The rise is in line with an image from an earlier post that shows growth of CO₂ in the atmosphere to be accelerating.

And it's not just carbon dioxide emissions that are rising. Methane emissions are rising as well. Sadly, politicians typically ignore this elephant in the room, i.e. seafloor methane emissions that threaten to trigger a huge temperature rise within years.

The MetOp image shows many areas where no data were available, as indicated by the color grey. The NPP images don't have as many grey areas. The image below confirms very high methane levels over the Arctic Ocean on December 9, 2018 pm, closer to the surface, i.e. at 840 mb. While there still are many grey areas, the absence of data for many of them is due to altitude, since large parts of Greenland, Antarctica and the Himalayas are rather high.
As discussed in earlier posts, large amounts of methane appear to be rising from the Arctic Ocean. As the methane rises higher in the atmosphere, it moves closer to the Equator. The NPP image below shows levels at 399 mb on December 9, 2018, pm. At this altitude, there are very few grey areas, so it's possible to get a fuller picture of where the highest levels of methane are. Ominously, levels as high as 3060 ppb were reached.
The situation is dire and calls for comprehensive and effective action, as described at the Climate Plan.
