Astonishing to see the so-called "expert review" function of Grammarly exploiting my name for profit without any permission.

Thank you @mathildesaliou.com for pointing this out :

I understand that the function has been shut down after massive backlash and lawsuits.

Why does this matter? El Niño adds to climate change, shifting temperature + rainfall patterns around the world. That in turn affects wildfire, flood and drought risk; food, water, and health; and can even double the risk of civil conflict in tropical regions (Source: www.nature.com/articles/nat...)

The gas-powered data center craze has come to Europe.

Yesterday, a 110MW off-grid AI data center outside of Dublin was switched on - and it's powered entirely by fossil fuels.

Developers went with natural gas engines (specifically RICE) to bypass the grid connection queue. They claim the engines "could" be switched to HVO, and that the project will attempt to connect to the grid "when possible".

What does this mean for Ireland's climate goals? According to my estimates, this single project will increase the entire country's annual GHG emissions by ~1%.

Assumptions:
- The project seems to be using Rolls Royce (mtu) 4000 Series RICE which have an electrical efficiency of 44% https://lnkd.in/eRX4PRuf
- Modifying the NREL life cycle gas emissions factor with this efficiency yields 656.75 gCO2e/kWh https://lnkd.in/gfgs2X6P
- Assuming a 90% capacity factor because AI hyperscale data centers run near 24/7 to recoup massive GPU costs
- Ireland’s 2024 GHG emissions = 53.8 million tCO2e https://lnkd.in/ejjRgRpE

I've updated the Climate Dashboard to use the new 11-model ENSO multi-model mean to help predict 2026 temperatures.

It caused the 2026 estimate to jump from 1.45C to 1.51C, reflecting the much higher likelihood of a strong El Nino developing: dashboard.theclimate...

Unready for war, AI may already be causing deadly mistakes Gary Marcus discusses if the strike on a school in Iran stems from the use of artificial intelligence in the war.

On the first day of the attacks on Iran, a school in Iran was bombed, killing more than 175. Nobody knows for sure what happened, and nobody wants to take responsibility.

Gary Marcus @garymarcus.bsky.social thinks there's a "good chance" that the incident stems from the use of AI.

At court in The Hague for the hearing of our case against the Dutch govt: they are allowing destructive bottom trawling in the Dogger Bank marine protected area - wreaking havoc on the ecosystem.

We're taking action - because Protected must mean Protected.
