I'll read it more thoroughly later. My quick impression, more from the abstract than the
main text, is that you are defensive and it almost seems that there is a denial of the UHI
in part. Yet later in the abstract and nicely in the first two sentences of the
conclusions, you recognize that the UHI is real and the climate is different in cities.
The point is that the homogenization takes care of this wrt the larger scale record and
that UHI is essentially constant at many sites so that it does not alter trends. So I urge
you to redo the abstract and be especially careful of the wording.
You might even start with:
The Urban Heat Island (UHI) is a real phenomenon in urban settings that generally makes
cities warmer than surrounding rural areas. However, UHIs are evident at both London and
Vienna, but do not contribute to the warming trends over the 20th century because the city
influences have not changed much over that time. Similarly, ...

Anyway - I'd appreciate if you could have a look at this draft. I have
spelt things out in some detail at times, but I'm expecting if it is published
that it will get widely read and all the words dissected. I know you're all
very busy and I could have been doing something more useful, but it hasn't
taken too long.
The European examples are just a simple way to illustrate the difference
between UHIs and urban-related warming trends, and an excuse to
reference Luke Howard.
