The late 2013 to 2014 Intergovernmental Panel Climate Change Report will reportedly not incorporate melting permafrost’s probably gigantic carbon releases — an omission that promises to make it as subject to controversy as its predecessors 0

Citation Kevin Schaefer, Hugues Lantuit, Vladimir E. Romanovsky, Edward A. G. Schuur, and Isabelle Gärtner-Roer, Policy Implications of Warming Permafrost, United Nations Environment Programme [ISBN: 978-92-807-3308-2] (November 2012) Note This document is not dated. That is why I included the ISBN. The November 2012 date that I have attributed to the report comes from the [...]

Increasing atmospheric carbon dioxide appears to directly weaken glacial ice bonds — by competing with water molecules for hydrogen bonds 0

Citation Zhao Qin and Markus J Buehler, Carbon dioxide enhances fragility of ice crystals, Journal of Physics D: Applied Physics 45(44): 445302, doi:10.1088/0022-3727/45/44/445302 (early online publication, 10 October 2012) A surprisingly subtle corollary to greenhouse gassing — the presence of CO2 in ice reduces fracture strength by 38 percent From the paper’s conclusion: We find [...]

A tidbit about ocean acidification that recalls chemistry and biology classes — with concerning effect 0

Citation Robert F. Service, Rising Acidity Brings an Ocean of Trouble, Science 337(6091): 146-148 (13 July 2012) In oceans — a pH drop from 8.2 to 8.1 appears to be a very big deal for some important critters That’s a 30 percent increase in oceanic acidity from before the Industrial Revolution to the present. Even [...]

Chrysanthemums adapt to irregular lighting patterns that disrupt their normal circadian rhythm — and, if cumulative light duration is short, they grow faster to compensate 0

Interesting, for those of us who wondered how erratic interior lighting affects plants Katrine Heinsvig Kjaer and Carl-Otto Ottosen were curious about plant growth under greenhouse conditions in which northern hemisphere growers turned grow lights on during off-peak electricity times and off during more costly peak periods: Leaf expansion and stem elongation occurred at a [...]
