Methane - it's time to panic!

The Independent, not known for being, er, a good newspaper in any respect, has another article designed to scare the shit out of the organic falafel eating contingent in Primrose Hill:


In reality, methane is an issue because it is a greenhouse gas and actually a more powerful one than CO2. It therefore clearly needs to be monitored. According to the IPCC, methane concentrations in the atmosphere have risen due to human activities but have actually been falling over the past couple of decades. This is a trend that needs to continue and we need to keep an eye on global concentrations. One particular property of methane that helps alleviate concern to some extent is the fact that it has a relatively short residence time in the atmosphere. CO2 sticks around for a long time (this is one of the main reasons why it is such a problem), but this is less of an issue with methane.
