Triassic Period Saw Millennia of European Fires During Global Warming
Around 201 million years ago, at the end of the Triassic period, a mass extinction event coincided with intense global warming. This warming, estimated at 5 to 10 degrees Celsius, was driven by massive carbon dioxide emissions resulting from volcanic activity. This volcanism was itself a consequence of the supercontinent Pangea breaking apart. The extreme heat caused widespread collapse of tree-dominated ecosystems. These disturbed landscapes were then overtaken by ferns, which created vast fern savannahs across regions now known as Northwest Europe. This period highlights a significant ecological shift triggered by rapid climate change.
The end-Triassic extinction event serves as a stark historical precedent for the profound ecological disruption that can accompany rapid, CO2-driven global warming. The collapse of established vegetation and subsequent colonization by opportunistic species like ferns illustrate the fragility of ecosystems under severe climate stress. Understanding these past transitions, particularly the long duration of the warming and its impact on landscape composition, offers critical insights into potential future ecological responses. This historical event underscores the importance of considering the long-term, systemic consequences of greenhouse gas emissions on biodiversity and planetary habitability.
