New #NDCs ahead of #COP30 point to global emissions decreasing 10% by 2035, far short of the 60% needed to keep global warming below 1.5C.

UN Sees World’s Emissions Falling 10% by 2035, Far Short of 60% Goal
The pace of emissions reductions is “still not nearly fast enough,” according to UNFCCC’s Stiel.

Insightful @washingtonpost.com article about US #ElectricityPrices, summarising @lbnlengineering.lbl.gov study on how more electricity demand can actually lower prices: www.washingtonpost.com/climate-envi...
There’s a reason electricity prices are rising. And it’s not data centers.
It’s not data centers or AI, it’s something else.

With all of Trump's recent funding cuts for green hydrogen, the always daunting task of competing against China's cleantech juggernaut is looking more challenging for the US industry.

Trump’s Hydrogen Cuts Put the US Further Behind China on Key Green Tech
China already produces 60% of the world’s electrolyzers, and it continues to provide policy support to bring down the costs of the clean fuel.

20 straight days with 30 °C in Finland! Truly unprecedented heatwave still in full swing with maximum today about 32-33 degrees.
Even the Arctic regions (e.g. Sodankylä Tähtelä) have seen three weeks above 25 °C, and may rival tomorrow their August heat records.

This is unbelievable.
The high temperature at one of Finland’s northernmost weather stations, in the municipality of Sodankylä (Lapland region) within the Arctic Circle at latitude 67.3°N, reached at least 25°C for 26 days in a row.
Records date back to 1908.

IEA's new report on #AI & #Energy gives a sense of how much the growing use of data centres will affect global emissions: In 2024, #DataCentres worldwide accounted for 0.5% of energy-related CO2 (180 Mt). In 2035, data centres' share rises to 1%-1.5% (~500 Mt) in IEA projections. #energysky 1/
