Dinosaurs were roasted to death by asteroid dust cloud
New research suggests the Chicxulub asteroid impact triggered a global firestorm that may have caused the rapid extinction of the dinosaurs.
The obvious questions
What caused the global firestorm?
New research indicates that lingering dust from the Chicxulub asteroid impact turned falling debris into a thermal force that ignited global fires.
How long did the extinction event take?
According to reports in Popular Science, the new study suggests that the extinction of the dinosaurs took place within hours.
Does this replace the theory of an 'impact winter'?
Current coverage focuses on the evidence of an intense thermal event, though it does not explicitly declare the end of other extinction theories.
The story so far
Findings published by Phys.org, Popular Science, New Scientist, and The Telegraph indicate that instead of a prolonged winter, the immediate aftermath involved a catastrophic surge in global temperatures. Science outlets detail how lingering asteroid dust likely acted as a catalyst for a global firestorm. The resulting thermal radiation suggests that the extinction event occurred within hours rather than years.
This hypothesis moves away from traditional models of a cooling planet, focusing instead on a heating event that effectively incinerated surface life. Research teams are currently analyzing the behavior of fine-grained asteroid debris in the atmosphere. Because the extent of these thermal effects remains under ongoing study, scientists are working to determine the precise atmospheric density required to sustain such a widespread firestorm.
Coverage does not yet specify how this data will shift geological dating models for the Cretaceous-Paleogene boundary.
