Re: How serious is a 1st degree burn?

When you touch something very hot, it rapidly heats up several layers of skin. When you remove your skin from the heat source, the skin starts cooling back down, but in room temperature air that takes quite a while. It happens much faster in running water, especially cold water. It really is as simp...

The "cocaine mummies" were moved many times over the course of a century. To be honest, it would be surprising if some cocaine weren't found by people looking hard enough. That's kind of the nature of cocaine dust.

Yeah idk what the core has to do with anything. It might be an interesting thing to think about, but it is not related to climate. More importantly, it has not changed significantly in the past 22,000 years. It has cooled by perhaps 1 or 2 mK and most likely grown by a few meters.
