I was curious on the math for all this. Surface area of earth = 510,064,472 km2 70 percent water = 357,045,130 km2 2.2mm = 0.0000022 km volume = 785.499 km3

I was curious on the math for all this.
Surface area of earth = 510,064,472 km2
70 percent water = 357,045,130 km2
2.2mm = 0.0000022 km
volume = 785.499 km3
GIS area 1,710,000 km2
div vol by area = 459.3 mm
melting 1kg of ice from 0C = 333.55kJ
density of ice = 919kg/m3
785,499,000,000 m3 x 333.55 =
262,003,191,450,000 kJ
1J/s = 1w
2 months = 5,184,000s
= 50,540,739 kJ/s
= 50.540 GJ/s
= 181,944 GWh
making it the 24th largest electricity producer in the world (if it were all electricity).
That's pretty incredible!
- misja111 7y agoI got inspired by your calculation to fact check the article's claim of the 2.2mm see level rise. They apparently base this on the reported melting of 600 Billion tons of ice as stated in the article. 600 Billion (metric?) ton = 600000 Billion kg (or liter water) = 600 km3 This doesn't quite add up. I wonder where they got the 2.2 mm from ..
