CLIMATE
A large portion of the Birch Glacier in Switzerland broke free on Wednesday. Nine million tonnes of ice and granite plunged into the Lötschental valley destroying most of Blatten, a village of 300. The residents and their animals had been evacuated 9 days earlier. Current global warming loosened the permafrost and ice that held the Kleines Nesthorn peak and the Birch Glacier in place likely for more than 60,000 years. Similar rockslides are happening around the world at an increasing pace.
Melting permafrost is affecting many arctic communities, such as Tuktoyaktuk on the shore of Lake Tiktalik in Canada. [¿Does Tiktalik sound familiar? Tiktaalik could be our fishapod ancestor.]
Unparalleled wildfires rage out of control in Alberta, Saskatchewan, and Manitoba forcing the evacuation of over 25,000 residents. Smoke is beginning to cover vast areas of the northern United States.
Here in the U.S., Federal agencies have been forbidden to track costs attributable to climate change. White House administrator Jeffrey B. Clark explained there are uncertainties whether “any supposed changes in the climate are actually occurring as a consequence of anthropogenic greenhouse gas emissions.” His statement flies in the face of hundreds of scientific studies that concluded otherwise.
RAFFLE
We are offering a metal model kit of JWST: 10.5cm long & 7cm high (after assembly with stand). Just send an email before noon Friday to david.almandsmith [at] gmail.com with your guess of an integer between 0 and 1,000. Last time, Brian won a glass ball barometer. Of the 16 contestants, his guess of 79 was closest to the randomly-generated 58.
CHEMISTRY
I grew up thinking that “ironwood” came from a specific ironwood tree. As it turns out, there are over a hundred tree species that have wood denser than water and earn the sobriquet of ironwood. Now there is a literal ironwood: wood infused with nanocrystals of ferrihydrite. The result is a superior building material. After treatment, the wood is 127% harder and 260% stronger. ¿But will it rust?
Last April, the Biden Administration set limits on the maximum concentration of PFAS - polyfluoroalkyl substances - in our drinking water to go into effect in 2029. The current administration has changed the compliance date to 2031 for PFOA and PFOS, and removed limits on other PFAS chemicals: PFHxS, PFNA, HFPO-DA, and PFBS.

GEOLOGY
Amazing! In addition to using seismometers to study earthquakes, seismologists are employing fiber-optic cable. Here’s what was done on the Peninsula (approximately):
A tiny Fiber Bragg Grating (FBG) sensor was located every 100 meters on a 10 km length of fiber-optic cable.
The cable was buried along a 10km stretch of the Peninsula.
An oven-sized piece of equipment called an interrogator continuously sent short light pulses from one end of the cable.
The interrogator recorded the amount of time it took for a portion of each light pulse to be reflected back from each FBG.
A change in length smaller than a micrometer anywhere along the cable was detectable.
As a seismic wave travels along the Peninsula, the buried cable is alternately stretched and compressed. The interrogator records that activity from each of the 1,000 FBGs. It was so sensitive, the seismologists were able to track the travel of CalTrains. The seismic wave from a small earthquake in Gilroy was neatly recorded as it travelled up the Peninsula. To record seismic waves from all directions requires that the fiber-optic cable be laid in up-down and side-to-side orientations.

“Empathy is not pity nor is it compassion. Empathy is the ability to take on another’s perspective as if it were your own - if only for a moment - regardless whether you are comfortable with that perspective. With practice, we can expand our reach to experience empathy with anyone and any living thing. For those among us who strive for power, empathy can be a hindrance. For those among us who strive for a better world, empathy is vastly powerful.”

Quintupling global energy end-use efficiency by integrative design - 06/02/2025 04:30 PM
Stanford University Energy Seminar Stanford
Switching from fossil and nuclear power to cheaper solar and windpower can double or triple primary energy efficiency. Most analysts think another doubling is available in further conversion to delivered global energy services. But "integrative design" can raise that twofold to fivefold by optimizing buildings, vehicles, and factories as whole systems for multiple benefits, not as isolated parts for single benefits. Practical examples illustrate this proven, profitable, and powerful way to make the transition to clean energy severalfold quicker, cheaper, and easier.

Revealing Dark Matter with Strong Gravitational Lensing - 06/02/2025 07:30 PM
California Academy of Sciences San Francisco
The overwhelming majority of matter in our Universe is believed to be an unknown new ‘dark’ particle that exists outside the standard model of physics and does not interact with light. An important goal of modern physics is to understand what this particle is. Dr. Nierenberg will provide an overview of the observational evidence for the existence of dark matter, introduce strong gravitational lensing - where space-time is bent by massive objects - and conclude by explaining how we are using this phenomenon to gain new insights into the nature of dark matter with the James Webb Space Telescope, Hubble Space Telescope, and Keck Observatories.

Triggering the Unknown: Model-Independent Discovery with Intelligent Detectors - 06/03/2025 03:30 PM
Hewlett Teaching Center Stanford
At the Large Hadron Collider (LHC), the coming decade will see discovery potential determined not only by luminosity but by the intelligence embedded inside the detector itself. In the absence of any clear signs for physics beyond the standard model, two options remain: either new physics is beyond the reach at the LHC or we are not looking in the right places. In response, new colliders have been proposed to take us beyond the LHC physics reach and new theoretical models (e.g. dark sector) have been proposed with signatures that could be hiding amongst the trillions upon trillions of proton interactions that take place at the LHC. The Compact Muon Solenoid (CMS) is a general-purpose detector at the LHC that sees petabytes worth of data each second during proton-proton collisions. At CMS a real-time trigger system built upon FPGAs is used to select interesting interactions. Recently this system has begun to incorporate unsupervised machine learning to flag anomalous events within nanoseconds for further analysis. This talk explores recent developments in trigger-level anomaly detection, including FPGA-deployed networks and the broader integration of graph networks, quantized transformers, and ASICs. These innovations point the way toward scalable, intelligent data selection for the HL-LHC, Future Circular Collider (RCC), and future muon colliders, enabling a broader, more agnostic approach to discovery.

Muscle, The Stuff that Moves Us and Why It Matters - 06/03/2025 05:30 PM
Commonwealth Club San Francisco
Join us for an intriguing look at muscle power - and the surprising ways muscle can reveal what we’re capable of.
Bonnie Tsui, author of On Muscle, will be joined by filmmaker Paige Bethmann and the subject of Bethmann’s documentary, Ku Stevens. Her film, Remaining Native, tells the story of 17-year-old runner Stevens who made a 50-mile run through the Nevada desert to remember the route his great-grandfather’s took to escape from a boarding school.
Tsui will draw on a blend of science, culture, immersive reporting, and personal narrative to examine not just what muscles are but what they mean to humans. Muscles allow our heart to beat, food to move through our bodies, blood to circulate, even babies to leave the womb.
We might not think of our muscles unless they are sore or we are working out. But they connect us with just about everything we do. Join us in-person or online for an enlightening discussion.

Good Grief: The 10 Steps - Film Screening and Climate Anxiety Workshop - 06/04/2025 01:00 PM
Commonwealth Club San Francisco
The Climate One radio show and podcast explores the many dimensions of the climate crisis. But sometimes the most meaningful conversations happen when the microphones are off - when we gather to reflect and connect in a room together. For this special in-person event, we’re doing things a little differently. Join us for a screening of the 40-minute documentary Good Grief: The 10 Steps, followed by a conversation with the filmmakers and a resource-building workshop designed to help us process, connect and support one another. This event will not be recorded.
Good Grief: The 10 Steps is a poignant and revealing documentary that delves into the transformative journey of individuals grappling with despair over climate change and the polycrisis. Centered around the Good Grief Network, an innovative peer-to-peer support program, participants lean into their painful feelings and in the process find joy, connection and a renewed sense of possibility. The film is a testament to the power of community and the potential for personal healing through shared understanding and collective action.

The EARNEST Consortium, sponsored by the U.S. Department of Energy (DOE), is dedicated to identifying and advancing solutions for the future of the U.S. electricity system. As part of its public engagement, EARNEST is launching its first webinar series, focused on “U.S. Grid Reliability and Resilience.”
This third session will feature research from the EARNEST team at the University of Texas at Austin, addressing growing concerns about grid reliability in Texas.
In recent years, Texas has faced mounting challenges from extreme weather events, such as winter storms and heat waves, that have exposed vulnerabilities in the state’s power infrastructure. While solutions such as energy efficiency, demand response, and distributed energy resources have been widely discussed, another promising option is the development of interregional transmission that connects the Texas grid with other U.S. grids.
To evaluate this strategy, the research team developed a novel framework to model how the Texas grid might evolve with access to various interregional ties. The framework also enables stress testing of the grid by simulating how it would perform under extreme events like a severe winter storm, offering new insights into grid resilience and system planning.

How Rocks on Mars Tell the Story of a Vanishing Climate - Livestream - 06/05/2025 02:30 PM
SETI Live
Join planetary scientist Beth Johnson as we explore a groundbreaking discovery from NASA's Curiosity rover on Mars. Scientists have identified siderite - a rare iron carbonate mineral - within ancient Martian rocks, offering new insights into Mars' once-thicker atmosphere and its now-lost carbon cycle. This discovery reshapes our understanding of the Red Planet's climate history and helps us draw powerful parallels to Earth's carbon processes.
Dr. Ben Tutolo, associate professor at the University of Calgary and participating scientist on NASA's Curiosity rover team, explains that as Mars' atmosphere thinned over time, carbon dioxide was sequestered into rock formations, leading to a dramatic climate shift from a warm, wet environment to the cold, arid planet we see today. These findings not only provide evidence that ancient Mars was habitable but also offer insights into the fragility of planetary climates. Dr. Tutolo emphasizes the parallels between Mars' atmospheric changes and current efforts on Earth to mitigate climate change by converting anthropogenic CO? into stable carbonates. Understanding the mechanisms of carbon sequestration on Mars could inform strategies to address climate challenges on our own planet.
