let me guess we only have 10 more years, again?

Re: Global warming has accelerated significantly
#462FWIW my personal assessment is that this acceleration is both real and largely out of our control. Models in the past did not attempt to account for non-anthropogenic carbon emissions, but as we experience further warming, most especially in the Arctic, feedback loops and tipping points mean that this (carbon emissions caused by “natural” processes) are becoming more evident. This is especially sensitive because a la…
> I’m of the opinion that direct air capture is the primary escape hatch we have for not hitting 3 or even 4C warming in the next 100-200 years
Why is it always never 'burn less fossil fuels'.
Anything but the oil company bottom line huh?
Re: Global warming has accelerated significantly
#463Nothing will change until developed rich countries are starting to hurt. And I don't think it's going to hurt enough in 10 or 20 years. The pain will come slowly, people won't see it. It's like going back to the middle age so slowly, that the population don't realize or feel it. And honestly, wars and trump are making climate concerns so difficult to think about.

They already are. China does whatever it wants en mass meanwhile.

What about solar shades? Seems like a relatively quick and easy way to regulate solar input. It's nice too because you can quickly remove it if necessary.
How long would a single cargo-load of shades have to be operational just to offset the amount of CO2 emitted by its launch?

#465El Niño, volcanism, and solar variation. it's not about us guys, relax.
Any excuse to pretend we aren't contributing.

Excellent comment. I would only add two points. I think it's important to mention the effects we're seeing today are caused by the emissions from decades ago. Second, not sure if the paper in the OP touches this but we've reduced aerosols in the atmosphere. These previously were masking the effects of climate change by cooling the temperature.
The paper states it adjusts for "ENSO, volcanic eruptions, and solar variations" and not (afaict) the changes in shipping bunker fuel that reduced atmospheric SO2 (if that is what you mean by "reduced aerosols"). Below is a summary of the topic for those who are unaware. I withhold any opinion of validity of mechanism or effect.
Sulphur particles contained in ships' exhaust fumes had been counteracting
some of the warming coming from greenhouse gases. Lowering the sulfur content
of marine fuel weakened this masking effect, effectively giving a boost to
warming.Re: Global warming has accelerated significantly

You must be American.

Hilarious take. China and India have historically emitted much less carbon than many western countries, per capita they emit less Co2, and a large part of emission is to produce for western countries, which have effectively outsourced their emissions to other (poorer) countries. At the same time, the US is the main force fighting against carbon neutrality, renewable energy and pretty much anything reasonable. By dire…
China has long surpassed most countries in per-capita emissions and is still on an upward trajectory. India is on an upward trajectory but still below the world average. The US and Canada are higher than China but on a downward trajectory. The EU is on a downward trajectory and below China. https://ourworldindata.org/grapher/co-emissions-per-capita
You quickly start seeing people's root biases about when you bringing info like this up, "well but historically ...", "you know, the colonialism", "per capita ...", etc. I wish we could deal with the here and now and deal with this scientifically.

China is some years behind our industrial development then undevelopment, and is building an entire USA of solar panels every year or whatever - can we expect them to quickly reduce emissions soon?
I thought the world and civilization would collapse because of carbon emissions. It's either serious or it's not. If it's serious then it doesn't really matter right? It's like you're on a boat that sprung a leak and everyone grabs a bucket. But a few people choose to not help because it's not fair for whatever reason.
What?

> Nothing will change until developed rich countries are starting to hurt. Ironic OECD countries actually REDUCED their emissions based on a peak in 2007 and continue to do so. Not reduced as a percentage of GDP or adjusted for population growth, but reduced in absolute levels. It's all China, but I guess it's cool to blame things on developed countries. There are literally 100k deaths in Europe that can be prevented…

Any idea what percentage of this reduction is due to offshoring manufacturing?
