Large uncertainty in warming outcomes of current policies and emission pledges

During the recent Glasgow Climate Conference (COP26) there was a lot of focus on the climate outcomes of new climate policy pledges. A new analysis shows that these outcomes are more uncertain then often assumed.

How do gases and particles affect turbulence in the lower atmosphere?

Global CO2 emissions return to near pre-COVID pandemic levels

Global fossil CO2 emissions are expected to grow 4.9% in 2021, nearly offsetting the 5.4% decline in 2020 due the COVID restrictions. Coal and gas use rebounded strongly to exceed 2019 levels, while oil use remains suppressed, suggesting strong policy action is needed to avoid continued emissions growth in 2022.

CICERO is helping to develop a new global emissions monitoring service (CoCO2)

Together with 24 partners in 14 countries, CICERO is working to develop a European operational service for monitoring global greenhouse gas emissions, as part of the EU-funded project Prototype system for a Copernicus CO2 service, the CoCO2 project.

Global temperatures are rising due to the accumulation of greenhouse gases in the atmosphere. In addition to increasing greenhouse gas emissions, human activity has changed the composition of particles in the atmosphere. These have masked some of the warming caused by the greenhouse gases. How large is this cooling effect, and how has it changed over time?
