===Causes===
 
* [[En-en_adult_card_15_radiative_forcing|Radiative forcing]]
This graph explains where the energy accumulated on Earth due to radiative forcing goes. It warms up the ocean, melts ice, dissipates into the ground and warms up the atmosphere.

* [[En-en_adult_card_17_increase_in_water_temperature|Increase in Water Temperature]]
* [[En-en_adult_card_18_melting_of_sea_ice|Melting of Sea Ice]]
* [[En-en_adult_card_19_melting_of_ice_sheets|Melting of Ice Sheets]]

If you choose to keep this card, you need to remember the first principle of thermodynamics: energy is conserved. Players may draw links from Energy budget to [[En-en adult card 17 increase in water temperature|Increase in Water Temperature]] and [[En-en adult card 21 temperature rise|Temperature Rise]], then links from [[En-en adult card 21 temperature rise|Temperature Rise]] to [[En-en adult card 16 melting of glaciers|Melting of glaciers]] and [[En-en adult card 17 increase in water temperature|Increase in Water Temperature]] to [[En-en adult card 18 melting of sea ice|Melting of Sea Ice]] and [[En-en adult card 19 melting of ice sheets|Melting of Ice Sheets]]. By doing this, they consider that the air and water warm up, and then they melt the pack ice, glaciers and ice caps. But if a calorie has passed through the water and finally contributes to melting the pack ice from below, then it is no longer in the water.

A tip to simplify the explanation of this card is to rename the following cards. An increase in temperature is an increase in energy, and melting is also an increase in energy. The five cards then become Increase in the energy level of water, air, sea ice... And the players will understand that these five cards have to be put at the same level. So if a calorie that is in the water contributes to melting the pack ice, once the pack ice has melted, this calorie is no longer in the water. The water has cooled down. In this case, should the calorie be counted in the "ocean" or "melting ice" part? Answer: in the melting part of the ice. You can't count this calorie twice.

[[En-en adult card 41 permafrost|Permafrost]] and [[En-en adult card 42 methane hydrates|Methane Hydrates]] If we want to stay within the same logic of energy conservation, we would have to make the melting link from the Energy budget.
 
* [[En-en adult card 41 permafrost|Permafrost]] If we take the idea of energy conservation all the way, we can link the energy budget to the thawing of permafrost.
