The challenge follows years of friction between the society and global climate advocates. The Calgary group, which maintains a network of over 2,000 scientists and scholars, argues that the current global push toward Net Zero is based on outdated and implausible climate scenarios. Their critique centers on the RCP 8.5 model, a scenario previously used to justify aggressive policy shifts that many in the scientific community now categorize as extreme and unrealistic.

Central to this opposition is the work of organizations like Clintel, which counts former Czech president Vaclav Klaus as its president. Through initiatives like Mathew Embry’s documentary, "Global Warning," the society highlights concerns regarding the economic impact of green policies, specifically citing the risks of energy poverty and deindustrialization. These skeptics contend that carbon dioxide is not the primary driver of climate change, pointing instead to solar activity. As the group advocates for a reassessment of Canada’s climate spending—estimated at $476 billion between 2020 and 2030—they argue that the perceived climate emergency has concluded, necessitating a pivot toward more pragmatic national priorities.
