I'm not going to be one of those people who say humans didn't play a role, but seriously. Good luck fixing this.
How much energy is needed to raise the world's ocean temperatures by 0.1F
TLDR#
It would take 3.00e+23 joules to raise the temperature by 0.1F, or 3.42 trillion "Fat Man" Nukes. Or 239 Billion of our new Modern Minuteman III nukes.
Calcs to raise ocean temps 0.1F
mass_oceans = 1.35e21 # in kg
specific_heat_water = 4000 # in J/(kgC)
temperature_change = 0.0556 # in C (0.1F to C)
# Energy calculation
energy_required = mass_oceans * specific_heat_water * temperature_change
energy_required
Result
3.00e+23 joules
How many "Fat Man" nukes would that take?
# Energy of one "Fat Man" bomb (in joules)
kiloton_to_joules = 4.184e9 # in joules per kiloton
fatman_yield = 21 # in kilotons
# Energy of one Fat Man bomb
energy_fatman = fatman_yield * kiloton_to_joules
# Number of Fat Man bombs needed
num_bombs = energy_required / energy_fatman
num_bombs
Result
3.42 Trillion Fat Man Nukes
