But if it does start appearing elsewhere, it's a very bad sign.
Barrow is in the Arctic and the methane spike is possibly showing a feedback loop kicked off by thawing permafrost and/or frozen methane hydrates.
Methane is a powerful greenhouse gas, more powerful than CO2, and is implicated in past mass extinctions.
On top of this spike, along with record low ice, record temperatures, and Siberian fires and floods, we have the following evidence of major problems in the Arctic ...

And so on ...
For now, let's hope the graph just shows some sort of weird methane burp from somewhere around Barrow.

Orange numbers are described as preliminary, but it is concerning regardless. Some other high-latitude station methane readings are shown, they don't seem to show the same increase.

Even after correction the trend remains strongly upward.

Barrow CO2 graph added FYI.
After the unprecedented global industrial slowdown from COVID, if there is no substantial drop in methane and CO2 output, and a trend downward, then it is probably correct to assume the worst for our ecosystems.
No Green policy is likely to achieve what the virus has done in terms of greenhouse gas reduction.

There is also a very slow refreeze of Arctic ice so far this year, on the back of the second lowest recorded ice extent. NSDIC graph attached.
What is interesting in the Barrow methane data are the orange + symbols. According to the NOAA website these symbols show data "that are thought to be not indicative of background conditions, and represent poorly mixed air masses influenced by local or regional anthropogenic sources or strong local biospheric sources or sinks".
Note that all the + symbols are above the trend line, with none below.
Nonetheless, methane emissions must be seen to be increasing elsewhere around the Arctic to better understand what is happening.

As you'll see from this thread it has been consistently peaking.

This trend at Barrow is particularly concerning given findings by the recent Arctic mission studying methane clathrates.

Note that orange dots are data not yet quality checked and the orange + symbols were formerly orange dots. The NOAA website says the orange + symbols show data "that are thought to be not indicative of background conditions, and represent poorly mixed air masses influenced by local or regional anthropogenic sources or strong local biospheric sources or sinks".
As stated earlier, it is perhaps interesting that the orange + symbols are above the trend line.
