For those interested in N2O, the Global Carbon Project is running a session at the AGU meeting this December in San Francisco B052 - Global Nitrous Oxide Budget: Sources, Drivers, Uncertainties, and Mitigation Pathways agu.confex.com/agu/agu26/pr... Deadline for abstract submission: August 5

1/3 Using the global wetland model ensemble of the Global Carbon Project-Global Methane Budget, constrained by 163 site-year measurements, Zhen Zhang, @benpoulter.bsky.social & colleagues show that for every 1 degree C increase in global temperature, CH4 emissions increase by 24Tg per year

1/n We just published a global assessment of GHG emissions from global rice cultivation. Led by Jingting Zhang & Hanqin Tian, this is part of the Global Carbon Project's efforts to constrain the Global Methane Budget & provide relevant data for GHG mitigation. theconversation.com/rice-feeds-b...

Rice feeds billions of people – but its role in fueling climate change is growing

There are ways to reduce emissions without sacrificing yield. A new study shows how, and looks at a technique billed as ‘climate-friendly’ that makes emissions worse.

1/2 Next week, I’ll join experts from across the research, industry and policy communities at FRAME – the Forum for Reducing Australia’s Methane Emissions. Over two days, we’ll examine methane measurement and abatement, share emerging knowledge, and support stronger cross-sector understanding.

Join us for the 12th International Carbon Dioxide Conference, the leading international conference on the global carbon cycle and its critical role in the Earth system. 21-25 June 2027, Exeter, UK. Register your interest: icdc12.org #ICDC12 #GlobalCarbonBudget #CarbonCycle

What happens to the climate system when global CO2 emissions reach zero? We all know that the temperature stops rising (stays approximately constant), but there are a few implications... rdcu.be/e73i4 1/

1/1 The GCP-Global Carbon Budget 2025 has just been published in its final form. It is the same data we released at the last COP in Nov 2025, but given the many improvements this budget introduced compared to previous editions, it underwent a longer and more detailed peer review process.

The Global Carbon Project has just published the most comprehensive Global Hydrogen Budget to date. H2, although not a GHG, has an indirect Global Warming Potential 37 times more potent than CO2. Carbon Brief: www.carbonbrief.org/hydrogen-emi... Research paper: www.nature.com/articles/s41...

Hydrogen emissions are ‘supercharging’ the warming impact of methane - Carbon Brief

The warming impact of hydrogen has been “overlooked” in projections of climate change, authors of the latest “global hydrogen budget” say.

Last couple of days, if you are interested. Even if you don't want or qualify for funding, you might be interested in participating in this new activity with your in-kind support.

1/2 For Biospheric Modelers There is a new activity led by @benpoulter.bsky.social at SPARK, supported by the GCP, called Warming Induced Emissions-Model Intercomparison (WIE-MIP). There is a call for involvement and a funding opportunity with a deadline at the end of November.

📢Global Carbon Budget 2025📢 Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength. The key findings are covered in two reports this year: * ESSDD (preprint): essd.copernicus.org/preprints/es... * Nature: www.nature.com/articles/s41... 1/

It is worth a reminder that each year we revised the carbon budget in all years, not just the last year www.carbonbrief.org/analysis-fos... This year we had a rather big adjustment in land-use change emissions, including the change in carbon density due to CO2 fertilisation, etc. rdcu.be/ePDDS

The 2025 update of the Global Carbon Budget is out.​​ While fossil CO2 emissions rise again and carbon sinks are weakened by climate change, deforestation emissions are down and many countries decarbonise their energy. No global emissions peak yet though. theconversation.com/the-worlds-c...

The world’s carbon emissions continue to rise. But 35 countries show progress in cutting carbon

In 2025 the world has fallen short, again, of peaking and reducing its fossil fuel use. But there are many countries on a path to greener energy.

1) Fossil fuel Still no peak. Emissions are projected to increase by 1.1% in 2025, reaching 38.1 GtCO2. An all time high.

1/2 We just published the Global Carbon Budget 2025, with a mix of bad news (CO2 emissions continue to grow) and encouraging news (35 countries saw emissions decline over the past decade while growing their economies). Read the highlights in a short article: theconversation.com/the-worlds-c...

The new 2025 Global Carbon Budget finds that fossil fuel emissions will reach a new high in 2025. Total CO2 emissions (including land use) remain flat at 2024 levels. While the land sink is up from 2024, carbon sinks are weakening: www.carbonbrief.org/...

There is increasing talk about overshoot of 1.5°C, particularly that *now* we can only achieve 1.5°C by first overshooting 1.5°C. Well, sorry to tell you, 1.5°C have always been overshoot scenarios. Here from the original 'SSP' 1.5°C scenarios published in 2018. [Overshoot is a scenario design]

As part of the GCP-Regional Carbon Cycle Assessment and Processes-2, we recently published the Australasia's CH4 and N2O Budgets. The carbon budget was published in 2023, both papers, led by Yohanna Villalobos and a great team of collaborators. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
