So maybe a more concise list: - cut fossil use wherever you can at home & in transit - minimize food waste - eat more plants And don’t try to be perfect. Do what you can & lead by example, but even more, push for system changes that make low-GHG actions more affordable, accessible, desirable.

‘Novice workers who rely heavily on AI to complete unfamiliar tasks may compromise their own skill acquisition… We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without delivering significant efficiency gains on average.’ arxiv.org/pdf/2601.20245
Abstract
Al assistance produces significant productivity gains across professional domains, particularly for novice workers. Yet how this assistance affects the development of skills required to effectively supervise AI remains unclear. Novice workers who rely heavily on AI to complete unfamiliar tasks may compromise their own skill acquisition in the process. We conduct randomized experiments to study how developers gained mastery of a new asynchronous programming library with and without the assistance of Al.
We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without delivering significant efficiency gains on average. Participants who fully delegated coding tasks showed some productivity improvements, but at the cost of learning the library. We identify six distinct AI interaction patterns, three of which involve cognitive engagement and preserve learning outcomes even when participants receive AI assistance. Our findings suggest that Al-enhanced productivity is not a shortcut to competence and AI assistance should be carefully adopted into workflows to preserve skill formation - particularly in safety-critical domains.

The only good thing about all this is that it has brought to my attention that the Greenland flag frickin’ rules. #Erfalasorput
The flag of Greenland. The bottom half is red and the top half white, and offset from the center there is a circular design with the bottom half of the circle white and the top half red. It is meant to symbolize ice caps and the sun setting over the ocean.

Day 2 #artAdventCalendar I made several portraits this year including Sophie Brahe (1559 or 1556 -1643) horticulturalist, astronomer, genealogist, & alchemist 🐡👩🏼‍🔬🧪🔭with the gardens at her brother #astronomer Tycho Brahe’s Uraniborg estate, where she often assisted his research, alchemical tools &
My 11” x 14” linocut portrait of Sophie Brahe, a Renaissance aristocrat in headgear, ruff, dark clothing with medallion on a wide band and a long scarf or other thin fabric draped over her shoulders with her hands folded in front of her and alchemical vessels, printed in dark bronze ink, on a bronze background. In green behind her head is a map of the gardens at Uranienborg, with her head at the centre of the diamond shaped pale green knot garden (geometric planned gardens). This is surrounded by an orchard in darker green with semicircle bump outs on each side of the diamond. The stars of Cassiopeia from De stelle nova are printed in gold on top of everything; there are stars across her chest and ruff and in the garden and the large supernova is above her head

These missions' weakness is that many struggle to articulate how strategies for tackling societal issues will directly translate into urgent, immediate GHG reduction, or how they'll double the effect tomorrow. GHGs have a time value: 1 ton/year displaced today is far better than next year.
