What a fantastic documentary topic. Likely to be one of many in the not too distant future.

Probably a question more for Michael - I was really taken my Gwynn’s Dyer’s book “Climate Wars” many years ago. But this one (and many others) are largely northern hemisphere focused. As a fellow Aussie, how do you see scenarios playing out for Australia? Is there such a thing as ‘Life Boat Australia’ in the future?

Thanks for the question min0nim. I agree, much of the focus has been on impacts across the northern hemisphere. Age of Consequences in this genre is also an example, documentary wise. And, on your point, I too have read Gwynn Dyer's book. In regards to Australia, lets take some top line impacts: (1) water security. It may not seem like it now, but signficant drying out (decades scales) across South East and West since the 1970s. Many cities are moving to desalination ("manufactured" water) but you cannot do desal across the food bowl of the Murray Darling basin! 2) Extreme weather - fires, floods, drought. Take your pick here. 2019/20 bushfires were just devastating to communities, wildlife, infrastructure and so on. A sign of things to come right there. 3) Broader and wider impacts on large scale systems like Great Barrier Reef (coral bleaching events and so on), kelp-forest 'kills', migration of fish (and other) species. These have both economic, but also cultural impacts. 4) Critical infrastructure and resilience. As stresses increase, the capacity for communities to cope is really challenges (as is the ability for governments to respond).
