It is predicted that under a warming climate, wildfire frequency will likely increase. The increase in fire activity is hypothesized as a likely consequence of increased atmospheric CO₂-driven climate warming having the potential to influence fire weather and increase ignition probability.

Periods of greenhouse gas-induced global warming have occurred many times in Earth's history, evidenced as episodes of perturbation in climate related proxies within the rock record. Coupled with an extensive record of wildfire in the fossil record dating back ~400 million years, the geological record thus provides an opportunity to aid in our understanding of how past periods of climate change may have altered wildfire activity. This review presents a collation of published records of inferred wildfire activity across some of these episodes of major greenhouse gas-induced warming events in Earth's past, to assess whether a link exists between periods of greenhouse gas-induced climate warming and the increased likelihood of wildfire activity. Within this review, it is concluded that there is substantial evidence of increased combustion products, taken to be indicative of increased wildfire activity, occurring in tandem with periods of global climate changes in Earth's past. These patterns of climate-driven wildfire changes may therefore provide information for our future predictions of wildfire occurrence on a warming planet.

预计在气候变暖的情况下，野火发生的频率可能会增加。火灾活动的增加被假设为大气 CO ₂驱动的气候变暖增加的可能结果，具有影响火灾天气和增加着火概率的潜力。

温室气体引起的全球变暖在地球历史上发生过多次，证据是岩石记录中与气候相关的代理的扰动事件。再加上可追溯到约 4 亿年前的化石记录中广泛的野火记录，地质记录因此提供了一个机会来帮助我们了解过去的气候变化时期可能如何改变了野火活动。这篇综述整理了地球过去主要温室气体引起的变暖事件的一些事件中推断的野火活动的已发表记录，以评估温室气体引起的气候变暖时期与野火可能性增加之间是否存在联系。活动。在这次审查中，得出的结论是，有大量证据表明燃烧产物增加，这表明野火活动增加，与地球过去的全球气候变化时期同时发生。因此，这些气候驱动的野火变化模式可能为我们未来对变暖星球上野火发生的预测提供信息。
