This topic aims at filling fundamental gaps in our understanding of Earth system, focussing on greenhouse gas (GHG) fluxes and Earth system feedbacks, the behaviour of radiative forcers (including their pre-cursors), and efforts to stabilise global temperature through deployment of carbon dioxide (CO2) removal approaches.
Actions should improve scientific understanding in only one of the following areas:
a) Greenhouse gas fluxes and Earth system feedbacks
b) Global warming contribution of different, non-CO2 radiative forcers
c) Climate and Earth system responses to climate neutrality and net negative emissions
– Knowledge in the addressed areas through increasing the use of high quality data
– Improved projections of climate change
– Improved understanding of how innovative mitigation actions can help stabilise global temperature
– Improvements in Earth system models, climate services and other forms of downstream use.
