It is very clear, according to the science, that we've entered the era of climate change and that we have to play both offence and defence. We have to play offence in the sense that we have to put in place everything we can to reduce, as rapidly as possible, carbon pollution in Canada and around the world. However, we also have to play defence because we've entered the era of climate change, and there are impacts being felt across the world and, certainly, in Canada.
You were talking about the forest fires. I was in British Columbia last week talking to members of the B.C. government, who told me that the evacuation in Fort Nelson two weekends ago was the earliest evacuation in the history of the province. We've never had that happen so early in the year, and we've also seen other evacuation orders across the country.
That's why we worked with all provinces and territories, indigenous nations, municipalities, the private sector and insurance companies to develop the first-ever national adaptation strategy to help better protect our communities and Canadians, whether from wildfires, floods or the intense heat waves we're seeing more and more.
However, it's not just us looking into this. Canada is hosting the NATO Climate Change and Security Centre of Excellence in Montreal. It's obviously an issue, I would argue, for most Canadians and for most parliamentarians in the House of Commons, but it's also an international issue, so much so that it's now viewed as a security issue by the U.S. government, NATO and many others.
Since 2015, we've invested about $10 billion in disaster relief and in different measures to help Canadians be better prepared to face the impacts of climate change. We understand we will need to do more. For every dollar we invest in being better prepared, we save $15.
