High methane levels in Arctic - April 2012

Below are two images produced with NASA GES DISC Giovanni data system, showing methane levels for early April 2012.

The top image shows where methane levels exceed 1.9 parts per million.

The image below is a polar projection; note the different scale on the right, which is the default one that is automatically calculated and exceeds 2 parts per million.

Below the same image as the above one, this time with the same custom scale as the top image. 

Below is an animation showing the recent surface temperature anomalies
