AbstractBiomass burning (BB) is a major source of aerosols that remain the most uncertain components of the global radiative forcing. Current global models have great difficulty matching observed aerosol optical depth (AOD) over BB regions. A common solution to address modelled AOD biases is scaling BB emissions. Using the relationship from an ensemble of aerosol models and satellite observations, we show that the bias in aerosol modelling results primarily from incorrect lifetimes and underestimated mass extinction coefficients. In turn, these biases seem to be related to incorrect precipitation and underestimated particle sizes. We further show that boosting BB emissions to correct AOD biases over the source region causes an overestimation of AOD in the outflow from Africa by 48%, leading to a double warming effect compared with when biases are simultaneously addressed for both aforementioned factors. Such deviations are particularly concerning in a warming future with increasing emissions from fires.

Un système d'observation et d'analyse du carbone intégré à l'échelle mondiale est nécessaire pour améliorer la compréhension fondamentale du cycle mondial du carbone, pour améliorer notre capacité à projeter les changements futurs et pour vérifier l'efficacité des politiques visant à réduire les émissions de gaz à effet de serre et à augmenter la séquestration du carbone. La construction d'un système intégré d'observation du carbone nécessite des avancées transformationnelles du cadre exploratoire clairsemé existant vers un système dense, robuste et durable dans toutes ses composantes : les émissions anthropiques, l'atmosphère, l'océan et la biosphère terrestre. L'objectif de cette étude est d'identifier l'état actuel des observations de carbone et les besoins d'un système mondial intégré d'observation du carbone qui peut être construit au cours de la prochaine décennie. Une conclusion clé est l'expansion substantielle (de plusieurs ordres de grandeur) des réseaux d'observation au sol nécessaires pour atteindre la haute résolution spatiale pour les flux de CO2 et de CH4 et pour les stocks de carbone afin de répondre aux objectifs politiques pertinents et d'attribuer les changements de flux aux processus sous-jacents dans chaque région. Afin d'établir des diagnostics de flux et de stocks sur des zones éloignées telles que les océans du sud, les forêts tropicales et l'Arctique, les observations in situ devront être complétées par des mesures de télédétection. La télédétection offre l'avantage d'une couverture spatiale dense et de revisites fréquentes. Un défi clé consiste à amener les mesures de télédétection à un niveau de cohérence et de précision à long terme afin qu'elles puissent être efficacement combinées dans des modèles pour réduire les incertitudes, en synergie avec les données au sol. Apporter des contraintes d'observation strictes sur les émissions de combustibles fossiles et de changement d'affectation des terres sera le plus grand défi pour le déploiement d'un système intégré d'observation du carbone pertinent pour les politiques. Cela nécessitera des données in situ et de télédétection à une résolution et une densité beaucoup plus élevées que celles actuellement atteintes pour les flux naturels, bien que sur une petite superficie (villes, sites industriels, centrales électriques), ainsi que l'inclusion de mesures indirectes de CO2 de combustibles fossiles telles que le radiocarbone dans les traceurs de combustion de CO2 et de carbone. En outre, un système de surveillance du carbone pertinent pour les politiques devrait également fournir des mécanismes pour concilier les estimations des flux régionaux descendants (basés sur l'atmosphère) et ascendants (basés sur la surface) sur toute la gamme des échelles spatiales et temporelles pertinentes pour les politiques d'atténuation. Le succès du système reposera sur des engagements à long terme en matière de suivi, sur une meilleure collaboration internationale pour combler les lacunes dans les observations actuelles, sur des efforts soutenus pour améliorer l'accès aux différents flux de données et rendre les bases de données interopérables, et sur l'étalonnage de chaque composante du système à des échelles internationales convenues. Resumen. Se necesita un sistema de observación y análisis de carbono integrado a nivel mundial para mejorar la comprensión fundamental del ciclo global del carbono, para mejorar nuestra capacidad de proyectar cambios futuros y para verificar la efectividad de las políticas destinadas a reducir las emisiones de gases de efecto invernadero y aumentar el secuestro de carbono. Construir un sistema integrado de observación de carbono requiere avances transformacionales desde el marco exploratorio escaso existente hacia un sistema denso, robusto y sostenido en todos los componentes: las emisiones antropogénicas, la atmósfera, el océano y la biosfera terrestre. El objetivo de este estudio es identificar el estado actual de las emisiones de carbono y las necesidades de un sistema global integrado de emisiones de carbono que pueda construirse en la próxima década. Una conclusión clave es la expansión sustancial (en varios órdenes de magnitud) de las redes de observación terrestres necesarias para alcanzar la alta resolución espacial para los flujos de CO2 y CH4, y para las reservas de carbono para abordar los objetivos relevantes para las políticas y atribuir los cambios de flujo a los procesos subyacentes en cada región. Para establecer diagnósticos de flujo y stock en áreas remotas como los océanos del sur, los bosques tropicales y el Ártico, las observaciones in situ deberán complementarse con mediciones de teledetección. La teledetección ofrece la ventaja de una cobertura espacial densa y una revisión frecuente. Un desafío clave es llevar las mediciones de teledetección a un nivel de consistencia y precisión a largo plazo para que puedan combinarse de manera eficiente en modelos para reducir las incertidumbres, en sinergia con los datos basados en tierra. Traer restricciones observacionales estrictas sobre las emisiones de combustibles fósiles y el cambio en el uso de la tierra será el mayor desafío para el despliegue de un sistema integrado de observación de carbono relevante para las políticas. Esto requerirá datos in situ y teledetectados con una resolución y densidad mucho más altas que las que se logran actualmente para los flujos naturales, aunque en una pequeña superficie de tierra (ciudades, sitios industriales, centrales eléctricas), así como la inclusión de mediciones indirectas de CO2 de combustibles fósiles, como el radiocarbono en CO2 y los trazadores de combustión de combustibles de carbono. Además, un sistema de monitoreo de carbono relevante para las políticas también debe proporcionar mecanismos para conciliar las estimaciones regionales de flujo de arriba hacia abajo (basadas en la atmósfera) y de abajo hacia arriba (basadas en la superficie) en toda la gama de escalas espaciales y temporales relevantes para las políticas de mitigación. El éxito del sistema dependerá de los compromisos a largo plazo con el monitoreo, de una mejor colaboración internacional para llenar los vacíos en las observaciones actuales, de esfuerzos sostenidos para mejorar el acceso a los diferentes flujos de datos y hacer que las bases de datos sean interoperables, y de la calibración de cada componente del sistema a escalas internacionales acordadas. Abstract. A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of the global carbon cycle, to improve our ability to project future changes, and to verify the effectiveness of policies aiming to reduce greenhouse gas emissions and increase carbon sequestration. Building an integrated carbon observation system requires transformational advances from the existing sparse, exploratory framework towards a dense, robust, and sustained system in all components: anthropogenic emissions, the atmosphere, the ocean, and the terrestrial biosphere. The goal of this study is to identify the current state of carbon observations and needs for a global integrated carbon observation system that can be built in the next decade. A key conclusion is the substantial expansion (by several orders of magnitude) of the ground-based observation networks required to reach the high spatial resolution for CO2 and CH4 fluxes, and for carbon stocks for addressing policy relevant objectives, and attributing flux changes to underlying processes in each region. In order to establish flux and stock diagnostics over remote areas such as the southern oceans, tropical forests and the Arctic, in situ observations will have to be complemented with remote-sensing measurements. Remote sensing offers the advantage of dense spatial coverage and frequent revisit. A key challenge is to bring remote sensing measurements to a level of long-term consistency and accuracy so that they can be efficiently combined in models to reduce uncertainties, in synergy with ground-based data. Bringing tight observational constraints on fossil fuel and land use change emissions will be the biggest challenge for deployment of a policy-relevant integrated carbon observation system. This will require in-situ and remotely sensed data at much higher resolution and density than currently achieved for natural fluxes, although over a small land area (cities, industrial sites, power plants), as well as the inclusion of fossil fuel CO2 proxy measurements such as radiocarbon in CO2 and carbon-fuel combustion tracers. Additionally, a policy relevant carbon monitoring system should also provide mechanisms for reconciling regional top-down (atmosphere-based) and bottom-up (surface-based) flux estimates across the range of spatial and temporal scales relevant to mitigation policies. The success of the system will rely on long-term commitments to monitoring, on improved international collaboration to fill gaps in the current observations, on sustained efforts to improve access to the different data streams and make databases inter-operable, and on the calibration of each component of the system to agreed-upon international scales. الخلاصة. هناك حاجة إلى نظام متكامل عالميًا لمراقبة الكربون وتحليله لتحسين الفهم الأساسي لدورة الكربون العالمية، وتحسين قدرتنا على توقع التغييرات المستقبلية، والتحقق من فعالية السياسات التي تهدف إلى الحد من انبعاثات غازات الدفيئة وزيادة عزل الكربون. يتطلب بناء نظام متكامل لمراقبة الكربون تقدمًا تحويليًا من الإطار الاستكشافي المتناثر الحالي نحو نظام كثيف وقوي ومستدام في جميع المكونات: الانبعاثات البشرية المنشأ والغلاف الجوي والمحيطات والمحيط الحيوي الأرضي. الهدف من هذه الدراسة هو تحديد الوضع الحالي لملاحظات الكربون والاحتياجات لنظام عالمي متكامل لمراقبة الكربون يمكن بناؤه في العقد المقبل. الاستنتاج الرئيسي هو التوسع الكبير (بعدة مرات من حيث الحجم) لشبكات المراقبة الأرضية المطلوبة للوصول إلى الاستبانة المكانية العالية لتدفقات ثاني أكسيد الكربون والميثان، ولمخزونات الكربون لمعالجة الأهداف ذات الصلة بالسياسات، وعزو تغييرات التدفق إلى العمليات الأساسية في كل منطقة. من أجل إنشاء تشخيصات التدفق والأرصدة في المناطق النائية مثل المحيطات الجنوبية والغابات الاستوائية والقطب الشمالي، يجب استكمال الملاحظات في الموقع بقياسات الاستشعار عن بعد. يوفر الاستشعار عن بعد ميزة التغطية المكانية الكثيفة وإعادة الزيارة المتكررة. ويتمثل أحد التحديات الرئيسية في الوصول بقياسات الاستشعار عن بعد إلى مستوى من الاتساق والدقة على المدى الطويل بحيث يمكن دمجها بكفاءة في نماذج للحد من أوجه عدم اليقين، بالتآزر مع البيانات الأرضية. سيكون فرض قيود صارمة على مراقبة الوقود الأحفوري وانبعاثات تغير استخدام الأراضي هو التحدي الأكبر أمام نشر نظام متكامل لمراقبة الكربون ذي صلة بالسياسات. وسيتطلب ذلك بيانات في الموقع ومستشعرة عن بعد بدقة وكثافة أعلى بكثير مما هو متحقق حاليًا للتدفقات الطبيعية، على الرغم من أنها على مساحة أرض صغيرة (المدن والمواقع الصناعية ومحطات الطاقة)، بالإضافة إلى تضمين قياسات وكيل ثاني أكسيد الكربون للوقود الأحفوري مثل الكربون المشع في ثاني أكسيد الكربون وتتبع احتراق الوقود الكربوني. بالإضافة إلى ذلك، يجب أن يوفر نظام رصد الكربون ذي الصلة بالسياسة أيضًا آليات للتوفيق بين تقديرات التدفق الإقليمية من أعلى إلى أسفل (القائمة على الغلاف الجوي) ومن أسفل إلى أعلى (السطحية) عبر نطاق المقاييس المكانية والزمنية ذات الصلة بسياسات التخفيف. سيعتمد نجاح النظام على الالتزامات طويلة الأجل بالرصد، وعلى تحسين التعاون الدولي لسد الثغرات في الملاحظات الحالية، وعلى الجهود المستمرة لتحسين الوصول إلى تدفقات البيانات المختلفة وجعل قواعد البيانات قابلة للتشغيل المتبادل، وعلى معايرة كل مكون من مكونات النظام وفقًا للنطاقات الدولية المتفق عليها.

Drought as an intermittent disturbance of the water cycle interacts with the carbon cycle differently than the ‘gradual’ climate change. During drought plants respond physiologically and structurally to prevent excessive water loss according to species-specific water use strategies. This has consequences for carbon uptake by photosynthesis and release by total ecosystem respiration. After a drought the disturbances in the reservoirs of moisture, organic matter and nutrients in the soil and carbohydrates in plants lead to longer-term effects in plant carbon cycling, and potentially mortality. Direct and carry-over effects, mortality and consequently species competition in response to drought are strongly related to the survival strategies of species. Here we review the state of the art of the understanding of the relation between soil moisture drought and the interactions with the carbon cycle of the terrestrial ecosystems. We argue that plant strategies must be given an adequate role in global vegetation models if the effects of drought on the carbon cycle are to be described in a way that justifies the interacting processes.

Abstract. Biomass burning represents an important source of atmospheric aerosols and greenhouse gases, yet little is known about its interannual variability or the underlying mechanisms regulating this variability at continental to global scales. Here we investigated fire emissions during the 8 year period from 1997 to 2004 using satellite data and the CASA biogeochemical model. Burned area from 2001–2004 was derived using newly available active fire and 500 m. burned area datasets from MODIS following the approach described by Giglio et al. (2006). ATSR and VIRS satellite data were used to extend the burned area time series back in time through 1997. In our analysis we estimated fuel loads, including organic soil layer and peatland fuels, and the net flux from terrestrial ecosystems as the balance between net primary production (NPP), heterotrophic respiration (Rh), and biomass burning, using time varying inputs of precipitation (PPT), temperature, solar radiation, and satellite-derived fractional absorbed photosynthetically active radiation (fAPAR). For the 1997–2004 period, we found that on average approximately 58 Pg C year−1 was fixed by plants as NPP, and approximately 95% of this was returned back to the atmosphere via Rh. Another 4%, or 2.5 Pg C year−1 was emitted by biomass burning; the remainder consisted of losses from fuel wood collection and subsequent burning. At a global scale, burned area and total fire emissions were largely decoupled from year to year. Total carbon emissions tracked burning in forested areas (including deforestation fires in the tropics), whereas burned area was largely controlled by savanna fires that responded to different environmental and human factors. Biomass burning emissions showed large interannual variability with a range of more than 1 Pg C year−1, with a maximum in 1998 (3.2 Pg C year−1) and a minimum in 2000 (2.0 Pg C year−1).

Drainage of peatlands and deforestation have led to large-scale fires in equatorial Asia, affecting regional air quality and global concentrations of greenhouse gases. Here we used several sources of satellite data with biogeochemical and atmospheric modeling to better understand and constrain fire emissions from Indonesia, Malaysia, and Papua New Guinea during 2000–2006. We found that average fire emissions from this region [128 ± 51 (1σ) Tg carbon (C) year −1 , T = 10 12 ] were comparable to fossil fuel emissions. In Borneo, carbon emissions from fires were highly variable, fluxes during the moderate 2006 El Niño more than 30 times greater than those during the 2000 La Niña (and with a 2000–2006 mean of 74 ± 33 Tg C yr −1 ). Higher rates of forest loss and larger areas of peatland becoming vulnerable to fire in drought years caused a strong nonlinear relation between drought and fire emissions in southern Borneo. Fire emissions from Sumatra showed a positive linear trend, increasing at a rate of 8 Tg C year −2 (approximately doubling during 2000–2006). These results highlight the importance of including deforestation in future climate agreements. They also imply that land manager responses to expected shifts in tropical precipitation may critically determine the strength of climate–carbon cycle feedbacks during the 21st century.

Hansen; Joanna Isobel House; C. Le Quéré; Julia Pongratz; Julia Pongratz; G. R. van der Werf; Navin Ramankutty; Richard A. Houghton; Ruth DeFries;Abstract. The net flux of carbon from land use and land-cover change (LULCC) accounted for 12.5% of anthropogenic carbon emissions from 1990 to 2010. This net flux is the most uncertain term in the global carbon budget, not only because of uncertainties in rates of deforestation and forestation, but also because of uncertainties in the carbon density of the lands actually undergoing change. Furthermore, there are differences in approaches used to determine the flux that introduce variability into estimates in ways that are difficult to evaluate, and not all analyses consider the same types of management activities. Thirteen recent estimates of net carbon emissions from LULCC are summarized here. In addition to deforestation, all analyses considered changes in the area of agricultural lands (croplands and pastures). Some considered, also, forest management (wood harvest, shifting cultivation). None included emissions from the degradation of tropical peatlands. Means and standard deviations across the thirteen model estimates of annual emissions for the 1980s and 1990s, respectively, are 1.14 ± 0.23 and 1.12 ± 0.25 Pg C yr−1 (1 Pg = 1015 g carbon). Four studies also considered the period 2000–2009, and the mean and standard deviations across these four for the three decades are 1.14 ± 0.39, 1.17 ± 0.32, and 1.10 ± 0.11 Pg C yr−1. For the period 1990–2009 the mean global emissions from LULCC are 1.14 ± 0.18 Pg C yr−1. The standard deviations across model means shown here are smaller than previous estimates of uncertainty as they do not account for the errors that result from data uncertainty and from an incomplete understanding of all the processes affecting the net flux of carbon from LULCC. Although these errors have not been systematically evaluated, based on partial analyses available in the literature and expert opinion, they are estimated to be on the order of ± 0.5 Pg C yr−1.

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 sets and methodology to quantify the five major components of the global carbon budget and their uncertainties. Fossil CO2 emissions (EFOS) are based on energy statistics and cement production data, while emissions from land-use change (ELUC), mainly deforestation, are based on land use and land-use change data and bookkeeping models. Atmospheric CO2 concentration is measured directly and its growth rate (GATM) is computed from the annual changes in concentration. The ocean CO2 sink (SOCEAN) and terrestrial CO2 sink (SLAND) are estimated with global process models constrained by observations. The resulting carbon budget imbalance (BIM), the difference between the estimated total emissions and the estimated changes in the atmosphere, ocean, and terrestrial biosphere, is a measure of imperfect data and understanding of the contemporary carbon cycle. All uncertainties are reported as ±1σ. For the last decade available (2010–2019), EFOS was 9.6 ± 0.5 GtC yr−1 excluding the cement carbonation sink (9.4 ± 0.5 GtC yr−1 when the cement carbonation sink is included), and ELUC was 1.6 ± 0.7 GtC yr−1. For the same decade, GATM was 5.1 ± 0.02 GtC yr−1 (2.4 ± 0.01 ppm yr−1), SOCEAN 2.5 ± 0.6 GtC yr−1, and SLAND 3.4 ± 0.9 GtC yr−1, with a budget imbalance BIM of −0.1 GtC yr−1 indicating a near balance between estimated sources and sinks over the last decade. For the year 2019 alone, the growth in EFOS was only about 0.1 % with fossil emissions increasing to 9.9 ± 0.5 GtC yr−1 excluding the cement carbonation sink (9.7 ± 0.5 GtC yr−1 when cement carbonation sink is included), and ELUC was 1.8 ± 0.7 GtC yr−1, for total anthropogenic CO2 emissions of 11.5 ± 0.9 GtC yr−1 (42.2 ± 3.3 GtCO2). Also for 2019, GATM was 5.4 ± 0.2 GtC yr−1 (2.5 ± 0.1 ppm yr−1), SOCEAN was 2.6 ± 0.6 GtC yr−1, and SLAND was 3.1 ± 1.2 GtC yr−1, with a BIM of 0.3 GtC. The global atmospheric CO2 concentration reached 409.85 ± 0.1 ppm averaged over 2019. Preliminary data for 2020, accounting for the COVID-19-induced changes in emissions, suggest a decrease in EFOS relative to 2019 of about −7 % (median estimate) based on individual estimates from four studies of −6 %, −7 %, −7 % (−3 % to −11 %), and −13 %. Overall, the mean and trend in the components of the global carbon budget are consistently estimated over the period 1959–2019, but discrepancies of up to 1 GtC yr−1 persist for the representation of semi-decadal variability in CO2 fluxes. Comparison of estimates from diverse approaches and observations shows (1) no consensus in the mean and trend in land-use change emissions over the last decade, (2) a persistent low agreement between the different methods on the magnitude of the land CO2 flux in the northern extra-tropics, and (3) an apparent discrepancy between the different methods for the ocean sink outside the tropics, particularly in the Southern Ocean. This living data update documents changes in the methods and data sets used in this new global carbon budget and the progress in understanding of the global carbon cycle compared with previous publications of this data set (Friedlingstein et al., 2019; Le Quéré et al., 2018b, a, 2016, 2015b, a, 2014, 2013). The data presented in this work are available at https://doi.org/10.18160/gcp-2020 (Friedlingstein et al., 2020).

Rogers;Roughly 3% of the Earth's land surface burns annually, representing a critical exchange of energy and matter between the land and atmosphere via combustion. Fires range from slow smouldering peat fires, to low-intensity surface fires, to intense crown fires, depending on vegetation structure, fuel moisture, prevailing climate, and weather conditions. While the links between biogeochemistry, climate and fire are widely studied within Earth system science, these relationships are also mediated by fuels-namely plants and their litter-that are the product of evolutionary and ecological processes. Fire is a powerful selective force and, over their evolutionary history, plants have evolved traits that both tolerate and promote fire numerous times and across diverse clades. Here we outline a conceptual framework of how plant traits determine the flammability of ecosystems and interact with climate and weather to influence fire regimes. We explore how these evolutionary and ecological processes scale to impact biogeochemical and Earth system processes. Finally, we outline several research challenges that, when resolved, will improve our understanding of the role of plant evolution in mediating the fire feedbacks driving Earth system processes. Understanding current patterns of fire and vegetation, as well as patterns of fire over geological time, requires research that incorporates evolutionary biology, ecology, biogeography, and the biogeosciences.

T;Satellite fire products have the potential to construct inter‐annual time series of fire activity, but estimating area burned requires considering biases introduced by orbiting geometry, fire behavior, and the presence of clouds and smoke. Here we evaluated the performance of fire counts from the Advanced Thermal Scanning Radiometer (ATSR) for the boreal forest region using area burned information from other sources. We found ATSR detection rate varied between regions and different years, being higher during large fire years than during small fire years. The results show ATSR fire counts do not represent an unbiased sample of fire activity, and independent validation may be required prior to using this data set in studies of global emissions from biomass burning.

AbstractBiomass burning (BB) is a major source of aerosols that remain the most uncertain components of the global radiative forcing. Current global models have great difficulty matching observed aerosol optical depth (AOD) over BB regions. A common solution to address modelled AOD biases is scaling BB emissions. Using the relationship from an ensemble of aerosol models and satellite observations, we show that the bias in aerosol modelling results primarily from incorrect lifetimes and underestimated mass extinction coefficients. In turn, these biases seem to be related to incorrect precipitation and underestimated particle sizes. We further show that boosting BB emissions to correct AOD biases over the source region causes an overestimation of AOD in the outflow from Africa by 48%, leading to a double warming effect compared with when biases are simultaneously addressed for both aforementioned factors. Such deviations are particularly concerning in a warming future with increasing emissions from fires.

Un système d'observation et d'analyse du carbone intégré à l'échelle mondiale est nécessaire pour améliorer la compréhension fondamentale du cycle mondial du carbone, pour améliorer notre capacité à projeter les changements futurs et pour vérifier l'efficacité des politiques visant à réduire les émissions de gaz à effet de serre et à augmenter la séquestration du carbone. La construction d'un système intégré d'observation du carbone nécessite des avancées transformationnelles du cadre exploratoire clairsemé existant vers un système dense, robuste et durable dans toutes ses composantes : les émissions anthropiques, l'atmosphère, l'océan et la biosphère terrestre. L'objectif de cette étude est d'identifier l'état actuel des observations de carbone et les besoins d'un système mondial intégré d'observation du carbone qui peut être construit au cours de la prochaine décennie. Une conclusion clé est l'expansion substantielle (de plusieurs ordres de grandeur) des réseaux d'observation au sol nécessaires pour atteindre la haute résolution spatiale pour les flux de CO2 et de CH4 et pour les stocks de carbone afin de répondre aux objectifs politiques pertinents et d'attribuer les changements de flux aux processus sous-jacents dans chaque région. Afin d'établir des diagnostics de flux et de stocks sur des zones éloignées telles que les océans du sud, les forêts tropicales et l'Arctique, les observations in situ devront être complétées par des mesures de télédétection. La télédétection offre l'avantage d'une couverture spatiale dense et de revisites fréquentes. Un défi clé consiste à amener les mesures de télédétection à un niveau de cohérence et de précision à long terme afin qu'elles puissent être efficacement combinées dans des modèles pour réduire les incertitudes, en synergie avec les données au sol. Apporter des contraintes d'observation strictes sur les émissions de combustibles fossiles et de changement d'affectation des terres sera le plus grand défi pour le déploiement d'un système intégré d'observation du carbone pertinent pour les politiques. Cela nécessitera des données in situ et de télédétection à une résolution et une densité beaucoup plus élevées que celles actuellement atteintes pour les flux naturels, bien que sur une petite superficie (villes, sites industriels, centrales électriques), ainsi que l'inclusion de mesures indirectes de CO2 de combustibles fossiles telles que le radiocarbone dans les traceurs de combustion de CO2 et de carbone. En outre, un système de surveillance du carbone pertinent pour les politiques devrait également fournir des mécanismes pour concilier les estimations des flux régionaux descendants (basés sur l'atmosphère) et ascendants (basés sur la surface) sur toute la gamme des échelles spatiales et temporelles pertinentes pour les politiques d'atténuation. Le succès du système reposera sur des engagements à long terme en matière de suivi, sur une meilleure collaboration internationale pour combler les lacunes dans les observations actuelles, sur des efforts soutenus pour améliorer l'accès aux différents flux de données et rendre les bases de données interopérables, et sur l'étalonnage de chaque composante du système à des échelles internationales convenues. Resumen. Se necesita un sistema de observación y análisis de carbono integrado a nivel mundial para mejorar la comprensión fundamental del ciclo global del carbono, para mejorar nuestra capacidad de proyectar cambios futuros y para verificar la efectividad de las políticas destinadas a reducir las emisiones de gases de efecto invernadero y aumentar el secuestro de carbono. Construir un sistema integrado de observación de carbono requiere avances transformacionales desde el marco exploratorio escaso existente hacia un sistema denso, robusto y sostenido en todos los componentes: las emisiones antropogénicas, la atmósfera, el océano y la biosfera terrestre. El objetivo de este estudio es identificar el estado actual de las emisiones de carbono y las necesidades de un sistema global integrado de emisiones de carbono que pueda construirse en la próxima década. Una conclusión clave es la expansión sustancial (en varios órdenes de magnitud) de las redes de observación terrestres necesarias para alcanzar la alta resolución espacial para los flujos de CO2 y CH4, y para las reservas de carbono para abordar los objetivos relevantes para las políticas y atribuir los cambios de flujo a los procesos subyacentes en cada región. Para establecer diagnósticos de flujo y stock en áreas remotas como los océanos del sur, los bosques tropicales y el Ártico, las observaciones in situ deberán complementarse con mediciones de teledetección. La teledetección ofrece la ventaja de una cobertura espacial densa y una revisión frecuente. Un desafío clave es llevar las mediciones de teledetección a un nivel de consistencia y precisión a largo plazo para que puedan combinarse de manera eficiente en modelos para reducir las incertidumbres, en sinergia con los datos basados en tierra. Traer restricciones observacionales estrictas sobre las emisiones de combustibles fósiles y el cambio en el uso de la tierra será el mayor desafío para el despliegue de un sistema integrado de observación de carbono relevante para las políticas. Esto requerirá datos in situ y teledetectados con una resolución y densidad mucho más altas que las que se logran actualmente para los flujos naturales, aunque en una pequeña superficie de tierra (ciudades, sitios industriales, centrales eléctricas), así como la inclusión de mediciones indirectas de CO2 de combustibles fósiles, como el radiocarbono en CO2 y los trazadores de combustión de combustibles de carbono. Además, un sistema de monitoreo de carbono relevante para las políticas también debe proporcionar mecanismos para conciliar las estimaciones regionales de flujo de arriba hacia abajo (basadas en la atmósfera) y de abajo hacia arriba (basadas en la superficie) en toda la gama de escalas espaciales y temporales relevantes para las políticas de mitigación. El éxito del sistema dependerá de los compromisos a largo plazo con el monitoreo, de una mejor colaboración internacional para llenar los vacíos en las observaciones actuales, de esfuerzos sostenidos para mejorar el acceso a los diferentes flujos de datos y hacer que las bases de datos sean interoperables, y de la calibración de cada componente del sistema a escalas internacionales acordadas. Abstract. A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of the global carbon cycle, to improve our ability to project future changes, and to verify the effectiveness of policies aiming to reduce greenhouse gas emissions and increase carbon sequestration. Building an integrated carbon observation system requires transformational advances from the existing sparse, exploratory framework towards a dense, robust, and sustained system in all components: anthropogenic emissions, the atmosphere, the ocean, and the terrestrial biosphere. The goal of this study is to identify the current state of carbon observations and needs for a global integrated carbon observation system that can be built in the next decade. A key conclusion is the substantial expansion (by several orders of magnitude) of the ground-based observation networks required to reach the high spatial resolution for CO2 and CH4 fluxes, and for carbon stocks for addressing policy relevant objectives, and attributing flux changes to underlying processes in each region. In order to establish flux and stock diagnostics over remote areas such as the southern oceans, tropical forests and the Arctic, in situ observations will have to be complemented with remote-sensing measurements. Remote sensing offers the advantage of dense spatial coverage and frequent revisit. A key challenge is to bring remote sensing measurements to a level of long-term consistency and accuracy so that they can be efficiently combined in models to reduce uncertainties, in synergy with ground-based data. Bringing tight observational constraints on fossil fuel and land use change emissions will be the biggest challenge for deployment of a policy-relevant integrated carbon observation system. This will require in-situ and remotely sensed data at much higher resolution and density than currently achieved for natural fluxes, although over a small land area (cities, industrial sites, power plants), as well as the inclusion of fossil fuel CO2 proxy measurements such as radiocarbon in CO2 and carbon-fuel combustion tracers. Additionally, a policy relevant carbon monitoring system should also provide mechanisms for reconciling regional top-down (atmosphere-based) and bottom-up (surface-based) flux estimates across the range of spatial and temporal scales relevant to mitigation policies. The success of the system will rely on long-term commitments to monitoring, on improved international collaboration to fill gaps in the current observations, on sustained efforts to improve access to the different data streams and make databases inter-operable, and on the calibration of each component of the system to agreed-upon international scales. الخلاصة. هناك حاجة إلى نظام متكامل عالميًا لمراقبة الكربون وتحليله لتحسين الفهم الأساسي لدورة الكربون العالمية، وتحسين قدرتنا على توقع التغييرات المستقبلية، والتحقق من فعالية السياسات التي تهدف إلى الحد من انبعاثات غازات الدفيئة وزيادة عزل الكربون. يتطلب بناء نظام متكامل لمراقبة الكربون تقدمًا تحويليًا من الإطار الاستكشافي المتناثر الحالي نحو نظام كثيف وقوي ومستدام في جميع المكونات: الانبعاثات البشرية المنشأ والغلاف الجوي والمحيطات والمحيط الحيوي الأرضي. الهدف من هذه الدراسة هو تحديد الوضع الحالي لملاحظات الكربون والاحتياجات لنظام عالمي متكامل لمراقبة الكربون يمكن بناؤه في العقد المقبل. الاستنتاج الرئيسي هو التوسع الكبير (بعدة مرات من حيث الحجم) لشبكات المراقبة الأرضية المطلوبة للوصول إلى الاستبانة المكانية العالية لتدفقات ثاني أكسيد الكربون والميثان، ولمخزونات الكربون لمعالجة الأهداف ذات الصلة بالسياسات، وعزو تغييرات التدفق إلى العمليات الأساسية في كل منطقة. من أجل إنشاء تشخيصات التدفق والأرصدة في المناطق النائية مثل المحيطات الجنوبية والغابات الاستوائية والقطب الشمالي، يجب استكمال الملاحظات في الموقع بقياسات الاستشعار عن بعد. يوفر الاستشعار عن بعد ميزة التغطية المكانية الكثيفة وإعادة الزيارة المتكررة. ويتمثل أحد التحديات الرئيسية في الوصول بقياسات الاستشعار عن بعد إلى مستوى من الاتساق والدقة على المدى الطويل بحيث يمكن دمجها بكفاءة في نماذج للحد من أوجه عدم اليقين، بالتآزر مع البيانات الأرضية. سيكون فرض قيود صارمة على مراقبة الوقود الأحفوري وانبعاثات تغير استخدام الأراضي هو التحدي الأكبر أمام نشر نظام متكامل لمراقبة الكربون ذي صلة بالسياسات. وسيتطلب ذلك بيانات في الموقع ومستشعرة عن بعد بدقة وكثافة أعلى بكثير مما هو متحقق حاليًا للتدفقات الطبيعية، على الرغم من أنها على مساحة أرض صغيرة (المدن والمواقع الصناعية ومحطات الطاقة)، بالإضافة إلى تضمين قياسات وكيل ثاني أكسيد الكربون للوقود الأحفوري مثل الكربون المشع في ثاني أكسيد الكربون وتتبع احتراق الوقود الكربوني. بالإضافة إلى ذلك، يجب أن يوفر نظام رصد الكربون ذي الصلة بالسياسة أيضًا آليات للتوفيق بين تقديرات التدفق الإقليمية من أعلى إلى أسفل (القائمة على الغلاف الجوي) ومن أسفل إلى أعلى (السطحية) عبر نطاق المقاييس المكانية والزمنية ذات الصلة بسياسات التخفيف. سيعتمد نجاح النظام على الالتزامات طويلة الأجل بالرصد، وعلى تحسين التعاون الدولي لسد الثغرات في الملاحظات الحالية، وعلى الجهود المستمرة لتحسين الوصول إلى تدفقات البيانات المختلفة وجعل قواعد البيانات قابلة للتشغيل المتبادل، وعلى معايرة كل مكون من مكونات النظام وفقًا للنطاقات الدولية المتفق عليها.

Drought as an intermittent disturbance of the water cycle interacts with the carbon cycle differently than the ‘gradual’ climate change. During drought plants respond physiologically and structurally to prevent excessive water loss according to species-specific water use strategies. This has consequences for carbon uptake by photosynthesis and release by total ecosystem respiration. After a drought the disturbances in the reservoirs of moisture, organic matter and nutrients in the soil and carbohydrates in plants lead to longer-term effects in plant carbon cycling, and potentially mortality. Direct and carry-over effects, mortality and consequently species competition in response to drought are strongly related to the survival strategies of species. Here we review the state of the art of the understanding of the relation between soil moisture drought and the interactions with the carbon cycle of the terrestrial ecosystems. We argue that plant strategies must be given an adequate role in global vegetation models if the effects of drought on the carbon cycle are to be described in a way that justifies the interacting processes.

Abstract. Biomass burning represents an important source of atmospheric aerosols and greenhouse gases, yet little is known about its interannual variability or the underlying mechanisms regulating this variability at continental to global scales. Here we investigated fire emissions during the 8 year period from 1997 to 2004 using satellite data and the CASA biogeochemical model. Burned area from 2001–2004 was derived using newly available active fire and 500 m. burned area datasets from MODIS following the approach described by Giglio et al. (2006). ATSR and VIRS satellite data were used to extend the burned area time series back in time through 1997. In our analysis we estimated fuel loads, including organic soil layer and peatland fuels, and the net flux from terrestrial ecosystems as the balance between net primary production (NPP), heterotrophic respiration (Rh), and biomass burning, using time varying inputs of precipitation (PPT), temperature, solar radiation, and satellite-derived fractional absorbed photosynthetically active radiation (fAPAR). For the 1997–2004 period, we found that on average approximately 58 Pg C year−1 was fixed by plants as NPP, and approximately 95% of this was returned back to the atmosphere via Rh. Another 4%, or 2.5 Pg C year−1 was emitted by biomass burning; the remainder consisted of losses from fuel wood collection and subsequent burning. At a global scale, burned area and total fire emissions were largely decoupled from year to year. Total carbon emissions tracked burning in forested areas (including deforestation fires in the tropics), whereas burned area was largely controlled by savanna fires that responded to different environmental and human factors. Biomass burning emissions showed large interannual variability with a range of more than 1 Pg C year−1, with a maximum in 1998 (3.2 Pg C year−1) and a minimum in 2000 (2.0 Pg C year−1).

Drainage of peatlands and deforestation have led to large-scale fires in equatorial Asia, affecting regional air quality and global concentrations of greenhouse gases. Here we used several sources of satellite data with biogeochemical and atmospheric modeling to better understand and constrain fire emissions from Indonesia, Malaysia, and Papua New Guinea during 2000–2006. We found that average fire emissions from this region [128 ± 51 (1σ) Tg carbon (C) year −1 , T = 10 12 ] were comparable to fossil fuel emissions. In Borneo, carbon emissions from fires were highly variable, fluxes during the moderate 2006 El Niño more than 30 times greater than those during the 2000 La Niña (and with a 2000–2006 mean of 74 ± 33 Tg C yr −1 ). Higher rates of forest loss and larger areas of peatland becoming vulnerable to fire in drought years caused a strong nonlinear relation between drought and fire emissions in southern Borneo. Fire emissions from Sumatra showed a positive linear trend, increasing at a rate of 8 Tg C year −2 (approximately doubling during 2000–2006). These results highlight the importance of including deforestation in future climate agreements. They also imply that land manager responses to expected shifts in tropical precipitation may critically determine the strength of climate–carbon cycle feedbacks during the 21st century.

Hansen; Joanna Isobel House; C. Le Quéré; Julia Pongratz; Julia Pongratz; G. R. van der Werf; Navin Ramankutty; Richard A. Houghton; Ruth DeFries;Abstract. The net flux of carbon from land use and land-cover change (LULCC) accounted for 12.5% of anthropogenic carbon emissions from 1990 to 2010. This net flux is the most uncertain term in the global carbon budget, not only because of uncertainties in rates of deforestation and forestation, but also because of uncertainties in the carbon density of the lands actually undergoing change. Furthermore, there are differences in approaches used to determine the flux that introduce variability into estimates in ways that are difficult to evaluate, and not all analyses consider the same types of management activities. Thirteen recent estimates of net carbon emissions from LULCC are summarized here. In addition to deforestation, all analyses considered changes in the area of agricultural lands (croplands and pastures). Some considered, also, forest management (wood harvest, shifting cultivation). None included emissions from the degradation of tropical peatlands. Means and standard deviations across the thirteen model estimates of annual emissions for the 1980s and 1990s, respectively, are 1.14 ± 0.23 and 1.12 ± 0.25 Pg C yr−1 (1 Pg = 1015 g carbon). Four studies also considered the period 2000–2009, and the mean and standard deviations across these four for the three decades are 1.14 ± 0.39, 1.17 ± 0.32, and 1.10 ± 0.11 Pg C yr−1. For the period 1990–2009 the mean global emissions from LULCC are 1.14 ± 0.18 Pg C yr−1. The standard deviations across model means shown here are smaller than previous estimates of uncertainty as they do not account for the errors that result from data uncertainty and from an incomplete understanding of all the processes affecting the net flux of carbon from LULCC. Although these errors have not been systematically evaluated, based on partial analyses available in the literature and expert opinion, they are estimated to be on the order of ± 0.5 Pg C yr−1.

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 sets and methodology to quantify the five major components of the global carbon budget and their uncertainties. Fossil CO2 emissions (EFOS) are based on energy statistics and cement production data, while emissions from land-use change (ELUC), mainly deforestation, are based on land use and land-use change data and bookkeeping models. Atmospheric CO2 concentration is measured directly and its growth rate (GATM) is computed from the annual changes in concentration. The ocean CO2 sink (SOCEAN) and terrestrial CO2 sink (SLAND) are estimated with global process models constrained by observations. The resulting carbon budget imbalance (BIM), the difference between the estimated total emissions and the estimated changes in the atmosphere, ocean, and terrestrial biosphere, is a measure of imperfect data and understanding of the contemporary carbon cycle. All uncertainties are reported as ±1σ. For the last decade available (2010–2019), EFOS was 9.6 ± 0.5 GtC yr−1 excluding the cement carbonation sink (9.4 ± 0.5 GtC yr−1 when the cement carbonation sink is included), and ELUC was 1.6 ± 0.7 GtC yr−1. For the same decade, GATM was 5.1 ± 0.02 GtC yr−1 (2.4 ± 0.01 ppm yr−1), SOCEAN 2.5 ± 0.6 GtC yr−1, and SLAND 3.4 ± 0.9 GtC yr−1, with a budget imbalance BIM of −0.1 GtC yr−1 indicating a near balance between estimated sources and sinks over the last decade. For the year 2019 alone, the growth in EFOS was only about 0.1 % with fossil emissions increasing to 9.9 ± 0.5 GtC yr−1 excluding the cement carbonation sink (9.7 ± 0.5 GtC yr−1 when cement carbonation sink is included), and ELUC was 1.8 ± 0.7 GtC yr−1, for total anthropogenic CO2 emissions of 11.5 ± 0.9 GtC yr−1 (42.2 ± 3.3 GtCO2). Also for 2019, GATM was 5.4 ± 0.2 GtC yr−1 (2.5 ± 0.1 ppm yr−1), SOCEAN was 2.6 ± 0.6 GtC yr−1, and SLAND was 3.1 ± 1.2 GtC yr−1, with a BIM of 0.3 GtC. The global atmospheric CO2 concentration reached 409.85 ± 0.1 ppm averaged over 2019. Preliminary data for 2020, accounting for the COVID-19-induced changes in emissions, suggest a decrease in EFOS relative to 2019 of about −7 % (median estimate) based on individual estimates from four studies of −6 %, −7 %, −7 % (−3 % to −11 %), and −13 %. Overall, the mean and trend in the components of the global carbon budget are consistently estimated over the period 1959–2019, but discrepancies of up to 1 GtC yr−1 persist for the representation of semi-decadal variability in CO2 fluxes. Comparison of estimates from diverse approaches and observations shows (1) no consensus in the mean and trend in land-use change emissions over the last decade, (2) a persistent low agreement between the different methods on the magnitude of the land CO2 flux in the northern extra-tropics, and (3) an apparent discrepancy between the different methods for the ocean sink outside the tropics, particularly in the Southern Ocean. This living data update documents changes in the methods and data sets used in this new global carbon budget and the progress in understanding of the global carbon cycle compared with previous publications of this data set (Friedlingstein et al., 2019; Le Quéré et al., 2018b, a, 2016, 2015b, a, 2014, 2013). The data presented in this work are available at https://doi.org/10.18160/gcp-2020 (Friedlingstein et al., 2020).

Rogers;Roughly 3% of the Earth's land surface burns annually, representing a critical exchange of energy and matter between the land and atmosphere via combustion. Fires range from slow smouldering peat fires, to low-intensity surface fires, to intense crown fires, depending on vegetation structure, fuel moisture, prevailing climate, and weather conditions. While the links between biogeochemistry, climate and fire are widely studied within Earth system science, these relationships are also mediated by fuels-namely plants and their litter-that are the product of evolutionary and ecological processes. Fire is a powerful selective force and, over their evolutionary history, plants have evolved traits that both tolerate and promote fire numerous times and across diverse clades. Here we outline a conceptual framework of how plant traits determine the flammability of ecosystems and interact with climate and weather to influence fire regimes. We explore how these evolutionary and ecological processes scale to impact biogeochemical and Earth system processes. Finally, we outline several research challenges that, when resolved, will improve our understanding of the role of plant evolution in mediating the fire feedbacks driving Earth system processes. Understanding current patterns of fire and vegetation, as well as patterns of fire over geological time, requires research that incorporates evolutionary biology, ecology, biogeography, and the biogeosciences.

H; Stocks, B. J; van der Werf, G. R; Randerson, J. T;Satellite fire products have the potential to construct inter‐annual time series of fire activity, but estimating area burned requires considering biases introduced by orbiting geometry, fire behavior, and the presence of clouds and smoke. Here we evaluated the performance of fire counts from the Advanced Thermal Scanning Radiometer (ATSR) for the boreal forest region using area burned information from other sources. We found ATSR detection rate varied between regions and different years, being higher during large fire years than during small fire years. The results show ATSR fire counts do not represent an unbiased sample of fire activity, and independent validation may be required prior to using this data set in studies of global emissions from biomass burning.
