Changing public perceptions of climate change
Beyond its usefulness for researchers, the newly developed apps will also make valuable resources for the public. Nazemi says they specifically created a search function that would allow someone to compare data from any Canadian station in a reference year with current condition, a simple comparison, which can demonstrate how climate has changed over time.
“The public perception of climate change is rather biased as it is viewed often as a political issue,” he says. “We wanted to inject some factual knowledge here and help change how Canadians perceive a critical societal issue like climate change.”
Nazemi and Jiwa conceived of the portal last summer. Jiwa joined Nazemi’s lab after taking his calculus course and led the developments of the three apps.
“Hearing about the field of hydrology and contemplating its future impacts really sparked my interest in pursuing a project like this,” Jiwa explains.
Nazemi asked Jiwa if it would be possible to develop a solution to a colleague’s struggles with downloading climate station data. In response, Jiwa developed a set of computer codes to pull data directly from the Environment and Climate Change Canada repository — meaning the portal will always be up to date.
Since then, the project has evolved tremendously.
“Nazemi inspired me in terms of what researchers would be looking for when they’re getting data, and we gradually added several new features and filters,” Jiwa says.
‘We need to have that data so we can plan for the future’
Having access to all publicly-available climate stations in Canada, Jiwa and Nazemi developed a new visualization for the evolution of the Canadian climate network over Canada.
As Nazemi says, “This visualization is like a time map. People can see in a particular year and/or location how many stations there were.”
Because of this feature, Nazemi and Jiwa learned that the number of active climate stations across both Canada and Quebec has declined from its peak in the late 1970s and early ’80s, to rest around the same level as in the ’60s.
“Canada is experiencing the effects of climate change at two times the rate of the rest of the world,” he says. “It’s indeed concerning that the extent of data is decreasing. We really need to have these data so we can extract crucial knowledge from the past that can help us to better plan for the future.”
Meanwhile for Jiwa, the work with Nazemi has made him reconsider what he wants to do when he completes his degree.
“I enjoyed this project because of its potential impact and the broadness of the field itself,” he says. “The more I get into it, the more research seems like a viable option for me when I graduate.”
And for Nazemi, this is just a start: “We are now working on new products, aiming at bridging the gaps between environmental data, researchers and the public.”
