ReedRothchild’s review published on Letterboxd:
Hot Air is a chronicle of New Zealand's political response to climate change through the nineties and noughties. While it makes no secret of its agenda, it is never partisan (National's Simon Upton comes across best, for example) and it supports itself with sound science. As a result, it is extremely comprehensive, academic and informative. People are interviewed from both sides of the debate but it never really gives much thought to arguments against New Zealand taking action.
