Leonid Yurganov is a scientist who measures the methane emissions all around the world with spectrometry from satellites. He has twenty years' data on the subject by now. Peter Wadhams specializes in the study of sea ice and the methane being released in the Arctic. Yurganov shows some maps of the north pole area taken from his instruments at different times. Much more methane is being emitted lately than previously, and much more in the winter than the summer. We are worrying a lot now about the potential for bursts of methane from the sea. However, there is more methane being emitted gradually from permafrost on land. For the video, audio podcast, transcript and comments: https://tosavetheworld.ca/episode-507-arctic-methane.
