Oxford University researchers have reconstructed historical rainfall (paleorainfall) measurements to assess the causes of extreme precipitation events during this key time in Earth 's history.

They used oxygen isotope data from stalagmites south of Morocco 's Atlas Mountains as historical climate archives.

The researchers link this to increased rainfall, with the 18O low at 7,000 years ago potentially leading to an additional 27cm per year of precipitation.
