The 2019 IPCC Special Report on the Ocean and Cryosphere in a Changing Climate defines a tipping point as: "A level of change in system properties beyond which a system reorganises, often in a non-linear manner, and does not return to the initial state even if the drivers of the change are abated. For the climate system, the term refers to a ...
New research suggests the Greenland ice sheet is on track to cross a critical threshold that could cause runaway melting, but that it’s also possible the threshold will be crossed temporarily ...
A new study in the journal Science finds that even the most aggressive goals of reducing greenhouse gas emissions aren’t sufficient to avoid several major climate change tipping points, in which ...
Problems of global warming, climate change, and their various negative impacts on human life and on the functioning of entire societies are one of the most dramatic challenges of modern times. PAS General Assembly calls on the national scientific communities and the national government to actively support Polish participation in this important ...
Tipping point (sociology), an event when a previously rare phenomenon becomes rapidly and dramatically more common; Tipping point, in catastrophe theory, the value of the parameter in which the set of equilibria abruptly changes; Tipping points in the climate system, thresholds that, when exceeded, can lead to large changes in the state of the ...
A new study that reassesed decades of work of climate "tipping points" has revealed they are more numerous and closer to being triggered than researchers initially feared.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Climate sensitivity may further change if tipping points are crossed. It is unlikely that tipping points will cause short-term changes in climate sensitivity. If a tipping point is crossed, climate sensitivity is expected to change at the time scale of the subsystem that hits its tipping point.
