Monitoring atmospheric methane by Environment and Climate Change Canada
Dr. Vogel is a research scientist in ECCC’s Climate Research Division since 2017 and investigates greenhouse gas emissions using atmospheric observations. In recent weeks, the global attention has been drawn towards methane mitigation. In this week’s seminar, Dr. Vogel will review ECCC research efforts on methane sources in Canada from provincial to site-scale. In many cases methane emissions have been found to follow a power-law with a small amount of super-emitters overly contributing to total

Constraining Equilibrium Climate Sensitivity through Simulation of Past Extreme Climates
Equilibrium climate sensitivity (ECS), the global surface temperature increase to the radiative forcing caused by a doubling of atmospheric CO2 concentration, is the single number that describes the severity of long-term climate change. Global climate models have been an important tool for estimating ECS and understanding the relevant physics. Recent Coupled Model Intercomparison Project phase 6 (CMIP6) models simulated an ECS range of 1.8–5.6 ℃, with an upper end substantially higher than previ
