Tomorrow is Day 1 of the Light Pollution: Theory, Modeling and Measurement (LPTMM) 2026 meeting in Ensenada, Mexico. Sadly this time I won't be able to join the crew in person, but I'll be listening in from home via the series of tubes known as the Interwebz.
On Friday, I'm excited to (remotely) moderate a roundtable discussion, the anticipated outcome of which is a consensus that it's time to take meaningful next steps toward standardizing measurement methods, reporting and units in light pollution studies.

🌟 Ah, yes, because what everyone truly craves is a #JavaScript masterpiece allowing us to simulate light pollution on our screens. 🙄 Who needs clear skies or real stargazing when you can drown in digital glare? 🚀✨

New research shows our planet’s night is more volatile than ever.
A decade of satellite data reveals that while some areas are dimming due to policy changes or crisis, others are brightening at a rate that keeps the global average of light pollution rising by 2% annually.
It’s time to move from studying the glow to taking action. Read more: https://www.darkskyconsulting.com/blog/decoding-a-decade-of-rising-global-light-pollution

Artificial light at night not only changes the landscape, it also deeply interferes with natural #ecosystems. A recent study shows that #lightpollution can significantly affect the energy and nutrient exchange between bodies of water and adjacent riparian habitats – more than non-native species. Lighting along riverbanks or streams can thus have far-reaching ecological consequences. The results were published in the journal 'Functional Ecology'.

How do increased light levels, night sky brightness and cooler light colors affect #wildlife? Try out yourself by using this simulation. How do owls or hedgehogs perceive this environment? See the scene through their eyes by opening this application on a desktop browser.

“International Dark Sky Week is hailed as a global celebration of the night and a call for less light pollution. In some cities internationally, local governments are trying to find a solution to lighting the night can better serve critical wildlife ecosystems and humans alike. Malcolm Brabant reports from Denmark.” #lightpollution

Light pollution encroaching on darkness
"The planet’s artificial light increased by a net 16% between 2014 and 2022.The figure is in keeping with a 2017 study that found Earth’s artificially lit outdoor areas grew by 2% annually over the previous five years, and that light pollution encroached on darkness almost everywhere." >>

This legislation, if signed into law by the U.S. President, will have a direct and harmful effect on conditions at a designated International Dark Sky Sanctuary.

“Insects are helping everything else work as part of intricate, coevolved systems. You can’t just pull individual organisms from ecosystems and expect everything to keep going,” says Alex Wild, curator of entomology at the University of Texas Biodiversity Collections.

Losing the Dark - Flat Screen Version
"Starry skies are a vanishing treasure because light pollution is washing away our view of the cosmos. It not only threatens astronomy, it disrupts wildlife, and affects human health. The yellow glows over cities and towns — seen so clearly from space — are testament to the billions spent in wasted energy from lighting up the sky.
"To help raise public awareness of some of the issues pertaining to light pollution, Loch Ness Productions in collaboration with the International #DarkSky Association has created a 6.5-minute 'public service announcement' called Losing the Dark. It introduces and illustrates some of the issues regarding #LightPollution, and suggests three simple actions people can take to help mitigate it.
"Losing the Dark was initially created in fulldome video format for digital planetarium use. It also has been made as a conventional flat screen video, for use in classrooms, kiosks, museum theaters, and advocate multimedia presentations. Classic #planetarium theaters without fulldome capability can show this version using their traditional video projectors."

"A proposed #NewYorkState #law aimed at reducing #lightpollution could create a real problem for the state’s millions of #Jews, particularly on #Shabbos and #YomTov.
The “#DarkSkiesProtectionAct,” introduced in the State Senate by #Senator #BradHoylmanSigal, would require most outdoor lights across #NewYork to shut off between 11 pm and sunrise starting January 1, 2028.
The #legislation covers residential floodlights, building uplighting, commercial spotlights, and billboards, with the goal of preserving dark skies while “promoting safety for people, birds and other wildlife, conserving energy and reducing our carbon footprint.”

SQUEE! #TransformingNight from @[email protected] comes out three months from today*! #ArtificialLight #ALAN #LightPollution #Night #Darkness #LightJustice uwapress.uw.edu/book/9780295... *As a former French historian, release date on Bastille Day cracks me up
Transforming Night -
It’s International Dark Sky Week (April 13-20, 2026), an annual event held each April during the week of the new moon to celebrate the wonder and importance of the night and raise awareness about the harmful effects of #LightPollution
From the darkness that supports critical wildlife ecosystems to the star-filled skies we enjoy, the night is filled with wonder and importance.
This year’s theme invites people to discover the night by making an active choice: to “go dark” and experience natural darkness firsthand.

As a historian (of #night #ArtificialLight #ALAN #lightpollution), this is a fascinating study for so many reasons. And conveniently it is now in the conclusion of my Memphis talk for next week.
