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.

In case you missed this report, published by the Integrated Ocean Carbon Research (IOC-R) program, which is co-sponsored by the Global Carbon Project. unesdoc.unesco.org/ark:/48223/p...

Last chance to apply for this 🌊 job

We have a pretty good understanding of the differences between GHG emission estimates, but when it comes to some sectors (e.g., land), estimates seem all over the place! Why is this? @wflamb.bsky.social has you covered... essd.copernicus.org/articles/18/... 1/

A new paper for anyone interested in the role of forest conservation, forestry, and forest products as climate solutions. Led by Didac Pascual and Anders Ahlstrom from Lund University. theconversation.com/swedens-old-...

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...

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.

The atmospheric CO₂ growth rate was off the chart in 2024!

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...

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

Published today in Earth System Science Data: The Global Carbon Budget 2025 essd.copernicus.org/preprints/es...

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...

📢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/

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/...

1/2 To support this year's Global Carbon Budget, 2025, we are publishing The big paper, made possible by the strong commitment of a core group of scientists, with @pfriedling.bsky.social at the lead, working with a network of equally committed contributors from 102 research organizations worldwide

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/...

1/2 I feel privileged to have had the opportunity to make a small contribution to this paper, just published. "Building relationships between First Nations Peoples and Western scientists to increase capacity to understand, respond and adapt to climate change"

New assessment on the biophysical potential of forestation to sequester carbon. As expected, we found just a fraction of what other assessments found, because we considered the obvious no-nos, such as risk to biodiversity, excess water use, and regional warming. theconversation.com/the-climate-...

1/3 A new study, led by Matthias Cuntz and our dearest late Vanessa Haverd, shows beautifully how the increase of the seasonal variation in atmospheric CO2 in the Northern Hemisphere over the past 40 years can only be explained by an increase in the CO2 uptake by plants. doi.org/10.1029/2025...

Interesting new article showing the overwhelming role of tropical forests in past climates. Hard not to wonder about what it means for today’s climate crisis and the changes we see in tropical regions and particularly the Amazon. theconversation.com/around-250-m...

Tree-burning #Drax power station is UK’s largest single source of CO₂ emissions—and a major air polluter. Yet ludicrously, UK Gov pretends its emissions are zero. Reports on its impact on primary forests have been covered up. Ministers are being played. Again. Great article by @dalevince.com

Northern Hemisphere forests now emit more carbon than they absorb. 🌲🔥 Using @esa.int SMOS satellite data, researchers from ESA Climate Change Initiative’s RECCAP-2 project uncovered this shift, driven by droughts, wildfires, and climate disruptions. Learn more: climate.esa.int/en/news-even...

1/3 There is so much discussion about TIPPING POINTS, yet there are so few current large-scale examples that have been demonstrated quantitatively. Xiaojun Li et al show a remarkable shift from accumulating carbon in living biomass in the northern temperate regions to losing carbon since 2016.

Finally got around to reading the article, but couldn't see a link to the actual report it discusses. So here it is.

We are often asked about the impact of plastics on carbon emissions and climate change. There is limited information available, and the article below draws some information from the Plastics & Climate Project. Light reading. www.washingtonpost.com/climate-envi...

1/2 I am delighted to see the first special journal issue dedicated to China's GHG accounting and budgets from an incredibly strong research community there, well-connected, and contributing to the international efforts of the Global Carbon Project.

📣 New Comment on Improving land-use emission estimates under the Paris Agreement in Nature Sustainability www.nature.com/articles/s41... Land carbon removals are key on the path to net-zero. Yet, confusion exists on what “anthropogenic” land-use C fluxes are. #LULUCF #IPCC #ParisAgreement 1/7

The 7 billion tonne gap! Climate science & national emissions reporting use different definitions & methods to estimate anthropogenic land-based carbon removals. This is no small issue, but what can we do about it? www.nature.com/articles/s41... (sorry, shareable open link not yet published). 1/
