Global Carbon Budget 2020

Publication ID: pub.1133424713

Publication date: 11/12/2020

Keywords: Anthropogenic; Atmosphere; Carbon Budget; Carbon Cycle; Carbon Dioxide(CO2); Climate Policies; Data; Emissions; Global; Land-use Change; Models; Ocean; Sink; Terrestrial Biosphere; Uncertainties

Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere in a changing climate – the “global carbon budget” – is important to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe and synthesize data […]

Recent global decline of CO2 fertilization effects on vegetation photosynthesis

Publication ID: pub.1133406468

Publication date: 10/12/2020

Keywords: Atmosphere; Carbon Cycle; Carbon Dioxide; Global; Global Warming; Photosynthesis

The enhanced vegetation productivity driven by increased concentrations of carbon dioxide (CO2) [i.e., the CO2 fertilization effect (CFE)] sustains an important negative feedback on climate warming, but the temporal dynamics of CFE remain unclear. Using multiple long-term satellite- and ground-based datasets, we showed that global CFE has declined across most terrestrial regions of the globe […]

Expert assessment of future vulnerability of the global peatland carbon sink

Publication ID: pub.1133282935

Publication date: 07/12/2020

Keywords: Carbon Balance; Carbon Cycle; Carbon Stocks; Climate Change; Earth System Models; Global; Impact and Mitigation; Modelling Frameworks; Peatland Carbon Sink; Vulnerability

The carbon balance of peatlands is predicted to shift from a sink to a source this century. However, peatland ecosystems are still omitted from the main Earth system models that are used for future climate change projections, and they are not considered in integrated assessment models that are used in impact and mitigation studies. By […]

Opportunities and challenges in using remaining carbon budgets to guide climate policy

Publication ID: pub.1132978481

Publication date: 30/11/2020

Keywords: Calculation; Carbon Budget; Climate Policies; Estimates; Global; Global Warming; Low-carbon Economy; Mitigation Target; Policy Implications; Temperature Target; Transition; Uncertainties

The remaining carbon budget represents the total amount of CO2 that can still be emitted in the future while limiting global warming to a given temperature target. Remaining carbon budget estimates range widely, however, and this uncertainty can be used to either trivialize the most ambitious mitigation targets by characterizing them as impossible, or to […]

Boreal permafrost thaw amplified by fire disturbance and precipitation increases

Publication ID: pub.1131478266

Publication date: 19/11/2020

Keywords: Leaf Area Index; North America; Permafrost; Thaw; Thermal Modelling

Permafrost soils store huge amounts of organic carbon, which could be released if climate change promotes thaw. Currently, modelling studies predict that thaw in boreal regions is mainly sensitive to warming, rather than changes in precipitation or vegetation cover. We evaluate this conclusion for North American boreal forests using a detailed process-based model parameterised and […]
