Adaptation

(1) Policy Definition

Adaptation is the set of actions societies take to reduce the damage caused by climate change that is already unavoidable: since the climate will keep warming even if emissions stop, adaptation focuses on protecting people, infrastructure, food systems, and economies from impacts like heat waves, floods, and droughts. It does not reduce global warming itself (that is mitigation), but it lowers suffering and economic losses; however, if it is not planned early, adaptation is often forced by crises, becoming more costly, unequal, and destabilizing.

The efficiency of adaptation is unknown. This is why it is represented in CCEM by a KNU (Key Known Unknown), which is a simulation parameter described here.

(2) What the slider in  G2WS does ?

The slider simply changes the level of investment made by a geopolitical zone towards adaptation.

• Levels between 0 and 50 means that adaptation will be triggered by pain.

• Levels between 50 and 100 means that adaptation spendind starts from the first year.
