The U.S. will not attend the annual UN climate summit, COP30, which kicks off on Thursday in Brazil. And that's just fine for those who see the Trump administration’s hostility toward anything related to climate change as a menace to international cooperation.

NEW: Billions of pounds of food are imported to the U.S. each year.

The FDA inspects foreign producers to ensure what we're eating is safe from pathogens and dangerous manufacturing practices.

But now, after Trump's drastic staff cuts, these inspections have plummeted to a historic low.

The current government shutdown is now officially the longest in U.S. history, surpassing the 35-day shutdown of President Trump’s first term. The impact of the shutdown, having lasted 35 full days, has already been felt across the country. nyti.ms/3Xaygvt

Congress’ path to irrelevance did not begin during the #shutdown. It is the result of decades of erosion that created a political culture in which Congress is relegated to second-class status, according to a political scientist. buff.ly/8hYHW3j
The shutdown – and the House’s inaction – helps pave Congress’ path to irrelevance
With major shutdown impacts beginning to set in, a scholar of Congress says the House has all but abdicated its position as ‘The People’s Chamber.’

A newly released Global Tipping Points report suggested that coral reefs have passed thresholds beyond which they can't bounce back.

Our new study from Fiji shows just the opposite - astonishing, rapid recovery within 4 years of reefs pummeled by a category 5 cyclone.

#ForCoral
We are standing at a tipping point, but also at the edge of a powerful opportunity #ForCoral.

Coral reefs are under unprecedented stress. But this is not the end of the story.

New research co-authored by WCS shows that some reefs can still recover, even after catastrophic damage. bit.ly/47ojYfG 🌏

A huge shoutout to all the dedicated grants management specialists at the NIH who are working around the clock to push grants out before the Sep 30 deadline. And also to the POs responding to frantic emails.
Not an easy job under the best of circumstances and right now it's the pits.
Thank you!

The collapse of the AMOC would be Catastrophic.

More than 85 American and international scientists have denounced a Trump administration report that calls the threat of climate change overblown, saying the analysis is riddled with errors, misrepresentations and cherry-picked data to fit the president’s agenda.
