And people thought I was kidding when I wondered a few years ago when we would have to face the problem of not even being able to drive due to melting tires from the heat.
The melting point of rubber tires is around 371°C or 700°F
They soften much earlier, though. And there's also the friction of moving against the road.
We can change the rubber formulation so the Tg shifts up or down. This is actually part of the difference in winter and summer tires.
They start to lose integrity around 200⁰C or 390⁰F... we'll be dead long before our tires randomly soften to the poi t rhey deform.
But you're right that friction under even slightly higher heat means they'll wear out significantly quicker. Drivers might need to change them every 1-2 years instead of 3-5, as a hypothetical.
I live in the Phoenix area. Every summer, as it starts to heat up (so like april...) you start seeing the tire debris everywhere, and the higher frequency of cars pulled over with flat tires... Heat is absolutely a factor in premature tire failure, whether or not the rubber is literally melting.
I mean of course some people don't change their tires when they're supposed to, or continue driving on flat tires to get to move their vehicle from the place it originally went flat. So sure when not being used as designed, of course there is a bias towards rubber tearing in the triple digits instead. If you're not an idiot driving on safety hazards it's extremely unlikely.
crop failure will be a big issue. cant grow corn or apples indoors. Hope yall like... lettuce.
Lettuce is a luxury food with very little nutrition and high water requirements...
Chances are good that the majority won't retain access to it for very long really since it will make the most sense to grow something more efficient.
Potatoes. You don't need a lot of light and they grow from the sprouts of old potatoes. They do need some water though. Same with other root vegetables like carrots and sweet potatoes. But I've never managed to get a sweet potato to grow. Carrots and potatoes and tomatoes grow good in the fall and winter in az. Now I'm just trying to figure out what to grow to can for the summer months.
