EXtremeClimTwin: Building capacity on climate extremes through cooperation

Increasing heat extremes, reduced summer precipitation and higher rainfall intensities are some of the climate change impacts facing the Western Balkans. To strengthen local researchers’ ability to understand the current and coming changes in climate extremes, CICERO researchers are involved in an EU funded capacity building project with the University of Novi Sad in Serbia.

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.

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.
