Honest question. If during the warmest periods ice melts all over the planet, wouldn't ice cores lack carbon measurements for those periods? I'd love an answer from someone with some expertise.
Sure, but that hasn't happened for at least 2.7 million years. https://www.sciencemag.org/news/2017/08/record-shattering-27...
That article says that the oldest ice in the core was 2.7 million years old. It actually mentions gaps in the record and ability to date ice only with a 100k year margin of error. This does not imply that we have a continuous record of carbon levels for the past 2.7M years.
china measured emission are about half of usa measured emission. china non measured emissions are another story. soot is yet another story, because not all co2 is created equally efficiently. https://www.reuters.com/article/us-china-climatechange-insig... oh, and there's all the other shit china does of course https://nationalpost.com/news/world/scientists-discover-chin... but somehow people dodge the issue every tim…
If that is true, then the situation seems intractable. The Chinese government won't want to pay for anything beyond it's official figures, but the rest of the world has no interest in those bogus figures being used.
I think it’s possible to get a decent overall estimate of emissions in a given area by measuring local variations in CO2 levels.
This doesn't even touch Chinese coal emissions. The latter are easily visible from space, and unlike ours are recently deployed and continue being built.
I believe in China and India they would point out that the West allowed itself to emit pollutants unchecked during its period of rapid economic growth, and it would be ridiculous to ask the East not to do the same. It's more complicated than just passing the buck.
Can we stop with this "growing phase" mythology of high carbon emissions? The US didn't "grow out of it" we out-sourced it to China and India. China and India can't "grow out of it" unless they find someone else that can take it over for them (and I don't think there's enough production capacity in the remaining parts of the world to do this). This article[1] does a pretty good job showing the complexity of this. The…
Depends on what you mean I think. Yes growing out of pollutants is a myth. But it's not wrong to say that India and China are in a period of rapid economic growth where they catch up to their industrialized peers. You might argue that the West never went through such a phase at all, because it was ahead of the rest of the world for all of modern history, but I think that's splitting hairs. In any case, my point was trying to be descriptive about what arguments I think you'd realistically hear, rather than to stake a position either way on the arguments.
