An interesting calculation has been made regarding Global Warming. The question arises how much influence do people have on the Global Temperature.

SpecificallyIf every persons alive put 1 Hiroshima Sized Bomb into the Pacific Ocean, how much would it increase the temperature of this ocean?

What is your guess?
1 degree? 10 degrees? 100 degrees? More?

Here are the calculations:

Number of people alive on Earth
7 Billion

Pacific Ocean Size:
7.0902*10^20 KG

Energy from 1 Hiroshima sized bomb
63 * 10^12 Joules

Joules needs to raise 1 KG of water 1 degree of temperature C
4186 joules

Resulting Temperature increase
.0148c
only about 1/7 of a degree
(and that's just the Pacific Ocean, the world wide increase would be much smaller)

An interesting calculation showing how difficult it is for man to increase the world's temperature.
