Chilling Truth: Earth System Models’ Blind Spot on Permafrost Emissions

A commentary in Nature Climate Change raises concerns about how science financing affects Earth System Models, particularly in modeling permafrost emissions for environment predictions. Credit: SciTechDaily.comFunding obstacles and complexity have kept permafrost processes out of models that inform worldwide climate targets.The method science is funded is hindering Earth System Models and might be skewing essential climate predictions, according to a new comment published today (January 18) in Nature Climate Change by Woodwell Climate Research Center and a worldwide team of design experts.Permafrost Emissions and Modeling ChallengesEmissions from defrosting permafrost, frozen ground in the North that includes two times as much carbon as the environment does and is thawing due to human-caused climate warming, are one of the largest uncertainties in future climate forecasts. Precise representation of permafrost characteristics is missing from the major models that predict future carbon emissions.Only 2 of the eleven Earth System Models (ESMs) used in the last Intergovernmental Panel on Climate Change (IPCC) report consist of permafrost carbon biking at all, and those that do currently utilize over-simplified approximations that do not record the totally vibrant ways that permafrost carbon can be launched into the atmosphere as the environment warms.
