I was on a road trip this weekend, and we had to clean the windshield 5 times. So it looks like the bugs are making a comeback thanks to restrictions on Monsanto products.
Indoor farming isn't scalable. At least not with the models that are being done now. They work for niche crops, but not staple carb sources like potatoes and grains. They can be profitable, but aren't a catch all solution.
The ocean cleaning projects also don't scale. We should be focused on keeping the trash from getting into it first by switching to recyclable and biodegradable packaging and forcing the fishing industry to switch back to hemp nets.
I don't think that scalable and profitable are goals of indoor farming. It's done for self sustainability.
kind of an ironic choice of template for the message
This is what I’m banking on, things get bad but that would motivate us more and it would become easier and easier to address.
Having said that, I think degrowth is the correct way; the above is risky but better than doom and gloom.
Building out more and more renewables doesn't mean anything if emissions aren't falling - and they aren't. Since 2021, nearly 4 full years, the world has closed less than 1% of active coal power plants.
The buildout of renewables has arrived hand-in-hand with an increase in total energy usage. The energy mix has improved greatly in favor of renewables, tons of CO2 per KWh is way down, unfortunately we just use more KWh so total emissions are still rising.
Everything in the meme is a leading indicator for positive change, which is wonderful, but the actual change needs to materialize on a rather short timetable. Stories about happy first derivatives don't count for much.
Didn't Britian just close down it's last coal plant? Also Colorado is switching away as well. I thought natural gas was replacing coal?
Since 2021, nearly 4 full years, the world has closed less than 1% of active coal power plants.
Closing will come later, when alternatives are widely available. What renewable energy does currently - at least here - is forcing those plants temporarily out of the market, especially during summer months and windy weather. The plants will exist and stay ready in case of need for well over a decade, maybe even two - but they will start up ever more rarely.
Technically, the deal is: we don't have seasonal energy storage. Short term storage is being built - enough to stabilize the grid for a cold windless hour, then a day, then a week... that's about as far as one can go with batteries and pumped hydro.
To really get the goods one has to add seasonal storage or on-demand nuclear generation. The bad news is that technologies for seasonal storage aren't fully mature yet, while nuclear is expensive and slow to build. There's electrolysis and methanation, there's iron reduction, there are flow batteries of various sorts, there's seasonal thermal storage already (a quarter step in the right direction)...
...but getting the mixture right takes time. Instead of looking at the number of closed plants, one should look at the sum of emissions. To remain hopeful, the sum should stop growing very soon.

That was in the link I posted. Emissions are Currently at record highs.
Slowing growth isn't enough; we need significant, sustained, reductions in the very near future, and negative emissions and sequestering carbon in the medium term.
None of that is happening at a scale that would inspire optimism.
One technology that's being developed that can help is high-voltage superconducting DC power, which can send power thousands of miles. So if it's a sunless, windless day in the Northeast they can send power from the Midwest to stabilize the grid.
Also, I'm very bullish on Iron-Air batteries for long-term grid-level storage.
From your link it, for me, it seems like emissions are platooning, similar to a technological S curve. Even if China and India are growing exponentially, reduction in other countries are enough to slow down the process significantly (specially if you zoom in in the last 10 years).
It’s very hard to predict change, but I suspect the deprecation of solutions that emit lots of emissions is about to skyrocket.
We might already have reached peak carbon emissions. There's also the thing where renewables are so much cheaper that it's in most countries best self interest to build renewables.
The thing the world is doing now is more energy but the cheapest one is electricity so more electricity. The duck curve is an energy storage opportunity that's being taken advantage of more and more. Things are heading in the right direction but it's not fast enough.
The next emissions on the chopping block are household heating and cement and low-med industrial heat with more advanced heat pumps or heat pumps set up in series.
I've decided to become cautiously optimistic recently the more I learn about how science is advancing the renewables despite governments sometimes being in the way.
Why perchance has the interest in a self-sustaining life skyrocketed you think? Could it be because people can barely afford food anymore?
Not just that, it’s a combination of factors. Sustainable thinking, independence, a connection to the world and self and much more.
I worry that climate defeatism has become a religion, and it will be difficult to separate it from policy discussion going forward.
Things just shifted instantly from "nothing needs to be done" to "nothing can be done."
The Climate Denier's prayer:
The climate isn't changing,
and even if it was,
It's not humans that are causing it,
and even if we are,
It's better for the economy if we ignore it,
and even if that's not true,
There's nothing we can do about it anyways.
It certainly hasn't defeated MY adoption expectations, and don't even talk to me about stock share prices for anything involving solar.
By the power invested in me by, well, nobody whatsoever, can I just take a minute to say, let's all cool down a little in the comments!
There's a lot of arguing against:
I don't see anyone making those arguments here though! Just lots of people concerned about climate change with different skews of how positive/negative we should feel.
Personally, I swing between powerful optimism and waking in terror at 3:00am for the future we're hurtling towards. I'm sure other people are the same, so let's just be friendly to the fact that other people are in different vibes to us.
There are some people working together very well right now to dismantle the climate, so let's all remember that when we're talking with each other.
Peace and love!
Is it defeatist to face the facts that we have released more carbon in 2023 than any other year? Is it defeatist to realize not only are we polluting non-stop, we are also destroying the oceans, we are destroying ecosystems and we are destroying ourselves at a rate that we can't control? That a majority of people are content living their lives this way if it means they don't have to make the hard choice of having and using less? We're already well past 1°C and are not going to slowdown it seems until its too late.
Interest in solar panels has skyrocketed, and yet at least 50% of the world population won't stop driving ICE cars to work every day any time soon. While the ocean surface temperatures are on an exponential trajectory.
A climate catastrophy with mass deaths is inevitable. I'd be preparing instead of sugar-coating.
And after a few billion humans die, we can deploy solar panels and start living sustainably.
Yes, this exactly! The polls about sustainable living mean nothing when the ice caps melt, when the wildlife has been reduced to basically nothing and when we are all struggling to breathe with no trees and no plankton to produce oxygen.
CO2 emissions of the world excluding China have declined. Chinas emissions did fall in Q2 of this year.
Seriously China has economic trouble, which slows down energy demand growth. The US has run the massive inflation reduction act, which seems to be working somewhat well and Europe was hit hard by the energy crisis reducing emissions in the EU through lower consumption and faster green roll out and Russia as its fossil fuel exports fall. On top of that green technologies like solar panels, wind trubines, electric vehicles, heat pumps and so forth become cheaper all the time. It is certainly possible that we can achieve peak emissions soon.
It's like praising all the cabin cars getting repainted with eco-friendly paint while the train has already gone off the cliff and is plunging toward the ground.
I approve of the overall message but indoor farming is kind of insane in the present day. It uses incredible amounts of energy and our scarce building materials to do something we can do much more easily outside.
Long term it might be important but I don’t think it makes sense until we solve the current energy crisis.
Using solar panels to power artificial lighting so you can vertically stack farms directly inside cities doesn't make any sense from a sustainability perspective.
But greenhouses in the suburbs that are tied into the city's thermal grid and seasonal thermal energy store is the future of agriculture IMO.
By enclosing fields in greenhouses you decrease the land, water, pesticide, and fertilizer requirements, while also eliminating fertilizer runoff and the possibility of soil depletion from tilling. By tying a greenhouse into a thermal grid the greenhouse can act as a solar thermal collector in the summer while maybe even condensing the water that evaporates through the plants for reuse. Then you can use that same heat to heat homes during the winter or extend the growing season in the greenhouse even further.

https://www.washingtonpost.com/business/interactive/2022/netherlands-agriculture-technology/ (Yes I know they use artificial lighting in a lot of these, and yes I know a lot of the value of their agricultural exports comes from flowers, but the point is it's another example of large scale greenhouse use. Also they do still produce quite a bit of food in a small area, in addition to the flowers.)
So what is this indoor farming for cities?
I remember those boxes to grow salad in, vertically stacked, interesting concept because no need for toxic stuff and almost no water, and it's right there so no need for shipping.
You still need fertilizer and electricity that is less efficient than sunlight to grow indoors.
But somebody once gave terrible math about being able to feed a city from a vertical skyscraper farm and it's been latched onto very hard as a futurism solution.
Been growing plants for 30-years, using zero sunlight to full sunlight. The difference in energy use, manpower, all that, is stunning.
Food is food because it contains loads of energy. We eat corn not oak leaves. That energy has to be put into the plant, at a loss, to get energy out. TANSTAAFL, literally.
This seems like a weird argument. One has to come before the other. You won't see a noticable reduction CO2 emissions until renewables are primary sources for probably decades. Sure that's not great but it's where we're at.
thank you.
