Category 7

I am not sure when it is on but they’ve been advertising a show called Category 7: The end of the world. They show a clip of Paris being destroyed and everything. Ok here is the deal it is physically impossible to get a hurricane above Cat 5. Why? Because reach Cat 5 just to reach Cat 5 requires near prefect conditions, then once they do they can’t keep up with their own energy needs so they weaken and go back to a Cat 4 or 3. Now if it was possible for a storm to keep growing once it reached Cat 5 it would be so large that it would pull its self apart because to keep the core spinning would mean the outside spiral arms would have to move so fast they would shear off.
If we pretend that a hurricane could reach Cat 7 once it touches land it starts to lose energy since the energy is taken from the ocean and to get Paris would require a big piece to be over land (Portugal, Spain, the rest of France, North Africa, little things.) If we keep pretending that could happen then the storm would have to get unhindered above the 48th parallel which on the other side of the Atlantic is Newfoundland, yes like Vikings and reindeer. But past about Virginia there isn’t enough energy in the ocean to keep the storm going. Now if we keepppp pretending that a Cat 7 hurricane could do all of these things, to reach Paris would require the storm to go against the earth rotation and that my friends in impossible, and if it were possible we would have bigger problems cause one of the few things that could actually destroy the earth much like it destroys car transmissions is shifting into reverse going full speed. The sudden reversal of the earth’s rotation would shatter the crust and cause massive deformation of the semi-liquid mantle which would spurt out and maybe calve us a new moon. Unfortunately no one would survive to see the double moon rise, so the view would be largely wasted. You need not worry; to reverse the earth’s rotation would take an unimaginable amount of energy. You also need not worry about a Category 7 hurricane either.
But if you need to worry about something there is a caldera volcano (a so called supervolcano) under Yellowstone Park, that when it erupts will blanket most the Midwest in several meters of ash, trigger a short lived nuclear winter, cause a sever drop in global temperature that could last a decade and the eruption is several thousand years overdue. I wouldn’t panic yet since in geological time even a couple thousand years is a blink of an eye, so the average human’s life time isn’t even worth measuring.
