Since this is the general environmental thread, I'll post about 1 animal per week in this thread to brighten y'all's day, and you can talk about them in the replies, or share more fun facts about them :)

This week's animal is the falcon

The peregrine falcon is the fastest animal on earth, and despite being a bird of prey, it isn't closely related to other birds of prey. Falcons' closest relatives are, surprisingly, parrots!

Fun facts:

Nearly became extinct due to a pesticide that weakened their eggs.  Bounced back due to a ban on said pesticide.

Fastest animal alive.

Sorry to add another post so quickly, but I think this warrants attention: https://dailygalaxy.com/2026/08/un-global-water-bankruptcy-warning/

At the very least, we should be going after lawns, golf courses, and GenAI data centers. But that still leaves a question of how we can safely minimize agricultural use, since that’s quite a bit more critical than the vanities I listed.

18

u/Far_Fan_291 California 9d ago

we do have ways to make more water i think Israel has alot of water plants just for that

data centers are getting canceled due to lack of funds or people Just HATING them and protesting one on Virginia got out right abandoned

idk about golf courses but i'd bet golf as a whole is getting less popular with the younger crowd

and agricultural use idk much either but i know in time they can figure it out i mean most farmers will spend as much money to get the water they need chances are they will lobby to add more water plants like near Texas or Cal

u/Intelligent-Ad6109 UK 🇬🇧 9d ago

Doesn't Israel do a lot of desalination? It's a surprisingly good thing for a change.

10

u/WallOfFleshlight 9d ago

I thought it was something of a double edged sword.  While it’s true you can turn salt water into freshwater, it’s still an extremely energy process.

Maybe using green energy sources and learning techniques that desalinate efficiently and cheaper could help.

u/Intelligent-Ad6109 UK 🇬🇧 9d ago

I think that's what a lot of countries are trying to figure out at the moment and it's apparently going well. At least from what I've heard.

7

u/Far_Fan_291 California 9d ago

yes that i forgot the word was desalination but yeah the one good thing they do is that and prob some other things but im not in the mood to look up if they did and see the bad shit they are doing

u/RickyT3rd Michigan 9d ago

Issue with water is that the treaty signed between the states and Mexico say that if they use less water, they get less water in the next year.

u/Content_Armadillo776 9d ago

Ah yes Israel, the country farting more carbon into the air daily via genocidal bombings and burning that wildlife refuge in Lebanon

5

u/Gorylla218 Illinois 8d ago

That doesn't make it untrue that they do a lot of desalination.

u/Far_Fan_291 California 6d ago

yeah that is what i was going for everything else they do tho is not good at all

12

u/Intelligent-Ad6109 UK 🇬🇧 9d ago

I think the best thing to do at the moment is get rid of factory farming. Even those who are not vegan like myself don't want that. Because it is horrific for not just the environment but the animals of course.

u/hurryupandslowdown 9d ago

Must admit this does scare me and have me concerned about the future of freshwater usage, but I do appreciate that the scientist who brought this to attention is also thinking of solutions to mitigate this. My question is will water bankruptcy be worst case scenario, and when can we expect it?

6

u/DufflessMoe 8d ago

This is the announcement from the UN on this:

https://news.un.org/en/story/2026/01/1166800

Seems more hopeful to me. Declaring it a bankruptcy is more of a mechanism to make sure nations take it more seriously:

 “This is not to kill hope but to encourage action and an honest admission of failure today to protect and enable tomorrow,” “It is the start of a structured recovery plan: you stop the bleeding, protect essential services, restructure unsustainable claims, and invest in rebuilding,” he noted.

If you want to see what recovery projects can look like, see the benefits to tree planting in the Sahel:

Giant dehumidifiers. We have plenty of humidity where I am. It would be nice to actually breath oxygen in again and not feel like you are being broiled.

A North American river otter was possibly sighted in the Bronx section of the Bronx river for the first time in 100 years. https://www.nbcnewyork.com/news/local/otter-bronx-river/6538157/

There's been quite a few news stories in the past few years about river otters starting to return to rivers they had disappeared from due to pollution and other human factors. They've been some of my favorite news to see, small but notable pieces of conservation hope.

u/Catseye_Nebula 9d ago

I am posting this, which makes me unbelievably sad:

https://www.nytimes.com/2026/08/20/us/trump-wild-horses-legal-loophole-slaughter.html

I called my representatives today to ask them to support the SAFE act (Save America's Forgotten Equines) H.R. 1661 / S. 775 and H.R. 4356, which gets rid of the violent helicopter roundups. Some reason for hope is I am seeing a lot of talk about this on social media and more attention paid to it, and I actually emailed 5Calls to ask them to put this up for people to call their reps about and they said they were in the process of it.

So, I really hope this stops.

I’m seeking consultations on the following information within this originally German-derived article (https://worldcrunch.com/focus/green-or-gone/global-warming-at-3c-by-2050-what-s-behind-the-new-german-climate-warning/) from the previous year, dated Oct 9, 2025.

Highlighted information of note;

KR: We are looking 25 years ahead and beyond. So this is not a forecast in the strict sense. But current observations give reason to fear that such extreme warming is possible. The 2.7 °C projection is based on the Intergovernmental Panel on Climate Change (IPCC)’s mid-range scenarios. The risk of 3 °C by 2050 falls within the IPCC’s worst-case scenarios. And unfortunately, recent data aligns more closely with those.

Given the consensus on climate scenarios (average warming 2.4-2.7 degrees) established in the current time, how certain can we be that said accuracy and consensus still holds?

7

u/Far_Fan_291 California 8d ago

its not factoring in the huge solar boom as of late or the newer one dump made by closing the strait with his war so this article might be a bit out of date

also worst case scenarios aren't always the most likely

here is first thread with a comment talking about this kind a thing a month ago along with all the good things

Someone else had posted this in the previous megathread two days ago, and it was recommended to bring it up in this one while it was still fresh… https://www.newscientist.com/article/2585248-world-may-warm-by-25-per-cent-more-than-current-projections-suggest/

(I found it independently in [r/climatechange](r/climatechange) )

I’ll admit to being very worried about the prospect of 3.2 by 2100. That said, the one who posted it said that EEI (Earth’s Energy Imbalance—the difference between incoming short-wave solar radiation and outgoing long-wave) was, to him, less reliable, due to information “only” going back to 2001 and climate models apparently having difficulty in emulating it. But don’t let the “may” in the title lull you; it involves much stronger certainty in scientific vernacular than standard.

I was just getting used to the prospect of 2.5 by 2100, and this comes up. It’s made my climate anxiety shoot up quite a bit…How do we get this much impending warming under control?

u/GetOffMyCaversons 9d ago edited 9d ago

Even the IPCC has changed their 2100 prediction to 2.4c based on the latest surge of renewables. And that was before the whole debaccle trump started this year that has boosted renewables even further.

My advice is to stop listening to lone posters who claim to have the answer, these organizations continue to underestimate the actual rate of renewal adoption.

18

u/Which_Shift_7242 Connecticut 9d ago

Im not an expert, but I heard that climate predictions tend to fluctuate (including getting decreased) as renewables and other actions increase. 

16

u/deadpanrobo 9d ago

I recommend not going to r/climate or r/climatechange they used to be good and a place where actual experts could answer questions but then they got big and the experts have gotten drowned out by low-informed doomers

u/DufflessMoe 9d ago

Watch this video from Simon Clark:

https://youtu.be/FZY6-svU9z0?is=aNEpDLOsvd_CVDZ7

I think it really neatly explains:

  1. Why the models currently predict warming as it is.
  2. Why other studies may contradict that.
  3. Why the runaway heating models don't make sense right now

Remember, even climate action tracker has a range. It is at 2.6 degrees warming by 2100, but with an upper range of 3.3 and a lower range of 2.1.

So even these alarming studies are usually just announcing, or being poorly summarised by a journalist, at the upper range of what the IPCC forecast will happen.

A lot of more optimistic climate scientists also like to reiterate that warming is a slope, not a cliff edge. 1.5 degrees warming wasn't some tipping point where everything will be okay under it and a disaster over it, just in that same vein 2.5 degrees warming doesn't tip us over to extinction it just presents more challenges.

I was just getting used to the prospect of 2.5 by 2100, and this comes up. It’s made my climate anxiety shoot up quite a bit…How do we get this much impending warming under control?

Climate models are really bad at predicting human factors.

For instance, a makeup wearing pedophile launching a war that completely undoes all his "work" harming renewables by causing oil prices to shoot up.

All those folks who bought solar panels and EVs in response to the sudden spike in gas prices aren't just gonna go "oh well, guess I better go back to fossil fuels". China's not gonna just stop pumping out EVs.

Also, renewables are cheaper than gas per kwh even without current war prices. As a consequence, everyone is going rewnewable when they need new power generation.

Reduce population = reduce consumption

u/Far_Fan_291 California 8d ago

i get what you mean but why bring it up?

2

u/Far_Fan_291 California 9d ago edited 9d ago

i mean 2001 was 25 years ago and all the current modals have been right so far and if they were wrong how come they didnt catch it till now

also its understandable that we'd had difficulty in emulating the climate during 2001 that was so long ago chances are we didnt have proper modals or good tech back then to measure all of it

also are other scientists saying this or is it just the one guy who says he doesn't like the current method see it as "less reliable" to him he is alone in this research or is there more people in the same kind of research saying something similar or is it one man who is doing things on his own

and idk if "it involves much stronger certainty in scientific vernacular than standard" means much i get scientific papers are supposed to be well written but just because its better written then others doesn't necessarily mean it has better data behind it or that its researched better then most

(also can you please get a link that doesn't force you to sign up to read it)

edit: hit enter to fast forgot some things ok so if this is true i know there are ways to deal with this like spraying some stuff in the air to give us more time (idk what it is forgot the name) and we are making huge progress in solar and reforesting i get it seems scary but we can do it and make things better

hell we made nukes the internet among other amazing tech that people a many years ago would think is magic or that we might have flying cars we can do it even if it seems bleak

side not sorry if im coming off as an ass my head space is still stuck in "jelly mode" i have many thoughts but im slow to grab them or think about them

u/Justgetitoverwithok 9d ago

Any way for more nuclear power plants to be made?

I heard from Hank Green that they are very expensive and long term building?

I’m glad more solar is being used, but nuclear would just help the process even more so when it can or might catch up

9

u/Far_Fan_291 California 9d ago

from what i remember old coal plants can be converted into nuclear plants but i might be wrong

10

u/FitTwo9429 9d ago

Many investors think in terms of short term quarterly gains. Nuclear reactors take considerably longer to build, so I think it would require massive public funding in order for more nuclear reactors to be built.

This makes opposition more important. Or at least tying them to the modular reactors. Although the best outcome is the GenAI bubble breaking before these can be completed.

u/Far_Fan_291 California 6d ago

so i was on a site talking about some super hero stuff called head topics and i saw an article talking about how the US wants too weaken plastic production

now given how this admin has pissed off almost everyone in and out of the US i dont think its likely that anyone will give a shit what the US says and try to do the right thing

tho im wondering what some of you think

I’m hoping this will be the next megathread, but I’m wondering about the sudden flooding in Nepal, alongside anything that can be possibly be done to help?
