Related: About this forumPeak Methane Spike to 2845 Parts Per Billion on April 25, 2015 is Just Uncanny
Sam Carana over at Arctic News caught the spike earlier this week and provided this very informative graph cataloging 14,000 to 18,000 foot methane levels for 2015:
(Daily mean and peak values provided by Sam Carana show how much of an outlier the April 25 spike is. Image source: Arctic News.)
And what we find, from looking at the graph, is that not only did peak values spike to an extraordinary high level in late April, but mean values also took a big jump rising from 1807 ppb on January 10 to a peak of 1829 ppb on April 22nd. A 12 parts per billion bump in the entire global measure over a four month period (average annual rates of increase have been in the range of 7 parts per billion each year recently). A raging pace of increase 5 times faster than the annual trend.

And one spike doesn't make a feedback. We've had these methane panics from outlying data before. Let's wait and see what happens.
