My book #TransformingNight argues that excessive focus on #LightPollution #ArtificialLight during clear-sky conditions until recently is a legacy of astronomy's early attn to issue.
IOW, even recent scientific assumptions and practices have been shaped by the past.

Insightful paper about distance to cities and cloud composition for the distribution and reflection of light pollution. These kind of measurements should become standard for monitoring, eg, of urban lighting impacts particularly on biodiversity beyond the urban environment.

I went to try and see the comet, and all I got was this blurry picture of maybe the Milky Way and a couple of tiny meteors. #iPhonePhotography #Stars #NightSky #LightPollution #meteors #GoOutside #Breathe #Notice
An iPhone photo of the star-studded night sky directly overhead: the south at the bottom, north at the top (roughly). It’s hard to find a place with minimal light pollution, and as hard as we tried, we couldn’t see the comet (definitely not in this picture). The phone may have managed to capture a hint of the Milky Way - a vague, cloudy strip stretching from top to bottom in the center of the picture. Two of the “stars” are tiny streaks - not stationary dots of light against the black. One in the center left, the other down lower. Those may be related to the meteor shower going on.

PLZ TURN ur LIGHTS OFF during THIS SEASON

The night of October 4, 2023, hundreds of migrating birds slammed into McCormick Place, a large building in one of the major migratory fly-ways that’s floor-to-ceiling glass.

As hundreds of millions of birds head south, the invisible danger is glass — NPR
It’s the peak of the fall migration season. This is when bird deaths from window collisions tend to spike, even though simple solutions can prevent this.

As #UHA2025LA kicks off, I’m happy to share here my most recent piece on the Metropole, on an understudied topic in #urbanhistory #envhist —how different lighting tech’s have affected birds & humans over the centuries & what we can do about it.

It’s a dual exposé & call to action Check it out here:
urbanhistorya.bsky.social Urban History Association (the official account) @urbanhistorya.bsky.social · Oct 9
"Urban historians have written much about technological and social change in cities and very little about the ways in which historical transformations in lighting technologies have affected environments and ecologies, and the habitats and health of birds." from @charlotte-leib.bsky.social

Cities light up the sky & that confuses birds. They fly toward the glow, circle in disoriented loops, & crash into glass buildings.
It’s estimated that up to 1 billion birds die this way every year across the U.S.
Night lights for safety…yes
The rest…#LightsOut

4. It's up to all of us, in this time of #biodiversityloss #climatechange & corporate governance to embrace the fact that #lightpollution is one thing we—as individuals and communities—can control.

So shield those streetlamps, choose warmer hued bulbs & #turnoffthelights! The #birds will thank you.
A diagram of different urban lighting scenarios set against a dark blue-black backdrop and starry night (represented in abstract illustrated form). First, at left, (1) Problematic urban lighting. A giant light orb casts out from a streetlamp, blinding and white, extending into much of the night sky. Next (2) A streetlamp represented with a temporal controller installed. The streetlamp stands dimmed and darkened. No stray light sheds into the night sky. Third (3) A downshielded and dimmed streetlamp. Here, the light, still a white hue, is directed to the ground and there is no upward or outward pollution. Fourth (4) A streetlamp that uses a warmed temperature bulb. Its light appears in an oranger-pinker hue. The diagram notes that the light temperature for this color must be <3000 Kelvin.

A bright city at night. A quote from Prof Euan Ritchie says: “Smart lighting regulation is a win-win. It helps protect wildlife, cuts energy use, improves human health, and restores the wonder of a starry night sky." Sydney harbour without light pollution, showing the milky way galaxy. A quote from Prof Theresa Jones says: “Communities are passionate, and even lighting engineers are advocating for change. It’s time to put lights only where they are needed, into places where they are needed and for as long as they are needed.” A pastel pink moth sitting on white cloth. A quote from Dr Jess Marsh says: “Light pollution is a trap for night flying insects like moths, disrupting movement patterns, life cycles and exposing them to predators. Light pollution regulation helps free them from this threat, ensuring these small but important creatures can continue their important functions in the ecosystem.” There are two quotes. The first from Dr Kaori Yokochi says: “Microbats help maintain ecosystem health by keeping insect populations in check, but artificial light reduces bat diversity and activity. Light pollution regulation will help these tiny superheroes thrive in our cities.” The second quote from Prof Nicki Mitchell says: “A baby sea turtle entering the water for its first swim is awe-inspiring. It’s less good to find them wandering through coastal car parks. Keeping hatchlings in the dark is key to giving them the best start in life.”

Seaweed-associated microbial communities show limited responses to light pollution and warming 🌱💡

New paper assessing the independent and combined effects of #lightpollution and #oceanwarming on microbial communities associated with two habitat-forming #seaweed species 🧪🌐🌊

Graphical abstract showing two plots illustrating distance to centroid (degree of dispersion), with the left plot showing values for Ecklonia radiata (picture of Ecklonia below, with symbol showing microbes) and right plot showing values for Sargassum (picture of Sargassum below, with symbol showing microbes). The Ecklonia plot shows greater dispersion with warming, while the sargassum plot shows no effect of treatment.

Leseprobe aus meinem neuen Buch #1 ✨
Vor einem Abendhimmel mit dramatischer Wolkenstimmung und schwarzen Baumsilhoutten ein Textfeld in schwarz. Darauf in weißer Schrift: ndem wir die Dunkelheit wieder als Schutzraum begreifen, als Teil unserer Welt und nicht als etwas zu Vermeidendes, könnten wir lernen, einen anderen Umgang mit der Nacht zu entwickeln. Sie als Möglichkeitsraum erleben, in dem wir durchatmen und den Nachthimmel betrachten können, um uns wieder als Teil eines größeren, unergründlichen Universums zu spüren. Sie könnte zu einem Ort werden, der uns nicht abschreckt, sondern uns auffängt. Der uns Kraft schenkt, eben doch noch zu kämpfen, gegen die Ausbeutung unsere Nächte, Natur und Körper. Ich wünsche mir, immer noch, dass alles wieder gut werden kann. Aber Hoffnung reicht dafür nicht aus. Also wünsche ich mir stattdessen, dass wir Kraft haben, dass wir ein Kollektiv sein, eine lebenswerte Welt einfordern können. Und zwar für alle.
