Climate change could result in global, large-scale changes in natural and social systems.[162] Two examples are ocean acidification caused by increased atmospheric concentrations of carbon dioxide, and the long-term melting of ice sheets, which contributes to sea level rise.[163]
Some large-scale changes could occur abruptly, i.e., over a short time period, and might also be irreversible. An example of abrupt climate change is the rapid release of methane and carbon dioxide from permafrost, which would lead to amplified global warming.[164][165] Scientific understanding of abrupt climate change is generally poor.[166] The probability of abrupt change for some climate related feedbacks may be low.[164][167] Factors that may increase the probability of abrupt climate change include higher magnitudes of global warming, warming that occurs more rapidly, and warming that is sustained over longer time periods.
