CET vs Grape harvest

The first plot shows yearly comparison with temperature not inverted and not filtered.
The second plot show the full grape harvest period with axes scaled and temperatures inverted.

Obviously the Pinot Noir grape varieties have changed over the years and CET is not the temperature of the area where the grapes are farmed. Still gives a reasonable match!

How much warming

From post on WUWT:

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.
