The terms have been used to describe the threat of global warming to the planet, and to urge aggressive climate change mitigation. For example, in the journal BioScience, a January 2020 article, stated that "the climate crisis has arrived" and that an "immense increase of scale in endeavours to conserve our biosphere is needed to avoid untold suffering due to the climate crisis."
The term Climate crisis, Climate emergency or Climate catastrophe is applied by those who "believe it evokes the gravity of the threats the planet faces from continued greenhouse gas emissions and can help spur the kind of political willpower that has long been missing from climate advocacy". They believe that, much as "global warming" drew out more emotional engagement and support for action than "climate change", calling climate change a crisis could have an even stronger impact.
