The annual Carbon Outlooks released by the EU-funded 4C project provide an overview of the evolution of the CO2 emissions during the past year, prepared in collaboration with the Global Carbon Project.
The ocean is an important carbon sink, taking up CO2 that is released into the atmosphere by anthropogenic activities, such as fossil fuel burning and lang use changes. It is estimated that the ocean takes up about 37% of fossil fuel CO2 emissions.
The European Geosciences Union (EGU) is hosting its yearly General Assembly on 23-27 May 2022. The conference brings together scientists from the Earth, planetary and space science fields to present and discuss the latest research in their fields, in particular targeting early-career scientists.
A number of 4C researchers are participating in the event, presenting their findings on carbon cycle research and climate predictions. Policy-relevant results that can help reduce uncertainties and move towards a net-zero world are also showcased.
The 4C Carbon Outlook, released in November 2021, is warning that stronger climate policies are needed to trigger the necessary short-term action to reduce CO2 emissions sufficiently in the coming decade to keep the option for 1.5°C alive.
The carbon budget is a powerful concept developed in the last decade to assess how much additional carbon dioxide (CO2) humans can emit before a temperature target will be reached with a given probability. It provides critical knowledge to policymakers in order to prepare appropriate mitigation plans.
Better understanding the relationship between the temperature increase and cumulative CO2 emissions is crucial in determining how the global mean temperature will change after emissions reach zero.
