The Australian regularly shows its contempt for science, scientists and the scientific method, titling an article “Respect the science and don’t call CO2 a pollutant” is more than little hypocritical. You might think from the title that the author, Ziggy Switkowski, presents some sort of scientific argument why CO2 is not a pollutant, but he doesn’t. The closest he comes is this:
Many cold regions in the northern hemisphere welcome global warming. Think of Scotland, parts of Scandinavia, Russia, Canada. To them, increasing CO2 is not a problem. Is it possible for CO2 to be a pollutant in the southern hemisphere but beneficial in large parts of the north? What previously unknown principle of chemistry is at work here, which changes the character of a molecule depending on location?
Let’s see: ground-level ozone harms people’s lungs, while ozone in the stratosphere protects us from UV radiation. Is Switkowski going to object to references to ozone pollution as well?
CO2 is a pollutant because increasing CO2 in the atmosphere harms the environment. And that’s according to one Ziggy Switkowski in an article published in The Australian (my emphasis):
Deepwater Horizon dramatically reveals the hazards of oil exploration in hostile environments. But it also hints at the magnitude of the global climate challenge: the enormous volume of fuel required by our energy hungry society and the mass of emissions that is produced. We may be devastated by the environmental damage of a deep-sea oil spill, but our atmospheric pollution is longer lasting and more consequential.
