Are all green house gases natural occurring?

    The most important greenhouse gases, like carbon dioxide and methane, are naturally-occurring compounds, but are now being produced at much higher than natural rates. However there are some less common greenhouse gases, including hydrofluorocarbons and perfluorocarbons, which are completely synthetic compounds and do not occur in nature. In the end though, whether or not a gas is “natural” is not the most important thing when it comes to its impact on the climate. Carbon dioxide, for example, is naturally occurring – and in fact we need a certain amount of it in the atmosphere to keep the planet from being too cold. Yet human activities are now putting much, much more carbon dioxide in the atmosphere than the planet is used to, with the result that our climate is changing faster than it has at any time in over 60 million years.

    Although the majority of greenhouse gases like CO2 are natural and are released through natural means (burning oil for example), there are some man-made greenhouse gases. Many of these like hydrofluorocarbons are far worse for the environment though, containing significantly longer atmospheric half-lives and trapping far more solar radiation per unit than other, naturally occurring greenhouse gases, thus speeding up the effects of Climate Change.
