A climate change global warming “tipping point” can occur when only moderate additional warming causes strong positive feedbacks that cause further runaway warming. Examples of “tipping point” processes include the increased absorption of sunlight as melting ice exposes darker surfaces, another example is the increase in the discharge of icebergs from ice shelfs as oceans warm or the release of the greenhouse gas methane from peat moss bogs as they unfreeze is temperatures warm. The increased release of dissolved carbon dioxide from the world’s oceans as they warm is another potential “tipping point”.
