Fossil fuel divestment or fossil fuel divestment and investment in climate solutions is an attempt to reduce climate change by exerting social, political, and economic pressure for the institutional divestment of assets including stocks, bonds, and other financial instruments connected to companies involved in extracting fossil fuels.
Fossil fuel CO 2 emissions on log (natural and base 10) scales. The graphic shows the logarithm of 1850–2019 fossil fuel CO 2 emissions; [85] natural log on left, actual value of Gigatons per year on right. Although emissions increased during the 170-year period by about 3% per year overall, intervals of distinctly different growth rates ...
Commonly, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived entirely from biological sources, such as tar sands. These latter sources are properly known as mineral fuels. Fossil fuels contain high percentages of carbon and include coal, petroleum, and natural gas. [12]
Note that although coal, oil and natural gas are derived from sunlight, [5] they are considered primary energy sources which are extracted from the earth (fossil fuels). Natural uranium is also a primary energy source extracted from the earth but does not come from the decomposition of organisms (mineral fuel).
Estimating the remaining fossil fuels on the planet depends on a detailed understanding of Earth's crust. With modern drilling technology, we can drill wells in up to 3 km of water to verify the exact composition of the geology; but half of the ocean is deeper than 3 km, leaving about a third of the planet beyond the reach of detailed analysis.
Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...

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 ...
Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases.
