This involves deep reductions in emissions of methane and black carbon: at least 35% of both by 2050, relative to 2010, to limit warming near 1.5 °C. Such measures could be undertaken in the energy sector and by reducing nitrous oxide and methane from agriculture, methane from the waste sector, and some other sources of black carbon and ...
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 public substantially underestimates the degree of scientific consensus that humans are causing climate change. [16] Studies from 2019 to 2021 [17] [18] [19] found scientific consensus to range from 98.7–100%.
Emission trajectories needed to achieve the Paris Agreement's two-degree target without negative emissions, depending on the emission peak. Evolution of land and sea temperatures 1880-2020 compared to the 1951-1980 average.
The widespread adoption of a vegetarian diet could cut food-related greenhouse gas emissions by 63% by 2050. [110] China introduced new dietary guidelines in 2016 which aim to cut meat consumption by 50% and thereby reduce greenhouse gas emissions by 1 Gt per year by 2030. [ 111 ]
The Paris Agreement (also called the Paris Accords or Paris Climate Accords) is an international treaty on climate change that was signed in 2016. [3] The treaty covers climate change mitigation, adaptation, and finance.
