Climate-Carbon Interactions in the Current Century

Descrizione del progetto

Nuovi modelli più accurati del modo in cui il carbonio influisce sui cambiamenti climatici

I feedback sui cambiamenti climatici sono importanti per comprendere il riscaldamento globale in quanto i processi di feedback possono amplificare o ridurre l’effetto della forzatura climatica. Essi svolgono quindi un ruolo importante nel determinare la sensibilità climatica e il futuro stato climatico. Il progetto CCiCC, finanziato dall’UE, mira a ridurre l’incertezza nella comprensione quantitativa delle interazioni e dei feedback carbonio-clima. Gli scienziati quantificheranno i processi fondamentali che regolano il sistema associato carbonio-clima e utilizzeranno i vincoli osservativi per fornire proiezioni a lungo termine del clima in risposta alle emissioni antropogeniche. Il progetto fornirà inoltre raccomandazioni politiche sulle vie di emissione dell’anidride carbonica. Analisi e dati CCiCC aiuteranno gli esperti a valutare meglio in che modo le emissioni di anidride carbonica influenzano il cambiamento climatico.

Obiettivo

4C addresses the crucial knowledge gap in the climate sensitivity to carbon dioxide emissions, by reducing uncertainty in our quantitative understanding of carbon-climate interactions and feedbacks. This will be achieved through innovative integration of models and observations, providing new constraints on modelled carbon-climate interactions and climate projections, and supporting IPCC assessments and policy objectives. To meet this objective, 4C will (a) provide a step change in our ability to quantify the key processes regulating the coupled carbon-climate system, (b) use observational constraints and improved processes understanding to provide multi-model near-term predictions and long-term projections of the climate in response to anthropogenic emissions, and (c) deliver policy-relevant carbon dioxide emission pathways consistent with the UNFCCC Paris Agreement (PA) goals.
To achieve its goals, 4C will develop and use: state-of-the-art Earth System Models (ESMs) including biogeochemical processes not included in previous IPCC reports; novel observations to constrain the contemporary carbon cycle and its natural variability; ESM-based decadal predictions including carbon-climate feedbacks and novel initialisation methods; novel emergent constraints and weighting methods to reduce uncertainty in carbon cycle and climate projections; and novel climate scenarios following adaptive CO2 emission pathways.
4C will support two central elements of the PA. First, the PA global stocktakes, by providing policy-relevant predictions of atmospheric CO2 and climate in response to the national determined contributions. Second, the PA ambitions to keep global warming well below 2°C, by providing robust estimates of the remaining carbon budgets and available pathways. 4C will bring together leading European groups on climate modelling and on carbon cycle research, uniquely securing Europe’s leadership in actionable science needed for the IPCC assessments.
