Hello #FediScience, migrating from astrodon.social (about to close), I am joining you here (inspired by @wolfgangcramer), so it's time for a new #Introduction

I'm Alexandre Santerne (call me Alex), #astronomer working @LAM_Marseille & teaching at Aix-Marseille #University (France).

I'm expert in finding #NoPlanetB 😀 ( #planets around other #stars).

I want to work in a #fair, #inclusive, and #sustainable #research #environment, so I (try to) act accordingly. I'm a member of @labos1point5

I toot a lot about #Astronomy, #Astrophysics, #Space but also a lot about #ClimateChange and #Climate.

Since 2019, I completely boycott planes, and I travel by #train (long distance) and #bike (short distance) as much as I can.

My other interests include #photography (visit my Flickr gallery in my profile) #Astronomy#Space

Oh, in case you don't know where Aix-Marseille is (trick: in 🇫🇷 ), the image below (credit: #NASA / JPL-Caltech / Space Science Institute) is indicating where I am, as seen from #Saturn...

... and where you also are, together with 8B people as part of 2M species 😀

This rare image taken on July 19, 2013, by NASA's Cassini spacecraft has shows Saturn's rings and our planet Earth and its moon in the same frame. At the time, Cassini was 2013 from a distance of about 898.414 million miles (1.445858 billion kilometers) from Earth. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself) taken by Cassini's wide-angle camera.

#ClimateChange and #energy

We did the math on #AI’s energy footprint. Here’s the story you haven’t heard.
The #emissions from individual AI text, image, and video queries seem small—until you add up what the industry isn’t tracking and consider where it’s heading next.
The latest reports show that 4.4% of all the energy in the #US now goes toward #datacenters. The #carbon intensity of #electricity used by data centers was 48% higher than the US average.

This is intriguing. Climate activists vs. indigenous police;

https://www.theguardian.com/culture/2023/aug/28/burning-man-protest-climate-change-environment

In general, I support disruptive climate protesting, and I get why Burning Man is a juicy target, likely to get them lots of news media coverage. But the protestors clearly didn't engage with the indigenous people whose land they were protesting on, which the Burning Man organisers presumably do. There's no unambiguous "right" side here.

#introduction
Hello, I'm completely new to Mastodon. I'm a scientist, so I thought a server about scientific communication would be interesting. I'm a plant physiologist, more specifically a forest tree ecophysiologist, working on how trees acclimate to #DroughtStress, and generally interested in the effect of #ClimateChange on #Forests . Posts can be in English, German or French.
