Dyma ddiffiniad 'runaway', yng nghyd-destun y newid yn yr
hinsawdd:
Runaway climate change describes a theoretical
scenario in which the climate system passes a threshold or tipping point, after which
internal positive feedback effects cause the
climate to continue changing without further external forcings. The runaway climate change
continues until it is overpowered by negative feedback effects which cause the
climate system to restabilise at a new state.
Dyma dri chynnig o wefan y Cynulliad:
newid di-droi’n-ôl yn yr hinsawdd
newid andwyol yn yr hinsawdd
newidiadau na ellir eu rheoli yn yr hinsawdd
Ydy'r cyntaf o'r rhain yn fwy addas? Neu a all unrhyw un
gynnig rhywbeth gwell?
Hefyd, ydy 'trobwyntiau' yn addas ar gyfer 'tipping
points'? Dyma ddiffiniad:
A climate tipping point is a point when global climate changes from one stable
state to another stable state, in a similar manner to a wine glass tipping over.
After the tipping point has been passed, a transition to a new state occurs. The
tipping event may be irreversible, comparable to wine spilling from the
glass—standing up the glass will not put the wine back.
Diolch!
