A growing body of evidence suggests that a massive change is underway in the sensitive circulation system of the Atlantic Ocean, a group of scientists said Thursday. The Atlantic meridional overturning circulation (AMOC), a system of currents that includes the Florida Current and the Gulf Stream, is now “in its weakest state in over a millennium,” these experts say. This has implications for everything from the climate of Europe to the rates of sea-level rise along the U.S. East Coast. Although evidence of the system’s weakening has been published before, the new research cites 11 sources of “proxy” evidence of the circulation’s strength, including clues hidden in seafloor mud as well as patterns of ocean temperatures. The enormous flow has been directly measured only since 2004, too short a period to definitively establish a trend, which makes these indirect measures critical for understanding its behavior. - Washington Post
Royal Dutch Shell, one of the multinationals that defined the oil industry, is slowly turning away from the fossil fuel that made its fortune over the decades but also worsened a global climate crisis. The company said Thursday that its production of oil peaked before the coronavirus pandemic and will fall steadily as it attempts an ambitious pivot toward less polluting forms of energy. It's a milestone for the company and reflects the urgency facing governments and companies to reduce climate-warming emissions. Shell unveiled new plans for reaching its goal of being carbon neutral by 2050 that include a 1% to 2% drop annually in oil output. It will eliminate seven of its 13 refineries and aims to cut production of gasoline and diesel fuel by 55% over the next decade. The plan is part of a wider push, particularly among European oil companies, to overhaul their operations to reduce carbon emissions blamed for global warming while still making money. BP said last year that it wants to eliminate or offset all carbon emissions from its operations and the oil and gas it sells to customers by 2050. - ABC News
I started a CGCC Facebook page in May of '20 to share geo-environmental news but had concerns about FB's issues with accuracy. This page, GeoNews, is a response and partial solution, sharing a few items from reliable sources each week.
