BDP @dankammen.bsky.social recently published a blog post with the @ox.ac.uk that argues for the centrality of science, research, and innovation in the public sphere in order to uphold climate and social justice.

The politics of renewables are getting stranger. ‘Sun Day’ celebrates them anyway. The national day of action on September 21 arrives at a time when clean energy is becoming more polarized.

Nice to see Grist reporter @kateyoder laying out the 'flipped economics' of clean energy -- now cheaper, faster and more jobs than fossil energy -- in advance of @climateweeknyc.bsky.social @theclimategroup.bsky.social

This fantastic science & engagement by @setiinstitute.bsky.social is such a double win: important work (see, for example the @unistellar.bsky.social @nasaexoplanets.extwitter.link @nasawebb.extwitter.link work with SETI) and a way for the public to see science in action.

As usual, @rbreich.bsky.social is spot on the greed at the top.

But is is only half the story. The depressingly accurate work by @gabrielzucman.bsky.social and Emmanuel Saez highlights how the ultra-rich now pay lower taxes than the poor.

In an excellent question from @chris8048.bsky.social on recent nuclear plant costs in France my co-author @shangwei-liu.bsky.social notes and corrects the record:

That is a key: the industry-regulatory bond is tight in @chinadigitaltimes.net - short-term
benefit possible long-term concern?

The related question is over cost dynamics: these are overnight costs and those of operation of young plants very different from later in life and of course at end of life

China reins in the spiralling construction costs of nuclear power — what can other countries learn? Strengthening regulations and domestic supply chains could be key to making nuclear power more economically viable.
