Removing subsidies on meat production and flying are the systemic variants of those individual choices. People would be vegan no-flyers in no time.

Or we’d return to the meat/travel consumption patterns of the early 20th century: trans-Atlantic trips being a once-in-a-lifetime thing or once-every-few-years for the well-off, and the Sunday roast/chicken being the highlight meal of the week.

Lol I’m probably a XIXth century time traveler regarding your scale. Not feeling unhappy, comme join me in the past guys!

The "radical" solutions are not just throwing more technology at the problems. That's how we got ourselves into this mess in the first place. The solution is to stop mindless consumption. We use the same material to wrap and bake food and drink unhealthy drinks as we do to build airplanes. We use plastic for use cases that take place over seconds and minutes and then throw it away. We drive everywhere because of poor…

I agree in principle. The reason we are not doing this is because it would destroy the economy and when that happens basically everything falls apart. We would still have enough food and essentials for everyone but loads of people would be without jobs and others would lose billions of wealth. A fully green economy might be possible in the far future but the transition seems like it is going to take a century or more…

We should send people like you together with phone sanitizers to search for a new planet.

You'll go first, the scientists will go in a second ship.

Thanks for posting the link so I could see the article. I did only skim it, and I'm surprised. I don't think it's an unreasonable criticism for 1997. But that's over a quarter of a century ago. He accepts CO2 is probably released by humans and apparently at a rate the sinks can't cope. He accepts that CO2 and other greenhouse gasses can lead to warming. But says that the data thus far had not borne out global warming…

Perhaps you're young. I'm 60 and have spent much of my life in geophysics applied to energy and minerals exploration, in the development of earth scale GIS mapping and computation tools, etc. In 1980 in computational dynamics classes looking at geophysics it was accepted that the volumes of CO2 being released were at a scale that would trap more energy and that steps need to be taken to reduce free CO2. This was scop…

I always think of Carl Sagan’s 1985 Senate hearing address[1] as a pivotal missed opportunity, too.

Enjoy a high standard of living now that you still can. This ship is going down. Might as well make the most of it instead of trying to carry buckets of water out of the hull, it's futile. Humanity has spoken, this is collectively what we want on average. Is it good? Is it fair? It just is.

> Enjoy living now that you still can.

Here, repaired it for you.

But our oil consumption essentially is our way of life. Changing it will have enormous effects on modern life. A lot of people are going to see a significant drop in their quality of life as a result. This is why it's so hard to change things in the first place, it's not about the companies, but about average people.

That seems disingenuous when the climate catastrophe is going to have far greater effects on modern life. Too many people are clinging to the dream of continuing to dig out and burn as much oil as possible when it's clear that that behaviour is not sustainable. Although personal responsibility is never a bad thing, we need to focus on the big companies that have been deliberately hiding climate science for decades -…

People don't dream about burning more oil, they dream about the quality of life that this process affords us. Things like uninterrupted power, (uninterrupted) running water, cleaner water, the internet, cheap food, enough food (fertilizers/Haber-Bosch process), accessible transportation, economies of scale etc. While few of these things require fossil fuels, fossil fuels are nevertheless the reason why these things are abundant and accessible.

People dream about living a good life. Our fossil fuel consumption has afforded this to many. That is why it's difficult to change. Companies don't make stuff for fun, they do it because there's consumer demand for it.

This study[0] and several other studies by UN, Oxford Uni etc disagree with you. The single best thing an individual can do is immensely reduce or completely avoid meat and dairy. Imagine millions and millions of people doing this, behavioural change will trigger system’s change. It’s something we can do today, just need to decide whether having a burger is more important or not. [0] https://www.nature.com/articles/s…

I everyone in the world adopted a vegan diet CO2 emissions would drop by 13%. Still eating pork, poultry, eggs and fish would reduce it by 8.6%: https://ourworldindata.org/carbon-opportunity-costs-food

From the article you've linked:

"In a hypothetical scenario in which everyone in the world went vegan by 2050, the regrowth of trees and wilderness could sequester around 547 billion tonnes of additional CO2. Each year we emit around 36 billion tonnes of CO2 from fossil fuels, so that’s equal to around 15 years of emissions at our current levels. They also estimate an additional 225 billion tonnes of CO2 could be stored in soils ..."

That's much more impactful than reducing emissions alone. It would store a load of carbon while preserving biodiversity (paramount for healthy ecosystems).

No one is really interested in doing the work to slow global warming. - Build nuclear power plants everywhere . Yes even in countries like Iran and North Korea - Don't subsidize fossil fuel use by any mechanism. Yes dropping the Russian fuel cap. - Make reducing emissions a priority that means it comes first in consideration. Yes ahead of Uighurs in China, Women in Iran and Afghanistan. You will not get everything yo…

Just stop having babies.

Why be passive? Design cars to kill their occupants turn them to compost. Even more green.

These personal decisions make little difference in the grand scheme of things.

"Be the change that you wish to see in the world." - Mahatma Gandhi

This quote emphasizes the idea that if individuals embody and practice positive values and actions, it can lead to a significant impact on the world around them. Similarly, if everyone were to act rightly, it would undoubtedly result in a different and improved world.

>You mean, like, switching to a vegan diet, using public transport and stop flying? Those seem radical enough for most people in the Northern Hemisphere. One of these things is not like the other. Vegan diets — and I support them in principle — do little or nothing to reduce carbon emissions. Vegan diets just don't deliver enough calories and essential nutrients without (industrial) supplementation, and veganism depe…

Such a load of bull. I'm sick of people ignoring the science. Educate yourself before writing anything next time. It's clear as day you're wrong. It's the most impactful thing you can as an individual do. We need to stop fossil fuels asap, stop animal ag (deforestation, pollution, biodiversity loss, etc.), reform agriculture (soils, biodiversity, poisons) and start reforesting/afforesting. There are tons of studies t…

> Such a load of bull. I'm sick of people ignoring the science. Educate yourself before writing anything next time

What are chances that everyone globally will just switch to vegan diet to save on CO2 before 2050 or whatever end date? My fair estimate is zero.

It's like wishing people aren't lazy or corrupt or that are more honest. To quote the poet "You don't get what you want".

At which point do you think humanity will start seriously thinking about radical solutions? Such as detonating thermonuclear weapons to throw enough dust above the troposphere to cool the planet down? I'm thinking we're still really far away. Migration from areas that become uninhabitable is still weak. And it doesn't look like any state that has substantial military/commercial/political power is interested in starti…

The German Greens are slowly inching towards nuclear, now the original 1980s membership are dying off and the Gazprom funding is running out: https://www.dw.com/en/german-greens-lay-out-nuclear-power-po...

The only function nuclear has is to keep the profits flowing for the same companies that have been running all coal plants. It's really just the same people who were opposing renewables because "too expensive" in order to continue running their profitable fossil fuel plants. Now that it's clear that that gravy train is running out they push nuclear, because they would be the only ones being able to deliver (in contrast to both wind and solar which don't require the same massive investments that can only be pulled of by a few small entities). The only problem they have is that the whole "renewables are too expensive" doesn't work anymore because they are actually cheaper, so instead they make up the baseload myth. Which already has a solution, overcapacity and investment into storage. In fact due to the long energy ROI for nuclear power plants, we would actually make things worse in the short term, because we need to use a lot of energy to build the plants. Solar and Wind are both on exponential curves (with no indication of slowing down), so why would we invest in nuclear? Use that money to invest in solar and wind (especially as long as we are still running fossil fuel plants), you get much higher CO2 reduction return on your investment.
