Why are socialists all over the world so focused on an election in New York?

For the same reason the US spent the 20th century toppling democratically elected socialist leaders.

Because ours is an internationalist movement - a victory for one is a victory for all ✊

Seria muito bom conversarmos com representantes no comitê assessor de CNPq, para que @ojastro.bsky.social seja considerada em avaliações apesar de ainda não ter fator de impacto.

Comunidade brasileira de Astronomia e Astrofísica, @sabastronomia.bsky.social , têm considerado publicar nessa revista ja que #ApJ, #A&A e #MNRAS com seu "open access" dificultam que publiquemos nelas?

At the equinox of 20 March 2025, our planet is neither tilted towards nor away from the Sun, creating nearly equal day/night. This stunning Meteosat-12 image taken earlier this morning showcases the boundary between day and night running straight through the poles.

🌍 Happy #Equinox! On 20 March 2025 at 09:01 GMT/10:01 CET, just a few moments ago, the Sun appeared directly above Earth's equator - with our planet neither tilting towards nor away from the Sun!

High magnification view of the moon's terminator during the waning gibbous phase using a telescope. It's a gray-scale image showing many craters and a relatively flat region near the center known as mare nectaris.

Mare Nectaris is the result of a large impact on the Moon early in its history, around 3850 million years ago. You can see the border of the crater as an irregularly shaped wall. I took this image yesterday from my backyard. This is the Moon's waning gibbous phase. 🧪 🔭

physics of climate impacts 101:
- Stuff gets hot (worse heatwaves)
- Hot air holds more water vapor (heavier rainfall)
- Hot air is thirstier air (higher drought risk)
- Warm water is hurricane food (stronger storms)
- Hot water expands and hot ice melts (sea level rise)

This is not unexpected, yet extremely sad.

YouTube video by D'Angelo okay literally just delete twitter at this point

Um teste simples: criar um novo perfil no Twitter, não seguir ninguém e curtir música, arte e games.

O que é sugerido? Extrema direita e o dono da plataforma. Continuamente. Mesmo depois de bloquear.

É aqui a bolha?

Muito bem apontado, parafraseando livremente: se acreditamos na ciência das mudanças climáticas, mas nos comportamos como se o mundo de amanhã vai ser o mesmo de hoje, nós somos os negacionistas!
