Energy is what matters, not carbon.
You're ignoring of well-established science. CO2 remains resident in the atmosphere for 1,000s of years after it's emitted by combustion. During those millenia, vastly more heat is trapped via the greenhouse effect than was tapped for useful work when that carbon was burned. Perhaps the least energy efficient mechanism ever devised.That's just silly. Energy is what matters, not carbon.

Note that it's actually even worse than that:
This is why atmospheric CO₂ is so dangerous even at low concentrations: methane might be a more potent greenhouse gas but its half-life is only 12 years (i.e. once we get fracking related methane emissions under control there's only about a decade of overhang) - but about 30% of the CO₂ has a half-life of hundreds of thousands of years, the other 70% gets absorbed via ocean acidification (a catastrophic mechanism) with a half life of over ~100 years.
- CO₂'s normal half-life in the atmosphere is 20-200 years according to the IPCC, but that's only due to the primary CO₂ absorption mechanism of it being dissolved by ocean water.
- But ocean water is a limited resource in itself: there's a hard ceiling to ocean acidification (which tipping point we might already be getting close to) which will have catastrophic consequences to marine life and much of the rest of the planet.
- The actual half life of the other mechanisms is measured in hundreds of thousands of years: chemical weathering and rock formation.
Indeed, the IPCC report cites Shine et al. (2005c) with a revised AGWP for CO2: "The assumed lifetime of 1,000 years is a lower limit."This is why atmospheric CO₂ is so dangerous even at low concentrations <snip> but about 30% of the CO₂ has a half-life of hundreds of thousands of years, the other 70% gets absorbed via ocean acidification (a catastrophic mechanism) with a half life of over ~100 years.
Another reason to hasten the end of the oil age. The environmental impact of oil leaking from neglected wells in Venezuela is frightening and looks like the apocalypse...Here we go again... The end of the oil age can't come soon enough...
This could dampen the markets today, although reading the article it does't sound particularly serious.
Explosion sets ablaze Iranian oil tanker off the coast of Saudi Arabia, Iranian state media says
An explosion damaged an Iranian oil tanker traveling through the Red Sea near Saudi Arabia on Friday, Iranian media reported. There was no immediate word from Saudi Arabia on the reported blast.
State television said the explosion damaged two storerooms aboard the unnamed oil tanker and caused an oil leak into the Red Sea. It did not elaborate.
Point to the carbon in nuclear power.Why do you say that? Energy that pollutes, from fossil fuels, drives up the Keeling Curve, eating away at our remaining carbon budget. Not sustainable.
Energy that is emissions free - from solar panels made using solar energy, has no effect on the Keeling Curve. It’s greenhouse neutral. Sustainable.
It’s the carbon combustion that has to be avoided.
