A video that introduces permafrost and its distribution on Earth. The video also describes the changing nature of permafrost across several regions due to higher surface temperatures and thepossible impact of permafrost thawing on Earth’s climate.

Students will learn about the characteristics of permafrost, its distribution across the globe and how permafrost is used to study soil conditions for periods dating back to several thousands of years by extracting ice cores for analyses. They will also learn that the thawing of permafrost has led to the release of greenhouse gases such as methane to the atmosphere which can in turn, impact the Earth’s climate.
