ie, a look at the actual temperature in the central england data set from the 1600's, would give a null hypothesis for any significant observable human AGW signature (ie a low % of AGW) as there only appear to be a gradual
warming trend from a period known as the «little ice age».
The fact is that
the warming trend from 1970 to 2012 is higher than the trend from 1970 to 1997.
o YES: The early warming had been caused by the West Spitsbergen Current, while the second warming was actually marking the end of the interrupted
warming trend from 1940 to 1970s presumably partly due to the naval warfare during WWII.

In SW — seen here as a cloud cover —
a warming trend from reducing cloud between the mid 1980's and 1990's equivalent to about 2 W / m ^ 2 change, a step change in the late 1990's in the 1998/2001 climate shift and a plateauing since.
The first part of the adjustment removes
a warming trend from the urban record, as we would expect.
The only thing that maybe correct in the analysis is the oscillation, because
the warming trend from the mini ice age is in the data too.
We can see that, as expected, the program applied quite heavy adjustments to the early part of the records, removing about 0.8 °C / century of
a warming trend from the period from 1895 - 1980.
On this basis, they seem to have decided that it doesn't matter whether their computer program removes
a warming trend from the data or introduces one!
So, the only thing we can say about sat readings is sat reading show a slight
warming trend from the 1980's onward.
If, for example, we were to create a piece-wise continuous trend keeping your own trend, we'd find the 0.17 C decadal
warming trend from your starting point preceded by an estimated warming of equal magnitude in the combined 125 prior years (beginning at a time where only 1/4 of the present day coverage existed, thus placing the entire 125 year warming more or less within the margin of statistical insignificance).
Yet after all that, here you are, saying things like «Looks like an oceanic warming trend corresponding to the atmospheric
warming trend from 1979 through 1998 begins around 2000, suggesting a delay of ca. 21 years.»
