Obama: U.S. & Canada ‘Responsible for a Lot of the Carbon Pollution’ Warming Planet

"And with respect to big ideas. Look, to some degree you don't fix what's not broken, and the relationship is extraordinary and doesn't, I don't think, need some set of revolutionary concepts. What it does require is not taking the relationship for granted. It does require steady effort. And perhaps most importantly, it requires because we have so much in common, that we recognize on the big looming issues on the horizon it is vital for us to work together because the more aligned we are, the more we can shape the international agenda to meet these challenges. 

Climate change is such an example. This is going to be a big problem for everybody. There are countries that are going to be hit worse by it. In some ways Canada and the United States as wealthier countries can probably adapt and manage better. On the other hand, we're also those responsible for a lot of the carbon pollution that is causing climate change. If we don't agree, if we're not aggressive, if we are not farsighted, if we don't pool our resources around the research and development and clean energy agenda that's required to solve this problem, then other countries won't step up and it won't get solved."
