The 30 - y period 1951 — 1980 with relatively stable climate is sufficiently long to define

Let's say you claim a «slowdown» in 1998: you can use the data before then to estimate what
the climatological temperature is, e.g. by linear regression from 1970 - 1998.
When you start your «slowdown» trend, its initial value should be close to this estimated
climatological temperature, but to get the «slowdown» you have to ignore this information and allow some kind of magical jump in climatology during 1998.
Firstly, there's no significant change in trend (given ARMA (1,1) noise), and secondly it ignores knowledge about what
the climatological temperature is at the beginning of the trend.
If you look at all of the data and want to get a «slowdown» for some period at the end, then you have to assume there's some kind of jump in
climatological temperature just before the beginning of your «slowdown» period.
