I'm looking to find :
the R (dataviz) community,
the ocean acidification and invert 🐙 communities,
and more broadly people who care about climate change !

The other certainty about overshoot is that even if we eventually get back to 1.5°C, a lot more people will suffer because we didn’t reduce emissions earlier and more rapidly.
Now that we are likely to cross 1.5°C, there is increasing discussion on "overshoot".
There is a lot of uncertainties on overshoot, but there is one thing that we are 100% sure about:
GHG emissions need to go down >90% in decades for overshoot to be a reality.

Biotic marine CO₂ removal relies on export of organic carbon from the surface ocean to the deep sea, where CO₂ will be kept out of the atmosphere even if the organic matter is remineralized.
Deep-sea mining will bring this carbon to the ocean surface and release CO₂ to the atmosphere. Not awesome.

Deep-sea mining risks harming one of the last pristine ecosystems--but if it goes ahead under Trump, it could at least be done more sustainably by smelting the metal nodules with hydrogen plasma www.newscientist.com/article/2505...
Have we found a greener way to do deep-sea mining?
There are widespread concerns that deep-sea mining for metals will damage fragile ecosystems. But if mining ever goes ahead, hydrogen plasma could shrink the carbon footprint of smelting the metal ore...

Yes. I read a an essay about this by a political scientist 15 years ago and it’s lived rent free in my brain ever since.
In a nutshell, he said, the more unstable and out of control the world seems, the more people are willing to cede power to authoritarian leaders.

Looking at the “bright” side, 35 economies are decarbonizing: reducing their fossil CO₂ emissions while having a growing economy.
Together they account for 27% of global fossil CO₂ emissions.

Looking at the major economies, Fossil CO₂ emission for
China: +0.4%. That’s much lower than the average growth of the past decade (+2.5%/yr). Progress here, largely due to the rapid development of renewable.

EU: +0.4%. Also opposite to the declining trend of the past 10 years (-2.5%/yr). Cold winter led to increased heating demand and weather-related low hydropower and wind generation led to an increase in electricity generation from natural gas.

It's astounding how much CO₂ we put into the atmosphere each year by burning fossil fuels.
For comparison, we all agree that plastic pollution is bad, but the mass of ALL THE PLASTIC humanity has ever produced is only 25% of the CO₂ we emitted into the atmosphere in 2025.

As @glenpeters.bsky.social says, we're way off target for any 1.5°C scenario.
To see how far off, each of the red/green bars represents the decrease in CO₂ emissions during COVID. Even if we achieved that from now until the end of 2030, we would still miss our 1.5°C target by a significant margin.
