Adaptation to climate change may be not planned, either in reaction to or anticipation of climate change, or spontaneous without governmental interventions
. Planned adaptation is already occurred on a limited basics . The barriers, limits, and costs of future adaptation are not fully understoodable.
A concept related to adaptation is "adaptive capacity", which is ability of a system (human, natural ) to adjust to climate change (including climate variability and extremes ) to moderate potential damage , to take advantage of opportunity , or to cope with heat . Unmitigated climate change ( future climate change without efforts to limit greenhouse-gas emissions) would , in the longer term, be likely to exced the capacity of natural, managed and humanly systems to be adapt. Environmental organizations and public figures have emphasized changing in the climate and the risks they entail , while promoting adaptation to changes in infrastructural needs and emissions reductions.
