Gulp. One hoped that dangers predicted decades ago wouldn't happen. Release of methane stored for millennia in permafrost still is a major wildcard. Is it playing out with greater certainty now? Melting seabed permafrost releases considerable methane. Warming implications not fully examined.
Triple-isotopic analyses pinpoint microbial methane release from subsea permafrost in the inner Laptev Sea - Communications Earth & EnvironmentIn the inner Laptev Sea, observed methane releases dominantly stem from microbial methane pools within the subsea permafrost system, according to triple-isotopic analyses of dissolved methane and stat...www.nature.com
