Chapter 21: Impact Cratering

Now You See Me...


A comet, such as that responsible for ending the age of the dinosaurs, would rank ten on the Torino Impact Hazard Scale, the high rating translating to mean certain global climactic catastrophe born from the collision, destruction capable of threatening the very future of civilisation. At a glance, it is inconceivable that fossils like that of the Woolly Mammoth seen in my picture are the few remains of the Mesozoic era left today, impossible that a comet was capable of wiping out giants like the dinosaurs.

Yet, the comet alone is not responsible for the dinosaur’s extinction; rather, it is the chain of events set into play from the moment it penetrated the Earth’s crust that is to blame. Unimaginable chemical changes to the atmosphere, cataclysmic volcanic reactions, unprecedented high winds and severe storms are only a fraction of the overall changes the climate underwent overall. Therefore, keeping this in mind, it becomes easier to understand how beasts like the dinosaurs could perish from one collision to the Earth.  It is arguably for this very reason that the Torino scale was established,  so that humanity is made capable of tracking comets and asteroids the like in order to anticipate damages born from those hazardous impacts in order to meet the danger as best possible.
