Climate change: A nasty surprise in the greenhouse

The Kyoto Protocol aims to reduce emissions of greenhouse gases such as methane. But it seems that the fall in human-induced methane emissions in the 1990s was only transitory, and atmospheric methane might rise again.

Methane is a potent greenhouse gas — per molecule, more than 20 times as powerful as carbon dioxide1. Moreover, when methane emissions rise, so too does the concentration of the pollutant ozone in the troposphere, the lowest layer of Earth's atmosphere2.
