Patrick J. Michaels over at World Climate Report exposes the dishonesty in predicting that methane will increase along with CO2 during the next century. But the truth, confirmed by several studies, is that methane concentrations show "a persistent slowdown in the trends to nearly zero at present." [From Khalil et al, 2007. Atmospheric Methane: Trends and Cycles of Sources and Sinks. Environmental Science and Technology] Almost all the climate models assume that methane will increase, and this assumption is used in many scare-mongering stories. However, from conclusions in the article that World Climate Report writes on:
In describing the implications of their work, they note “it is questionable whether human activities can cause methane concentrations to increase greatly in the future.” Simple and well put.
It appears that we have to worry less about cow farts and smelly marshes than we thought.
