#Geoengineering is not the way to address #climatechange in the polar regions!

Our review of the 5 most prominent polar geoengineering ideas concludes that none are viable. Instead, they are environmentally dangerous and have major governance & ethics issues

🆕 Four key parts of the Earth’s climate system are destabilising. Researchers analysed the interconnections of #Greenland ice sheet, #AMOC, #Amazon rainforest and the South American monsoon system. All four show signs of diminished resilience: www.pik-potsdam.de/en/news/late... @climtip.bsky.social

Sep 2025 update. If globally adopted:

Critically Insufficient - policies are consistent with 4°C or more of heating
Highly Insufficient - On track for about 3–4°C
Insufficient - policies would lead to warming of 2–3°C
Almost Insufficient - policies would keep warming within the 2°C limit

Trump spreading fossil fuel propaganda lies at the UN - what an embarrassing president for the US.

"results were mixed. The LLM... effectively summed up commentary content... for a lay audience. However, it tended to sacrifice accuracy for simplicity... extensive editing for hyperbole was needed... It also struggled to highlight more than one result from multifaceted studies."

In 2024, a team of science writers at AAAS ran a long-term experiment to see if ChatGPT could cut it writing news items about scientific research. Here's what they learned. Worth a look. 🧪 #scicomm

Plans to refreeze the Arctic have a snowball's chance in hell of succeeding. Authoritative analyses that conclude "needs further research" isn't likely to change that.

The UK Government has clarified that it is opposed to polar #geoengineering

"This week a group of 42 polar scientists published analysis which found that proposed geoengineering techniques were not feasible and could even be “environmentally dangerous”.

Counterpoint: The proposals are so preposterous and impossible that they show we must stop burning fossil fuels or everything's going to be terrible. There's no other way.

Polar #geoengineering dismissed as “unimaginably expensive” and “dangerous”

Giant underwater curtains and artificial ice thickening diverts attention from cutting fossil fuel burning, climate scientists argue - but proponents disagree

"Polar geoengineering proposals raise false hopes for averting some disastrous consequences of climate change without rapidly cutting,,emissions"

"They risk encouraging complacency about the urgency of achieving net zero or may be used by powerful actors as an excuse to justify continued emissions"
High-tech plans to save polar ice will fail, new research finds
The plans could also unintentionally harm fragile polar ecosystems.

With emissions still rising 📈 and the catastrophic consequences 🔥 becoming ever clearer, geoengineering is getting ever more tempting 🧪

But a review has concluded that the main methods proposed to save polar ice 🧊 are not doable or won't work

Geoengineering is not going to save the poles from climate change
A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both

Our paper is out, providing alternative viewpoints to some polar geoengineering ideas covered in the media recently. Lots still to talk about but let's focus on decarbonising instead of drilling Antarctica for now? 🇦🇶
Thanks @newscientist.com @mjflepage.bsky.social for covering this important issue!
