Here’s a review of a superb book which pertains to that https://www.theguardian.com/books/2017/sep/10/american-war-omar-el-akkad-review

It’s called American War and it’s by Omar el Akkad. The book is an excellent read and requires no stretch of the imagination.

“Set in the US some 60 years hence, Omar El Akkad’s dystopian debut imagines civil war breaking out after a group of southern states revolt against a fossil-fuel ban imposed when extreme flooding leaves Florida under water.” (beginning of the review in the Guardian)
