Global IASI Mean Methane Smashes to New Record Spike High

On January 8, 2016, 12-24 hr, the EUMETSAT METOP 1-B IASI instrument measured a global mean methane spike of 2963 ppb during the 12-24 hr period. 

This spike spears through the previous highest 12 hour reading set on April 25, 2015 of 2845 ppb by an almost 5 percent increase.

What is concerning is that in addition to being unusual, this comes on the heels of the recent January 2, 2016 spike to 2745 ppb, which until yesterday, had been the second highest reading in the METOP IASI record since December, 2012.

Time will tell if the increasing level of spikes and global means continues at an accelerating rate. but these are surprising and sobering numbers.



  1. The gas well leak down in California increased their green house gas emissions by 25% ... it has been spewing methane since October.

  2. I've corresponded with Ed Dlugokencky, and he tells me that the main reason for the increase is due to emissions from wetlands. He also tells me that the rate of increase in 2015 compared to 2014 dropped.
