David and Ray’s The Warming Papers and Ray’s Principles of Planetary Climate.
