Environmental politics has always played a role in Naomi Klein’s work and she has been active in the recent waves of divestment campaigns, including a critique of the green movement’s own portfolio. We can expect more with her new book, which focuses on climate politics and is due for release in September 2014, well timed to intervene in the debates surrounding the big UN talks in New York. Klein offers an alternative amongst the increasing vogue for capitalist-friendly climate discourse, though her 2011 article Capitalism vs the Climate may be showing its age. You can follow her on Twitter @NaomiAKlein.
