Climate change plays a role in the increased intensification and frequency of bushfire seasons, although it promotes hot and dry conditions rather than directly causing fires. Prompted by the severe fire season in late 2019 and early 2020 in southeast Australia, this Commentary notes the complexity of the causal chain leading to such events, and focuses on the importance of ignition sources and fuel supply. Understanding these causal elements requires different research methods and data from the time‐series analyses that underpin identification of climatic influences. Interventions that can mitigate future fire risk and impact may need to focus more on ignition and fuel rather than on climate change; but they are likely to be politically, practically and financially difficult to implement.

丛林大火–气候，人员和政策

气候变化在森林大火季节的加剧和频率增加中起着一定作用，尽管它促进了炎热和干燥的天气，而不是直接引起火灾。该评论在2019年底和2020年初澳大利亚东南部严重的火灾季节的提示下，指出导致此类事件的因果链非常复杂，并着重于点火源和燃料供应的重要性。要了解这些因果关系，就需要采用不同的研究方法和时间序列分析中的数据，这些数据和方法有助于确定气候影响。可以减轻未来火灾风险和影响的干预措施可能需要更多地关注点火和燃料，而不是气候变化；但它们可能在政治，实践和财务上难以实施。
