The UN official probably thinks Katrina was a result of "climate change" - nothing to do with building a major city on flood plains... and what about the positive externalities of "climate change" (none, they are all negative and anyone who says otherwise is a paid big oil shill). "Climate change" has been hijacked by career activists who approach science like religious zealots. Just look at Al Gore's inconvenient truth - his models are an embarrassment to science and have been completely discounted but he was still a keynote speaker in Paris. And what about the hockey stick graph on temperatures, well that didn't come true so we call it climate change instead of global warming. A UN bureaucrat looking for more authority under the guise of saving the earth, pretending to subscribe to a higher moral authority the rest of us average plebs don't understand - especially those in Ontario who should suck it up instead of whining over their power bills - think of the children!
