Poor Andrew Coyne can’t tell the difference between obligatory political lip service and a genuine issue.
If there is one thing on which all federal parties and all national political leaders are agreed, it is that they “believe the science” on climate change. They believe that the earth is warming, they believe its effects are on balance malign, and they believe it is caused by human activity. As such they believe it can and should be mitigated by human action, namely by reducing greenhouse gas emissions.
There isn’t any dispute between them over this. Every party agrees there’s a problem, every party agrees on its cause, and every party agrees on its solution. And no party (or none with any chance of governing) has anything resembling a serious policy to achieve it.
