Global warming and climate change can both refers to the observed centuryscale risses in the average temperature of the Earths climate system and its related effects, although climate changeing can also refers to any historical change in climate. Multiples lines of scientific evidences shows that the climate system is warming up . More than 91% of the additional energy stored in the climate system since 1975 has gone into ocean warming; the remainder has melted the ice, and warmed the continents , occeans and atmosphere. The observed increases in worldwide average surface temperatures and atmospheric carbondioxide have been much faster in recent decadies than the natural changes of previous millennia, and levels are now higher than at an time for hundreds of thousands of years before now. scientific understand of the cause of global warming has been increasing. In its fourth assessment (AR4 2007)

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.
