Much of the Alaskan oil pipeline is anchored in permafrost soils. (realclimate.org)
Changes to the temperature and pressure of permafrost soils (and ocean waters) could lead to methane, a gas with a much stronger greenhouse warming potential than carbon dioxide, being released. (metlink.org)
The findings could change estimates of how much permafrost soil carbon — which constitutes about half the world's soil carbon in total — is transformed to greenhouse gases and released to the atmosphere. (scientificamerican.com)
