Thank you.
There are two parts to answer. There's an adaptation part and an emission reduction part.
On adaptation, we certainly have a lot of infrastructure that was designed for what we might call a stable climate. We no longer have that situation; we have a climate that is changing. So such things as sewage and drainage facilities are sometimes totally inadequate for the increase in severity and frequency of heavy precipitation that we can expect. So it's quite clear for infrastructure in central Canada.
The bigger worry, of course, is what you do about infrastructure in the north. A lot of it is built on frozen mud that is essential for the survival of many of these communities, but the mud is melting. If the ice roads can't be relied on to bring in supplies in the winter when they need them, then clearly they're going to be suffering.
So on the adaptation side you're absolutely right. On the mitigation side there's clearly a lot we can do, including enhancing the energy efficiency of transportation. There are lots of ways to do it. But the IPCC report talks about the enormous possibilities from buildings.
