I’m delighted to share that our new paper is now out in @natclimate.nature.com! Our long-term, monthly Antarctic-wide dataset of surface meltwater shows that the East Antarctic Ice Sheet is becoming increasingly prone to surface meltwater ponding.

Continent-wide mapping shows increasing sensitivity of East Antarctica to meltwater ponding - Nature Climate Change

This study provides a continent-wide assessment of surface meltwater area in Antarctica between 2006 and 2021, highlighting recent increases in magnitude and variability in East Antarctica, with indic...

One of the most surprising (and exciting!) things about first getting into Carto/GIS work was discovering how accessible* NOAA, NWS, Landsat, Sentinel, etc. were. Like yeah you had to find and learn how to process them, but all this data, yours to discover and use.

WHY WE LOOK? Because the final image captured by the recently decommissioned Landsat 7 satellite shows how Las Vegas, "Sin City," has nearly doubled in size during the iconic spacecraft's 25-year lifespan. www.livescience.com/planet-earth...

Remembering its quarter-century of faithful Earth observation, the USGS and NASA have announced the decommissioning of Landsat 7 from active service. Landsat 8 and Landsat 9 continue to collect images every day. Read more about Landsat 7: ow.ly/nz9k50W5CAQ

#Landsat 8 collected new images of these Canada fires on June 5, 2025. Image A shows a wildfire near the Petitot River in northeastern British Columbia. The Saskatchewan fire in image B is burning east of Mari Lake. More than 200 fires are currently active across Canada.

🌎🛰️After 25 years of Earth observation, the USGS bid farewell to #Landsat 7 on June 4, 2025. The legacy continues with Landsat 8 and 9, capturing planetary imagery to support global communities. 👉 ow.ly/ZTf150W4mp3

USGS, which operates the Landsat satellites, just announced that Landsat 7 was officially decommissioned today. Landsat 8 and 9 continue operations. www.usgs.gov/news/nationa...

End of an Era: Landsat 7 Decommissioned After 25 Years of Earth Observation

#Landsat 9 captured imagery of an area in southern Switzerland that was devastated by a landslide on May 28th caused by partial glacier collapse. These natural color panchromatic-sharpened images show the area on May 13th, and again on May 29th.

Dust storms contribute to the accumulation of PM2.5 and PM10—particulate air pollution that is associated with respiratory and cardiovascular health risks. They can also spread viruses and fungal diseases and drastically reduce visibility.

Dusty Skies in California Farm Country

Researchers found a relationship between idle farmland and dust storms in one of the nation’s largest breadbaskets.

Fallow farmland is the main source of human-caused dust storms in California’s Central Valley region, according to a new study using data from NASA and others. From 2008-2022, 88% of major human-caused dust events were associated with fallow land.

Volcán Poás, one of the most active in Costa Rica sustains a hot, ultra-acidic crater lake that shares similarities to Martian environments The Poás system may be hostile to most forms of life we are familiar with. But for a microbe adapted to acid, heat, and toxic metals, it’s paradise 🧪

This is near Vancouver Island in British Columbia, Canada. And see that blue glow? That’s a herring spawn! Every spring, thousands of Pacific herring congregate in shallow, vegetated coastal areas around this area to spawn, like in this #Landsat 8 image from April 27. (via NASA Earth)

Eruption of Kilauea as seen by Landsat-8/9 on May 16, 2025.

Scientists have discovered that trees near volcanoes can act as early warning systems before eruptions. As magma rises, it releases CO₂, which trees absorb—causing changes in leaf color and reflectance that satellites like NASA's Landsat 8 and ESA's Sentinel-2 can detect.
