There are thousands of temperature stations. If you have an agenda, it's
easy to cherry-pick some that show the adjustments you are interested in.

If one suspect that adjustments are systematically biased in one direction,
the correct thing to do is to take all of them and look at their
distribution. This is the result for the entire GHCN dataset, on which GISS
is based:

You get a nice gaussian distribution with an average of 0 degrees. That is,
there are as many negative adjustments as there are positive ones.
