‘Trump Doesn’t Represent Us’: U.S. Activist Groups to Push for Climate action At Cop30 in Brazil

Introduction:

(The Guardian) Despite historic environmental rollbacks under a president who pulled the US from a key international climate treaty – and recently called global warming “the greatest con job ever perpetrated on the world” – US civil society groups say they are gearing up to push for bold international climate action at a major UN conference next month.

“This is a really important moment to illustrate that Trump does not represent the entirety, or even anywhere near a majority, of us,” said Collin Rees, US program manager at the environmental non-profit Oil Change International, who will attend the annual UN climate conference, known as Cop30.

The negotiations will take place in the Brazilian city of Belém near the Amazon delta. It is expected to convene delegations from nearly every government in the world to discuss the implementation of the 2015 Paris climate agreement.

Trump, who began the process of pulling the US from the Paris accord on his first day in office, is not expected to send a delegation to the negotiations. But hundreds of US activist organizations are planning to attend, despite widespread logistical challenges and high accommodation costs in a region with limited tourist infrastructure.

“Yes, the federal administration has changed radically … but the actual US climate movement is still here,” said John Noel, senior strategist at Greenpeace International who formerly worked on the US team.

Six-million-year-old Antarctic ice offers rare glimpse into Earth's past
By Pranjal Malewar
November 13, 2025

Antarctica's ice cores are like frozen diaries of Earth's past, preserving ancient air and climate clues. Most continuous records go back about 800,000 years. But in a region called the Allan Hills, a special patch of blue ice holds scattered snapshots dating back as far as 2.7 million years.

Now, US scientists have uncovered something extraordinary: the oldest directly dated ice and air ever found, thought to be up to 6 million years old. By studying tiny air bubbles and measuring a rare gas called argon-40, they've cracked open a window into Earth's deep past.

This ancient Antarctic ice isn't just old, it’s a time machine. Scientists found that this ancient ice offers a rare peek into Earth's climate long before humans walked the planet. Back then, the world was much warmer, and sea levels were much higher than they are today.

These COPs have been a joke for the last decade or so. Blatantly hijacked by fossil fuel interests, whose delegations now outnumber the national delegates. Almost zero progress in 30 years of negotiations. At this point they might actually be doing more harm than good, given the sheer amount of carbon emissions from all the attendees flying in, etc.

Experts warn ongoing concern with Atlantic Ocean will be direct threat to dozens of nations: 'Consequences for at least 1,000 years to come'

Tue, December 16, 2025

A new study has concluded that the collapse of a "prominent and powerful" ocean current would have serious impacts on Europe.

This marks the first time researchers have tested multiple climate scenarios to see how Europe's summer precipitation might respond if the important conveyor belt that transfers heat from the tropical Atlantic toward higher latitudes in the Northern Hemisphere fails.

"The Atlantic Meridional Overturning Circulation (AMOC) is expected to weaken or even collapse under anthropogenic climate change," wrote the authors of the study. "Given the importance of the AMOC in the present-day climate, this would potentially lead to substantial changes in the future projections of the impacts of climate change on regional weather, which is highly relevant for society."

The study, titled "Changing European hydroclimate under a collapsed AMOC in the Community Earth System Model," was conducted by scientists with the Royal Netherlands Meteorological Institute.

The researchers revealed that Southern Europe's recent hot, dry summers could become even more intense over the next 1,000 years if the AMOC collapses, leading to deeper droughts and longer dry spells in the region.

Climate Change Has Already Taken a Toll on American’s Income
December 20, 2025

Introduction:

(University of Arizona Via Futurity) Derek Lemoine, a professor of economics in the Eller College of Management at the University of Arizona and codirector of the university’s Consortium of Environmentally Resilient Business, says measuring climate change’s current economic impact has big-picture implications when it comes to policymaking and business investment.

“If we can’t figure out what climate change is already costing us with the data we have, projecting the future becomes almost hopeless,” says Lemoine, lead author of the study published today in the journal Proceedings of the National Academy of Sciences.

Lemoine adds that previous research largely focused on local, short-term weather changes alone, which, by his model, had a negative impact on US income of less than 1%. When he accounted for climate change’s year-after-year persistence and nationwide reach as well as connections between regional economies, the income loss jumped to about 12%—comparable to a major national policy shift. While the exact number is uncertain, Lemoine says the true effect is clearly far larger than 1%.

“A lot of the real cost comes from how temperature changes across the whole country ripple through prices and trade,” he adds. “It’s not just about the weather where we live. When every region is affected at the same time, the economic consequences add up quickly.”

To measure climate change as an ongoing economic force, Lemoine worked with climate models simulating the world with and without human emissions to figure out how different each county’s weather would have been if there was no climate change. He then combined county-level data on daily temperature with county-level personal income per capita from the Bureau of Economic Analysis covering 1969-2019. By doing this, he was able to measure how income historically changed with the number of hotter and colder days both locally and around the country, giving him a more detailed picture of the economic effects of shifting temperature patterns
