Can't be having taxpayers foot that bill.

And government policies favouring coal and oil are more directly responsible than anything else. If the US government had set strict emissions standards and MPG standards and imposed higher taxes on fossil fuels 25 years ago? The situation with regard to climate change might be somewhat better than it is now.

And the Koch bros should be court ordered to live right on top of their Keystone Pipeline of Demarcation.

for not blocking the problem in the past.

Since carbon dioxide added to the atmosphere can stay there for centuries, historical emissions are just as important – or even more important – than current emissions. The tricky question of historical responsibility is one of the key tensions in the process of negotiating a global climate deal. The following figures from the World Resources Institute show the top 10 nations as measured by their cumulative emissions between 1850 and 2007. The US tops the list by a wide margin – though Chinese emissions have risen significantly since these data were assembled.

1. US: 339,174 MT or 28.8%
2. China: 105,915 MT or 9.0%
3. Russia: 94,679 MT or 8.0%
4. Germany: 81,194.5 MT or 6.9%
5. UK: 68,763 MT or 5.8%
6. Japan: 45,629 MT or 3.87%
7. France: 32,667 MT or 2.77%
8. India: 28,824 MT or 2.44%
9. Canada: 25,716 MT or 2.2%
10. Ukraine: 25,431 MT or 2.2%

I would hope that international environmental treaties would set up multilateral institutions that could hear and rule on such cases.

Energy companies have a lot of clout in national governments, so having lawsuits like this tried in national (American, Chinese, etc.) courts might not be a fair way to see these poor farmers get fair compensation.

Even here in the U.S.A..

Mechanisms need to be set up for abandoning and recycling properties threatened by the sea before they ground up into garbage by storm surges and such.

Most likely we won't do anything and eventually the climate refugee problems will become overwhelming.
