In this graphic, you can see methane concentrations (dark lines) and the amount of carbon-13 (heavy carbon) in the methane (light lines) from 1998-2014 for four latitude zones: Northern and Southern Hemisphere tropics (green and orange) and Northern and Southern high latitudes (blue and gray). Starting in 2007, methane concentrations in all latitude zones began to rise, but the amount of methane carrying "heavy" carbon-13 started to fall.

#noaa #science #climate #climatechange #globalwarming - travisloebsInteresting infographic! A few questions after reading the article. Do you know the cause of the relative decrease in carbon-13? There appears to be a lag between the increase in methane and the relative decrease in carbon-13, possibly suggesting the two trends are being driven by different factors. This should be looked into further. What other factors are you considering and what methods are you using for modeling and/or hypothesis testing?
