Another climate book: The Ice Chronicles: The Quest to Understand Global Climate Change by Paul Mayewski and Frank White focuses on the data from Greenland ice cores: how it was obtained and what it tells us. This book is from 2002.

A report from 2010 by William Freudenberg to AAAS suggests that climate consensus statements are likely to understate the significance of the problems that need to be faced. New scientific findings are found to be more than twenty times as likely to indicate that global climate disruption is “worse than previously expected,” rather than “not as bad as previously expected,” contrary to the usual framing of the issue in the U.S. mass media.

In the same session, Max Boykoff asserts that “Outlier voices have gained more prominence and traction in mass media over time through a mix of political economic, cultural, and social factors. Moreover, institutional workings of mass media – such as journalistic norms, values and practices – can contribute to such patterns. Through these processes, all too often many media reports – from daily print media to radio, television and internet stories – conflate the vast and varied terrain of climate science and policy as a unified issue. To the extent that mass media – and claims-makers (focusing on ‘climate denialists’) who find discursive traction here – fuse these issues into gestalt as ‘the climate change debate’, they contribute to ongoing illusory, misleading and counterproductive debates within the public and policy communities, and the collective publics are poorly served.”

William Murray with Margaret Leinen and Christopher Knowlton have a recent Nature paper investigation the natural role of wind-driven transport of iron, in many ocean regions the limiting nutrient, in CO2 draw-down in the glacial cycle, with obvious implications for geoengineering.

The Register. a British tech paper with a high snark index that often comes down as climate-denialist favorably reviews a middle-of-the-road projection for Australia, which has a broad uncertainty range and a very fat and scary tail.

A large modeling study claims to nail the Little Ice Age.

And there’s compelling evidence published in Nature linking ambient CO2 directly to obesity in humans and animals. Hmph. Knew it wasn’t my fault.
