Satellites Reveal Tropical Wetland Flooding Did Not Cause Methane Surge

A recent study from the University of Michigan is challenging the idea that the big jump in methane levels between 2020 and 2022 was mostly caused by tropical wetlands. Scientists used satellite images to see if rising water levels in these areas matched up with the increase in methane. Their findings suggest there may be other reasons behind the rise. Read on to learn what they discovered—and why this matters for understanding climate change.
