Maybe only a small act, still good to show broad concern - union of concerned scientists is seeking signatures on a letter urging congress and administration to ensure that NOAA and its sub-agencies remain fully funded and staffed act.ucsusa.org/4kajJuk

Climate change is the biggest crisis humanity faces in the 21st century and just because they are trying to eliminate all mentions of the word “climate“ doesn’t actually solve anything.

A throwback #FireScarFriday to this special catface I visited last fall in the redwoods. It had a short informational trail with some cool diagrams of tree rings and scar evidence. Science in the woods is 🔥🔥🔥

This well-referenced page includes personal stories from those terminated, with links to share your story. Congressman Ro Khanna and the House Science Committee are surveying the impact of these cuts.

How do we restore the natural world? There is no single answer—in fact, there are a multitude of ways to engage & be #GenerationRestoration. Whether big or small, every effort makes a huge difference. Here are three ways to help nature thrive: www.decadeonrestoration.org/ecosystem-re...

Amazing opportunity for #science teachers. #Indigenous knowledge is the original long-term data set. 🧪

Ornithology folks, here is a VERY cool job opportunity that appears to be relatively independent of the federal $h!t $h0w. Do you just love research and birds and want to get on with saving the world? apply here: academicjobsonline.org/ajo/jobs/29599

Trucks move billions of tons of cargo each year—including those Valentine’s chocolates you ate. But, trucks are also responsible for a massive amount of air pollution from on-road vehicles. Electric trucks are on the road NOW. Accelerating their deployment saves lives & money. ⚡🚚❤️ #ZeroMustMeanZero

Publication of the National Nature Assessment, a first-of-its-kind report on nature's value, was stopped by the Trump admin. @chrfield.bsky.social stresses its importance: "until we do this, we don't really have an accurate assessment of what it is we're working with." Read more: abc7ne.ws/3EKCXX0

So many incredible federal scientists were unfairly fired this week. We're already feeling the the loss of their expertise, and those impacts will continue to grow #standupforscience2025 🌎🔥🧪

February 20 is the next event in the 2025 Women Advancing River Research Seminar Series Climate, Water, and Society: Unraveling Complex Interactions Through Decision-Relevant Climate Information will be presented by Antonia Hadjimichael and Penelope Mitchell. Details: bit.ly/3Sxz7nx

"Now is the time for science, not silence." The war on science isn’t just politics, it’s our planet's future & the stakes have never been higher.🦈🪸🌊 As climate scientists, we must advocate & defend evidence-based policy.📄🌏 #ClimateAction #ScienceMatters www.science.org/doi/10.1126/... @science.org

Let's show some love for the Yellow-breasted Bunting.💛 Once abundant across Europe & Asia, this little songbird is now critically endangered. From grasslands to wetlands, every habitat they call home needs protection. 🌍🧪 Let's keep their song alive! 🐦

*New paper* Denialism campaigns are growing in attempts to discredit science, scientists, and the scientific process generally. Biodiversity loss denial is a new phenomenon that needs our attention. -With @alexanderlees.bsky.social + Eliza Grames! #CommSky 🧪🌏 www.sciencedirect.com/science/arti...

Smith et al. found that trust builds conservation success, even if relationships are long-distance. In conservation, people and their relationships to each other are critical elements of success. conbio.onlinelibrary.wiley.com/doi/10.1111/...

Humanity relies on nature for survival but also threatens it, putting over one million species at risk of extinction. The #GlobalGoals are key in addressing this & restoring ecosystems: www.un.org/sustainabled...

Here is the issue that has caused so many headaches among climate mitigation researchers - inventory estimates of net land use change emissions differ substantially from global bookkeeping models. lambwf.github.io/UNEP-Gap-Rep...

Not Jeremy's point, but the life expectancy for Natives hasn't budged while others are increasing. My dad (Inupiaq) just celebrated his 88th bday, he's such a trendsetter

Did you know the most powerful force for climate action is LOVE—for our children, their future, and the world they’ll inherit? That's right! Research shows this message moves hearts 12x more than jobs and 2x more than extreme weather. Source: potentialenergycoalition.org/guides-and-r...

We are recruiting a postdoctoral ORISE fellow to join an interdisciplinary team focused on issues of ecosystem type conversion, directional biodiversity change, and what to do about it. Please spread the word! 🌎🌐🧪 Details here: www.zintellect.com/Opportunity/...

We have a new paper out "Die-off after an extreme hot-drought affects trees with physiological performance constrained by a more stressful abiotic niche" @csic.es Free access link authors.elsevier.com/c/1kZozcFXJo... #WhatKillsTrees

"Springwood and earlywood form the annual growth rings which foresters use to age trees." Great information about #forest management from University of #NewHampshire #Extension.

DC peeps, time to show up to protect EPA — Clean Air Act❗️Clean Water Act❗️Superfund Act*❗️Toxic Substances Control Act❗️ If you want these glorious acts of Congress implemented, we must protect EPA. Thank you Senator Markey for leading the charge 💚 www.mobilize.us/climateactio...

Is the delta smelt fish to blame for lack of water to fight the #LAwildfires? The real issue lies elsewhere, according to @feliciamarcus.bsky.social. Trump's Jan. 24 executive order to put the federal govt in charge of managing CA water would "put less [water] in L.A. fire hydrants." bit.ly/4aTc3rZ

Sabotage. Criminal sabotage. "[The NSF] is planning to lay off between a quarter and a half of its staff in the next two months, a top National Science Foundation official said Tuesday." www.eenews.net/articles/sci...

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

The US Senate Finance Committee voted to advance Robert F. Kennedy Jr.’s nomination to lead HHS. Sen. Cassidy cast the deciding vote, setting aside his medical training to approve a conspiracy theorist with no science training. This is unacceptable, RFK Jr. should be disqualified:

In Hubbard Brook, early warning signals—shifts in stream calcium and nitrate levels—are telling a story of transformation. As decades of acid rain and #climate stress take their toll, researchers are monitoring the #ecosystem's ability to recover or transition to a new state. #CriticalZone 🧪

Exciting news! We’re thrilled to announce that tapir Yuna gave birth to a rare and endangered Malayan tapir calf Sunday night. The newborn, covered in distinctive white spots and stripes resembling a fuzzy walking watermelon, is only the second tapir born in our 120-year history.

Scientists recently performed the largest-ever assessment of fire scars to better understand forest fire history across North America. 🧪🏺🌲 The researchers studied scars from 1750-1880 CE to understand fires before the modern “fire suppression” era. New from me @newscientist.com
