1 Ιουν 2022 · The table below shows the relative concentrations of these major greenhouse gases and their sources. Some gases (like CO 2 ) are made by both natural and manmade processes, while others (like hydrofluorocarbons) are only the result of human industrial activity.
The major anthropogenic (human origin) sources of greenhouse gases are carbon dioxide (CO 2), nitrous oxide (N 2 O ), methane and three groups of fluorinated gases ( sulfur hexafluoride ( SF 6 ), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs, sulphur hexafluoride (SF 6 ), and nitrogen trifluoride (NF 3 )).

15 Νοε 2023 · According to WMO’s Greenhouse Gas Bulletin, released in 2024, atmospheric levels of the three main greenhouse gases - carbon dioxide, methane and nitrous oxide all reached new record highs in 2023.
For climate change, the most important greenhouse gas is carbon dioxide, which is why you hear so many references to “carbon” when people talk about climate change. There are three main reasons CO 2 is so central to the global warming happening today.
13 Μαΐ 2019 · Major greenhouse gases and sources. Carbon dioxide (CO 2): Carbon dioxide is the primary greenhouse gas, responsible for about three-quarters of emissions.
Total greenhouse gas emissions are the sum of emissions of various gases: carbon dioxide, methane, nitrous oxide, and smaller trace gases such as hydrofluorocarbons (HFCs) and sulfur hexafluoride (SF6). How much does each gas contribute to global greenhouse gas emissions?
The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space. Five key greenhouse gases are carbon dioxide, nitrous oxide, methane, chlorofluorocarbons, and water vapor.
