I often see confusion about how we measure NEE by eddy-covariance, even among scientists.
@AmeriFlux calls turbulent flux of CO2 "FC" and label it "turbulent flux, no storage correction". The "storage correction" is called "SC". https://t.co/DDf1sfb1Bm

We figured out how much water is in all of Earth’s plants and how long it takes water to flow through them.

Answer: 786 km3 and 5-18 days.

I have a new analysis over at The Climate Brink exploring how rates of warming have changed over the past century.

Post-1970, GHGs (CO2, CH4, etc.) would have led to just under 0.2C per decade, but falling aerosols (SO2) have increased that rate to 0.25C.

We have just published the new @gcarbonproject Global Carbon Budget, 2024.

It contains a mix of bad news and some less bad news. The latter signals some progress, albeit slow, towards decarbonizing the global economy.

The exponential growth of solar + wind energy continues to be astonishing

@MiguelDMahecha @EnvDataScience I think we should move to a more open system. 2-5 reviewers doesn't mean "scientific consensus" yet it is published. We should openly "publish" online and let scientific feedback from the community openly argue, let the work evolve and lead to an actual consensus. Colaborate...

Today, I’m excited to share with you all the fruit of our effort at @OpenAI to create AI models capable of truly general reasoning: OpenAI's new o1 model series! (aka 🍓) Let me explain 🧵 1/

Thrilled to see this paper published - an international collaborative work involving modellers and experimentalists. We assessed the C-P interactions in models and their responses to elevated CO2 @westsyduhie @westernsydneyu @ZJU_China

[Prof. Belinda Medlyn @b_medlyn]

Our new paper lines up P-enabled vegetation models against results from #EucFACE experiment and asks: how did they do? Congrats @jiangmingkai for a huge effort co-ordinating modelling and experimental communities! @westernsydneyu @westsyduhie

Excited to see the hard-won #EucFACE Phosphorus budget published in @springernature today. Many thanks to lead authors @jiangmingkai and Kristine Crous!

Heading to Vienna #BiDS23 @EO_OPEN_SCIENCE to show how we use @JuliaLanguage and @MakiePlots to analyse large geospatial data, I will be doing some data cubes @DeepCube_H2020 showing @ClaireRobin01 research @Ellis_Unit_Jena. If you are around and want to talk, say Hi!

@dr_wusun the framework of publishing is very slow and random - I've had amazing and terrible experiences with the review process.
Publishing was a great system 50 years ago. Nowadays we have new technologies and I feel like the scientific journal system is lagging behind.
