By 2100, we could be heading towards a loss of life in our oceans that rivals some of the largest extinction events in Earth's history if we don't continue to tackle the climate catastrophe, new modeling warns. But "it is not too late to enact the reductions in greenhouse gas emissions needed to avoid a major extinction event," Princeton geoscientists Justin Penn and Curtis Deutsch explain in their paper. Using modeling calibrated against ancient fossil records, they predict the consequences of runaway climate change on marine animals and provide a plausible explanation for an enduring ocean mystery in the process. - Science Alert
As Lake Powell Hits Landmark Low, AZ Looks to a $1 Billion Investment and Mexican Seawater to Slake its Thirst
The Arizona Corporation Commission rejected the adoption of a set of clean energy rules on Wednesday in a 3-2 vote. The rules package included a timeline for 100% carbon-free electricity, new demand-side resources standards and integrated resource planning reforms. The package would have expanded energy efficiency programs for Arizona Public Service (APS) and Tucson Electric Power (TEP), offering rebates to customers for replacing inefficient appliances and upgrading lighting. Commissioner Jim O'Connor, R, voted against the rules package despite his work last May with Commissioner Anna Tovar, D, to revive the package through a separate rulemaking. Advanced Energy Economy (AEE) called O'Connor's vote "surprising." - Utility Dive
Carbon dioxide can be harvested from smokestacks and used to create commercially valuable chemicals thanks to a novel compound developed by a scientific collaboration led by an Oregon State University researcher. Published in the Journal of Materials Chemistry A, the study shows that the new metal organic framework, loaded with a common industrial chemical, propylene oxide, can catalyze the production of cyclic carbonates while scrubbing CO2 from factory flue gases. - Phys.org
Berkeley, California-based carbon transformation company Twelve and Tulsa-based Emerging Fuels Technology (EFT) today announced that they have produced the first fossil-free jet fuel from carbon dioxide using an electrochemical process. The project received funding from the US Air Force. The new biofuel, which is called E-Jet, can be used by both commercial and military aviation. Biofuels are notoriously expensive. But where many processes have proven the ability to yield 65% of jet fuel from initial feedstock, EFT says its process yields more than 80%. EFT has also signed a licensing agreement with Norwegian company Nordic Electrofuel, which also makes fossil-replacement fuels. Twelve and EFT state that fossil-free jet fuel E-Jet is a drop-in replacement for petrochemical-based alternatives, and no changes are required to existing plane design or commercial regulations. - Electrek
