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.
Climate change feedbacks are natural processes that impact how much global temperatures will increase for a given amount of greenhouse gas emissions. Positive feedbacks amplify global warming while ne
Lapse rate (green) is a negative feedback everywhere on Earth besides the polar latitudes. The net climate feedback (black) becomes less negative if it were excluded (orange)
This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, soil and oceans in billions of tons of carbon per year. Yellow numbers are natural fluxes, red are human contributions in billions of tons of carbon per year. White numbers indicate stored carbon.
Methane climate feedbacks in natural ecosystems.
Nine probable scenarios of greenhouse gas emissions from permafrost thaw during the 21st century, which show a limited, moderate and intense CO2 and CH4 emission response to low, medium and high-emission Representative Concentration Pathways. The vertical bar uses emissions of selected large countries as a comparison: the right-hand side of the scale shows their cumulative emissions since the start of the Industrial Revolution, while the left-hand side shows each country's cumulative emissions for the rest of the 21st century if they remained unchanged from their 2019 levels.
