Climat Change is not a commie myth.

[pocaracas]

Maybe I'm reading the plot wrong, but the zero seems to be the temperature at 1900 (start of the horizontal axis). Everything else is the difference to the temperature at 1900.

IF that is the interpretation, temp in 1900, why not pick some later year? Say I pick the blue one that looks like around 1917 or the red one around 1922 and make either of them zero. That shifts the chart immensely. There is NOTHING meaningful or sacred about years that end in 0 or 00. 1900 is both arbitrary and capricious.

Of course, if we just follow the link min posted.... we may just find out how they did it:

This graph uses the 1901 to 2000 average as a baseline for depicting change. Choosing a different baseline period would not change the shape of the data over time.

The shape will remain the same, only the amount of blue and red gets exchanged.
