Emissions from Fossil Fuels Continue to Rise, 2023.

The finding is part of an annual checkup on Earth’s carbon cycle called the Global Carbon Budget.

See NASA's take on it.

New community effort out for discussion: we apply the Adaptive Emission Reduction Approach to an ensemble of Earth System Models. All ESMs stabilise at the same GWL, unveiling the emission pathways and remaining budgets compatible with stabilising global warming at 1.5 and 2ºC.

1/5 Climate change + continued emissions = increasing degrees of difficult and increasing consequential harm.

The correct headline is “Wow! 85% (or more) of Americans believe in climate change! That’s about the same number that know the Earth is round”

La transition du système électrique a bien lieu en UE. Les émissions de CO2 de ce secteur ont connu un pic en 2007 à 1218 MtCO2, elles sont depuis passées à 653 MtCO2, soit une réduction de 46 % en 16 ans !

Carbon Monitor global CO₂ emissions updates for full year 2023: Global CO2 increased by +0.1% in 2023, another year with historical high number.

Nice piece on overshoot scenarios. In a nutshell it won’t be as easy as it sounds 😉

📢We are searching for a new Team Lead of the Land Modelling Team ECMWF. This very important position provides access to a great diverse team, fantastic science challenges (e.g. around ML) and direct impact on the quality of numerical weather prediction.

A favourite justification for continued oil exploration is that it is needed for non-energy use (plastics, etc).

Fine, this is what 1.5°C scenarios assume. Nearly all oil in 2050 is for non-energy.

This is why oil goes down 80% & not 100%.

(figure based on the IEA)

“Al Jaber has managed what no other Cop presidency has ever done: to bring Saudi Arabia to the table to agree that a transition away from fossil fuels must be a global priority.”

Trop fort !!!

Huge respect 🙏

Essentially, given the very limited remaining carbon budget, OECD countries should phase out coal by 2030, oil and gas by 2040. Non-OECD countries would get 10 more years.
