By TAMMY WEBBER  and  JOSHUA A. BICKEL , Associated Press.  Excerpt: CHRISTIANA, Tenn. (AP) — From a distance, the small solar farm in central Tennessee looks like others that now dot rural America, with row upon row of black panels absorbing the sun’s rays to generate electricity. But beneath these panels is lush pasture instead of gravel, enjoyed by a small herd of cattle that spends its days munching grass and resting in the shade. Silicon Ranch, which owns the 40-acre farm in Christiana, outside of Nashville, believes cattle-grazing is the next frontier in so-called agrivoltaics, which mostly has involved growing crops or grazing sheep beneath the panels. The solar company debuted the project this week and will spend the next year working to demonstrate to farmers that much larger cattle also can thrive at solar sites. If successful, advocates say, that could jump-start new projects to meet the soaring electricity demand driven by rapidly expanding data centers — with...

By Julia Simon, NPR.  Excerpt: ...Colombia is a major global coal producer, as well as an oil and gas producer. But in recent years, Colombia's government has been diversifying its economy and  transitioning away from fossil fuels , the single biggest driver of human-caused climate change. The country isn't alone. This week, Colombia and the Netherlands—the birthplace of oil giant Shell—co-hosted the "Transitioning Away from Fossil Fuels conference" in Santa Marta, just north of the coal port. At a hotel by the sea, representatives of more than 50 countries participated in a two-day high-level conference to discuss concrete ways to phase out oil, gas, and coal. ...These high-level talks happened amidst the backdrop of a warming planet and an energy crisis spurred by the U.S.-Israeli war in Iran. High oil and gas prices and energy shortages triggered by the recent war have created what the executive director of the International Energy Agency, Fatih Birol, has called ...

By Jeffrey Mervis , Science.  Excerpt: Dismissal of the National Science Board is widely seen as latest move to erase NSF’s independence. ...Keivan Stassun, one of the dismissed board members, says the mass firing is the latest indication the White House is ignoring the board’s authority and dictating policies at NSF, which has been without a permanent director since  Sethuraman Panchanathan resigned  exactly 1 year ago. Stassun, an astrophysicist at Vanderbilt University who was appointed to the board in 2022, thinks the board’s public criticism in May 2025 of Trump’s proposed 55% cut to NSF’s current budget—which Congress ultimately ignored—antagonized the administration. “Maybe one way to say it from the administration's perspective,” Stassun says, “is that this group of presidential appointees was advising the Congress to not follow the president's wishes.”...  Full article at https://www.science.org/content/article/trump-fires-nsf-s-oversight-board .

By Damien Gayle , The Guardian.  Excerpt: The UK government vastly underestimated the climate impact of artificial intelligence, it has emerged, after officials raised their estimate of carbon emissions from AI by a factor of more than 100. According to new data quietly published this week, energy use by AI datacentres in the UK could cause the emission of up to 123m tonnes of carbon dioxide (CO₂) ...over the next 10 years. That latest figure replaces a previous estimate ...that claimed emissions would reach a maximum of 0.142m tonnes of CO₂ in a single year. There is  increasing alarm  at the carbon impact of AI and with calls to reduce global emissions to mitigate the climate emergency becoming increasingly urgent. ... The latest estimates were revealed in a  revision  to the UK “compute roadmap”, which sets out the government’s plan “to build a world-class compute ecosystem” for delivering artificial intelligence in the UK.... However, AI datacentres require ...

By Jelle Soons and Henk A. Dijkstra , Science.  Abstract: The Atlantic Meridional Overturning Circulation (AMOC) is a major tipping element in the present-day climate and could potentially collapse under sufficient freshwater or CO 2 forcing [from melting glaciers]. While the effect of the Bering Strait on AMOC stability has been well studied, it is unknown whether a constructed closure of this Strait can prevent an AMOC collapse under climate change. Here, we show in an Earth system Model of Intermediate Complexity that an artificial closure of the Strait can extend the safe carbon budget of the AMOC, provided that the AMOC is strong enough at the closure time. ...constructing this closure could be a feasible climate intervention strategy to prevent an AMOC collapse....  Full article at https://www.science.org/doi/10.1126/sciadv.aeb7887 . 

By Bob Berwyn , Inside Climate News.  Excerpt: ...more than 50 nations are  gathering in Santa Marta , Colombia, today to start mapping out specific plans to phase out fossil fuels, going beyond the conditional global consensus on “transitioning away from fossil fuels in energy systems” reached at COP28 in Dubai. A lack of progress toward that goal spurred Colombia and the Netherlands to build a coalition of countries willing to move faster and farther. Attending countries span a spectrum from influential fossil fuel producers like Australia, Norway, Brazil, Nigeria and Mexico to climate-vulnerable island nations including Fiji, Tuvalu and the Maldives, as well as Denmark, Spain and France and the European Union. Notably absent are the United States, Russia, China and major Gulf petrostates such as Saudi Arabia and the United Arab Emirates. Offering a perspective from  The Elders , a group of former independent world leaders that acts as a moral and ethical voice on issue...
