Greenhouse gas emissions from human activities intensify the greenhouse effect which contributes to climate change. Carbon dioxide from burning fossil fuels is the main cause of climate change. The la

Greenhouse gases are the gases in an atmosphere that trap heat, raising the surface temperature of astronomical bodies such as Earth. Unlike other gases, greenhouse gases absorb the radiations that a

…atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Over 60 billion tons were emitted in 2025, higher than any year before. Total cumulative emissions from 1870 to 2022 were 703 GtC (2575 GtCO2), of…
Comparison of global warming potential of three greenhouse gases over a 100-year period (GWP-100) per ton: Perfluorotributylamine (PFTBA), nitrous oxide and methane, compared to carbon dioxide (the latter is the reference value, therefore it has a GWP of one). PFTBA is here used as an example of a larger group of potent fluorinated greenhouse gases. Fluorinated hydrocarbons combined contribute about 10% to global warming.
This 1912 article succinctly describes how burning coal creates carbon dioxide that causes climate change.
