Yes I agree with you.

If you would like to draw trend lines, they are down.

I gather from the graphs that multiple measurements are taken per year.
Since the graphs provides up to date data and is inherently noisy (mainly due to seasonal variations), a moving average
is not being used to calculate the temperature anomalies on the Y axis.
The anomalies are therefore calculated using a baseline value.
The obvious question is how has the baseline value been determined?
