worth of energy per second over 2013.
Rising from the 4 bombs per second long term average.

So much for the supposed 'pause' in global warming.
That sounds like a self limiting expression of heat. We know, for instance, the sun did not all of a sudden put out 3X the energy it has always given us, 1355 odd watts per square meter on top of the atmosphere, that hasn't all of a sudden gone to 5000 W/M^2. So the heat is from some kind of heat battery and will run itself out, seems to me anyway.
What does it work out to in Joules what a Hiroshima bomb produced? And for how many seconds? When you say 10,000 tons of TNT equivalent, what is that in terms of watt hours or Joules?
My guess is the TOTAL amount of energy given by the sun 24/7 is a LOT more than 12 A bombs per second.
Just as a rough estimate, suppose we call the Earth 10,000 Km^2. 1E7 Km^2. That would be roughly the surface area that can take energy from the sun. So lets round off the 1355 to 1000 w/M^2. I imagine this estimate would be a bit low but close enough for government work, eh🙂 So that would be 1E7 Km^2 *1E6 meters^2 * 1000 sounds like about 1E16 Joules/second. What's that, about 10,000 Terawatts heating up the oceans and atmosphere and sand and rocks and trees and such?
Einstein said 1 Kg of matter contains the energy of a 100 watt light bulb that would last 30,000,000 years.
So the inverse, 30 megawatts for 100 years or 300 MW for 10 years or 3000 MW for 1 year.
Now fission is what, 1/10th of a percent of that in terms of efficiency compared to total conversion, anti matter/matter reaction?
Something like that. So 1 Kg of fissionable material could do us 3 megawatts for a year. Not sure how much actual fissionable stuff there was in the hiroshima bombs but it must have been only a few kg.
Now that bomb used up all that energy in say, 1 second. So that would have been 33 million seconds times 3 megawatt/year would = about 100 Terawatt/seconds, it looks like, roughly speaking.
So 12 of those suckers would be something like 1200 terawatt/seconds.
I don't know. That seems to put the energy involved at something like one tenth the entire output of the sun to what hits the Earth.
But it CAN'T add up to 3 times the sun's total output.
Not sure WHAT that means.
