Protecting Permafrost: Addressing the climate threat of Arctic thaw

Protecting Permafrost: Addressing the Climate Threat of Arctic Thaw examines the significant climate threat posed by Arctic permafrost thaw. Climate heating is causing permafrost to thaw, leading to the release of heat-trapping gases like carbon dioxide and methane, which in turn accelerates climate change. The report assesses 13 potential interventions to slow or stop thaw and reduce emissions, with three being ready for deployment: wildfire management, caribou herding, and conservation or restoration of peatlands and wetlands. The report emphasizes the need for a comprehensive approach, including improving scientific understanding, gathering better data, developing permafrost thaw models, and creating governance frameworks. It recommends that the Canadian federal government establish a permafrost thaw mitigation task force to develop a national strategy, leveraging Canada's scientific capabilities and international collaborations to address this global challenge.
