In common usage, climate change describes global warming —the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate.
Ozone depletion is not a primary cause of climate change, however there exists a physical science connection between the two phenomena. The Earth's atmospheric ozone has two major effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.
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. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre ...
Simple global-scale estimates [83] that recently have been actualized [84] and confirmed by more refined model calculations [85] [86] show noticeable contributions from waste heat to global warming after the year 2100, if its growth rates are not strongly reduced (below the averaged 2% p.a. which occurred since 1973). Evidence for warming ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 9 October 2024. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Definition. The global warming potential (GWP) is defined as an "index measuring the radiative forcing following an emission of a unit mass of a given substance, accumulated over a chosen time horizon, relative to that of the reference substance, carbon dioxide (CO 2). The GWP thus represents the combined effect of the differing times these ...
Box office. $49.8 million [3] An Inconvenient Truth is a 2006 American documentary film directed by Davis Guggenheim about former vice president of the United States Al Gore 's campaign to educate people about global warming. The film features a slide show that, by Gore's own estimate, he has presented over 1,000 times to audiences worldwide.
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
