== Explanation ==
The two last cards to be added to the Fresk after card 40 are potentially violent 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 (CH<sub>4</sub> -- in the oxygen-deprived bottom).

[[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 [[En-en adult card 41 permafrost|permafrost]] and methane hydrates back to the energy budget.
