Using trees to beat the heat: action in Portland Oregon.

From this interesting piece from the USA:
New street tree in Keith neighbourhood,
Hamilton Ontario

"We’ve been working with a team for several years to develop heat island maps for Portland and its surrounding region. We’ve also worked with Dr. Linda George and her lab to study traffic-related air quality, and the impact of trees on that air quality."

"Right now we’re working on an interactive version of the map that will help policy makers and citizen groups drill down on specific Portland streets and neighborhoods to find trouble spots. Notable in our analysis is that trails and greenways factor prominently in reducing air pollution and mitigating urban heat. The more extensive tracts of greenery present in specific areas, the greater cleaning and cooling of the air."

OK peoples: we can do so much more to further the research about air quality, and keep adding more trees to do their part for cleaning the air.
