Integrating sudden and extreme changes in the anthropogenic and biogenic greenhouse gases

Climate change is causing abrupt changes in greenhouse gas (GHG) cycles, either by altering biogenic fluxes, or changes in anthropogenic emissions as witnessed during the Covid-19 pandemic. Hence, we need to integrate all feedbacks taking place between the climate system and the GHG cycles. While the Covid-19 shutdown led to 17% reduction in daily global CO2 emissions, large forest-fires erupted across the Americas, Australia and the Arctic circle in 2019 and 2020, releasing greenhouse gases and destroyed forests which take up CO2. Global warming leads to early, long summers causing droughts and forests fires. 2018 was one of the driest summers in Europe, resulting in forest carbon sinks decreasing or even turning forests into sources in some cases. Anomalously high solar radiation also led to extreme algal blooms in the Baltic Sea. Thus the feedbacks between the climate system and GHG cycles are multi-dimensional and complex, and need inter-disciplinary research.
For this session, we invite abstracts from observational and modeling studies examining and integrating extreme changes in GHGs (biogenic and/or anthropogenic) and their feedbacks to the climate system. For example (but not limited to):
1. Aftermath of COVID-19 lockdown, emerging into the new normal.
2. Effect of forest fires in 2019 and 2020 on regional to global scale.
3. Warm and wet winter of 2019/2020 and its impact on terrestrial and marine ecosystems.
4. Dry and hot European summers and subsequent droughts since 2018.
