WHAT ARE CLIMATE OR GREENHOUSE GASES?
In addition to carbon dioxide (CO2), the trace gases methane (CH4), nitrous oxide (N2O), a number of the hydro-fluorocarbons (H-FKW, HFSs, KFW and PFCs), together with sulphur hexaflouride (SF6) are listed as greenhouse gases. These all have a negative effect on climate, since they ensure, as a combination of trace gases in the atmosphere, that heat radiation, rather than escaping into space, is trapped and heats up the atmosphere.
