    New paper. I wish this wasn't the case, but most progress on reducing US greenhouse gas emissions is likely spurious. Why? EPA underestimates methane emissions from oil and gas. Relevant today as Repubs vote to gut IRA's methane monitoring/mitigation program. 🧵

    Two graphs from the paper. The left graph shows US net greenhouse gas emissions from 1990 to 2022. The official EPA estimates decline fairly steadily from 6.6 gigatonnes per year in 2005 to 5.5 in 2022 (17% below 2005 levels), largely reflecting natural gas displacing coal for electricity generation. The adjusted estimates, which reflect independent measurements of methane emissions from oil and gas infrastructure, end at 6.3 gigatonnes per year in 2022 (only 5% below 2005 levels). The right graph shows 2022 emissions increasing linearly with the assumed global warming potential of methane. Climate scientists are divided on whether to use the 100-year GWP, 20-year GWP, or something in between. With methane warming impacts assessed via the 20-year GWP, the central 2022 emissions estimate is 7.9 gigatonnes per year - 20% *above* the EPA's official 2005 estimate. Caption: Figure 1: Left: United States net greenhouse gas emissions over time. Right: Scaling of 2022 net emissions with methane’s GWP. After adjustment to reflect recent measurements of methane emissions from natural gas infrastructure, United States net emissions remain nearly as high as their 2005 level.

    We had a huge haboob come in yesterday. This is the THIRD one this year. Long time locals are saying it's the biggest/worst they'd ever seen hit here. #NewMexicoTrue #ClimateChange #DesertLife
