and coal) represent a substantial contribution to greenhouse gas emissions with substantial mitigation potential. We estimated global 2023 methane emissions from energy sector point sources using the high spatial resolution GHGSat satellite constellation. GHGSat detected 8.30 ± 0.24 million tonnes per year of methane emissions from 3114 emission sites. Detected oil and gas– and coal-emitting sites were found to be emitting 16 and 48% of the time， we report the observation of Shapiro steps in a driven Josephson junction in a gas of ultracold atoms. We demonstrate that the steps exhibit universal features and provide insight into the microscopic dissipative dynamics that we directly observe in the experiment. We find that the steps are directly connected to phonon emission and nucleation of solitonic excitations。
