Some systems had only hours to go kerplop. The New York subways would be flooded within four days. The power grid would shut down and, in some cases, start combusting within a week.
House dogs and most other pets would not survive. Cats, on the other hand, would do just fine. Those not quick enough to catch mice and squirrels would just switch to moles and birds.
Within 40 years, windows would mostly fall out of buildings. Glass is a liquid, after all. Within a century, highways and streets would be overgrown with grass. Undulates would thrive as would their predators.
After 10,000 years, only a handful of man made edifices would even be recognizable, including Mount Rushmore (minus the noses) and pyramids of Egypt.
Biggest news-- none of the real scientists or computer models would or could predict climate changes in the earth because such changes were largely outside the control of man. Interesting stuff.
“Glass is a liquid, after all.”
No, it’s not. If it was there wouldn’t be well-shaped glassware thousands of years old. The “old windows are thicker at bottom ‘cuz thy flowed” is BS - panes were made and installed that way back when.
This is the info I keep finding but rarely with attribution just a statement saying power grid would last no more than a week without supervision and even less if say a lightning strike took out part of the grid in a large urban area. A heavy draw to replace the downed plant would cause demand to shoot up on the remaining power generation plants and cause a cascade effect like happened a few years back.
