This is the Irish language version of Permafrost from PolarStar.
Permafrost is permanently frozen ground that remains at 0°C or below for at least two consecutive years. It contains soil, rock and organic material, which has not decayed because it was frozen. Due to climate change, permafrost is thawing more and more, and when organic material unfreezes and decomposes it releases greenhouse gases into the atmosphere.
In this activity, students find out why thawing permafrost accelerates climate change and becomes dangerous for the Earth. They also do some calculations to compare potential carbon release from permafrost to anthropogenic production of carbon dioxide by their country.
This activity uses science to inspire students’ interest on how the world works. It contains multidisciplinary concepts like climate change, feedback loops, combines Physics, Chemistry and Geography. It also includes Mathematics, as the main task is to calculate the potential carbon release from permafrost compared to anthropogenic production of carbon dioxide.
The activity was created within the POLAR STAR project, co-funded by the Erasmus+ Programme of the European Union (2019-1-FI01-KA201-060780).
We would like to thank warmly Polar Advisors, who provided valuable ideas and materials for this particular activity: Stelios Anastassopoulos, Daniela Bunea, Svetla Mavrodieva, Spyros Meleetiadis, Nikolaos Nerantzis and Elena Vladescu.
