Chart has baseline at ~1995. They say we reached 200 zettajoules around 2019.
200 zettajoules => 2.0e23 J * 4.184 J/cal => 8.36e+23 calories
They say this is the energy absorbed by top 2000 meters of the oceans. There are 84.8 million sq km of ocean.
2000m * 84.8e6 => 1.69e20 liters of water.
1000 calorie to warm 1L of water by 1 deg C.
1.69e20 L / 8.36e23 cal => warmed by 0.2 deg C since 1995.
- idealmedtech 5y agoThat's alarmingly fast.
- glial 5y agoIf my calculations are correct, that's the equivalent of 52 billion Hiroshima bombs.
- MatteoFrigo 5y agoDon't you want to divide J by (J/cal) to get cal (as opposed to multiply)? 2.0e23J = 4.78e+22 cal
