Lichens Are Beautiful! There are two examples of lichen in the much younger Oligocene Baltic amber. The oldest fossil lichen is about 400 million years old (Devonian) from the Rynie Chert in Scotland. (Source: UCMP + refs therein). Lichens are probably even older! #FossilFriday #Fungi 🧪🌎🦖

Hooray for a conservation win! #Reef #SixthExtinction #Conservation🧪🌎

Extinction isn’t random. Range size matters. Temperature tolerance matters. Climate change matters. But there’s another piece we’ve long suspected: geography. For 500 million years, the shape of continents helped shape survival. 🧪 #SciComm buff.ly/rPvvUEM

HAPPY 5-(🌎)YR LANDIVERSARY to our Perseverance Rover 🍰 As a Jezero mapper, seeing the *image* from SkyCrane of M2020 being lowered to the crater surface, will forever be a highlight of my career. CONGRATS to the entire M2020 Team (extra special shoutout to the EDL engineers!) 🧪🔭 #PlanetarySci

science is alive on bluesky, the official app of science 🧪

The Trump Admin's repeal of the Endangerment Finding is brazen denial of climate science that puts polluters before people. We will continue to fight this in every way we can.

If all Earth’s ice sheets melted, sea level would rise ~65m over millennia But just 1–2% of that (~65–130 cm) would force chronic flooding & retreat in many coastal cities ~1 billion people live within 10m of sea level (~15% of total) The risk isn’t the end state, it’s how little change it takes!

The irony of ICE expanding and polar ice contracting is not lost on me. Naked fascism in an effort to control climate-driven migration in the US just wasn’t what I expected.

I just think this is cool: the re-colonization by marine life at the site of the Gardnos meteor crater - except this is Neoproterozoic in age, before complex life. #PaleoSky #Geology 🧪🦕🦖⚒️ From "P3": www.sciencedirect.com/science/arti...

Anthropogenically-accelerated climate change is ultimately leading to a warmer Earth faster than is natural, but the process is one of chaos and instability, like our recent deep-freeze and snowfall in the U.S. and Canada. #ClimateChange🧪🌎

#FossilFriday for all of us paleontologists, because this is something we all have faced in some form or another:

In this week's episode of @cleaninguppod.bsky.social, Bryony sat down with US-based climate scientist @hausfath.bsky.social for an update on all things climate science. Zeke is extremely grounded, no exaggerations and fake scenarios. But oh, the comments already! www.youtube.com/watch?v=EzyS...

From Nature: “global greenhouse-gas emissions could be cut by 20% by 2050 by eating healthily, reducing food waste and adopting sustainable production practices”, writes Rockström. “If diets remain unchanged, however, emissions will increase by 33%.” #ClimateChange 🧪🌎 www.nature.com/articles/d41...

The forests of the Amazon and Andes are changing: warmer, dryer places are losing diversity; possible climate refugia gain diversity; and the overall transitions across the forest are complex. #Conservation #ClimateChange #SixthExtinction 🧪🌎🦤

Wolverines were once a staple among Colorado’s high peaks. For more than a century, their absence has left ecosystems devoid of a native carnivore and Coloradans bereft of a long-sought wildlife recovery story. That void could soon be filled with paw prints if state leaders have their way. 🌎

The Royal Ontario Museum added thousands of objects to their only museum catalogue last year—which now totals almost 90,000 objects. My favorite remains this late antique child’s sock from Roman Egypt. 🧦 collections.rom.on.ca/objects/3736... The ancient world was full of kids and color.

How cool is this? A sock from Roman Egypt that looks like it could have come from my abandoned sock drawer! Wow!

In addition to what these Comments discussed, there's the issue of lag time and effect: the effects of what we put into the atmosphere today will be felt in the future, not this year or next. #ClimateChange 🧪🌎 Two Comments in Nature: www.nature.com/articles/d41... www.nature.com/articles/d41...

"Insects are undergoing concerning declines across the world, and...essential ecosystem services will increasingly be at risk” "While invasive species are considered a nuisance, the study suggests they are still a manageable threat" We still have time to fix it. #ClimateChange #Conservation 🧪🌎 🦤

"Geologists have now installed a pair of ultrasensitive seismometers 2.5 kilometers beneath the South Pole...the instruments should be able to detect every earthquake over magnitude five, as well as the slight tugging on Earth from the Moon and other planets." 🧪⚒️ #Geology
