Since McKenna is making policy on the advice of climate scientists both inside the federal government (ECCC, NRCan, DFO) and outside it, and sticking to the mainstream consensus on climate change held by the vast majority of climate scientists and every single international scientific body that has taken a position on the topic, how is that relevant? She's a cabinet minister smart enough to listen to experts.

I suspect that, plus the fact she's been effective in her role, is why McKenna is one of the main targets of climate 'skeptics' and those opposed to a shift to renewable energy.
