Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere in a changing climate is critical to better understand global cycle, support development policies, project future change. Here we describe synthesize datasets methodology quantify five major components budget uncertainties. Fossil CO2 (EFOS) are based on energy statistics cement production data, while from land-use change (ELUC), mainly...

ABSTRACT Gas exchange measurements were carried out on ash and oak trees in a forest plantation during three whole growing seasons characterized by different water availability (2001, 2002 2003). A quantitative limitation analysis was applied to estimate the effects of drought leaf ontogeny stomatal ( S L ) non‐stomatal limitations NS light‐saturated net photosynthesis max ), relative seasonal maximum rates obtained under conditions optimal soil content. Furthermore, based combined gas...

Abstract There is a clear need for transformative change in the land management and food production sectors to address global challenges of climate mitigation, adaptation, combatting degradation desertification, delivering security (referred hereafter as “land challenges”). We assess potential 40 practices these find that: Nine options deliver medium large benefits all four challenges. A further two have no estimates but other Five mitigation (>3 Gt CO 2 eq/year) without adverse impacts...
Land-based climate mitigation measures have gained significant attention and importance in public private sector policies. Building on previous studies, we refine update the potentials for 20 land-based >200 countries five regions, comparing "bottom-up" sectoral estimates with integrated assessment models (IAMs). We also assess implementation feasibility at country level. Cost-effective (available up to $100/tCO2 eq) is 8-13.8 GtCO2 eq yr-1 between 2020 2050, bottom end of this range...
Abstract. In support of the global stocktake Paris Agreement on climate change, this study presents a comprehensive framework to process results an ensemble atmospheric inversions in order make their net ecosystem exchange (NEE) carbon dioxide (CO2) flux suitable for evaluating national greenhouse gas inventories (NGHGIs) submitted by countries United Nations Framework Convention Climate Change (UNFCCC). From we also deduced anthropogenic methane (CH4) emissions regrouped into fossil and...
The mitigation potential of vegetation-driven biophysical effects is strongly influenced by the background climate and will therefore be global warming. Based on an ensemble remote sensing datasets, here we first estimate temperature sensitivities to changes in leaf area over period 2003-2014 as a function key environmental drivers. These are then used predict induced future dynamics under four scenarios. Results show that 2100, high-emission scenario, greening likely mitigate land warming...
Abstract. As the focus of climate policy shifts from pledges to implementation, there is a growing need track progress on change mitigation at country level, particularly for land-use sector. Despite new tools and models providing unprecedented monitoring opportunities, striking differences remain in estimations anthropogenic CO2 fluxes between, one hand, national greenhouse gas inventories (NGHGIs) used assess compliance with targets under Paris Agreement and, other Global Carbon Budget...
Fire has a role in ecosystem services; naturally produced wildfires are important for the sustainability of many terrestrial biomes and fire is one nature's primary carbon-cycling mechanisms. Under warming climate, it likely that frequency severity will increase. There some evidence activity may already be increasing Western U.S. forests recent exceptionally intense events, such as Australian Black Saturday fires 2009 Russian 2010, highlight devastation associated with extreme weather. The...
Abstract Overviewing the European carbon (C), greenhouse gas (GHG), and non‐GHG fluxes, gross primary productivity (GPP) is about 9.3 Pg yr −1 , fossil fuel imports are 1.6 .

Gas exchange was measured in a forest plantation dominated by Fraxinus angustifolia Vahl. and Quercus robur L. northern Italy, over three growing seasons that differed water availability (2001, 2002 2003). The objectives were to: (1) determine variability the photosynthetic parameters Vcmax (maximum carboxylation capacity) Jmax rate of electron transport) relation to species, leaf ontogeny drought; (2) assess potential photosynthesis–nitrogen relationship for estimating capacity. Marked...
A common paradigm when the reduction of emissions from deforestations is estimated for purpose promoting it as a mitigation option in context United Nations Framework Convention on Climate Change (UNFCCC) that high uncertainties input data—i.e., area change and C stock change/area—may seriously undermine credibility estimates therefore reduced deforestation option.
Land use and land cover change (LULCC) affects the climate through both biogeochemical (BGC) biophysical (BPH) mechanisms. While BGC effects are assessed at global scale heart of treaties such as Paris Agreement, BPH totally absent despite their increasingly recognized impact, especially local scale. This stems from complexity in characterizing impacts scale, which makes it impractical to offer clear advices for development policies. To overcome this barrier, we built a prototype an...
Abstract. National, regional and global CO2 emissions removals from forests were estimated for the period 1990–2020 using as input country reports of Global Forest Resources Assessment 2020. The new Food Agriculture Organization United Nations (FAO) estimates, based on a simple carbon stock change approach, update published information net in relation to (a) forest conversion (b) land. Results show significant reduction over study period, mean 4.3 1991–2000 2.9 Gt yr−1 2016–2020. At same...
