BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency.

Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

1/ I'm constantly amazed at the naivety of so much of conservation science (& other mission-driven disciplines)

As if all we have to do is generate the evidence and society's leaders will use it to do what's needed

As if there's no-one trying to make sure that doesn't happen

arkrewilding.nl/nieuws/2025/... Het werk van ARK op de Noordzee heeft alleen zin als er voldoende rust en ruimte is. Daarom eist ARK, met St Doggerland, dat de overheid zich aan haar eigen regels gaat houden: het Nederlandse deel van de Doggersbank moet op slot voor sleepnetvisserij.

Experimental evidence of the role of nitrogen for eutrophication in shallow lakes: a long-term climate effect mesocosm study

Experimental evidence of the role of nitrogen for eutrophication in shallow lakes: A long-term climate effect mesocosm study
The effectiveness of controlling nitrogen (N) loading (in addition to phosphorus [P]) to manage the eutrophication of aquatic ecosystems has been debated despite the role of N in producing algal biomass and toxins. Long-term, controlled tests of the efficacy of N loading reductions are largely missing from the scientific record, perhaps due to the historical focus on P control. To address this knowledge gap, we examined the results from a unique, long-term study conducted in 24 flow-through (2.5-month retention time) lake ecosystem-scale mesocosms in Denmark, operating since 2003 at two contrasting nutrient loading levels crossed with three temperature scenarios (ambient, IPCC (Intergovernmental Panel on Climate Change) A2 scenario, and A2+50%).

De referentie naar het stikstof kaartje bedoelden de schrijvers denk ik niet als 'up to date info'. Ze gebruikten het als illustratie van hoe duidelijke ruimtelijke keuzen en afwegingen 'besmet' zijn verklaard in het publiek debat, ondergesneeuwd onder zaken als plattelandsidentiteit

btw you can check the website WikiShootMe for nearby landmarks that need freely-licensed photos, visit them, and then snap pics for Wikipedia/Wikimedia Commons! it's so fun and the list of photoless destinations is endless. I chose this movie theater as an example bc it's where I first watched Cars

Many light-demanding European woody plants are thorny or have prickly leaves, making them common in landscapes inhabited by large herbivores (livestock). Many of these species are dispersed by frugivorous birds associated with open habitats
