New data for 2019 show record-breaking levels of methane in the atmosphere within a fragile Arctic region.

OK, this is just BS. The only site where methane samples are collected anywhere in the north that shows this "effect" is Barrow. Why is that ....it is all "preliminary data" as indicated by the orange color. Here is what NOAA says about the preliminary data:

Warning: Preliminary data include the this group's most up-to-date data and have not yet been subjected to rigorous quality assurance procedures. Preliminary data viewed from this site are "pre-filtered" using tools designed to identify suspect values. Filtering is performed each time a data set containing preliminary data is requested. Filtering, however, cannot identify systematic experimental errors and will not be used in place of existing data assurance procedures. Thus, there exists the potential to make available preliminary data with systematic biases. In all graphs, preliminary data are clearly identified. Users are strongly encouraged to contact Dr. Pieter Tans, Group Chief (pieter.tans@noaa.gov) before attempting to interpret preliminary data.


we have seen this countless times before. People freak out because of preliminary data that gets downgraded a few months later. Folks need to remember that methane is a well mixed gas. If you see an uptick in the Arctic that should appear everywhere in North America in 6 months time.
