This will be interesting here in Australia. We've had quite a lot of major flood events on the east coast in the past year. Thousands of people should move as it is predictable that it will happen again in the next 20 years.

So completely within our own country we will have climate change related movements of people.

We also have a lot of landspace for our population size and quite a few neighbouring pacific island nations that may need a place to go.

And to offset China's assertions in the Pacific, Australia is doing all it can right now to be seen as the "helpful neighbour"...

I expect to see more in this space over the next 40 years.
