And I think the unstated conclusions are whether we should actually do "X" or not. I think the answer is usually Yes, we should do X (in this case, plant as many damn trees as we can), but I also think that's me arguing from an individual perspective and not a group psychology perspective.
Like, when people argue "but focusing on trees could distract us from addressing the entire problem", I used to just be dismissive of that, but I'm starting to feel like those objections should be taken more seriously - particularly having gone through this COVID debate where people focused so much on "flattening the curve" - which was necessary, not sufficient - that too many people signed on to gradual reopening just as the (high-amplitude) curve started flattening. If we had socialized a different benchmark, maybe it would have been more effective in the long run.
(But still, even if only in parentheses, plant trees.)
This whole argument is a great example of why we use prices and markets to decide on resource allocation instead of some other system. It's easy for people to cherry-pick evidence that their pet solution is the most efficient and to browbeat others into accepting that pet solution for non-economic reasons.
But when you have to attach a price to something, you have to essentially put up or shut up. Either your project is as efficient as you claim or you lose money. And if your project suffers from economies or dis-economies of scale? Prices can incorporate this information too. Prices keep us honest.
That's why a cap-and-trade system is the best approach for limiting and reducing carbon in the atmosphere. Put a price on the externality and the market will find a way to drive it down as far as it'll go.
I think that we should cast the widest net for possible solutions, but there does come a point where they need to be winnowed down to which solutions will have the greatest effect (without bad side effects) with the least time and material resources. It'll still have to be multiple solutions on multiple fronts, though. Planting trees should be an easy win where the ecology currently supports growing them without too much maintenance work, but some areas would require massive effort to revitalize. Nuance like that is important, and so I encourage everyone to take things a step further mentally each time you engage with these topics. Do some napkin math, read some studies, etc. The more people that do that, the more we can create working knowledge and solutions instead of just taking pot shots at various proposals.
Some of that work about possible solutions has been done by Paul Hawken. His Project Drawdown book is at least an organized and reasoned list of 100 possibilities. I attended a talk about one of them - marine permaculture arrays.
This is a body of working knowledge developed over the past thirteen years, with new inventions being developed and deployed for growing kelp in the open ocean. What's proven is the ability of wave, solar, wind powered pumps to upwell cold water hundred of meters beneath the ocean surface, and irrigate kelp, doubling the growth rate. This is important because 93% of global warming goes into the surface layers of the ocean, cutting of circulation of nutrients needed by life.
What's proven is that seaweeds and kelps can sequester more carbon per square meter per year than the tropical rainforest. The idea is put submerged, autonomous satellite-assisted kelp platforms in the open ocean at scale, to farm for food/feed/fertilizer/fish or just sink
the kelp into the depths to sequester the carbon for hundreds of years. (per UN research)
There is now a kelp coin, which might someday play a role in emerging carbon sequestration markets. At the moment, it is a fundraiser, crowd- funding style to help raise capital to get these to hectare scale.
https://www.climatefoundation.org/kelp-coin.html This kelp coin is new, just a couple of weeks out.
It might take a decade or more to get to a gigaton of carbon sequestration. But it is also about food security and ecosystem regeneration. If you like short videos for information, try https://www.climatefoundation.org/2040-make-a-change.html
No. There are nearly 8 billion people on this planet. Figure it out.
This is a complex problem. Almost all solutions are worth trying. Most of them are going to be required. There does not need to be a winnowing of solutions. We just need to fucking start rolling them out.
I'm so over the argument that something won't be good enough.
No fucking shit.
Nothing is going to be good enough, nothing is going to be potent enough to solve how monumentally we screwed the environment up.
I don't think it's a given we can reverse or even stop climate change. There are many positive feedback loops going on right now.
AFAIK neither the Paris accords or any climate management proposals entertain the idea of stopping climate change.
Edit: positive feedback loops are things like the melting ice caps. Less sunlight is reflected back to space by the white ice which means more is absorbed by the dark sea. This causes the earth to warm and more of the ice caps to melt....
In climate science there is something called the tipping point. This is when mechanisms like positive feedback will make drastic climate change inevitable (with current technology).
When the tipping point will happen is up for debate. IMO the idea that we have already passed the tipping point is also up for debate.
People frequently try to say the right things to convince the "stupid sheep" people but nobody bothers to think of how to convince themselves. Activists typically believe what they believe for bad reasons so they aren't able to make a good argument for why they're right.
How about estimate the future cost of climate change and the cost of various measures to prevent/reduce it. Do they result in a net gain or loss? There's no point doing something will help less than it hurts.
It's hard to predict future costs but we should at least try instead of (incorrectly) pretending it's the end of the world and no expense is too great to stop it. People probably have a sense that some measures (like reforestation) might not be worth the cost but others consider any cost is worth paying if it does anything.
Any investment can be argued to be not worth it before the return is received. If you constrain the timeframe to exclude the timeframe of the expected return, then of course it won't be worth it. Point taken if you're talking about a sufficiently long timeframe, though.
Second, there's the behavior of the thing you're trying to fix. If you're accelerating towards a wall, you don't analyze the cost of switching to your current velocity. You're still going to get smashed apart by the wall. With Covid, people wondered if a lockdown is worth the economic cost compared to not locking down, without stopping to consider if no-lockdown's economic cost exceeds the cost of the lockdown, which is the bleedingly obvious reality. Comparing the cost of mitigating climate change over not mitigating climate change sometimes ignores we aren't in a static reality - the status quo is that we are accelerating in a direction that leads to higher and higher costs.
Finally, the return on an investment can change over time. For many people, planting one tree is obviously worth the cost of planting one tree. I've got space in my backyard, and I have seeds. It's a few square feet and it sequesters about a ton of CO2 over 40 years. I mean, that's a hell of a return on an investment, compared to not planting the tree. Now, that return will go down over time, as it becomes harder and more expensive for society to plant trees, several billion trees from now. But right now it's easy money. A US Citizen can currently offset their own carbon footprint by paying tree-planting services somewhere between $120 and $200 per year. That's cheap. It'll get more expensive over time until the point it's not "worth it" by some argument, and that can also mean that "the effort of offsetting the worlds carbon footprint through world reforestation isn't worth it", but that doesn't mean it's not worth it at first.
Ok I read the entire thread and I don't know where to plug my comment so let me do it here.
I recently drove through a road after a couple of years. On one side is Safeway and other shops - standard California shopping area - bigger than a strip mall smaller than a mall - not sure what to call it, and housing on the other side of the road.
Maybe it is bad memory but maybe it is real since I sort of exclaimed when passing through the area. The area used to be a concrete jungle but now they added so many trees that if you were not looking you may not realize you are passing a shopping area (of course I exaggerate but just a little). Not sure if they added 10 trees, 100 or maybe 200-300 (smallish ones not full size ones). I wonder if those things help and to what extent?
It's a different lense we need, this would be the argument: we should do x,x if we do it won't have enough effects by itself, it's better than nothing to have that desired effect, it's a step in the right direction to achieve the desired results, what we need to have is other people to also have the desired effect to do the same thing independently. The question is what is the effect and how much of a piece of the whole would it mitigate. Can the people who do decide to make a change in that one goal can they compare notes to improve on that outcome.
Tldr: do what you can based on where you are at your life and hope improves in the right direction, this applies to all things.
- We should do "X"
- But doing "X" won't solve "Y"
- But "X" will help
- But "X" won't solve
- But "X" is necessary
- But "X" isn't sufficient
And I think the unstated conclusions are whether we should actually do "X" or not. I think the answer is usually Yes, we should do X (in this case, plant as many damn trees as we can), but I also think that's me arguing from an individual perspective and not a group psychology perspective.
