Set 1 www.climatefresk.org 13 O efeito estufa é um fenômeno natural (a propósito, o GEE mais comum é o vapor de água). Sem o efeito estufa, o planeta seria 33 ° C mais frio e a vida como conhecemos não seria possível. Mas o CO 2 e outros GEE relacionados às atividades humanas amplificam o efeito estufa natural e desequilibram o clima.

The expression "Greenhouse Effect" is written on both sides (as of last version, October 2018).

Other possible cause

Permafrost

Permafrost

The permafrost card can be linked either to Other GHGs or to Additional Greenhouse Effect. The Other GHGs card is about GHGs emitted by human activities, while the methane in permafrost is not of human origin.

Wrong cause

Derretimento da banquisa / gelo marinho

Derretimento da banquisa / gelo marinho

This link would mark confusion with the amplifying effect due to albedo. The white sea ice melts to reveal a darker surface underneath and the extra energy absorbed warms the Earth. This mechanism is called albedo and has nothing to do with the greenhouse effect. It belongs to the orange arrows on card 13, not to the red arrows.
