That's a great question.
I think it's critically important.
When we're talking about climate change, it's a tragedy of common issues. Unless all the countries work co-operatively together, we're just not going to be able to deal with it effectively. The future threats associated with climate change are, in my opinion, just going to be simply catastrophic eventually.
It is absolutely critical that eventually we work together as partners to try to solve these things down the road, so it cannot be more important that we have some sort of global co-operation in terms of dealing with it in the future.
