Methane emissions

Increasing methane emissions are a major contributor to the rising concentration of greenhouse gases in Earth's atmosphere, and are responsible for up to one-third of near-term global heating. During

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
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.
