Endangerment of natural ecosystems by #climatechange caused by #greenhousegases from human activities - my report to current U.S. administration, presenting strong scientific evidence supporting 2009 U.S. Environmental Protection Agency #endangerment finding www.patrickgonzalez.net/images/Gonza...

In 2024, global #renewable power capacity reached 4,448 GW—an increase of 15% in just one year. 91% of new projects outpriced fossil fuels, avoiding approx. $57 billion in costs. Clean energy is no longer an option—it’s the new economic baseline. bit.ly/4lGceLK

91% of New Renewable Projects Now Cheaper Than Fossil Fuels Alternatives Renewables maintain their cost leadership in global power markets, IRENA’s new report on Renewable Power Generation Costs in 2024 confirms.

🚨📢 New IRENA data shows that in 2024, 91% of newly commissioned renewable power capacity delivered electricity at a lower cost than the cheapest fossil fuel-fired option.
Renewables remain cost competitive while supporting energy security and economic stability. Read: bit.ly/3TSg6gE

IPCC selects UC Berkeley scientist for climate change assessment - Berkeley News The Intergovernmental Panel on Climate Change (IPCC) produces the authoritative scientific assessments that guide global policy and action on human-caused climate change.

The @ipcc.bsky.social has selected UC Berkeley climate change scientist and forest ecologist Patrick Gonzalez as a lead author on its next global scientific assessment of climate change. news.berkeley.edu/2025/08/22/i...

Gonzalez has served as a lead author on four previous IPCC reports. For the upcoming assessment, he is part of a team producing the North America chapter of the volume on climate change impacts, adaptation and vulnerability.

“It’s an honor to advance climate change science and solutions as part of the Intergovernmental Panel on Climate Change,” Gonzalez said. “This work provides a strong foundation for innovative policies and meaningful efforts to halt climate change.”

Honored to be selected again by the Intergovernmental Panel on Climate Change @ipcc.bsky.social as a lead author, for the next science assessment of #climatechange www.ipcc.ch/2025/08/18/p..., providing a strong science basis for policy and action to halt human-caused climate change.

Time for Congress to save American science…and the nation "We believe the best hope for saving science and, perhaps, saving our form of democracy, is convincing at least a couple dozen Republican members of Congress that it’s up to them—that the stakes require exercising the prerogatives of the Congress to constrain excesses by the Executive Branch and resuming the serious conversations, debates, and compromise across the aisle and between the branches that used to be the way policy was made."

The impacts of Trump's campaign against American science will likely be profound, write John P. Holdren and Neal Lane.

"The rapidly growing damage to the scientific pillar of American well-being and influence requires that Republican members of Congress stand up to rein Trump in."

The Gorgeous, Unglamorous Work of Freedom Notes from an “actualist” on what liberation requires

Walls really do tumble. But the cause of freedom is a call to action for each new generation, Bono writes.

Jimmy Carter, 39th president and Nobel Peace Prize winner, dies at 100, his son says The tenacious Southerner was turned out of office after one term. But he had a brilliant post-presidential career as a champion of health, peace and democracy.

After being elected president in 1976 and serving only one term, Jimmy Carter went on to have an extraordinary life that included a Nobel Peace Prize.

Threaded here is his story. wapo.st/49ZLa55

E.P.A. Bans Perc and T.C.E., Two Chemicals Used In Dry Cleaning The two solvents, known as Perc and TCE, cause kidney cancer and other ailments, and have been the subject of years of controversy.

Breaking News: The EPA banned two solvents found in everyday products and used in dry cleaning that can cause cancer and other serious diseases.
