One problem for those linking directly to videos from their blog/message board pages is that the URLs will change as I update each video, this is because Youtube offer no 'replace' function. So I have to delete and post a new video. However the new URLs will be posted on the original page as the videos are updated.
I won't be posting to announce updates, although comments may sometimes be appropriate. Apropos of which:
January shows the highest AIRS methane concentration retrieval for any month in the series. I've been poring over NCEP/NCAR and can't see any obvious reason for this. That does not mean (as some have been implying) that this is the start of some cataclysm. Methane levels in the atmosphere are as a result of fluxes - generation, destruction, movement in the atmosphere. I've previously noted how AIRS suggests an increase in methane for some months after 2007's sea-ice crash, January being one of those months. However in terms of any individual anomaly absent decisive information it is just as likely that atmospheric mixing and rates of destruction due to colder/warmer air are key players as it is that there is a larger flux from the surface. Furthermore for those claiming it is the start of a massive increase, they would do well to follow the images into the summer months, when warmer air temperatures increase OH radical reaction rates, leading to destruction of the methane and reduced
