This Changes Everything (book)

This Changes Everything: Capitalism vs. the Climate is Naomi Klein's fourth book; it was published in 2014 by Simon & Schuster. Klein argues that the climate crisis cannot be addressed in the current era of neoliberal market fundamentalism, which encourages profligate consumption and has resulted in mega-mergers and trade agreements hostile to the health of the environment.

Klein spent five years writing the book, which debuted on the New York Times bestseller list at number five on 5 October 2014. The book is credited with popularising the anti-extractivist Blockadia movement.
