CAMS' new data for methane emissions

Reading the new CAMS data

For the tiny group of people interested in following evidence.

See the large BLUE area (and think of the psychological messaging there) and then look at the colour chart - the new system and then the old. The blue represents 1800 ppb which until recently was the AVERAGE.

There is nothing much below that level. The 'average' has been turned into 'low'.

Here is the GLOBAL view at 500 hPa.

Similarly, the GREEN, which looks ever-so-normal, represents somewhere represents approximately 1900 ppb which, I believe, is the new 'average'.

How long before the red and dark brown become the 'new average'?

I strongly suggest you save the comparative colour code. It might save you from getting COMPLETELY THE WRONG IDEA about the state of play concerning methane.

It is dire.

Q: What is the correct number for dark brown areas?

A: Thats a moot point. There is none. It used to be somewhere between 2040 and 75,600 ppb. Now it is somewhere between 2140 and 10,000 ppb. We are none the wiser.
