"Climate crisis" is a term that is used to describe global warming and climate change, and their effects. This term and the term "climate emergency" have been used to describe the threat of global warming to humanity and Earth, and to urge aggressive climate change mitigation and "transformational" adaptation. In the scientific journal BioScience, a January 2020 article that was endorsed by over 11,000 scientists states: "the climate crisis has arrived" and that an "immense increase of scale in endeavors to conserve our biosphere is needed to avoid untold suffering due to the climate crisis".
