The tiny particles from wildfires can lodge in the lungs or make their way to the bloodstream. Years of repeated exposure to wildfire smoke can increase chances of a premature death. www.sciencenews.org/article/what...

Happy Fourth of July chipmunk.

What *actually* works — right here, right now — to address climate change? Here you go. This is the result of thousands of hours of painstaking research and analysis from the Project Drawdown team.

Two selfies with the Roman Space Telescope after she turned her mirror towards us today. To see the second you'll need to zoom in, my image is tiny and upside down.

The Artemis II images browser is in a much better shape now, with separate collections for the Earth, Moon, and Eclipse images. A complete scientific data archive prepared by the lunar science team and peer-reviewed is to be released through NASA's PDS. eol.jsc.nasa.gov/Collections/... #Artemis 🧪🔭

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

Why do I have to pretend that I'm going to print something in order to save it as a PDF. Why do I have to engage in a little ruse.

🆕 Several Earth system components may be closer to destabilisation than previously thought. Crossing key temperature thresholds could trigger feedback loops, pushing the planet toward a “Hothouse Earth” trajectory.

🛰️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. 🧵⤵️

Don was visionary leader of SDSS and a wonderful mentor to many postdocs and students at U Chicago, myself included.

Here is the 2025 version of our annual visualization of global temperatures from GISTEMP. NASA's estimate has 2025 tying 2023 for the second warmest year since 1880 (2024 was the warmest). svs.gsfc.nasa.gov/5603

In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

SVS is such a valuable NASA group!!

The New York Times article about the Escapade missions includes a beautiful visualization by the SVS's AJ Christensen. www.nytimes.com/2025/11/14/s...

Coffee prices are skyrocketing and Rise Up Coffee isn't taking any chances.

Now that the Sept and Oct data are (belatedly) in, it looks like 2025 will be the second warmest year in the record (~80% probability). The last three years are in a class of their own.

#30DayMapChallenge | Day 2: Lines (Miniature Globes Edition) For today’s theme, “Lines,” I created a miniature globe of NASA SVS’ Global Sea Surface Currents and Temperature visualization. Look closely to see the mesmerizing ocean eddies!

NASA is more than rockets and moonwalks. NASA is behind much of our everyday technology. From space discovery, to Air Jordans, to CAT scans, NASA has played a role. We get it all on less than a penny of every federal dollar. Now their science may be gutted by 50%. #NASADidThat

A few tips: 1: Open up your aperture as much as you can for more bokeh. Faster lenses are better. 2: Make a mark on your focus ring + lens (I use two narrow strips of masking tape) so you can quickly and repeatedly hit your in-focus point.

“I personally was pretty surprised, actually, at how efficient the government was,” Sahil Lavingia told NPR's Juana Summers.

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

The core portion of the Nancy Grace Roman Space Telescope has successfully completed vibration testing, ensuring it will withstand the extreme shaking experienced during launch: go.nasa.gov/4jNWjcK 🔭 🧪

Last day at the GISS building (Wed. May 28th). 🥲

In a super interesting new paper we show how ENSO and other climate oscillations influence crop yield variability today and in the future. Check it out! www.sciencedirect.com/science/arti...

Upsetting news today about the lease on the GISS building being cancelled. Solidarity with my GISS colleagues who do important work on food security, agriculture, exoplanets, and education in addition to their groundbreaking climate modelling.

Museum and Planetarium Friends, Many of you use NASA SVS material. Right now it is critical that we are able to document SVS's impact. Please let us know how you are using our content (use my email address at the bottom of this page: svs.gsfc.nasa.gov). Thank you!

Phew that was close! www.nbcwashington.com/news/local/g...

🧪🌊 Despite the political chaos, Earth warms & seas rise. Satellite data show global #sealevel rising since 1993: higher than expected in 2024 (0.59 cm/yr vs. 0.43 cm/yr predicted), mostly due to excess ocean thermal expansion. The ocean are complicated. See NASA/JPL report in ALT text & below 1/2
