What is evident from my plot is that the period from 1985 to present does not (yet !!) conform to the general linear trend. Adding a trend line to 1985 to present gives a warming of 4.4degC/century (got it right this time I think)
The current trend in CET is negative so there is a possibility that in a decade or so there will be a return to the .3C/100year average. But can we wait to find out?
Looking at satellite data:
data: http://discover.itsc.uah.edu/amsutemps/
the channel CHLT (no longer reported – too much of an incline??!!) gives a temp increase of 11C/century.
It would be interesting to know why this channel was dropped.
