Also called global warming denial. climate change feedback A natural phenomenon that may increase or decrease the warming that eventually results from a change in radiative forcing. climate change mitigation approaches to limit global warming, primarily by the substitution of fossil fuels with low-carbon sources of energy climate commitment How much future warming is "committed", even if ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [28]
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 emphasize the threat of global warming to Earth's natural environment and to humans, and to urge aggressive climate change mitigation and transformational adaptation.

Global warming affects the insurance and financial services sectors. [146]: 212–213, 228, 252 Insurance is an important tool to manage risks. But it is often unavailable to poorer households. Due to climate change, premiums are going up for certain types of insurance, such as flood insurance.
Changes recorded in the climate of Greenland at the end of the Younger Dryas, as measured by ice-cores, imply a sudden warming of +10 °C (+18 °F) within a timescale of a few years. [9] Other abrupt changes are the +4 °C (+7.2 °F) on Greenland 11,270 years ago [10] or the abrupt +6 °C (11 °F) warming 22,000 years ago on Antarctica. [11]
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity).
Climate endgame is a term used to refer to the risk of societal collapse and potential human extinction due to the effects of climate change. [2] The usage of the term seeks to improve risk management by putting a higher priority on worst-case scenarios , to "galvanise action, improve resilience, and inform policy ".
[B.3] Continued global warming is projected to further intensify the global water cycle, including its variability, global monsoon precipitation and the severity of wet and dry events. [B.5] Many changes due to past and future greenhouse gas emissions are irreversible for centuries to millennia, especially changes in the ocean, ice sheets and ...
