Sentinel-6B launched to extend record of sea-level rise [link]
"The Copernicus Sentinel-6B satellite is now circling Earth, ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change.
Like its predecessor, Sentinel-6 Michael Freilich, Sentinel-6B carries the latest radar altimetry technology to further extend the sea-surface height record that began in the early 1990s. These measurements help scientists understand sea-level rise – crucial information for shaping climate policy and protecting the millions of people living in coastal areas around the world."

Snapshots
Iraq Reservoirs Plunge to Low Levels [link]
"Satellite observations of Lake Tharthar show that the reservoir’s water levels have swung sharply during the past three decades.
The lake, Iraq’s largest, lies within a broad natural depression between the Tigris and Euphrates rivers, although its water comes only from the Tigris. During periods of excess flow, water managers divert floodwater from the river at the Samarra barrage via a canal and into the reservoir. These inflows usually cause water levels to spike in the spring, when snowmelt in the headwaters of the Tigris in Türkiye and Iran joins with runoff from seasonal rains.
However, a lack of snow and rain, along with upstream diversions, have starved the reservoir of inflow in recent years, preventing water levels from rising in 2021, 2022, and 2023. Despite a slight improvement in 2024, plunging water levels have accompanied the multi-year drought."

ESA investigates high-stakes Amazon tipping point [link]
"For decades, the Amazon rainforest has quietly absorbed vast quantities of human-generated carbon dioxide, helping to slow the pace of climate change. Recent evidence, however, suggests that this vital natural buffer may be weakening – though uncertainties remain.
To help close this critical knowledge gap, European and Brazilian researchers have gathered deep in the Amazon to carry out an ambitious European Space Agency-funded field campaign."
Podcasts
Join Matt Forrest, Chris, and Isaac as they cut through the noise of geospatial AI to explore whether foundation models are truly ready for deployment, or if the field is still navigating a “wild wild west” of unproven tools and hype.
This discussion challenges the industry’s obsession with foundation models, arguing that “scale is a trap” and that solving fundamental data infrastructure bottlenecks often creates more value than complex deep learning.
Ultimately, the conversation suggests that the best way to cut through the noise is to simply “go touch some data” and focus on solving specific, real-world problems with grounded methods.
