(1) KNU 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.

Adaption is modeled in CCEM as an insurance policy that geopolitical powers may take. If they spend money, they increase their protection against storms, flood, fires, heat waves ... so that the impact of global warming (see damages) is reduced.

(2) What the slider in  G2WS does ?

The slider simply changes the risk reduction factor. The KPI that is returned to measure the slider effect is the protection rate that is reached in 2100, that is the proportion of damages that may be avoided. Note that this requires both adaptation to be effective and used (two sliders).
