15 - Radiative Forcing
2Causes
Aerosols cool down the climate.
The expression "Greenhouse Effect" is written on both sides (as of last version, October 2018).
1Consequence
The text behind card n14 allows no ambiguity. Therefore the 2 cards have to be skipped together or not at all.
2Other possible causes
When the ice pack melts, a white surface is replaced by a dark blue surface, which has a lower albedo and therefore absorbs more energy. This relationship is not essential but it does allow another feedback loop of the game to be put forward.
