# Human body water storage effects on weather patterns

There are 7.614 billion humans and counting. On average a human being consists of 60% water. With that water being locked away from natural circulation for an average of 80 years. Are there any adverse effects this could have on global weather patterns?

• You assume that if the water wasn't "locked away" in human bodies that it would not be locked away in some other place instead. Why? – Solomon Slow Apr 11 '18 at 14:19
• Total volume of all of the human bodies on Earth is less than one billionth of the total volume of all of the world's oceans. – Solomon Slow Apr 11 '18 at 14:20

Second, the total mass of all human water is on the order of ($7.2\times 10^9$ people)(62 kg)(65% water) =$2.9\times 10^{11}$ kg. This is a bit more than the water stored in the London storage reservoirs (0.2 km$^3$), nothing significant globally when you consider real lakes, rivers and seas.
