There is a stigma surrounding psychedelic drugs that some scientists and researchers argue is undeserved. Are you a Boltzmann Brain? This is of particular concern in the case of Pine Island and Thwaites Glaciers and adjacent glaciers in the Amundsen Sea sector of the West Antarctic Ice Sheet. The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. Live Science is part of Future US Inc, an international media group and leading digital publisher. After all, doctors can use that information to design better treatments. Calving Icebergs Pine Island Glacier ice shelf periodically calves huge icebergs. Pine Island's newest icebergs calved just days after scientists reported the hottest temperature ever recorded in Antarctica. A huge iceberg just broke off of one of the most fragile glaciers in Antarctica. Pine Island Glacier is the largest current Antarctic contributor to sea-level rise. According to NASA, the region around the two glaciers contains enough vulnerable ice to raise the ocean by 4 feet (1.2 meters). Finally, a new research initiative has the green light to collect life-saving data. Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss.

When we reframe [gun violence] as a public health issue, then we're able to use the same strategies that we've used to decrease car-crash deaths, decrease infections and deaths from HIV, and reduce injuries and deaths from a host of other problems.
,

The paradox of the Boltzmann Brain can really pull the rug from under you if you follow it to all of its logical and illogical extents. The dates of their collection activities line up with tree-ring records of drought events in the area. About one year ago, in Antarctica, the Pine Island Glacier

The answers will become part of a large, anonymized data pool that will help researchers better understand the underlying factors behind gun violence. It calved a large iceberg in 2001, and in 2011 a huge rift developed on the ice shelf. worrisome on the heels of the above UN IPCC report, which basically tells us we're screwed unless we take drastic action—and, I mean drastic—in order to curb emissions and slow the inexorable drift into an Earth that looks like one of those terrifying science fiction novels. The fact that the United States has gone the opposite direction, abandoning the Paris Accord and even calculating a rise of 7 degrees (F) as acceptable and even inevitable when working on new automobile emission standards is contributing to a looming climate change catastrophe by 2040. The ice broke off of Pine Island Glacier, which is the fastest melting glacier on the continent. Because ice at the edge of the glacier was already floating, this ice will not directly contribute to sea level rise when it inevitably melts. Having been repressed in the 1960s for their ties to the counterculture, psychedelics are currently experiencing a scientific resurgence. Thinning can destabilize the shelf because the ice loses contact with points on the ocean floor that strongly influence its grounding or stability. The calving mechanism of tabular icebergs is one of the major unknowns in glaciology and hence calving events at locations where the glaciological variables of ice shelves or ice tongues are well known are ideal natural setups for studying these mechanisms. Case in point - the notion that we may be living in a simulated reality, propagated by luminaries like Elon Musk and Neil deGrasse Tyson.

, Sponsored by the Institute for Humane Studies, Huge Iceberg Poised to Break Off Antarctica's Pine Island Glacier ›, A Giant Iceberg in West Antarctica Is Disintegrating, And Scientists ... ›. The increase in these events is indicative of the warming water in Pine Island Bay. Calving events have occurred in … In West Antarctica, Pine Island Glacier and Thwaites Glacier have been melting at alarming rates, according to satellite imagery over the ice continent. "If you look at any other public health issue, it starts with this universal type of approach. It's about to do it again—and this one is 15% bigger than the last, at 115 square miles. Pine Island Glacier Calving (WMS) The Pine Island Glacier is the largest discharger of ice in Antarctica and the continent's fastest moving glacier. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy (USN) air photos, 1960–66, and named by the Advisory Committee on Antarctic Names (US-ACAN) in association with Pine Island Bay. Its ice loss has substantially increased over the last 25 years through thinning, acceleration and grounding line retreat. New York's Northwell Health system recently received a $1.4 million grant for a new study on gun violence prevention. If the West Antarctic ice sheet collapses, it will mean a 20-foot rise in sea levels. Recently, the frequency of Pine Island Glacier calving events has increased. It's the sixth large-calving event from this glacier since 2001. The ice shelf currently loses around 62.3 ± 5 Gigatonnes per year of ice through calving, and loses 101.2 ± 8 Gigatonnes per year through basal melting 24. calved an iceberg about 100 sq. How they work is not completely understood, but the empirical evidence shows promise in the fields of curbing depression, anxiety, obsession, and even addiction to other substances.

A new study from Northwell Health, the largest health system in New York State, aims to find out. Yesterday, those cracks finally cut a chunk of the glacier away (a process known as calving), releasing a giant jigsaw puzzle of fresh icebergs into the nearby Amundsen Sea. And on a larger scale, health professionals can use anonymized medical data on substances like sugar and tobacco to learn more about diseases like diabetes and lung cancer.

There's also a lot of risks there, as with most valuable things," says artificial intelligence researcher Ben Goertzel. pic.twitter.com/iubE8JffVRFebruary 10, 2020. Could patients and researchers benefit in similar ways?

Abstract. That could set off unstoppable retreat of Pine Island Glacier. The ice block the core was taken from, still covered in ashes. Firearm Safety is a Health Issue" study, which began in September, doctors will ask every patient who visits an emergency department at three Northwell Health facilities about their access and exposure to firearms, with questions like:

By July 2013, infrared and radar images indicated that the crack had cut completely across the ice shelf to the southwestern edge. Visit our corporate site. The previous record was 63.5 F (17.5 C), set in March 2015. There is nothing really there but your self-awareness.

These types of entities have been dubbed "Boltzmann Brains" by modern physicists Andreas Albrecht and Lorenzo Sorbo. They did not claim to such brains really being in existence but rather used the idea to point out the absurdities and limitations of taking the idea of thermodynamic fluctuations to their extent.

Boltzmann Brains have also been criticized as philosophical paradoxes that are experientially unprovable. "As the planet warms from 1.5°C to 2°C, the risks grow rapidly for some very dangerous tipping points, including the irreversible collapse of the West Antarctic ice sheet (which would raise sea levels 20 feet)," reads the UN's recent IPCC Report. There is a lot we don't know about psychedelics, but what we do know makes them extremely important. Re: Pine Island Glacier (PIG) Calving and Discussion « Reply #2593 on: November 18, 2020, 03:57:37 PM » I post an animation based on the SIS images of 06/11, 12/11 and 18/11 to show the rapid evolution of WmR4 (especially in the last 6 days). This area is likely to continue to breakdown as Pine Island Glacier … Over the past 8 years, the Pine Island glacier is losing about 58 billion tons of ice per year. In this video, Michael Pollan, Sam Harris, Jason Silva and Ben Goertzel discuss the history of psychedelics like LSD and psilocybin, acknowledge key figures including Timothy Leary and Albert Hoffman, share what the experience of therapeutic tripping can entail, and explain why these substances are important to the future of mental health. NASA reports that these events used to take place on four to six year intervals, however, calving of the glacier has become a yearly occurrence. The study tasks doctors with asking all patients about their access and exposure to guns, and recommending interventions and safety tips as needed. Pine Island Glacier, one of the fastest-shrinking glaciers in Antarctica, has just lost another huge chunk of ice to the sea, continuing a troubling trend that has become a near-annual occurrence in the last decade. On its own, the recent calving event is not entirely surprising or particularly threatening to global sea levels; calving is a normal part of life for ice formations with sections that float on the water, according to NASA's Earth Observatory. We know that generally things tend to fall apart and decay.

What the influential Austrian physicist Ludwig Boltzmann (1844-1906), one of the founders of the field of thermodynamics, hypothesized is that while the entropy of a system (its measure of disorder) always increases (moving towards disorder), there is some tiny possibility that a fluctuation can bring a system from disorder to order. Mortality rate vs funding for 30 leading causes of death in the United States. : Bathymetric controls on calving processes at Pine Island Glacier shelves downstream of the grounding line have a buttressing effect on the grounded portion of marine-based ice streams and, therefore, are an important factor in maintaining the up-stream glacier stability (Schoof, 2007; Gudmundsson, 2013). And your sense of self is just a statistical fluctuation. Events like these may become all too common in the future, as fracturing and weakening of the ice increases. The goal is to encourage firearm safety, educate at-risk patients on violence-prevention resources, and normalize doctor-patient conversations about guns—not stigmatize gun ownership or infringe upon individual rights.

Future US, Inc. 11 West 42nd Street, 15th Floor, It's doubly (trebly?!) The Pine Island glacier in #Antarctica has finally calved, creating many large icebergs! “The growing indentation into the shear margin was likely a factor in the formation of all the rifts that then caused PIG’s ice to fall apart in the last calving. Around this time, Pine Island Glacier started to shed smaller icebergs more frequently. In the last decade, huge chunks of the glacier calved away in 2011, 2013, 2015, 2017, 2018 and now in 2020. "So, how can we target screening if we don't even know the basic elements of a public health approach?" The close up shows a piece of pottery next to burned pieces of wood. Check out these #Sentinel1 ️ captures from yesterday 09 Feb., last week 05 Feb. and 01 Oct., 4 months ago, when large cracks became apparent. This ocean warming has increased the melting and calving (the breaking off of ice chunks) of Pine Island and Thwaites glaciers, studies show, while declining of … Two large rifts in PIG were spotted in 2019 and scientists have kept a close eye on the cracks and changes. By gathering data on changes to ocean temperature and increasing surface melt rates, researchers are working toward implementing the physics of calving—a calving law—in computer simulations. A photo from Europe's Copernicus Sentinel-2 satellite shows two gargantuan cracks forming along the edge of Antarctica's Pine Island Glacier, one of the fastest-shrinking glaciers on the continent. Even so, when a large crack formed across the glacier in mid 2000, it was surprising how fast the crack expanded, 15 meters per day, and how soon the resulting iceberg broke off, mid-November, 2001. Credit European Space Agency Pine Island Glacier calving events have increased in frequency in recent years. Specifically, the accompanying image (from the website) illustrates how rifting (cracking) of the Pine Island Ice Shelf, PIIS, has increased from 1973 to 2011, while comparing the shape of the 2011 calving face with the current calving face (see prior posts in this thread), shows how rapidly the calving has accelerated in the past two years (as compared to the 1973 to 2011 period). New York, "

In the study, all conversations about firearm access and exposure will be confidential. 2018: B-46 Boltzmann Brains are hypothetical disembodied entities with self-awareness. Firearm Safety is a Health Issue" research study. Can hospitals prevent gun violence? That's why universal screening is the first step.

While large calving events used to occur at Pine Island Glacier every four to six years, they've now become a near-annual occurrence, according to NASA. 11 February 2020. The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers. This mind-churning idea proposes that the world is quite possibly just an effect of your disembodied consciousness and doesn't really exist. Pine Island Glacier (PIG), in the West Antarctic Ice Sheet, has an area of 175,000 square kilometres and loses about 45 billion tons of ice each year. Northwell Health isn't quite sure what that data will reveal. The loss of large ice chunks, known as calving, is a routine process that happens to every glacier. Please refresh the page and try again. Scientists think the change in calving frequency is likely related to the thinning of the ice shelf.

The collected data will help health professionals develop better models for predicting who's most at risk of gun violence. Large calving events used to take place at Pine Island Glacier every four to six years, but they’re now a nearly annual occurrence. And it will release twice as much carbon into the atmosphere as exists today. These events are happening at a quickening pace, and there are signs the ice they’re unleashing is getting weaker. 2040 J. E. Arndt et al. miles in size—4.5x the size of Manhattan. He and others believe that by making psychedelics illegal, modern governments are getting in the way of meaningful research and the development of "cultural institutions to guide people in really productive use of these substances. Scientists first detected a rift in the glacier in October 2011 during flights for NASA's Operation IceBridge. It also has us, humans, nature's supreme creations (at least according to us). The irreversible collapse of the West Antarctic ice sheet would raise sea levels 20 feet, says the UN. While large calving events used to occur at Pine Island Glacier every four to six years, they've now become a near-annual occurrence, according to NASA. This is doubly worrisome on the heels of the recent UN climate change report, which gave humanity an urgent deadline to cut carbon emissions: just 12 years. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. The big calving event is one of a handful that have occurred in the past two decades. © Vote like your lives depend on it, folks. Scientists worry that this persistent retreat could be a sign that a runaway melting cycle is in effect: As comparatively warm sea water laps at the newly exposed edges of an ice shelf, melting accelerates, the ice shelf stretches and thins, and further calving becomes ever more likely. Scientists at Copernicus, the European Union’s Earth observation program, have been closely monitoring the glacier since large cracks appeared near its edge in October 2019.

Doctors often ask patients about the health risks in their daily lives, such as sugar intake or tobacco use. Today, the glacier is observed to be losing mass by a combination of calving events together with strong basal melting, where warm ocean currents erode the underside of the floating ice shelf.

Ludwig Boltzmann.

"This will be the first research study to universally screen all patients who come into the emergency department for firearm access, and gun violence risk, and then intervene as needed, with gun safety counseling, gun locks, community resources, and medical referrals," said Dr. Chethan Sathya, director of Northwell's Center for Gun Violence Prevention. The Pine Island Glacier (a.k.a. The idea highlights a paradox in thermodynamics. Pine Island Glacier: the movie. After all, if you were a Boltzmann Brain, everything that you could come up with to prove or disprove it would likely be because of the hallucinations your consciousness is having.

Other types of solipsistic thinking have also entered our culture. It's got planetary bodies of various shapes and sizes. That's the 2017 calving, in a GIF created by Stef Lhermitte. Scientists worry that Pine Island and the neighboring Thwaites 'Doomsday' Glacier could be headed toward collapse. But such a person - let's say you - is only full of all the knowledge and experiences because you are made that way by the fluctuation that created you. A large calving event on Pine Island Glacier’s ice shelf in February 2020, observed from the Corpernicus satellite. The goal is to destigmatize doctor-patient conversations about guns, and reframe gun violence as a public health issue. These two glaciers have been losing ice over the last 25 years. Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America. The ice in the cave is melting, and studies on other possible collection events must occur soon before the evidence vanishes. It has laws like an arrow of time that seems to be flowing only in one direction. However, over the past two decades, calving events have been occurring much more frequently at Pine Island Glacier and the neighboring Thwaites Glacier (also known as the "Doomsday Glacier") as the surrounding ocean warms due to global warming. Published on Sep 25, 2017 Antarctica just lost another huge piece of ice. Gun violence is a public health crisis that is notoriously difficult to study because of politics. From Oct 2014 to recent calving in 108 #sentinel1 images @CopernicusEU @ESA_EO pic.twitter.com/oYKvelCKPd. This ‘universal screening’ study will find out. On Thursday (Feb. 6), temperatures near a research base on the continent's northern edge reached 64.9 degrees Fahrenheit (18.3 degrees Celsius), the World Meteorological Organization reported. NY 10036. It's the same glacier that calved in September 2017, losing an iceberg 4.5 times the size of Manhattan. But all this amazing amount of varied matter is also very hard to pull off, requiring a tremendous amount of energy. For ocean-terminating glaciers like Pine Island Glacier the calving process takes place in a floating ice shelf where stresses like wind and ocean currents cause icebergs to break off. The Pine Island glacier "is one the fastest-retreating glaciers in Antarctica." Brandon Specktor - Senior Writer "

Debates of the idea persist, however, especially as it is hard to disprove. It is just the latest calving event for this rapidly shrinking glacier. A large iceberg has finally separated from the calving front of Antarctica's Pine Island Glacier. Northwell Health will also offer interventions to at-risk patients.

The Pine Island Glacier is located around 1,600 miles from the tip of South America. Please deactivate your ad blocker in order to see our subscription offer. Photo by Mario Tama/Getty Images. “Although iceberg ‘calving’ from floating Antarctic ice shelves is a natural, ongoing process, the recent calving event of Pine Island Glacier was particularly large and such calving events from this glacier appear to be becoming more frequent,” says Alison Banwell, a glaciologist at CIRES, University of Colorado, Boulder. Related: Today’s climate change is worse than anything Earth has experienced in the past 2,000 years. A huge iceberg just broke off Antarctica's Pine Island Glacier What's even more concerning about the Pine Island Glacier's calving event is that it happened right next to the Thwaites Glacier, which is so at risk it's called the "Doomsday Glacier". Several experiments over the past decades have shown that, when used correctly, drugs like psilocybin and LSD can have positive effects on the lives of those take them. It may be more likely for a Boltzmann Brain to come into existence than the whole Universe. PIG) The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers. In total, the icebergs measure about twice the size of Washington, D.C., in area (more than 130 square miles, or 350 square kilometers), according to The Washington Post. 1901

From the physicist's work it follows that it would be more likely for random quantum fluctuations in nature to create something simpler than our astounding Universe – for example, a self-aware entity that believes it is a person in a world full of people, history, and particular physics. Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean – together discharging significant quantities of ice into the ocean.

So, what if doctors began asking similar questions about guns, which are involved in more than 100 deaths in the U.S. every day? You will receive a verification email shortly. Thank you for signing up to Live Science. "There's a tremendous amount of insight that can be plumbed using these various substances. A new study shows that ancient peoples in the American Southwest were using the same caves to collect ice for a millennium. ". A mind-bending paradox questions the nature of reality. The size of this one, however, is about 15% bigger than the last. The Caltech theoretical physicist Sean Caroll called them "cognitively unstable: they cannot simultaneously be true and justifiably believed" in his 2017 paper "Why Boltzmann Brains Are Bad. But what's concerning about Pine Island Glacier is that it's calving icebergs more frequently than it used to, Lhermitte said. There was a problem. 5. This iceberg, called B-21, is 42 kilometers by 17 … Dr. Sathya and Mr. Dowling are spearheading Northwell's gun-violence prevention efforts, including the "We Ask Everyone.

"The bottom line is, we don't know the answers yet," said Dr. Sathya. This phenomenon of calving isn't new for Pine Island Glacier, according to the ESA. “When Pine Island Glacier lost contact with the thicker ice of the southwest tributary it was like the loss of protection on the glacier’s flank,” said NASA/UMBC glaciologist Christopher Shuman. It's something that is more likely to come into existence by chance than the Universe that would have had to produce it.

,

So are you really a Boltzmann Brain? Let's look at the underlying thinking.

Our Universe is extremely vast and complex, still filled with as much of the unimaginable as what we have already figured out. As a result, the Pine Island and Thwaites ice shelves are retreating inland faster than new ice can form.
