". Â© Events like these may become all too common in the future, as fracturing and weakening of the ice increases. Thinning can destabilize the shelf because the ice loses contact with points on the ocean floor that strongly influence its grounding or stability. 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 â for example, a self-aware entity that believes it is a person in a world full of people, history, and particular physics. NY 10036. Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America. Pine Island Glacier calving events have increased in frequency in recent years.
- Do you have a gun at home?
- Do you have access to guns outside your home?
- Have you had a gun pulled on you over the last six months?
Ludwig Boltzmann. Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean â together discharging significant quantities of ice into the ocean. 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 ... ›. 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. Boltzmann Brains are hypothetical disembodied entities with self-awareness. 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. Future US, Inc. 11 West 42nd Street, 15th Floor, 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. 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 Pine Island Glacier (a.k.a. Scientists first detected a rift in the glacier in October 2011 during flights for NASA's Operation IceBridge. 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. worrisome on the heels of the above UN IPCC report, which basically tells us we're screwed unless we take drastic actionâand, I mean drasticâin order to curb emissions and slow the inexorable drift into an Earth that looks like one of those terrifying science fiction novels. The Pine Island Glacier is located around 1,600 miles from the tip of South America. Its ice loss has substantially increased over the last 25 years through thinning, acceleration and grounding line retreat. 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. There was a problem. 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. 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. Could patients and researchers benefit in similar ways? 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. Northwell Health isn't quite sure what that data will reveal. Thank you for signing up to Live Science. The Pine Island glacier in #Antarctica has finally calved, creating many large icebergs! You will receive a verification email shortly. New York's Northwell Health system recently received a $1.4 million grant for a new study on gun violence prevention. 11 February 2020. Calving events have occurred in â¦ 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. It is just the latest calving event for this rapidly shrinking glacier. Around this time, Pine Island Glacier started to shed smaller icebergs more frequently. The ice in the cave is melting, and studies on other possible collection events must occur soon before the evidence vanishes. Credit European Space Agency The ice broke off of Pine Island Glacier, which is the fastest melting glacier on the continent. This area is likely to continue to breakdown as Pine Island Glacier â¦ "
In the study, all conversations about firearm access and exposure will be confidential. âThe growing indentation into the shear margin was likely a factor in the formation of all the rifts that then caused PIGâs ice to fall apart in the last calving. 2040 J. E. Arndt et al. Scientists think the change in calving frequency is likely related to the thinning of the ice shelf. 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. Pine Island Glacier: the movie. "If you look at any other public health issue, it starts with this universal type of approach. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy (USN) air photos, 1960â66, and named by the Advisory Committee on Antarctic Names (US-ACAN) in association with Pine Island Bay. 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. 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. 2018: B-46 A huge iceberg just broke off of one of the most fragile glaciers in Antarctica. These two glaciers have been losing ice over the last 25 years. Pine Island Glacier Calving (WMS) The Pine Island Glacier is the largest discharger of ice in Antarctica and the continent's fastest moving glacier. Large calving events used to take place at Pine Island Glacier every four to six years, but theyâre now a nearly annual occurrence. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. "So, how can we target screening if we don't even know the basic elements of a public health approach?" But what's concerning about Pine Island Glacier is that it's calving icebergs more frequently than it used to, Lhermitte said. pic.twitter.com/iubE8JffVRFebruary 10, 2020. The goal is to destigmatize doctor-patient conversations about guns, and reframe gun violence as a public health issue. 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". The size of this one, however, is about 15% bigger than the last. Two large rifts in PIG were spotted in 2019 and scientists have kept a close eye on the cracks and changes. It's got planetary bodies of various shapes and sizes. This iceberg, called B-21, is 42 kilometers by 17 â¦ This mind-churning idea proposes that the world is quite possibly just an effect of your disembodied consciousness and doesn't really exist.,
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. 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. It may be more likely for a Boltzmann Brain to come into existence than the whole Universe. As a result, the Pine Island and Thwaites ice shelves are retreating inland faster than new ice can form. Vote like your lives depend on it, folks.
The answers will become part of a large, anonymized data pool that will help researchers better understand the underlying factors behind gun violence. 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. And your sense of self is just a statistical fluctuation. The big calving event is one of a handful that have occurred in the past two decades. "There's a tremendous amount of insight that can be plumbed using these various substances. By gathering data on changes to ocean temperature and increasing surface melt rates, researchers are working toward implementing the physics of calvingâa calving lawâin computer simulations. New York, PIG) The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers. 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. "
Debates of the idea persist, however, especially as it is hard to disprove. In the last decade, huge chunks of the glacier calved away in 2011, 2013, 2015, 2017, 2018 and now in 2020. The close up shows a piece of pottery next to burned pieces of wood. 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. By Please refresh the page and try again. 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). 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. âAlthough iceberg âcalvingâ 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,â says Alison Banwell, a glaciologist at CIRES, University of Colorado, Boulder. 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:That's the 2017 calving, in a GIF created by Stef Lhermitte. It's about to do it againâand this one is 15% bigger than the last, at 115 square miles. 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. 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. 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. Pine Island Glacier is the largest current Antarctic contributor to sea-level rise. 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. It's the same glacier that calved in September 2017, losing an iceberg 4.5 times the size of Manhattan. It has laws like an arrow of time that seems to be flowing only in one direction. And it will release twice as much carbon into the atmosphere as exists today. A large iceberg has finally separated from the calving front of Antarctica's Pine Island Glacier. The dates of their collection activities line up with tree-ring records of drought events in the area. It's the sixth large-calving event from this glacier since 2001. 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. After all, doctors can use that information to design better treatments. 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. 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. Scientists worry that Pine Island and the neighboring Thwaites 'Doomsday' Glacier could be headed toward collapse.

Over the past 8 years, the Pine Island glacier is losing about 58 billion tons of ice per year. That's why universal screening is the first step.The increase in these events is indicative of the warming water in Pine Island Bay. Calving Icebergs Pine Island Glacier ice shelf periodically calves huge icebergs. From Oct 2014 to recent calving in 108 #sentinel1 images @CopernicusEU @ESA_EO pic.twitter.com/oYKvelCKPd. "As the planet warms from 1.5Â°C to 2Â°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.
A new study from Northwell Health, the largest health system in New York State, aims to find out. The study tasks doctors with asking all patients about their access and exposure to guns, and recommending interventions and safety tips as needed. In West Antarctica, Pine Island Glacier and Thwaites Glacier have been melting at alarming rates, according to satellite imagery over the ice continent. The ice block the core was taken from, still covered in ashes. In the "We Ask Everyone. A mind-bending paradox questions the nature of reality. 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. This âuniversal screeningâ study will find out. About one year ago, in Antarctica, the Pine Island Glacier
The collected data will help health professionals develop better models for predicting who's most at risk of gun violence.
"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. A huge iceberg just broke off Antarctica's Pine Island Glacier Gun violence is a public health crisis that is notoriously difficult to study because of politics. Scientists at Copernicus, the European Unionâs Earth observation program, have been closely monitoring the glacier since large cracks appeared near its edge in October 2019. 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. 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). Pine Island's newest icebergs calved just days after scientists reported the hottest temperature ever recorded in Antarctica. 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? Scientists find routes using arches of chaos that can lead to much faster space travel. Abstract. 5. That could set off unstoppable retreat of Pine Island Glacier. According to NASA, the region around the two glaciers contains enough vulnerable ice to raise the ocean by 4 feet (1.2 meters). Mortality rate vs funding for 30 leading causes of death in the United States.
Doctors often ask patients about the health risks in their daily lives, such as sugar intake or tobacco use. The irreversible collapse of the West Antarctic ice sheet would raise sea levels 20 feet, says the UN. A large calving event on Pine Island Glacierâs ice shelf in February 2020, observed from the Corpernicus satellite. But all this amazing amount of varied matter is also very hard to pull off, requiring a tremendous amount of energy. 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. 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. Check out these #Sentinel1 ️ captures from yesterday 09 Feb., last week 05 Feb. and 01 Oct., 4 months ago, when large cracks became apparent. âWhen Pine Island Glacier lost contact with the thicker ice of the southwest tributary it was like the loss of protection on the glacierâs flank,â said NASA/UMBC glaciologist Christopher Shuman. This phenomenon of calving isn't new for Pine Island Glacier, according to the ESA. It's doubly (trebly?!) Having been repressed in the 1960s for their ties to the counterculture, psychedelics are currently experiencing a scientific resurgence. There's also a lot of risks there, as with most valuable things," says artificial intelligence researcher Ben Goertzel. Firearm Safety is a Health Issue" research study. It also has us, humans, nature's supreme creations (at least according to us). 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. The Pine Island glacier "is one the fastest-retreating glaciers in Antarctica." The idea highlights a paradox in thermodynamics. Visit our corporate site. : 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).
So, what if doctors began asking similar questions about guns, which are involved in more than 100 deaths in the U.S. every day? Please deactivate your ad blocker in order to see our subscription offer. 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. Can hospitals prevent gun violence? The loss of large ice chunks, known as calving, is a routine process that happens to every glacier. 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. The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers.

By July 2013, infrared and radar images indicated that the crack had cut completely across the ice shelf to the southwestern edge. 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 â¦ These events are happening at a quickening pace, and there are signs the ice theyâre unleashing is getting weaker. 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.
