Introductory statement: For at least five centuries, people from the region near the Qinling Mountains in central China went into Dayu Cave to retrieve water and pray. Some of them marked their visits with graffiti—bold black text against the yellow-brownish walls—that recorded the droughts that sent them to the cave’s Dragon Lake.

Thesis statement: Scientists have matched those chronicles with chemical data compiled form the cave itself and found evidence that more hard times could be ahead.

Main points:

The graffiti recorded at least 70 visits to the cave by locals.
Humans around the world have marked their visits to caves with graffiti, but these are the first known cave writings to record details about drought.
Caves themselves can reveal evidence of local climate through the formations or nonformations of stalactites and stalagmites.
Climate has a massive influence on society and our highly industrialized society will be just as impacted by drought as people were in pre-industrial society.
