California turns on water to create new wetlands on the shore of the shrinking Salton Sea California officials sent water flowing to create new wetlands along the shores of the shrinking Salton Sea. The project is intended to control dust and provide habitat for birds.

World Peatland Day: Protecting a crucial carbon sink Peatlands are one of the world’s biggest carbon sinks. These naturally waterlogged boggy swamps can hold thousands of years’ worth of compressed, partially decomposed vegetation matter — despite…

Peatlands are one of the world’s biggest carbon sinks. Despite covering just 3-4% of Earth’s land surface, they’re thought to store more carbon per area than the world’s forests combined.

In honor of World Peatland Day on June 2 here's three recent Mongabay stories on this critical ecosystem...

‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

When warnings of Insectageddon were issued a few years ago, there was widespread denial. Less so now. It's devastating. www.theguardian.com/environment/...

Agree with the previous comments. You can try three times, and if you don’t succeed you can always submit it to the general programs. And you can turn it into a paper.

This is a cartogram map of the United States depicting land use by different categories. The map distorts state shapes to represent proportional land usage. Key land use types include cow pasture/range (covering much of the central U.S.), private and federal timberland in the Pacific Northwest, corporate timberland in the Southeast, and urban housing/commercial areas in the Northeast. Other categories include agriculture (livestock feed, wheat exports, ethanol/biodiesel, cotton), protected lands (national parks, federal wilderness, state parks), and infrastructure (railroads, airports, highways). Additional specialized land uses include wildfires, golf courses, Christmas tree farms, and maple syrup production.

I think about this map a lot.

World’s largely unprotected peatlands are ticking ‘carbon bomb’, warns study Bogs and swamps are a colossal carbon store but their continued destruction would blow climate change targets

Draining the world's peatlands for farming and mining is releasing so much CO2 that if it was a country, it would be the 4th biggest polluter in the world after China, the US, + India.

And the associated losses in biodiversity are vast.

How I've been thinking about all of the rapid horrible changes in the United States I'm not telling you how to think or feel, but maybe letting you know where I'm at might be useful.

I've been seen lots of feckless despair and detachedness among scientists in the US at the moment. How we might live up to this critical moment when things seem the worst.

A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu

At least we don't have to read about this on a federal government website:

At 2°C of warming, the area on Earth that is too hot for humans will triple. This is fine. 🔥🧪

I can’t wait for the second round of search terms: climate, sea level, etc. For all you scientists (and you know who you are) who think you won’t be affected because your broader impacts are amazingly still limited to training grad students and chatting to K-12 kids, this won’t stop at one list.
