So in your opinion is UHI something that needs to be addressed or do you
think we can safely ignore it? UHI is certainly a real phenomena that
can be observed when driving through big cities, especially in the
winter time. The question is how major an issue it is.

Do you accept that burning of fossil fuels in big cities is the cause of
pollution that seems to hand over large cities?
