Months before catastrophic floods swept through an Alaska Native village on Sunday, the Trump administration canceled a $20 million grant meant to protect the community from extreme flooding. At the time, the EPA administrator said he was eliminating "wasteful DEI and Environmental Justice grants."
E.P.A. Canceled $20 Million Flood Protection Grant to Alaska, Parts of Which Just Flooded
The remote village of Kipnuk planned to use the money to protect against flooding. On Sunday, it was inundated.

Increasing wildfire frequency decreases carbon storage and leads to regeneration failure in Alaskan boreal forests fireecology.springeropen.com/articles/10....
Increasing wildfire frequency decreases carbon storage and leads to regeneration failure in Alaskan boreal forests - Fire Ecology
Background The increasing size, severity, and frequency of wildfires is one of the most rapid ways climate warming could alter the structure and function of high-latitude ecosystems. Historically, boreal forests in western North America had fire return intervals (FRI) of 70–130 years, but shortened FRIs are becoming increasingly common under extreme weather conditions. Here, we quantified pre-fire and post-fire C pools and C losses and assessed post-fire seedling regeneration in long (> 70 years), intermediate (30–70 years), and short (< 30 years) FRIs, and triple (three fires in < 70 years) burns. As boreal forests store a significant portion of the global terrestrial carbon (C) pool, understanding the impacts of shortened FRIs on these ecosystems is critical for predicting the global C balance and feedbacks to climate. Results Using a spatially extensive dataset of 555 plots from 31 separate fires in Interior Alaska, our study demonstrates that shortened FRIs decrease the C storage capacity of boreal forests through loss of legacy C and regeneration failure. Total wildfire C emissions were similar among FRI classes, ranging from 2.5 to 3.5 kg C m−2. However, shortened FRIs lost proportionally more of their pre-fire C pools, resulting in substantially lower post-fire C pools than long FRIs. Shortened FRIs also resulted in the combustion of legacy C, defined as C that escaped combustion in one or more previous fires. We found that post-fire successional trajectories were impacted by FRI, with ~ 65% of short FRIs and triple burns experiencing regeneration failure. Conclusions Our study highlights the structural and functional vulnerability of boreal forests to increasing fire frequency. Shortened FRIs and the combustion of legacy C can shift boreal ecosystems from a net C sink or neutral to a net C source to the atmosphere and increase the risk of transitions to non-forested states. These changes could have profound implications for the boreal C-climate feedback and underscore the need for adaptive management strategies that prioritize the structural and functional resilience of boreal forest ecosystems to expected increases in fire frequency.

MIT says no to the Trump admin higher-ed compact clearly and emphatically. Other universities would be well served to read, remix, and respond similarly.

"In that free marketplace of ideas, the people of MIT gladly compete with the very best, without preferences."

MIT's response to the Trump admin's proposed "compact" is excellent and should be a model for other universities. orgchart.mit.edu/letters/rega...

Roger Pielke Jr spent years moaning about being "cancelled", and now he's just spending his days at a fossil-funded think tank directly attacking climate scientists, and he has a fascist dictatorship to help him out now too

So seriously gross

Climate critics try to discredit IPCC author for linking disasters to global warming
By Lesley Clark, Sara Schonhardt, Chelsea Harvey | 10/09/2025 06:22 AM EDT

Roger Pielke Jr. and oil industry supporters are attacking climate scientist Friederike Otto, whose work has been used in lawsuits against polluters.

Fossil fuel industry allies have launched a campaign against the inclusion of scientist Friederike Otto in the next United Nations climate review. They say her work to attribute extreme weather to human-caused global warming is bolstering climate lawsuits against oil companies. The First/Facebook | The First/Facebook

Critics of mainstream climate science and allies of the fossil fuel industry are taking aim at a prominent expert who’s helping coordinate the next United Nations review of global climate research, arguing that her work aims to bolster multibillion-dollar lawsuits against oil and gas companies.

In an August New York Post op-ed, Roger Pielke Jr., a political scientist at the conservative think tank American Enterprise Institute, raised concerns about the appointment of Friederike Otto as a coordinating lead author for the seventh assessment report of the influential Intergovernmental Panel on Climate Change.

The criticism is aimed at extreme weather attribution, a popular field of research that studies whether and to what degree human-caused global warming has made an extreme weather event, such as a heat wave or heavy rain, more severe or likely to occur. Otto co-founded World Weather Attribution, which develops analyses showing climate’s role in extreme weather events.

Life would be impossible without experts — doctors help us when we get sick, mechanics fix our cars when they break down, farmers produce our food, to name just a few.

But we live in a time when too many of these roles have become politicized.

President Trump recently fired the head of the Bureau of Labor Statistics after the agency released a jobs report he did not like. Similarly, soon after his election, President Joe Biden fired the climate scientist leading the US National Climate Assessment and replaced her with a communications professional.   

Not surprisingly, public confidence in medical and scientific institutions has dropped overall and become more partisan as politicians increasingly select experts to advise them based on their politics rather than their willingness to call things as they see them.

The ongoing politicization of scientific institutions is not limited to politicians or to the United States.

Now we’re seeing it in the organization tasked with periodically assessing climate science under the United Nations, the Intergovernmental Panel on Climate Change, which distills the thousands and thousands of research papers on climate change to help inform decision-makers on the nature of the problem and possibilities for response.

The IPCC is so important for clarifying what we know and don’t know about climate that I have testified before Congress that if it didn’t exist, we would have to invent it.

Last week, the IPCC announced its list of authors for its seventh assessment report, which is just getting underway and will take several years to produce.

One of its most important chapters is on extreme weather events — how they may have changed over time, and understanding the reasons for any identified changes.

USGS scientists tell us about the effects of invasive species & climate change. Yet their fate, like many other federal employees who work in science & the environment, is unknown. My latest for @nrdc.org. Thank you to @meadekrosby.bsky.social, John Organ, Ed Arnett, and others for speaking with me.

⚠️new(-ish) paper in Journal of Climate⚠️ i evaluated CMIP6 models' Pacific decadal SST variability and teleconnections... big takeaway is that models under-simulate temporal PDO/IPO variability on decadal timescales, likely affecting precip trends in the Southwest

An unprecedented violation of our civic and Constitutional traditions. Calling every military leader in the world back to the U.S. to hear a wildly inappropriate partisan campaign speech followed by a fascist call to use the military against Americans.
