Systematic use of coal as a fuel source found at Bronze Age dig site

Prior research has shown that use of coal as a fuel source goes back many thousands of years, and its systematic use approximately 2,500 years. In this new effort, the researchers found evidence of systematic use approximately 3,700 years ago.

...two civilizations lived there nearly 1,000 years apart. The bottom level, the oldest, has been studied by other groups. The team on this new effort focused their attention on the layer that preserved evidence of habitation between 3,000 to 3,700 years ago—during the Bronze Age.

In addition to many artifacts, dig teams have unearthed coal from ancient fireplaces, storage pits, homes, smelting furnaces and near tool caches. Such a wide variety of sites, the researchers suggest, indicates that the use of coal was well established and it was used in many ways, including cooking food, heating homes, smelting metal and making weapons and tools. Or put another way, it suggests systematic coal use, nearly 1,000 years earlier than any previously known example.

The research team notes that in addition to the use of coal, the upper level of the dig site showed that much had been learned over the prior 1,000 years, such as growing crops, domestication of animals and the development of bronze processing. They also state that it was likely that the use of coal was adopted as wood became scarcer in the area. They also suggest that replacing wood with coal was likely a natural progression, as there was plenty of coal at or near the surface in the area, and the idea of using it as a fuel source likely was not much of a leap—coal has been known to combust naturally when exposed to the sun on a hot day.

Proof right there that they started climate change.

I saw it in WV at a coal yard. A pile was smoldering for no reason

What difference does it make? They’re only showing that humans were using coal as a fuel earlier than previously believed. Fossil fuels have been critical to the survival of the human race, just as God planned it.

“What difference does it make?”

It doesn’t make any difference. I simply get tired of people posting things from unknown places, thinking that wherever they are is the center of the universe, then the other readers have no idea where a particular place is.
