Weakening Gulf Stream

Weakening Gulf Stream

Weakening of thermohaline circulation may disrupt water cycle even more in many places in the word.

1
Other possible cause

Deforestation

Deforestation

Deforestation can perturb local precipitation.

2
Other possible consequences

Melting Ice Sheets

Disruption of the Water Cycle

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

Disruption of the Water Cycle

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.

Wrong cause

Melting Sea Ice

Melting 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 beware, the "Water Cycle" card does not refer at all to the thermohaline circulation.

Wrong consequence

Rising Sea Levels

Disruption of the Water Cycle

No, more rain is not going to cause the oceans to overflow! This is a rare mistake to be made, but if it happens to you, ask the players where rainclouds come from...
