I laughed at the last two bullet points of the intro to the article:
They now believe the civilisation is around 8,000 years old,
and,
It is thought climate change may not have destroyed the civilisation
Sooo... the civilization dates to about 6,000 BC and climate change didn’t destroy it.
Ahem, if 40 straight days and nights of rain resulting in a big flood isn’t climate change, what is?
Actually the article states: “One theory, which emerged in 2012, is that climate change led to the collapse of the ancient Indus civiliSation more than 4,000 years ago.” If the 2 mile wide bolide crater found in the Iraq Marshes was a little more than 4,000 years old, then being in the path of the prevailing wind, the Indus Valley could have suffered. Also, I wonder if that meteor strike could have generated a significant tsunami, and has anyone looked for such evidence?
