It’s interesting that you touch on energy — temperature is a measure of the energy of a system, but most people don’t think of it in those terms.
If you consider how much energy it takes to raise the temperature of your living room by 4C (about 840J per m3), and then extrapolate that to the entire planet, it’s a phenomenal amount of energy, incomprehensibly vast. Then, consider that the oceans, with a heat capacity of 4.2MJ per m3 and a vast volume are also warming by entire degrees, and it’s just staggering.

- syops 5y agoWhat does the energy of the Earth’s core have to do with climate? Outside of the effects of volcanoes I can’t think of anything.
- loopz 5y agoI just can't imagine why the bigger picture is never interesting. https://duckduckgo.com/?t=lm&q=earth+mantle+core+climate&ia=web https://duckduckgo.com/?t=lm&q=earth+mantle+core+climate&ia=...
- syops 5y agoFrom the first link it appears the effect is based on how the liquid flow of the core affects the orbit of the planet. The energy of the core does not play the same role on climate change as the energy that we’ve input into the system. I don’t think anyone is claiming the bigger picture isn’t interesting. Indeed, I did ask for clarification precisely because I was interested in learning something new.
- loopz 5y agoThe NASA study seems to be yet another vector to validate human-caused warming of climate. Validation is one thing, but also understanding exactly how and why we're moving away from an equilibrium vs core cycles, and what that may mean, may say something compelling. We're like fleas on the back of a giant elephant, and it might help to reorient to gain clarity. Mind you, I don't bring answers, only unasked questions and some wonder. The other thing is the enormous amount of geothermal energy, trapped beneath our feet. We may require energy, ie. to trap greenhouse gases and as replacement for fossile fuels. https://www.greenandgrowing.org/how-long-does-carbon-dioxide-stay-in-the-atmosphere/ https://www.greenandgrowing.org/how-long-does-carbon-dioxide...
