Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Some large-scale changes could occur abruptly, that is to say, 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. It is believed that 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. Therefore, global warming could result in serious problems to every one of us in the near future.
