Rapid Arctic environmental change affects the entire Earth system as thawing permafrost ecosystems release greenhouse gases to the atmosphere. Understanding how much permafrost carbon will be released, over what time frame, and what the relative emissions of carbon dioxide and methane will be is key for understanding the impact on global climate. In addition, the response of vegetation in a ...

May 17, 2021 · The permafrost region contains a massive frozen store of ancient organic carbon (), totaling approximately twice the amount of carbon as is in Earth’s atmosphere.This carbon accumulated over tens of thousands of years when cold and frozen conditions protected the carbon-rich organic material (derived from dead plants and animals) from microbial decomposition.
Nature 572, 520–523 (2019). Natali et al. Permafrost carbon feedbacks threaten global climate goals. need for integration of scientific understanding within policy-relevant frameworks. This includes increased scientific focus on understanding the impacts of 1.5 °C versus 2 °C, or even greater, warming; the changing feasibility of these ...

Permafrost sensitively reacts to climatic changes and is defined as one of the Essential Climate Variables (ECVs) by the Global Climate Observation System (GCOS) of the World Meteorological Organization (WMO). The three products associated to the ECV «Permafrost» to observe its evolution are (Streletskiy et al. 2021): i) permafrost temperature,
