A new study considers the domino effect on certain species caused by the extinctions of other species, those that are primarily the result of climate change (Futurity). The authors made observations showing that “Some species with a very low likelihood of climate-related extinction according to the traditional model are at high risk of extinction due to their dependencies.” This is especially true in the Mediterranean region—“With such a high fraction of species and their interactions being driven extinct, the remaining network is more fragile and therefore prone to co-extinction cascades.”

Current flooding of the Mississippi River is compared with the ‘Great Flood’ of 1927 (USA Today). The earlier event set many amazing standards that look unbreakable but the current version is even worse in some locations.

A set of reasons for why we have just one year to start taking serious action on climate change (CNN). The author, a vice president of World Resources Institute, explains why the slogan, ’12 years to save the Earth,’ can only make sense if a massive undertaking begins no later than next year. The Paris Agreement of 2015 is set for a major update when national leaders reassemble in New York next year to state the full commitments they are ready to proceed with.

New research has an improved understanding of jet stream configuration (Phys.org). Some of the findings of a new model are rather obscure and difficult to communicate, but there is one exception: “In addition, with the new model the researchers can also more closely analyze the causes of the meandering jet stream. Our study shows that the changes in the jet stream are at least partly due to the loss of Arctic sea ice. If the ice cover continues to dwindle, we believe that both the frequency and intensity of the extreme weather events previously observed in the middle latitudes will increase…..our findings confirm that the more frequently occurring cold phases in winter in the U.S., Europe and Asia are by no means a contradiction to global warming.”

A major step forward for flow battery technology (ScienceDaily). Harvard University researchers have solved the one problem that held back commercial development of this low-cost form of stationary energy storage. “Such devices are needed to allow the electric grid to absorb increasing amounts of green but variable renewable generation.” Wind and solar facilities should soon become yet more competitive as a result.
