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 ...
For example, climatologist Kevin E. Trenberth has published widely on the topic of climate variability and has exposed flaws in the publications of other scientists. [6] [7] [8] For past debates and controversies on scientific details see for example: History of climate change science#Discredited theories and reconciled apparent discrepancies ...
Climate change has been observed to have caused impact on human health and livelihoods in urban settings. [38] Urbanization commonly occurs in cities with low and middle income communities that have high population density and a lack of understanding of how climate change, which degrades their environment, is affecting their health.
Climate change vulnerability is a concept that describes how strongly people or ecosystems are likely to be affected by climate change. Its formal definition is the "propensity or predisposition to be adversely affected" by climate change. It can apply to humans and also to natural systems (or ecosystems).
Climate change denial refers to denial, dismissal, or doubt of the scientific consensus on the rate and extent of climate change, its significance, or its connection to human behavior, in whole or in part. [15] [6] Climate denial is a form of science denial. It can also take pseudoscientific forms.
Furthermore, a change in government might simply reverse that policy because the demand for palm oil would remain. Gates, however, was skeptical of other recent tactics used to mitigate climate ...
Drivers of climate change from 1850–1900 to 2010–2019. Future global warming potential for long lived drivers like carbon dioxide emissions is not represented. The scientific community has been investigating the causes of climate change for decades.
Climate change also increases both the frequency and intensity of extreme weather events, [7] which can directly wipe out regional populations of species. [8] Those species occupying coastal and low-lying island habitats can also become extinct by sea level rise. This has already happened with Bramble Cay melomys in Australia. [9]
