Hundreds of millions of years ago, in the middle of what would eventually become Canada’s Yukon Territory, an ocean swirled with armored trilobites, clam-like brachiopods and soft, squishy creatures akin to slugs and squid. A trove of fossils and rock layers formed on that ancient ocean floor have now been unearthed by an international team of scientists along the banks of the Peel River a few hundred miles south of the Arctic’s Beaufort Sea. The discovery reveals oxygen changes at the seafloor across nearly 120 million years of the early Paleozoic era, a time that fostered the most rapid development and diversification of complex, multi-cellular life in Earth’s history. “It’s unheard of to have that much of Earth’s history in one place,” said Stanford University geological scientist Erik Sperling, lead author of a July 7 study detailing the team’s findings in Science Advances. Most rock formations from the Paleozoic Era have been broken up by tectonic forces or eroded over time. “There’s nowhere else in the world that I know of where you can study that long a record of Earth history, where there’s basically no change in things like water depth or basin type.” - Geology Page
Midwest power plants face shutdown after EPA proposes denying requests to keep using unlined coal ash ponds
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
Coal Powered the Industrial Revolution. It Left Behind an ‘Absolutely Massive’ Environmental Catastrophe
I started a CGCC Facebook page in May of '20 to share geo-environmental news but had accuracy concerns with FB. GeoNews is a response and partial solution, sharing a few items from reliable sources each week.
