to note that what is a feasible adaptation response at one point in time may change with the level of warming experienced-some techniques will be become less effective at higher levels of warming. With global temperature rises of <2ºC, in many cases, it will be realistic to build resilience and maintain species and ecosystems in situ, but, at higher levels of warming, this will become increasingly difficult; managing inevitable change, including the consequences of loss and damage, will be important . Similarly, to be effective at higher levels of warming may require the adaptation of the EbA approaches themselves . We have therefore not attempted a global-scale assessment of the feasibility of adaptation options, but rather present some key cross-cutting considerations in assessing feasibility for adaptation of and through ecosystems.
