Without even plotting the data, it seems to be very obvious to me. Starting out at 13-14 degrees annually at the beginning of the recording, it is now pretty solidly 16-17 degrees. The last year under 16 was 1996. If that isn't a dramatic change, I don't know what is. So this data actually pretty much exactly matches the French data.
