Card #20: Disruption Water Cycle
| Causes | Consequences | |
|
If the oceans and the atmosphere are hotter, the evaporation that takes place at the ocean surface increases.
This means more rain clouds and more rain. If this happens on land, then the soils dries 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 Collage 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).

Other possible links
Other causes
- Deforestation Vegetation retains water. When it is cut down, the risk of flooding increases.
Other consequences
- 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 Temperature Rise.
Wrong links
Wrong causes
Melting of Sea Ice The melting of the Arctic ice pack, but also the melting of Greenland's glaciers may lead, in the distant future, to a disruption of the thermohaline circulation (which gives rise to the Gulf Stream). But the "Water Cycle" card does not refer at all to the thermohaline circulation.
