The concept of social tipping points has been applied to analyze global decarbonization pathways and the ability to activate contagious and fast-spreading processes of social and technological change that would accelerate carbon emission reductions needed to achieve the goals of the Paris Agreement.

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 ...
Due to the impacts of climate change on mental health, psychologists and social workers have begun to take climate into account when assessing patients. This includes reaching out to the community and applying psychological principals to decrease climate change and to address climate anxiety in clinical sessions.
The mid-20th century marked a significant turning point in climate science. In 1958, Charles David Keeling began precise measurements of atmospheric CO2 at the Mauna Loa Observatory, revealing a consistent upward trend known as the Keeling Curve. This data highlighted the direct correlation between human activity—specifically fossil fuel ...
They believe, much as global warming provoked more emotional engagement and support for action than climate change, [2] [6] [7] calling climate change a crisis could have an even stronger effect. [2] A study has shown the term climate crisis invokes a strong emotional response by conveying a sense of urgency. [8]
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 change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
