The ocean floor off Washington, Oregon and California is riddled with deep-sea vents that spew the greenhouse gas methane.
The discovery was made by researchers on the Ocean Exploration Trust’s submersible ship Nautilus. The organization told the National Ocean Exploration Forum in New York that it expects to find other ocean seeps elsewhere.
Methane traps atmospheric heat 40 times more efficiently than carbon dioxide.
A startup company has launched a fleet of tiny earth-observing satellites designed to photograph every part of the world every day to help reveal how the planet is changing.
The company, Planet, has so far put 133 of the satellites in orbit, and says they can be calibrated to observe every single tree on the planet to allow unprecedented visual evidence of deforestation no matter where it occurs.
Planet is currently sharing its data with groups such as Amnesty International, the Monitoring of the Andean Amazon Project and the U.S. government’s National Geospatial-Intelligence Agency.
