Critics are failing the science test.

The problem with activist editorial writers is that all they know about “the science” is what they read in the funny papers. And they have developed a facility for ignoring inconvenient political facts.

Robert Hicks writes that heat pumps are a “renewable energy solution.” No, they’re not; they run off electricity, however generated. They’re very poor for heating homes in Canadian winters, especially the winter cold that is experienced in Canada’s prairie provinces.

The claim that rising CO2 will cause global temperature to rise by 1.5C is also false. Global temperature may well rise above 1.5, but it won’t be due to CO2. This is the physics: if CO2 is doubled from 400 to 800 ppm, it will increase “greenhouse forcing” by 3.7 W/m2, which results in a temperature increase of 0.7C. These are IPCC’s own figures. To get to 1.5C, greenhouse forcing has to rise by 9 W/m2, which is impossible by CO2.

Lastly, politics. Asia accounts for 60 percent of global CO2 emissions; Canada, only 1.5 percent. Canada isn’t the problem, and can’t be the solution.  Asian countries aren’t playing the CO2 reduction game, so if you think rising CO2 will bring about global doom, prepare yourself accordingly: there is, apparently, no place to hide.
