I fear the only possible way through this by deploying solar geoengineering-- soon-- in order to buy us enough time to scale up carbon capture. In addition to transitioning our energy infrastructure and transportation. It can be done.
Letting these conditions continue will almost certainly result in destabilization that make an organized response even less tenable.
That's harsh but not as bad as some places right now. Ironically, the only thing it will lead to is people turning up the AC closing the feedback loop.
Exactly. It's 1.5 degrees Celsius to heat 5x10^15 tonnes of atmosphere. That's a mind-boggling amount of energy and it has to go somewhere, all that power is available to disrupt our 'normal' weather systems.
The laypersons interpretation of 1.5 degrees change is 'so what, it will be a little bit warmer'. The difference between those two views is very hard to reconcile, simply because of the scale.
Solar geoengineering is unproven technology; is there even any estimate on how much it will cost and how long it may take?
Lots of things can be done. Most of them won't. People prefer denial - not everyone, but enough to sabotage progress. The pandemic has made this abundantly clear.
It's generally agreed to be highly cost effective. Via Wikipedia:
> The annual cost of delivering 5 million tons of an albedo enhancing aerosol (sufficient to offset the expected warming over the next century) to an altitude of 20 to 30 km is estimated at US$2 billion to 8 billion. In comparison, the annual cost estimates for climate damage or emission mitigation range from US$200 billion to 2 trillion.
> delivering 5 million tons of an albedo enhancing aerosol (sufficient to offset the expected warming over the next century) to an altitude of 20 to 30 km
... How much CO2 is that going to emit? Is that achieved by aircraft or rockets?
How many MJ/tonne does that take? How many sites do you need? How many more nuclear plants does it take running continuously to manufacture and launch all this?
Who pays for this?
How do you persuade them?
How do you protect it from getting cut by the denialism faction as soon as they get elected?
If you deliver it by aircraft, that's about 40000 flights per year (assuming you use Boeing 747-400 or comparable). That sounds like a lot, but right now there are 10000 aircraft in the air, adding 40k flights a year isn't going to throw the numbers off.
The bigger issue is that aerosol delays the "warming" issue, but doesn't stop ocean acidification (in addition to the issue of what happens if we ever stop for whatever reason)
The cost is not the issue most people have a problem with; it's the general idea of geoengineering without (much) regard for unknown side effects. Also, geoengineering without fixing the root cause is backwards and risky. Reducing emissions is the best thing we can do and this process is actively sabotaged by the right-wing politicians and media. If reducing emissions is such a hard sell, geoengineering will be even more difficult to do.
Increase taxes on the wealthy, use the money to improve inequality and pass legislation that heavily taxes or bans pollutants at the corporate level. Guarantee long jail time for leaders caught cheating the system.
None of the climate change problems that exist are technologically hard to solve. We have solved much harder IMO. The problems are all political and denial-based. Removing the denial would go much further than any particular technological solution will.
You'll need to do better than just stopping emitting, you will have to undo some of the damage to have a chance to get back to equilibrium, all else is just a - relatively short - stay of execution.
The last 200 years has seen humanity reverse a climate trend that held for many millions of years and yet there are still people that believe - strongly - that this is all just coincidence.
I'm re-reading my comment, and trying to see how could you construe I'm advocating for only stopping.
To make it clear, I'm simply stating that if you only work on something to "reverse" or "clean" you will not be successful UNTIL WE STOP EMITTING. (emphasis, not yelling).
So until we stop emitting, it's spinning wheels with no forward progress.
You may actually have to emit more for a short time in order to be able to emit less in times further out, a bit like a mortgage downpayment, it hurts, but not as much as paying the interest further on.
Solutions will come with a price tag, either in terms of funds, or quite possibly in terms of short term CO2 emissions on a scale even larger than the one that we have currently. But they had better be off-set by much larger savings further down the line. So 'stopping emitting' may not be a valid option, except for some things that are luxuries. Meanwhile, people will have to eat, there will have to be some level of transportation, there will be all manner of consumption all of which will continue emissions. To offset that and fix the damage is going to be the literal challenge of our lives. I hope you like seaweed, and I'm not sure how we'd go about farming that in sufficient quantity and with low enough emissions that we won't end up with massive famine and wars in the next 80 years or so.
Bluntly put: there are too many of us to sustainably live on this planet at our current level of technology, and at the same time there may be too few of us to mitigate the damage already done. Stopping emitting = mass die offs, wars, famine and so on. Unless you're resigned to that I would research for a while to see if there are better options that will avoid those, because even though they are probably quite effective they lack in humanity and empathy.
I'm not overly optimistic that such solutions are still on the table, but it can't hurt to look, though I'm skeptical about us being able to muster the necessary levels of cooperation, to start thinking as a species instead of a bunch of unrelated fiefdoms that can act independently of each other when it comes to major items of policy that affect everybody everywhere.
I'm saying at this point we probably need both. Solar radiation management and reduced emission (and hopefully negative emission AKA carbon capture in the future, but the tech isn't there yet).
Even if we stopped emitting all CO2 tomorrow, we're still likely to see another half degree of warming. Maybe more. I can't imagine what that would do my home in the western US. Or Greece, or Turkey, or any of the places around the world already experiencing catastrophic flooding.
There's no scenario where we reach net zero emissions in a decade. I'm not saying we should start geoengineering without further study. Only that at the present moment, from my perspective, it seems like the bigger risk is not to geoengineer.
Preparing for and dealing with something like COVID would have been highly cost effective as well. And yet, here we are. Climate change is a lot harder on the scale of problems to deal with.
In an ideal world, everyone in every country would have coordinated and stayed inside for a month while the virus died out. Now, just because the ideal measure wasn't taken, folks pretend we're experiencing the worst possible outcome from COVID. This has been far from the worst possible outcome. Let's stop acting like our response to the pandemic was a complete failure when it simply wasn't.
COVID isn't over by a long shot, we're smack in the middle of it - if we're lucky and this is the half way point -, if we're unlucky this is just the start.
Of course we should do what we can. But if this is far from the worst possible outcome, imagine the relative complexity of scale between a virus jumping species and trying to undo 200 odd years of runaway emissions and the effect on our climate in the next couple of decades and gain some appreciation for the change in scale and intensity of cooperation required to achieve a meaningful difference.
Optimism is a great thing to have, but let's not delude ourselves: humanity is in for a very rough ride, and there is absolutely no indication of how - or even if - we will weather this.
HN is supposedly one of the smarter fora on the net, and yet, every day we are overrun by conspiracy nuts, people have been shouting down the ongoing pandemic since day one - and merrily continue to do so day by day. Forgive me if I'm not all that optimistic about how we are going to deal with something far harder.
I'm not looking at the number of comments from conspiracy nuts as a measure of success or failure, I'm looking at the confirmed case counts and death counts. Considering how pernicious this virus is, our prevention efforts have not been a complete failure. The death count could easily be an order of magnitude higher today. That's not blind optimism for the future, that's the reality of the present.
You need to add one giant qualifier there: 'in the developed world'.
So far what we've managed to achieve is to stave of the worst at the expense of ruining our economy and now having to deal with a whole pile of new and nastier variations.
You can't really say anything about the outcome of a fire until the fire is under control, right now we may have the illusion of control but I don't believe that we are there just yet.
That doesn't matter. I was replying to a comment about our response to the pandemic. That comment indicated our response was a failure based on what we know today, and I disagreed that it was a failure based on what we know today.
It is a failure compared to what we already knew back then.
If people had just been smart enough to listen to Mike Ryan instead of bashing the WHO we'd be in much better shape today. All this slow-walking cost us dearly. That it could have been worse is true. But it also could have been much better.
I watched that this afternoon in a mix of sadness, disbelief (though I know better) and worry about the fate of the people who did not manage to get on that ferry in time, either because they were stubborn or simply because they weren't mobile enough.
I am not looking forward to the future “resource” wars as we begin to see significant decreases in habitable land; water scarcity; food shortages; and decreases in oxygen quality (clean air).
This is already happening in poorer countries with less of a safety net. Somalia comes to mind. Expect the refugee crisis to continue to escalate.
Edit: In the meantime, please act. I'm calling on everyone in the tech community to exercise your agency. Get politically active. Invent new solutions. Change jobs if you need to. This is the most important problem to be working on right now, and will continue to be until we achieve gigaton scale carbon capture.
Denver worst among international cities for air pollution today, smoke plus ozone. We've had 34 straight days of warnings, with recommendation to only drive ZEVs, not go outside if you're in a vulnerable category which happens to include young children. Local politicians have rejected all mandatory actions, and only support voluntary solutions. As a result of EPA policy, we'll get a new mix of gasoline... next year.
This isn't heroism. This is complete and utter stupidity. Whoever wrote this article should be fired on the spot.
The advice is there for a reason. People die doing this all the time. I know someone (a child at the time) whose parents went back to try protect their house. That child was raised without parents.
People are generally not equipped to see their life's work annihilated in a couple of minutes and will quite literally die to protect it. That's human nature and you should not be too harsh on them.
Good luck with that. You can't tell people a life long that their possessions and their future are entwined and then yank that away from them and expect them not to - briefly - be in a state of confusion. It's pretty easy to be all rational from a couple of thousand miles away but these scenes play out over and over again in the face of imminent natural disaster.
Berating those people is not going to solve it, and I suspect as these stories become more common people will give up their possessions more easily once realization sets in that their attempts are futile and only endanger them. But we are not there yet, and in some ways that is fortunate. The time when that sort of feeling becomes more commonplace will be harsh.
Regardless of any heroic action on climate, the trend will probably continue. I think it's time to stop hoping for "a solution to climate change" and start considering mitigations.
The problems of excess heat, from heatstroke to infernos, can be partially addressed by water management. We know we are already approaching shortages of fresh water. So one big mitigation we could do is a new strategy to conserve and distribute water where it's most needed due to climate change.
I imagine massive engineering projects to identify sources of fresh water and start distributing them over populated areas. The Romans built their aqueducts over hundreds of miles to bring water into their cities. Well, imagine a nation-wide distribution of water. Unless we want to completely abandon formerly-habitable swaths of the planet, we may need to start "plumbing the world" to share what little water remains.
Imagine root-like networks of fresh water that can be activated to tamp down on the spread of fires into cities, or accessed for cool drinking water by anyone who needs it on a hot day. More acquifers to collect and process rainwater. Tighter regulations and enforcement around the dumping of harmful material into waterways. Additional regulations or taxes on excess commercial uses of water. Desalination plants to contribute more water (regardless of cost, it will probably be necessary due to increasing lack of fresh water). Development of new technology to reduce the need for water. And finally, regulations to eliminate wasteful use of water in general (we can't keep watering lawns forever).
There's plenty of water in the world, but most of it is salt water from the oceans, so if we can desalinate it that will go a long way towards solving the water crisis -- particularly in areas near the shore.
It would be interesting to hear what a per-capita price of a gallon of desalinated water would cost, especially when the cost is brought down by having lots of desalination plants all around the world.
Right now desalination is too expensive. I think that we will eventually reach the point where it's necessary regardless of the cost. But I also think we shouldn't bet on them entirely; we should have a much larger water management plan where desalination merely fills gaps rather than provides the bulk of our water. Even if you got desalination cheap enough for local production, transportation would make it even less affordable, so we really need to max out the efficiency of existing watersheds, water tables, and snow melts. And we could further increase efficiency by redirecting water from other parts of the country, the way we (sort of?) do with energy.
We need to return to vernacular architecture, passive solar design, smaller homes in walkable neighborhoods. Our overhead for just existing in the US is insanely high and it's hard to opt out. Small towns and unincorporated communities need to decide to make it possible for some part of their population to opt out.
We invest too much in worshipping the big city, among other things.
But this kind of stuff is exactly what requires top-down changes. There are specific governmental regulations and economic incentives that encourage the current way of living. You'll need different laws and a different economic environment to make a change here.
The appearance of firefighters minutes later and his own heroic efforts saved the entire neighbourhood from being reduced to cinders.
Like many, Rizos believes the climate emergency will only get worse. “We’re ecologists, we love nature in my family and we want to protect the environment, not install air conditioners that will destroy it. But with temperatures of 45C, that’s going to be hard. We have to adapt. For sure, I’ll be replacing pine trees with other trees that don’t burn so easily.”
We need more people thinking like this. I don't know how we get people to take things seriously and act.
It needs to be local. It needs to be wise more than smart. We need more small solutions to push back against the effects of our top-heavy world where money and power and the like often sweep in with no respect for local traditions just because they can.
I don't know how we get there from here. I know it doesn't help to presume it is a foregone conclusion that we can't make a meaningful difference at this point and we are simply doomed.
I hear you, but it's not possible to mitigate our way out of this. It's simply happening too fast. Of all of the carbon that's been released into the atmosphere since the industrial revolution, half of it has come in the last 30 years.
Over the course of a millennium, sure, maybe even a couple of centuries. But we're looking at a single generation to get this done. And that's without burning a huge amount of oil to make it happen.
“While they were saying among themselves it cannot be done, it was done.” -- Helen Keller
My incomplete BS is in Environmental Studies.
I have trouble believing we are doomed to failure and there is no point in trying. If you don't bother to try, that sounds like self-fulfilling prophecy to me, not proof that we couldn't have accomplished something if we had tried.
For sure! For the record, I do think there's a path to success here (see my prior comments), but it's fairly top-down in its approach. Still, everyone has a role to play in demanding that their governments take immediate action.
Some mitigation is absolutely necessary. But mitigation alone can't prepare us for 3°C. Billions of people will die.
That's exactly the problem. Every potential solution starts with either one of the following assumptions (1) some technology that we do not have access to (either at the required scale or even at all), (2) unlimited funding, (3) unlimited energy that does not somehow make the problem worse, (4) unlimited time.
We have none of these, I can think of a possible solution but you're not going to like it.
We need a CO2 tax to account for this devastation. Folks that want to save money today by not introducing a CO2 tax ought to consider what precious little that saved money will buy if crop land turns to desert and the world is aflame. Folks can’t spend money if they end up in an early grave.
So put the CO2 tax money toward EV credits, solar, wind, batteries, carbon capture and power-to-gas tech, etc...
This isn’t a consequence free world we live in. If we forsake the earth, I’m afraid we will be forsaken.
>So put the CO2 tax money toward EV credits, solar, wind, batteries, carbon capture and power-to-gas tech, etc...
It's a pretty well known meme that "the government shouldn't pick winners and losers" (specific technologies).
Sure, maybe it's not always true, maybe you disagree, but couldn't you at least address how/why?
Why can't we have a CO2 tax and not choose what to subsidize, because we (some would say) will surely get it wrong and if anything matters, that matters.
I think a tax should be added to discourage the behavior and the money put toward cleanup (CO2 reduction) in order to remove the risk of further damages. I don’t think much of the clean tech spending is speculative at this point.
I’m not as worried about us getting it wrong because I think we are already well wide of the mark and have plenty of opportunities for improvement. We’ve continued down the cheap and easy route of fossil fuel extraction and haven’t been looking to make the seemingly more painful choices. It’s not too hard to imagine how we could ween off a good quantity of fossil fuels.
One could justify the spent tax money with high expected CO2 reduction choices. This would, in my view, gets us to a better outcome faster.
Here’s my opinion on a some of the consumer side products that can help today. The tax money could go towards credits for purchase of products like 30-50% off EV, solar, battery, insulation purchases. Government side decisions like replacing coal plants are also high expected CO2 removal projects.
We might ramp up more speculative tech based on the needs (e.g. carbon capture and power to gas).
Hope that helps explain where I’m coming from. With any luck we have more margin for error, though I’m not wanting to count on it.
I listened to a podcast once about somebody wanting to build a mr burns style sun blocker, except in space and extremely far away from us. The idea was to reduce the amount of sun that hits the earth by a couple of percentage points. It wouldn’t even be visible in the sky they said
