Climate change is the greatest challenge of the age and yet it is also one of the most disputed. Fierce disagreement still exists over the best way to tackle the problem and, indeed, even about whether it should be tackled at all. Viewed as problematic, however, such disagreement is often dismissed as irrational, irrelevant or unethical and is thus hidden behind an artifice of consensus. Drawing on radical democratic theory shows that political conflict and disagreement doesn't hinder collective action and should be revealed and revered, for democratic differences are actually necessary to tackle the problem of climate change. This original book is an important read for researchers, students, policy makers and anyone concerned about the current (lack of) politics of climate change.
