Longer working hours have been linked to higher emissions, yet the climate movement seems reluctant to join the campaign for a four-day week—a potential strategic error given the social, health and climate benefits of working less.

My latest piece for Sower ⬇️ 🧵

Sower · Working less is the most underrated climate solutionFewer work hours can lower emissions. So why isn’t the climate movement fighting for our collective right to relax?

Tracking Global #Forest #Biomass #EU #Space Agency released most detailed #dataset yet on how much #carbon is stored in world’s #forests tracking changes 2007-2022. Built by combining data from multiple Earth-observing #satellites dataset estimates carbon held in woody parts of #trees mainly trunks & branches—across different forest types. While most accurate in areas with up to 400 tonnes of biomass per hectare, it corrects earlier underestimates in high-density forests esa.int/Applications/Observing

www.esa.intESA unveils longest-ever dataset on forest biomassAs the new Biomass satellite settles into life in orbit following its launch on 29 April, ESA has released its most extensive satellite-based maps of above-ground forest carbon to date. Spanning nearly two decades, the dataset offers the clearest global picture yet of how forest carbon stocks have changed over time.Developed through ESA’s Climate Change Initiative, this new long-term record integrates data from multiple satellite missions – and will soon be further enhanced by data from the Biomass mission itself.

Did you know that #coldwater #corals are important components of the marine #carbon cycle? Cool study recently out in @EGU_BioGeo shows how impactful they are as a carbon sink.

bg.copernicus.orgCold-water coral mounds are effective carbon sinks in the western Mediterranean SeaAbstract. Cold-water corals (CWCs) build biogenic structures, known as CWC mounds, that can store large amounts of carbon(ate). However, there is a lack of quantification studies on both recent as well as geological timescales, and knowledge is limited to the accumulation of carbonate (i.e. the inorganic carbon fraction), which ignores the organic carbon fraction. This hinders the calculation of total carbon accumulation rates and a wider understanding of the role CWC mounds play in the carbon cycle. Here, we investigated two cores retrieved from CWC mounds in the Alborán Sea, western Mediterranean Sea, comprising a ∼ 400 kyr record of carbon accumulation. We calculated the accumulation of both inorganic and organic carbon within the CWC mounds. Further, we analysed the same parameters in two cores from the adjacent seafloor (∼ 120 kyr record) to compare the mound records with the surrounding sedimentary deposits. Our results show that the CWC mounds studied accumulate up to 15 g C cm−2 kyr−1, of which 6 %–9 % is derived from the organic carbon fraction. Moreover, during mound formation phases, the mounds store up to 14–19 times more carbon than the adjacent seafloor deposits. We suggest that there is a selective enrichment of organic carbon on the mounds, with about an order of magnitude higher organic carbon accumulation rates than on the adjacent seafloor. Consequently, in phases of mound formation, CWC mounds can be effective local sinks of both inorganic and organic carbon on geological timescales.

Weekend #Plankton #Factoid 🦠🦐
I've always been impressed by this video from New Scientist about #copepods, the planet's most abundant multicellular organism, with interviews from several UK universities, including Exeter and Southampton. Prof Daniel Mayer & others give a lovely explaination on why these #zooplankton, and their poo, are so important to the #ocean ecosystem and #carbon cycling, and why #ClimateChange size shrinkage could have such an impact. #Science 🎥

Historians will look back on this lede from #Carbon County, #Pennsylvania with a disgust we can't even comprehend. tl;dr: Burning used tires and waste #coal to mine #Bitcoin.

Via WBRE/WYOU: "Panther Creek Electric Generating Facility in #Nesquehoning was approved on May 1 to burn tires along with waste coal to create power for its facility. Everything the plant produces goes to crypto mining for Bitcoin."
