Carbon dioxide tends to take all the headlines relating to greenhouse
gases. After carbon dioxide comes methane and nitrous oxide, with
few people giving much thought to the contribution of other greenhouse
gases to climate change.
Though their concentrations are tiny compared to carbon dioxide,
concentrations of many of these other greenhouse gases are increasing
When this is combined with the fact that many are also extremely
powerful greenhouse gases, with residence times in our atmosphere
of hundreds or even thousands of years then it becomes clear that
they should be included in any discussion of greenhouse gases.
