Card #20: Disruption of the Water Cycle

En-en adult card 20 front.png

Hotter oceans and a hotter atmosphere lead to stronger evaporation, causing rainclouds and rainfall. Hotter land and a hotter atmosphere also lead to stronger evaporation, this time causing the ground to dry out.

Explanation

This card is important. It alone shows why we used to talk about global warming and now about climate change.

Temperature increase is in itself a problem, but you can see on the Fresk at the end that disruption of the water cycle has much more effect.

Facilitation advice

To illustrate that evaporation takes place at the surface of the water, place cards 17 and 21 on the table, place the lower edge of card 21 against the upper edge of card 17, then place card 20 at the boundary of the two, perpendicularly, to mark the surface of the water (between water and air).

  • Melting ice sheets It's a bit technical, but the blue part of the map of Antarctica on card 19 represents a gain in mass due to an increase of precipitations. The red part represents a loss in mass. In total, Antarctica is losing mass.
  • Vectors of disease The Vectors of disease card is generally linked to the Terrestrial Biodiversity card because disease vectors are a sub-part of biodiversity, but it can also be linked to the same causes as the biodiversity card, i.e. Disruption of the Water Cycle and Rising Air Temperatures.
