Evidence suggests that the lost river flowed through the central Thar Desert near Bikaner.
Geographically, the desert is located partly in Rajasthan, with its other part stretching towards eastern Pakistan in Sindh.
Every year, fluctuations are observed in the #ozone hole due to variation in stratospheric temperatures—the second layer of Earth’s atmosphere. As per recent observations, this year’s ozone hole is recorded to be one of the largest & deepest, as compared to the last 15 years.
However, despite the alarming changes, not many scientists are concerned about any major impacts on #Earth, mainly because it appears to be just a seasonal phenomenon.
