I came across an old article recently, about the collapse of the Harappan civilization. Here's the paper it is based on- https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3387054/
I found this to be the most compelling explanation so far, because the evidence seems to back it up. However, I'm surprised because I've barely ever heard or seen this article/paper being discussed anywhere (or maybe I'm bad at finding such discussions).
It might sound like an opinion-based question because I want to know what people think about this theory, but I also want to know if there is any more data that supports or strongly refutes this claim.
EDIT- Explaining the claim (not sure if claim is the right word because there's quite a lot of evidence)- The claim is that climate change and drought forced the IVC people (barring few small farming communities) to move eastward towards the Ganges. And this is backed by the fact that a large number of IVC sites of the late-Harappan era were found closer to the Ganges.
I wanted to know how widely is this accepted, or are there any papers that refute this?
