Here is this.

>> If the entire population of the Earth is drowned in Baikal, the lake level will rise only 4 centimeters.

The simplest Nerd calculations (if you take the average human weight for 80kg, generalizing the lean Chinese with the fat American, and the average density for 0.95 for the same reason) show that 7 billion. People with an average volume of 0.076 m3 will give us 532 million m3 of volume, which at the area of 31722 million m2 will give us a level increase of 0.0167 m, that is. See also 1.67 And that’s unless you count on the shore. A little will correct the situation with the stones to which the population will be bound. Probably a millimeter. But 4 cm will not get any. So don’t go here with unchecked facts.
