Satellites reveal tropical wetland flooding did not cause methane surge
Human activity or other wetland factors like temperature or soil chemistry could be at play.

Vital research data is disappearing in front of our eyes! ⚠️ Right now, NOAA is being blocked from using satellite data to monitor sea ice loss. 😖
Not knowing how the Arctic is changing will not diminish its impact on our climate, it just makes us more vulnerable to the consequences.
