View article: The global hydrogen budget
The global hydrogen budget Open
Hydrogen (H2) will play a part in decarbonizing the global energy system1. However, hydrogen interacts with methane, ozone, and stratospheric water vapour, leading to an indirect 100-year global warming potential of 11 ± 4 (refs. 2-5). Thi…

Diagnosing linearity along the carbon cascade in terrestrial biosphere models Open
Elevated carbon dioxide (eCO 2 ) fertilises photosynthesis, driving an increase in terrestrial gross primary production (GPP). However, it is unclear how effectively increased GPP propagates along the “carbon (C) cascade” to increase net p…

Importance of plant functional type, dynamic vegetation, and fire interactions for process-based modeling of gross carbon uptake across the drylands of western North America Open
Drylands cover ~41 % of the Earth’s land surface and contribute more than one third of the global net primary productivity. Several studies have demonstrated that drylands play a crucial role in global carbon cycle interannual variability.…

An improved approach to estimate the natural land carbon sink Open
The natural land carbon sink (SLAND) absorbs roughly 25-30% of anthropogenic CO2 emissions, playing a critical role in offsetting climate warming. In the Global Carbon Budget (GCB), SLAND is estimated using simulations that isolate the env…

JMIP 2 Part 1: Technology uncertainty and robustness in Japan’s net-zero pathways Open
Japan’s commitment to reach net-zero 2050 hinges on innovation in emerging, uncertain technologies. Yet, no study has systematically examined uncertainties in technology development for Japan’s net-zero goal in a multi-model framework. Her…

Trends and Drivers of Terrestrial Sources and Sinks of Carbon Dioxide: An Overview of the TRENDY Project Open
The terrestrial biosphere plays a major role in the global carbon cycle, and there is a recognized need for regularly updated estimates of land‐atmosphere exchange at regional and global scales. An international ensemble of Dynamic Global …

Residual emissions and carbon removal towards Japan’s net-zero goal: a multi-model analysis Open
We study Japan’s net-zero emissions target by 2050 in a multi-model framework, focusing on residual emissions and carbon dioxide removal (CDR). Four energy-economic and integrated assessment models show similar but stronger strategies for …

Soil respiration–driven CO <sub>2</sub> pulses dominate Australia’s flux variability Open
The Australian continent contributes substantially to the year-to-year variability of the global terrestrial carbon dioxide (CO 2 ) sink. However, the scarcity of in situ observations in remote areas prevents the deciphering of processes t…

Harmonising the land-use flux estimates of global models and national inventories for 2000–2020 Open
As the focus of climate policy shifts from pledges to implementation, there is a growing need to track progress on climate change mitigation at the country level, particularly for the land-use sector. Despite new tools and models providing…

Amazon forests a net carbon source during drought and under high rates of human-disturbance Open
The Amazon is the largest continuous tropical forest in the world and plays a key role in the global carbon cycle. Human-induced disturbances and climate change have impacted the Amazon carbon balance. Here we conduct a comprehensive analy…
