Tracking the Health of Earth’s Ecosystems with New Global Productivity Data Gross primary productivity (GPP) is a key indicator of ecosystem health. New data from Land & Carbon Lab provides the first global, higher resolution GPP data.

The global bimonthly 30m GPP product (2000-2024) is now ready for use (landcarbonlab.org/insights/glo...); available on GEE, STAC... so proud of the @opengeohub.bsky.social and @worldresources.bsky.social & colleagues!

North America’s forests used to burn a lot more than present… So, is climate change really making wildfires worse today?

A good story about current and historical fire activity in Canada (and the US) though I may be biased
