Over the past few years, there has been a lot of discussion about the phenomenon of climate change, the negative impact of which on the planet is quite recognizable. Climate change now seems to be gradually destroying the most ancient and valuable cave paintings that are an important source for research into the early life of our ancestors.
New research by scientists at Griffith University in Australia shows that global warming is slowly destroying ancient paintings of limestone caves south of the Indonesian island of Sulawesi, some 20,000 to 40,000 years ago. These paintings are among the first cave paintings discovered in the world.
To find the source of the problem, the researchers analyzed eleven different cave paintings using microscopes and other techniques, including chemical analysis and crystal identification. They found that salt crystals were forming on the cave walls, causing the rock to break and flake off, destroying the paintings.
Researchers state in their research:
"The tropics are home to some of the oldest known stone arts that are weathering at an alarming rate. By doing this research, we have shown that these stone art paintings are rapidly deteriorating in recent decades, and climate-influenced salts are responsible for increasing peeling from the surface of limestone caves that house 45,000 to 20,000-year-old paintings.
Therefore, if no action is taken in response to this natural disaster, we may lose the most important parts of our history. Unfortunately, we now know little about the methods of dealing with this phenomenon and its negative consequences, as much as the methods of dealing with climate change.
