NASA Scientific Visualization Studio | Global Views of ICESat-2 Data ICESat-2 data products on a rotating Earth. Together they illustrate the satellite’s measurements of Earth’s land, ice, oceans, forests, and atmosphere.

This breathtaking visualisation from @thenasaearth.bsky.social's shows how the ICESat-2 laser altimeter has provided us with a staggering amount of geodetic information for Earth allowing us to track vital signs svs.gsfc.nasa.gov/5616

Ask a Scientist: How Do the Polar Regions Impact You? For the past three decades, glaciologist Helen Amanda Fricker has been investigating polar regions — the fastest changing areas on Earth. By studying the Arctic and Antarctic, she and other scientists...

Scripps Oceanography glaciologist @helen-amanda.bsky.social studies the fastest-changing places on Earth to understand how melting ice and rising seas impact communities everywhere. We caught up with the celebrated scientist to learn more about her work and why it matters now more than ever. ⤵️

Include individual US states in the world’s biggest economies & it’s impressive that Ireland ranks 38th. To go from one of the poorest in Europe in 50y is impressive*. There are only 5.2m on the island which explains Ireland being one of the richest countries per capita in the world.

This is truly joyful!

Trump's EPA kills the endangerment finding—the legal basis for nearly every major US climate regulation Legal experts say that regulating carbon dioxide is well-supported by the text of the Clean Air Act—a fact that even the conservative Supreme Court has recognized in multiple cases, suggesting the…

"President Donald Trump's approach to climate change rests on one key premise: Greenhouse gases are not that bad.

This is a simple argument—albeit one that flies in the face of the scientific consensus on climate change—but it could have profound consequences," writes Jake Bittle.

More pollution and higher energy costs: critics condemn Trump’s anti-environment agenda US courts, scholars and Democrats are pushing back against the president’s aggressive drive to boost fossil fuels

Just in case it wasn't obvious that Trump's energy policies make no sense, except for his cronies:

NASA greenlights two earth science missions, to researchers’ relief Orbiting satellites will monitor changes in the stratosphere and on the planet’s surface

Researchers "overjoyed" #NASA is going to move forward with two new $355 million Earth science satellites. One watching stratosphere, one watching ice/forests.🧪 My latest for @science.org:

He needs to read the room. Or the stadium. Or the country. Or the world.

A Climate ‘Shock’ Is Eroding Some Home Values. New Data Shows How Much. Changes in the insurance market have started to affect home prices in the most disaster-prone areas, new research finds, pushing some homeowners’ finances to the breaking point.

This risk—now this reality— was clearly foreseen 20 years ago when in first started working on climate change, and warnings were given— but no one wanted to hear them and some fought to belittle the Cassandras. So many Americans are now trapped in a terrible position as a result.

🛰️BIG NEWS! NASA has selected a
@ucsandiego.bsky.social led satellite mission for the Earth System Explorers program. Led by Scripps Oceanography glaciologist @helen-amanda.bsky.social, Earth Dynamics Geodetic Explorer (EDGE) is one of two next-generation satellite missions selected. 🧵⤵️

NASA Selects Two Earth System Explorers Missions - NASA These two missions were selected for continued development as part of NASA’s Earth System Explorers Program, which conducts principal investigator-led Earth

Significant news out of NASA earth science: They've finally selected two new missions for its explorers competed line, cost capped at $335M: EDGE, a next-gen lidar and successor to Icesat-2/GEDI, and STRIVE, a limb sounder for pollution and more and much-needed successor to Aura.

Here, we chart the five big themes for US science in 2026:

- The budget showdown
- Battle over 'indirect' or administrative costs
- Political appointees gain power, deprioritizing scientific merit
- University reforms
- International student decline

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

January 24, 2026 This morning, on a street in Minneapolis, at least seven federal agents tackled and then shot and killed Alex Jeffrey Pretti, a 37-year-old ICU nurse for the local VA hospital.

(iii) The Titanic is a ship that sank because it collided with an iceberg that calved from Greenland. The Titanic was not turned around.

(i) Greenland is not a piece of ice; it is one of Earth's two ice sheets. The other one is Antarctica. Ice sheets gain mass through snowfall and lose it again via iceberg calving and basal melting.

(ii) Iceland is not Greenland. 2/3

Glaciologist jumping in to use the bizarrely misinformed statements of the past 2 days to inform about ice sheets.

Will cover three things: (i) Greenland, (ii) Iceland and (iii) the Titanic, and how they relate and don't relate. 1/3

My First 72 Hours in Minneapolis and How I Got an ICE Agent to Scream “MAKE AMERICA GREAT AGAIN” The activists on the ground are doing the work, that should give you hope.

"Here are the demands we all need to make: Use the National Guard to protect our citizens. Arrest agents who commit crimes. Charge police, National Guard, and ICE with crimes when they commit or refuse to stop them. . . . Do it now."

Thank you @hiltonhonors.bsky.social

I'm at a local gym and a Kristi Noem ad about Trump's immigration policies came over the radio. I went to tell the front desk and they looked alarmed and said they would take care of it and change stations straight away. Speak up when you hear that crap.
