Dr Lori Bruhwiler (NOAA), elaborates briefly on new methane estimates, with the focus on the Arctic (September 2016).
Methane emissions from fossil fuel development around the world are up to 60 percent greater than estimated by previous studies, according to new research led by scientists from NOAA and CIRES. The study found that fossil fuel activities contribute between 132 million and 165 million tons of the 623 million tons of methane emitted by all sources every year. That’s about 20 to 25 percent of total global methane emissions, and 20 to 60 percent more than previous studies estimated.
