For the climate system, the term refers to a ...

[34] Since the 2000s, climate change has ...
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 ...
In another tipping point, worsening climate hazards are now making insurance unaffordable, with half a million homes in Australia alone set to be uninsurable by 2030, they said.
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 ...
[citation needed] However, a 2018 published study points at a threshold at which temperatures could rise to 4 or 5 degrees through self-reinforcing feedbacks in the climate system, suggesting the threshold (or 'tipping point') is below the 2 degree temperature target.
