Impact of the Ukrainian crisis on the global food security
Jean Cyrus de Gourcuff, David Makowski, Philippe Ciais +1
Using global wheat trade data and a network model for shock propagation, we study the impact of the Ukrainian crisis on food security. Depending on the level of reduction in Ukrain…
Carbon loss from forest degradation exceeds that from deforestation in the Brazilian Amazon
Yuanwei Qin, Xiangming Xiao, Jean-Pierre Wigneron +11
Spatial-temporal dynamics of aboveground biomass (AGB) and forest area affect the carbon cycle, climate, and biodiversity in the Brazilian Amazon. Here we investigate inter-annual…
Global fossil carbon emissions rebound near pre-COVID-19 levels
RB Jackson, P Friedlingstein, C Le Quere +8
Global fossil CO2 emissions in 2020 decreased 5.4%, from 36.7 Gt CO2 in 2019 to 34.8 Gt CO2 in 2020, an unprecedented decline of ~1.9 Gt CO2. We project that global fossil CO2 emis…
Global Gridded Daily CO Emissions
Xinyu Dou, Yilong Wang, Philippe Ciais +15
Precise and high-resolution carbon dioxide (CO) emission data is of great importance of achieving the carbon neutrality around the world. Here we present for the first time the…
Unprecedented decarbonization of China's power system in the post-COVID era
Biqing Zhu, Rui Guo, Zhu Deng +7
In October of 2020, China announced that it aims to start reducing its carbon dioxide (CO2) emissions before 2030 and achieve carbon neutrality before 20601. The surprise announcem…
Global Daily CO emissions for the year 2020
Zhu Liu, Zhu Deng, Philippe Ciais +25
The diurnal cycle CO emissions from fossil fuel combustion and cement production reflect seasonality, weather conditions, working days, and more recently the impact of the COVI…
De-carbonization of global energy use during the COVID-19 pandemic
Zhu Liu, Biqing Zhu, Philippe Ciais +15
The COVID-19 pandemic has disrupted human activities, leading to unprecedented decreases in both global energy demand and GHG emissions. Yet a little known that there is also a low…
Transportation CO emissions stayed high despite recurrent COVID outbreaks
Yilong Wang, Zhu Deng, Philippe Ciais +5
After steep drops and then rebounds in transportation-related CO emissions over the first half of 2020, a second wave of COVID-19 this fall has caused further -- but less subst…
Regional Impacts of COVID-19 on Carbon Dioxide Detected Worldwide from Space
Brad Weir, David Crisp, Christopher W O'Dell +11
Activity reductions in early 2020 due to the Coronavirus Disease 2019 pandemic led to unprecedented decreases in carbon dioxide (CO2) emissions. Despite their record size, the resu…
Satellite-based estimates of decline and rebound in China's CO emissions during COVID-19 pandemic
Bo Zheng, Guannan Geng, Philippe Ciais +13
Changes in CO emissions during the COVID-19 pandemic have been estimated from indicators on activities like transportation and electricity generation. Here, we instead use sate…
Carbon Monitor: a near-real-time daily dataset of global CO2 emission from fossil fuel and cement production
Zhu Liu, Philippe Ciais, Zhu Deng +15
We constructed a near-real-time daily CO2 emission dataset, namely the Carbon Monitor, to monitor the variations of CO2 emissions from fossil fuel combustion and cement production…
Cost-effective implementation of the Paris Agreement using flexible greenhouse gas metrics
Katsumasa Tanaka, Olivier Boucher, Philippe Ciais +2
Greenhouse gas (GHG) metrics, that is, conversion factors to evaluate the emissions of non-CO2 climate forcers on a common scale with CO2, serve crucial functions upon the implemen…
