Many people see this picture and believe they are somehow magically observing temperatures. But all they are seeing is a line which somebody drew.
This is what I see :
Devil is in the details.
No values shown on the chart.
What is “land-ocean temperature”?
They used 1880-1910 as the average.
Funny, 1880 to 1910 was a cooling period. Then it starts to warm around 1910.
See the graph: https://en.wikipedia.org/wiki/Instrumental_temperature_record
According to the graph, it has warmed .5C since 1880.
No Tom Wigley left !! All gone
And no, that is NOT a line of observed temperatures,
It is a much adjusted and fabricated load of sewerage.
Land-ocean is not observations, it is a product made from temp readings, interpolations, omissions, adjustments and other machinations. Perhaps a useful, non-digestive metaphor might be: L/O is to temp as Almonds are to Nutella, or Wheat is to White bread. The reality and character of the input has been lost during the processing, and variations in the nuts and kernels can no longer be detected.
Or, for a more oeonophilic comparison: all the things that can go into a bottle, and still call it ‘Cabernet’.
As if we didn’y know
I see a graph of temperatures. Regardless of whether or not the graph is correct, the graph does not show what is causing them to change, what factors are causing what fraction of the changes, and no empirical proof of any of it.
Sadly, many people see only the graph and presume what the cause is because they’re brainwashed to think of what it is supposed to be.
