decade level, a warming trend becomes more apparent --
Graphs of other datasets (
NASA) show a greater warming trend, even during the period since 1998 --
I know that none of the data is faultless and every method of analysis requires compromises, inviting the potential for fraud, but when the vast majority of methods show long-term warming, I'll be unconvinced by one or two overwrought reworkings.
FDXLAG, you're right that the graph shows variation from the 100-year mean, but the the vertical axis is still considered the X-axis
(the Y-axis depicts years).
Go further back in time and we are in a fairly cool period for the last thousand years. Warmer temps were common as were cooler going back just 500 years. This is very inconvenient, so are the many failed efforts at modeling along with their dire predictions.
Start looking at the whole history of climate and understand the current muddle is almost meaningless as a statement of past or future climate.
