'A Canadian economist has an idea to tackle global warming so simple, it’s stunning no one has thought of it before. Ross McKitrick, Professor of Economics at the University of Guelph in Ontario, an IPCC expert reviewer and one of its leading critics, proposes a carbon tax with the rate tied to climate response...McKitrick’s plan replaces the piecemeal regulation and taxes, which are arbitrary and random (ranging from patio heater bans to a “carbon floor price”) with a tax linked to the temperature of the troposphere. According to IPCC scientists this is the “fingerprint” of greenhouse gas-induced global warming and the most rapid indicator of climate change. If temperatures go up, then so does the tax. With the introduction of tradeable emissions certifications alongside the new, evidence-based tax then powerful incentives are in place to be right. “Nobody will benefit from using false or exaggerated science,' McKitrick said. 'Sceptics who do not believe in global warming will not expect the tax to go up, and might even expect it to go down. Those convinced we are in for rapid warming will expect the tax to rise quickly in the years ahead,' McKitrick explains in a paper outlining the idea.'
