In studying the subject in even more detail over the 1950-2013 period, it was further found that this phenomenon could “account for between 70 and 80% of the recorded warming trend in Western Mediterranean cities.”

And in light of this discovery, Quereda et al. pose the important question: “are urban areas contributing to the observed warming trend on which climate change is based?” to which they respond by stating that “the answer to be drawn from our analysis is fully affirmative.”

And so they conclude by stating that “in these Western Mediterranean cities, the Urban Heat Island could account for up to 80% of the recorded warming.”
