Trump order gives political appointees vast powers over research grants Researchers are alarmed that the move might upend a long-standing tradition of peer-review for grants.

Trump's new executive order "looks like an explicit attempt to destroy peer review for federal science grants,โ€ a physicist in Texas tells @dangaristo.bsky.social. ๐Ÿงช

Contrasting biological production trends over land and ocean - Nature Climate Change The authors jointly assess the changes in land and ocean net primary production from 2003 to 2021.

๐ŸŒ Green gains, blue losses

From 2003โ€“2021, plants on land grew more, but ocean productivity declined, likely due to climate warming.

Land is boosting Earthโ€™s carbon uptake, but oceans are showing signs of stress.

Analysis: The US government has declared war on the very idea of climate change | CNN Politics Americans are used to whiplash in their climate policy. The US has been in and out and in and out again of the key Paris climate agreement over the past four presidencies.

โ€œIn his second administration, President Donald Trump is not just approaching climate science with skepticism. Instead, his administration is moving to destroy the methods by which his or any future administration can respond to climate change.โ€œ

The suspensions landed perhaps most heavily in math. NSF suspended a $25 million grant for the Institute for Pure and Applied Mathematics (IPAM), an international center at UCLA that hosts about 2000 visiting researchers every year for workshops and other programs. One of its stars, Terence Tao, a Fields Medal winner frequently named as one of the greatest living mathematicians, also had his only NSF grant suspended. The $750,000 award was in its first year and supported Taoโ€™s own research and a handful of graduate students in developing tools to tell whether a set of numbers is structured or random. Tao says he now cannot offer research assistant opportunities during the academic year, and he calls the cuts to IPAM โ€œquite disastrous.โ€

How do tropical #trees deal with droughts? The answer is published today in @science.org

Our pantropical #treering analysis revealed 2.5% growth reduction during #drought years. Yet, growth declined by >10% in 1/4 of 500 study sites, and in hotter & drier regions.

This looks really intriguing Tom! One quibble though - the framing of explanations as being dichotomous as either Newtonian or Darwinian is not correct. Galzier set them up as being opposing, but that is a very diminished view of the literature. They are not mutually exclusive

If we can't think for ourselves, if we're unwilling to question authority, then we're just putty in the hands of those in power. But if the citizens are educated and form their own opinions, then those in power work for us.
