What does an acid trip typically feel like? Each person’s experience with acid will be different. Indeed, each trip may be different. One might be very light, but others can take a frightening and overwhelming turn. Symptoms may begin to show 20 to 90 minutesTrusted Source after taking a dose. The main episode can last several hours. Acid is a long-acting drug. It stays in the body 6 to 15 hoursTrusted Source. Most acid trips won’t last more than 9 hours. The trip During this period of “tripping” or active effects, you may begin to experience sensationalized perceptions of what’s happening around you. This can include “seeing” color or “tasting” sounds. Stationary items, like furniture, may begin to “move” or swell or shrink before your eyes. Coming down Coming down from the trip will feel like you’re gradually returning to Earth. Signs may begin to lessen in intensity. You may feel tired after getting through the hours-long trip and want to sleep. Afterglow An “afterglow” is possible for several hours after the end of the trip, too. This may feel like everything is “lighter” or “brighter” than before the trip. You may also have moments of flashbacks for several hours, even days, after the acid trip is over. Microdosing A microdose is a small dose of a psychedelic drug like LSD, often one-tenth of a normal dose. It’s sometimes used to help treat symptoms of anxiety and depression, but it’s not meant to completely encompass your day. However, little is known about the long-term effects of this practice.

This article goes over how nature can help us achieve our goal set forth by the paris climate agreement, which is to limit global temperature rise to less than 2 degrees celcius. If we are smart and careful we can use nature as our ally to help fight climate change. However if we are not so smart nature could hinder our fight with rising global temperatures and contribute ultimately to natures desctruction.

The Landry administration has canceled another major coastal restoration project — a sediment diversion planed for the Breton Sound marsh.
William H's comment,
October 17, 3:01 PM
This article highlights how Louisiana’s marshes are being affected by not receiving adequate nutrients due to the levees. It shows that not all management solutions are effective, as some can create new environmental problems. It’s surprising that canceling this project disregards scientific evidence. This demonstrates that coastal restoration often involves tradeoffs between ecological benefits, engineering feasibility, and funding priorities. Decisions like this can shape how communities adapt to sea-level rise and land loss over time. Comment written by Yaiza Delgado
Katheryn Galvez's comment,
October 17, 3:01 PM
It’s deeply concerning that the Mid-Breton Sediment Diversion was canceled. Especially given the drastic loss of wetlands that we are seeing and the fact that Louisiana set aside $8 billion for conservation projects from within the state. This tells us that funding clearly isn’t the issue, yet this marks the second major coastal restoration project halted by Governor Jeff Landry. These decisions undermine the Louisiana Coastal Master Plan at a time when rising sea levels and climate change are already threatening the region. It’s disheartening to see essential projects dismissed as “not important enough,” leaving us to wonder; when will protecting our coast finally become a priority, and will it be too late by then?

It's interesting to see this touted as rollback that would benefit indigenous communities in Alaska. If the Act previously allowed them an exception to the rule, then what does the new bill do to grant them more freedoms? That's definitely something I'd like to look up to understand. Otherwise, its sad we may see the return of more long line nets and whale drownings as a result.

Human water management contributes to sinking land across the globe, and it may also be responsible for an unexpected rise
John Maines's comment,
October 10, 12:28 AM
Who knew that depleting groundwater, then dousing it with rain, would cause the earth to rebound upward once the rain was gone? There are shifts with water happening at faster rates than replenishment can occur. I like that this article referenced the mismanagement and disappearance of our waters, creating the San Joaquin Valley, and how the earth sank in that instance, and how we are actively trying to balance the output with input by allowing storm drain water to be spread out over land to be reabsorbed. Maybe one day there will be less concrete on our earth's surface and more ground cover, so we can filter water the old-fashioned way!

Marine life washing up more frequently along California Coast
Mia Marie Uribe's insight:
I knew about the domoic acid poisoning that began late last year, I was unaware there were other illnesses that marine mammals were washing up with. Leptospirosis sounds like a bad tummy ache, but seems to do a lot more damage considering it attacks their kidneys and gastrointestinal track. For them to use the word "uninhabitable" describing the ocean and its current state, considering how much marine life is becoming ill either from HAB (harmful algal blooms like domoic acid), the warming ocean, food availability, or the heat "blob" forming, it really puts it into perspective how much damage has been caused. This makes me question whether the damage we've caused, as humans, is reversible or if we've permanently altered the future of marine ecosystems.
Kailani Franklin's comment,
October 9, 2:38 AM
This is really concerning news. It's so saddening to think about how this will affect marine life and ecosystems. There's so much intelligent life forms down in the ocean such as killer whales, bottlenose dolphins, and octopi who are being forced to live in almost uninhabitable conditions. All of these marine animals have the capability to feel deep emotions and form connections. Their intelligence may be different from humans and they may not be able to speak the same language as us but they are still sentient beings. It's so unfair the pain that is being done unto them just because humans are so caught up in their centeredness and are hell bent on upholding a system(capitalism) that only succeeds under exploitation.

Donald Trump was greeted with a giant sign stretched across Tel Aviv’s beachfront thanking him as he landed in Israel on Monday (13 October). The banner, showing the US president’s silhouette and the words “Thank you” and “home” in English and Hebrew, was positioned to catch his eye as Air Force One approached Ben Gurion Airport. Mr Trump’s visit comes as he marks what he calls a “historic” ceasefire deal between Israel and Hamas. The agreement includes the release of Israeli hostages and is being hailed as a potential turning point to end the war. Hours before landing, Trump declared: “The war is over.”
William H's insight:
I believe that this represents a good example of how the coast can be used in large and impactful ways to communicate messages from a community to the world. I have seen examples like this before in California multiple times and other states as well. Israel thanking President Donald Trump after his contributions to the release of the remaining Israeli hostages from Hamas and the end to the war on October 13, 2025 is the most recent example of this type of usage of a beach and the coast.

I agree, this represents a good example of how the coast can be used to communicate messages despite language barriers and not just ecological or recreational, but also cultural and communicative.

Marisol Pantoja's insight:
Researchers at Arizona State University collaborated with a team of coastal gillnet fishers to develop solar-powered lights that function as buoys. The net-illuminating gear effectively prevents sea turtles from entanglement in gillnets. I think this is an innovative conservation tactic

It's interesting to see this used as a deterrent for see turtles, but I wonder if fishing industries can use this same technology for attracting other things. I feel like this could be a good alternative light source for squid fishing. It doesn't seem to cause light pollution or light disturbance to other systems.

Hey David! This was a neat article and I believe it effectively raises alarm about the gravity of ocean acidification’s implications for Earth’s systems.

Timothy Whitfield's insight:
It's cool to see land trust NGOs becoming more and more common and prevalent, especially given how little wetlands are left in California. Apparently parts of the land will still be leased for agriculture, with others being restored to wetlands. The article also mentioned areas downstream being affected by floods, so restoration of wetlands would help mitigate that.

Marine heatwaves can jam the ocean’s natural carbon conveyor belt, preventing carbon from reaching the deep sea. Researchers studying two major heatwaves in the Gulf of Alaska found that plankton shifts caused carbon to build up near the surface instead of sinking. This disrupted the ocean’s ability to store carbon for millennia and intensified climate feedbacks. The study highlights the urgent need for continuous, collaborative ocean observation.
