在过去的四十年里，加拿大被森林大火烧毁的面积有所增加，与此同时，夏季气温也在变暖。在这里，我们使用一个耦合气候模型的输出来证明，人类排放的温室气体和硫酸盐气溶胶对这种变暖做出了可检测的贡献。我们进一步表明，近几十年来，人为引起的气候变化对加拿大森林火灾烧毁的地区产生了可察觉的影响。燃烧面积的增加可能对陆地二氧化碳排放和森林生态系统产生重要影响。
The area burned by forest fires in Canada has increased over the past four decades, at the same time as summer season temperatures have warmed. Here we use output from a coupled climate model to demonstrate that human emissions of greenhouse gases and sulfate aerosol have made a detectable contribution to this warming. We further show that human-induced climate change has had a detectable influence on the area burned by forest fire in Canada over recent decades. This increase in area burned is likely to have important implications for terrestrial emissions of carbon dioxide and for forest ecosystems.
