This article is a list of locations and entities by greenhouse gas emissions, i.e. the greenhouse gas emissions from companies, activities, and countries on Earth which cause climate change. The relevant greenhouse gases are mainly: Carbon dioxide, Methane, Nitrous oxide and the fluorinated gases [2] bromofluorocarbon, chlorofluorocarbon, hydrochlorofluorocarbon, [3] hydrofluorocarbon, [4 ...
The Fifth Assessment Report ( AR5) of the United Nations Intergovernmental Panel on Climate Change (IPCC) is the fifth in a series of such reports and was completed in 2014. [1] As had been the case in the past, the outline of the AR5 was developed through a scoping process which involved climate change experts from all relevant disciplines and ...
Shared Socioeconomic Pathways ( SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. [2] They are used to derive greenhouse gas emissions scenarios with different climate policies.
Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. [14] IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere.
The Intergovernmental Panel on Climate Change ( IPCC) is an intergovernmental body of the United Nations. Its job is to advance scientific knowledge about climate change caused by human activities. [1] The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) set up the IPCC in 1988. The United Nations endorsed the creation of the IPCC later that year. [2 ...
Climate change has led to the United States warming by 2.6 °F (1.4 °C) since 1970. [3] The climate of the United States is shifting in ways that are widespread and varied between regions. [4] [5] From 2010 to 2019, the United States experienced its hottest decade on record. [6] Extreme weather events, invasive species, floods and droughts are increasing. [7] [8] [9] Climate change's impacts ...
The IPCC's attribution of recent global warming to human activities reflects the view of the scientific community, [9] [10] [11] and is also supported by 196 other scientific organizations worldwide. [12] ( See also: Scientific consensus on climate change.
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.
