I've heard that with the droughts and the fires and logging and land development the amazon basin is slowly turning from a net carbon absorber to a net emitter as there isn't enough new growth to counter all of the previously mentioned factors. Sad!

:marseysad: It's the same here. Luzon and all the major islands used to have lush rainforests and mangroves lining the shores, which provided natural protection against hurricanes in addition to having really cool indigenous wildlife like the Philippines crocodile. What little is left is protected but the magnitude of the loss really hits you when you go out island hopping and see what things would've looked like before getting paved over.

One of the main parishes we attend has a standing weekly prayer admonishing humanity for the poor stewardship we demonstrate and beseeching God to protect us from natural calamities. The reception western !Catholics gave to the recent encylical on climate change was shameful.

A primary miracle attributed to the devotion to the Sto. Nino de Cebu (original statue was gifted by Magellan himself) was protecting the Cebuanos from a category 5 hurricane in the 16th century that wreaked havoc in Visayas. Another miracle you might appreciate is that the Nips targeted the Basilica housing the Santo Nino statue but the bomb fell through the roof without exploding, saving those sheltering inside and protecting a key piece of !Pinoypride history.

At this point I just support geoengineering !ifrickinglovescience !chemistry thoughts on stratospheric aerosol injection?

Jump in the discussion.

As an emergency response to survive? Yes.

But we would be altering the sunlight composition by some percentage, possibly altering plant life. Or maybe the aerosols only reflect infrared?

They'd need to not be liquid aerosols, but rather solid. Now you have to do the chemical pathway to their breakdown composition, their oxidation states, all based what type of environmental stressors they'd be put under.

But on the flip side, while this may help us to continue exponential population growth and consumption, if we don't change behavior at the same time then we would simply re-create the same problem and have to repeat aerosol injection in much less time.

If we did it smart, maybe, but it's like taking Ozempic and not changing your eating habits. Ur gonna get fat again.

CO2 emissions in the US peaked years ago and they probably peaked in China last year. Population growth will peak in the 2080s or possibly earlier thanks to the demographic transition but the population of the largest GHG emitters will decline decades before (the exception being the US). This however is not fast enough and we're already geoengineering so might as well try it.

Doesn't H2SO4 and SO2 from volcanic eruptions last for just a couple of years in the atmosphere before decomposing/falling as precipitation? Aerosol injection would need to be constant every 2 or 3 years.

If whatever humans are doing leveled off by noon tomorrow and everything is static -- incuding not needing to produce more food than we already do etc etc -- are you saying we would still need to inject aerosols every couple of years?

Even if you didn't mean that we'd still have to figure out the effects it has on reduced sun to plant life doing it just once.

I hate to be adventurous but we also need sulfur (two essential amino acids or else you can't live) so maybe the existence and occasional dispersal of sulfuric acid from volcanoes is just what the doctor ordered.

Idk maybe we can figure out some way to survive until the sun goes supernova.

Yes, because it is not static, it's not enough for GHG emissions to level on, they need to drop fast and that ain't happening. Plus, even if by some miracle we achieved net zero the planet will still warm a bit, CO2 takes a couple of decades to produce it's warming effect and there are other positive feedbacks (ice sheets melting means less sunlight gets reflected increasing temperature, permafrost melting releases methane which is a more potent greenhouse gas than CO2, despite having thankfully a half life of only 9 years)

This would have to be done continuously at around a thousand aircraft launches per year and ever growing due to GHGs still increasing.

It's the only solution that actually aligns with how humans behave. Telling people to not do something is a fool's errand. Humans are terrible at self-control, especially for anything that won't immediately help them personally. If we're going to fix this problem, we're going to do it by giving people work to do. Humans would rather spend 8 hours/day at the aerosol factory than drive their car a little bit less.

I have no idea what specific kind of geoengineering is best, but I'm sure its within our technological abilities to come up with something. The real problem is getting the whole planet to go along with it. It's not the CO2 that's the issue, it's the humans.

Well, the only feasible geoengineering method which would work is aerosol injection. This is proven as we know temperatures fall after a powerful volcanic eruption.

The problem is that it could have unintended consequences for the hydrological cycle, but tbf we're already geoengineering so might as well keep the temperature under control, another issue is that it doesn't reduce the CO2 concentrations, it merely reflects sunlight.

As for which countries would be on board, that's actually an easy answer, they don't need to agree, a country like the US or China could do aerosol injection unilaterally and without asking the rest.

unintended consequences

We're way past the point of no return on that. People need to grow up and realize that we've already lost so much in the last 10,000 years. All we can do is try to be less destructive when it's our turn. It's horrible but we'll get used to it, just like we got used to wiping out the megafauna and the buffalo and the forests and the great plains.

a country like the US or China could do aerosol injection unilaterally

:marseyletsgo:

This is really crucial, because there will be countries that for whatever reasons are benefiting from global warming. Maybe it thaws out their land. Maybe it lays waste to their enemies. If you can just pump stuff out faster than them it doesn't have to mean war.

Russia, lmao, once the permafrost melts away Siberia will become the largest extension of arable land in the planet.

I remember reading an article on the logistics of this type of geoengineering.

Basically it would require a fleet of high altitude planes (think the altitudes of the SR-71) dropping the aerosols, the article concluded that currently the only countries with the resources and technology to develop and afford such a project are the US, China, and maybe Russia and the EU. I think India will get there eventually.

There are also more benign geoengineering experiments like dehydrating the atmosphere as water vapor is also a greenhouse gas or pumping salt crystals to refelect sunlight (that experiment stopped because of protests against geoengineering lol).

The west doing this unilaterally would be a bit harder to pull off since there is a good chance the culture war would start center around this. If the left ends up pro and right countra, we might pull it off, but if wingcucks spontaneously align the other way around, it'll be doomed

wouldn't we need a totally different solution to deal w/ ocean acidification tho? I thought that was related to atmospheric co2 levels and NOT temperature (at least, not as much as co2 levels)

I might be making shit up tho tbh

Jump in the discussion.

No email address required.

The only way to stop ocean acidification long-term is by stopping emissions. That's another issue with geoengineering, it won't stop what's happening to the oceans, it doesn't solve climate change's underlying issues, it merely masks global warming. Also, atmospheric CO2 has a half-life of 120 years, and the CO2 dissolves into the oceans after that so acidification will still go on but at a slower rate compared to if we continue to pump it.

I don't know if it is relevant to Philippines, but I know 2 zoologists who are experts in invertibrates of the Indonesian/Papuan island region. Once a year they go into field to collect material, and they told me that that is the best part of their job- being able to go out into these remote islands, get to see the nature, interact with the locals etc. They said that they are always received well and asked to return again by the host villages. Naturally I asked if they visit same spots again, and they said that they do not simply because the areas become irrelevant from a biodiversity standpoint within the span of a couple of years. They know that there are likely more species to be found in the locales they've been to, but the development of land and growth of these villages in their absence would make this job harder than just picking a fresh spot few people have been to. Sad stuff.

It's not le tree hugging wholesome indians and bio-diversity loss :soysnoo3: what concerns me, it's the hydrological cycle. The moisture of the Amazon regulates the rains in the Southeast and the South, so the desertification of the Amazon will impact our beloved Paraná along our rivers and power generation.
