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.

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.

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.

Fact Point @factpoint.bsky.social · 27/05/2025
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.
