Since 2007, methane concentration in the atmosphere has increased year-to-year. Some years the bulk of this increase is from the poles; in other years it seems to be from the equator and subtropics (either Northern or Southern Hemisphere). I ponder these patterns, and what it means. We can get info on the source of methane increases by looking at the carbon-13 isotope levels within the CH4 molecule. As the Arctic darkens from exponential loss of sea-ice and spring snow cover, the risks of large episodic bursts of methane increase.
