-Permafrost is a soil that is permanently frozen for at least two consecutive years<ref>[https://www.ipcc.ch/site/assets/uploads/2018/03/WG1AR5_SummaryVolume_FINAL_FRENCH.pdf#page=212 Glossary, Report 5, Working Group 1 (French)]</ref>.

 The two last cards to be added to the Collage after card 40 are potentially violent [[wikipedia:Climate_change_feedback|feedback]] loops or "climate bombs" which, if triggered, would cause us to lose control over the climate for good.
-Thermokarst are veritable bioreactors at the heart of the process of releasing frozen carbon: when the permafrost thaws, pieces of soil detach and fall into the water, bringing nutrients and carbon to the bacteria and plankton present in the sea, which degrade them into CO<sub>2</sub> (in the water layers near the surface) and methane or CH<sub>4</sub> (in the oxygen-deprived bottom)<ref>[https://lejournal.cnrs.fr/articles/pergelisol-le-piege-climatique CNRS The newspaper Permafrost, the climate trap (French)]</ref>.

-For online murals, you can show this [https://youtu.be/YegdEOSQotE?t=82 video] from the University of Alaska Fairbanks showing the flammable methane stored in the permafrost.

-== Other possible links ==
+===Other causes===
+[[En-en adult card 14 energy budget|Energy budget]] If we take the idea of energy conservation all the way, we can link the thawing of permafrost and [[En-en adult card 42 methane hydrates|methane hydrates]] back to the energy budget.
-=== Other causes ===
+==To go further==
-[[En-en adult card 14 energy budget|Energy budget]] If we want to stay within the same logic of energy conservation, the thawing of the permafrost should be linked to the energy budget.
