A new study identifies the impact of major wildfires and volcanic eruptions on global atmospheric temperatures, and underscores the importance of human activities in causing tropospheric warming. Researchers used advanced climate modeling to isolate the 'fingerprints' of natural events. While volcanic eruptions typically lead to stratospheric warming and tropospheric cooling, the study found that the increasing frequency and intensity of wildfires are creating significant atmospheric perturbations. However, the data confirms that the long-term warming trend in the lower atmosphere is inextricably linked to human-induced greenhouse gas emissions.
