[GWSG] Antarctic CH4; power economy; paying attention; indigenous thinking; right diet

[Tilley, Al]

1. A Spanish expedition has detected massive methane emissions from the seabed in the Antarctic, perhaps from destabilized methane hydrates. While the extent of the threat is not yet clear, this is worth keeping an eye on. https://english.elpais.com/climate/2025-02-12/massive-methane-leaks-detected-in-antarctica-posing-potential-risks-for-global-warming.html
2. A study of power production in 149 countries for the next 25 years concludes that money spent on carbon capture from fossil fuels is counterproductive in terms of energy costs, energy requirements, air pollution, pipelines, and total social costs. It will always be more productive to put the money directly into developing renewables. Stanford’s Mark Jacobson is the lead author. https://techxplore.com/news/2025-02-carbon-capture-renewables.html?utm_source=nwletter&utm_medium=email&utm_campaign=weekly-nwletter
3. Mark Jacobson in “We Need to Keep Our Eye on the Ball to Save the Planet” warns of the ways we are being distracted from completing the energy transition. Air pollution, global warming, and energy security are all at stake. Many of the measures given most attention—direct air carbon capture, new nuclear plants, blue hydrogen, and bioenergy, for example—delay necessary actions and thus serve the fossil fuel industry. To keep heating from going beyond 1.5C we need to eliminate 80% of our greenhouse gas emissions by 2030 and the test by 2035. We have the technology to do that. https://cleantechnica.com/2025/02/19/we-need-to-keep-our-eye-on-the-ball-to-save-the-planet/
4. Indigenous futures thinking can help us imagine being at home on the planet.  The approach is summarized under four descriptors: adaptation oriented, participatory, culturally grounded, and indigenizing. In the midst of reading about the blundering lurches of a Trump administration headed for a world which few would want to (or even be able to) inhabit, the article struck me as liberating. https://phys.org/news/2025-02-indigenous-futures-approaches-world.html
5.   Following the Planetary Health Diet puts us already partly inside a future fit to be desired. https://eatforum.org/eat-lancet-commission/eat-lancet-commission-summary-report/  It is the strongest climate action you can take, unless you are in a position to guide public policy. https://drawdown.org/insights/the-powerful-role-of-household-actions-in-solving-climate-change
