- rainworld 3y agoIndeed we are 2–3 orders of magnitude away from the point where our energy output itself non-negligibly, globally heats the earth. And if we kept growing, an incandescent Earth would not be too far off. There are hard limits.
- abecedarius 3y agoCurious: for the latter I get 7e21 J, using Wikipedia's normal-insolation figure of 947 W and its Earth albedo of 0.3. That's an order of magnitude greater. I'm probably missing something, do you have a source? (Of course my figure would only increase the difference you're pointing out.)
