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.
The overall risks of climate change impacts can be reduced by limiting the rate and magnitude of climate change" [14] Working Group III: Without new policies to mitigate climate change, projections suggest an increase in global mean temperature in 2100 of 3.7 to 4.8 °C, relative to pre-industrial levels (median values; the range is 2.5 to 7.8 ...
In 2022, the Intergovernmental Panel on Climate Change (IPCC) released its Sixth Assessment Report on climate change. It warned that greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030 to have a good chance of limiting global warming to 1.5 °C (2.7 °F).
The Kyoto Protocol ( Japanese: 京都議定書, Hepburn: Kyōto Giteisho) was an international treaty which extended the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring and that human-made CO 2 ...
The Sixth Assessment Report ( AR6) of the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC) is the sixth in a series of reports which assess the available scientific information on climate change. Three Working Groups (WGI, II, and III) covered the following topics: The Physical Science Basis (WGI); Impacts, Adaptation and ...
Main sources of global methane emissions (2008-2017) according to the Global Carbon Project [ 40] Methane emissions come from livestock, manure, rice cultivation, landfills, wastewater, and coal mining, as well as oil and gas extraction. [ 41] Nitrous oxide emissions largely come from the microbial decomposition of fertiliser.
The Doha 2012 United Nations Climate Change Conference is an agglomeration of multiple related conferences being conducted roughly in parallel and in a semi-integrated fashion over the two weeks that the conference is in session: Eighteenth session of the Conference of the Parties (COP 18) Eighth session of the Conference of the Parties serving ...
