It is warmer 6 degrees in downtown Montreal compared to the surroundings of Mont Royal. Nevertheless, noted a researcher who wants to optimize the fight against heat islands.
By driving on her techno bicycle with a GPS. Meanwhile, electronic sensors, researcher Johanna Arnet noted, last week, a difference of 6 degrees Celsius between the Montreal skyscrapers and the Gazonnées du Mont Royal.

In addition to being harmful to biodiversity. heat islets cause respiratory and cardiac problems and promote floods in the event of intense rains.
50 hours of observation
In the context of his master’s degree in co -director at Quebec universities in Montreal. Concordia, Mme Arnet undertook, last year, an immense collection of data on the temperature felt by pedestrians, solar radiation and ground temperature in five sectors of the island.
“We know that planting trees can reduce the effects of heat islands. My goal is to document where we could intervene to optimize these plantations, ”she explains.

By bike for science
“The interest of doing this bicycle work is to allow information to record information in several places. at different times of the day,” explains Mme Arnet.
It was at 3 p.m. that she started driving for science for two hours. Second data entry takes place from it warmer 6 degrees downtown 11 p.m. to 1 a.m.
