What limited hazard reduction burning? Climate change.

Summary:
Between making calls not to politicise the bushfire disaster, Barnaby Joyce and others have been busy denouncing the Greens, who allegedly prevented hazard reduction burning. This isn’t actually true: The rate of burning in NSW has more than doubled. But there is one factor that has clearly limited hazard reduction burning. Because of the increased frequency of hot, windy days, even in winter, the window of time in which burning can be undertaken without the risk of accidentally starting fires has been narrowing. Here’s an example from August 2017, with authorities calling on landholders to limit burning off whenever possible, and noting that a number of hazard reduction burns have already escaped.
