Hundreds Of Dead Loggerhead Turtles Wash Up On Same Coastline As Mass Sea Lion Beachings

Dead Loggerhead Turtle

By Anthony McLennan / Truth Theory

Following the discovery of 137 dead sea lions earlier this month in northwestern Mexico, 351 loggerhead sea turtles have reportedly died on the same coastline.

Its thought that the reason for these mass deaths could be the net and line fishing off the Baja California coast.

The Mexican Centre for Environmental Law and the Centre for Biological Diversity say that these deaths underline the need to ban net and line fishing in the region.

Reports of the dead sea lions first emerged on September 2. They were scattered across a 120km stretch of coast.

California sea lions are a protected species in Mexico although they are not believed to be in danger of going extinct.

The animals are renowned for their intelligence and playfulness and are highly social. They move in packs up and down the Pacific coast, between Canada and the south of Mexico.

Authorities had said that there were no obvious signs of injury from fishing nets or lines. However, tissue samples are being collected in order to understand the cause of death.

Hundreds of loggerhead turtles are dying every year

Loggerhead sea turtles are considered endangered in Mexico. And while officials claim their deaths are not caused by fishing, activists are disputing this. They also feel that authorities are not doing enough to protect the turtles.

There is supposed to currently be a temporary ban on commercial long-line and gill net fishing. Under these regulations, a maximum of 90 loggerhead turtles are allowed to perish.

But that number is far higher, with the 351 dead turtles found this year.

In 2019, 331 deceased loggerhead turtles were found washed up in the region. The year before that number was even worse: 459.

Loggerhead sea turtles usually weigh about 135 kg, but large specimens can reach over 400kg. They are just under one meter in length. They can be found in the Atlantic, Pacific, and Indian Oceans, and also the Mediterranean Sea.

More Bird Die Offs – What Is Happening?

Hundreds of thousands of migratory birds dead in one of the Southwest’s largest bird die-offs on record, U.S.

Hundreds of thousands of migratory birds dead in one of the Southwest's largest bird die-offs on record, U.S.

Mystery ensues across New Mexico as hundreds of thousands of migratory birds have been found dead across the state in one of the Southwest’s largest bird die-offs in recent memory. Scientists are examining the reason behind the alarming event, looking at possible factors such as the wildfires on the West Coast, the cold snap in the Mountain West, or the drought in the Southwest.

“It’s just terrible,” said Professor Martha Desmond from the New Mexico State University, noting that the figures are larger than ever seen before.

“The number is in the six figures. Just by looking at the scope of what we’re seeing, we know this is a very large event, hundreds of thousands and maybe even millions of dead birds, and we’re looking at the higher end of that.”

The mysterious deaths began around August 20, when a large number of dead birds were discovered at the U.S. Army White Sands Missile Range and White Sands National Monument.

Scientists initially believed that it was an isolated incident, but it turned out to be a bigger problem when hundreds more dead birds were seen in other regions across the state, including Doña Ana County, Jemez Pueblo, Roswell, and Socorro.

Residents reported seeing birds behaving unusually prior to their deaths. For instance, birds that are commonly seen in trees and shrubs have been found on the ground chasing bugs. Many birds appeared lethargic and unresponsive while on the ground until they get hit by cars.

Desmond, along with other biologists from White Sands Missile Range, started identifying, cataloging, and analyzing around 300 dead birds to learn more about their condition when they died.

Among the species of dead migratory birds found were warblers, sparrows, bluebirds, blackbirds, the western wood pewee, and flycatchers. Some were also found in Colorado, Texas, and Mexico.

One of the factors being considered by biologists is the wildfires on the West Coast, which may have forced the birds to migrate earlier. “Birds who migrated before they were ready because of the weather might have not had enough fat to survive,” Desmond explained.

“Some birds might have not even had the reserves to start migrating so they died in place.” She added, “We began seeing isolated mortalities in August, so something else has been going on aside the weather events and we don’t know what it is. So that in itself is really troubling.”

Some of the birds will be examined at the US Fish and Wildlife Service Forensics Laboratory in Oregon to identify their exact cause of death, but it would take some time to get the results. Desmond remarked that climate change played a role in mass deaths.

“This is devastating,” she continued, “We lost three billion birds in the U.S. since 1970, and we’ve also seen a tremendous decline in insects, so an event like this is terrifying to these populations and it’s devastating to see.”

Meanwhile, Jenna McCullough and Nicholas Vinciguerra, doctoral ornithology students from the University of New Mexico, surveyed the affected area and gathered a total of 305 birds, including 258 violet-green swallows.

“Many of them have little to no fat, many are underweight, and there’s not a lot of external signs that they have been inhaling a lot of smoke,” said McCullough.

Dr. Andrew Farnsworth, a senior research associate at the Cornell Lab of Ornithology, noted that the deaths started before the sharp temperature drop in New Mexico last week, adding that the die-off amounted to a major event,” in the wider problem of migratory birds being killed by other instances.

“It’s different this year than other years,” he said, also noting that the wildfires could be a potential factor. “We’ve had plenty of hot summers but very few that have had these huge-scale fires combined with heat combined with drought.”

Tristanna Bickford, a spokeswoman for the New Mexico Department of Game and Fish, agreed that it would take time before biologists conclusively identify the reason for the die-off.

Some specimens will also be sent to the National Wildlife Health Center in Wisconsin for examination, where it would take months to diagnose the cause.

“This is definitely not a normal thing,” stated Bickford, urging people to wear gloves if they collect specimens and hand them over to authorities.

Is This Conclusive Evidence Of A Directed Energy Weapon Being Used In California?

At the very least, it’s bizarre and interesting. According to researcher Dutchsinse, he witnessed a clear beam of directed energy in real-time on September 7th. We know these weapons exist, but is this the best evidence yet of their use?

Dutchsinse states:

Is This Conclusive Evidence Of A Directed Energy Weapon Being Used In California?

This is a real life example of something beaming from somewhere very strange (Malheur or above it in space) to another location hundreds of miles away in California, beaming directly into a fire…

High power microwave can show up on IR. So can high power IR lasers. Both could theoretically cause fires.

The first video is not enhanced, but this is followed by a color enhanced version.

Best view of the beam seen in full HD 1080p at 11:34 or so. another good view at 13:20 or so… In a very strange turn of events, upon the upload and premiere of this video on youtube.. almost all shots of the beam are hard to see only on youtube (you can see just fine on twitch for instance). You literally cannot see the beam in the half video here on youtube that was seen live by my audience just fine over on twitch.

Nonetheless you can view pretty well in 1080p HD using a laptop , maybe turn down the lights and look close. The live links are provided for you to see on your own instead of having to watch this video.

DHS Braces For ‘Potential EMP Attack’ As Presidential Election Nears 

The U.S. Department of Homeland Security (DHS) released a new report warning about a “potential” electromagnetic pulse (EMP) attack against the U.S.

DHS’s warning published Thur. (Sept. 2), or about 60 days until the U.S. presidential election on Nov. 3, indicates there are “evolving threats against the American homeland, most recently highlighting efforts to combat an Electromagnetic Pulse attack which could disrupt the electrical grid and potentially damage electronics.”

The department released an EMP status report via the Cybersecurity and Infrastructure Security Agency (CISA) that said the “key actions to address known EMP-related vulnerabilities to critical infrastructure.”

CISA said an EMP attack could “disrupt, degrade, and damage technology” embedded in critical infrastructure systems. Widespread blackouts could be seen if an EMP was to damage the nation’s electrical grid, resulting in additional flare-ups of socio-economic turmoil.

“EMP attacks are part of the emerging threats against our nation and demand a response,” said Senior Official Performing the Duties of the Deputy Secretary Ken Cuccinelli.

“That is why DHS is taking these contingencies very seriously, working diligently to mitigate our risks and equipping our state and local partners with the resources they need to do the same. We’ve made significant progress and look forward to work ahead,” Cuccinelli said.

CISA Director Chris Krebs said top priorities of the agency is to mitigate threats associated with EMPs:

“Over the past year, we have worked with interagency and industry partners to identify the footprint and effects of EMP threats across our National Critical Functions, and are developing sustainable, efficient, and cost-effective approaches to improving the Nation’s resilience to EMPs,” Krebs said.

To combat these emerging threats, President Trump signed an executive order in March 2019, delegating power to the White House for EMP preparedness.

We recently quoted Peter Vincent Pry, ex-chief of staff of the Congressional EMP Commission, who wrote an op-ed that said the virus pandemic from China has “exposed dangerous weaknesses in U.S. planning and preparation for civil defense protection and recovery, and those weaknesses surely have been noticed by our potential enemies: China, Russia, North Korea, Iran, and international terrorists.”

Pry warned that “China has been planning to defeat the U.S. with an EMP and cyber “Pearl Harbor” attack for a quarter-century.”

DHS nor CISA gave any more information on ‘evolving EMP threats’ on the American homeland. There was not mention of whether the threat could be from a solar storm or EMP weapons. However, the EMP status report did mention DHS is currently running EMP pilot tests to assess EMP vulnerability on infrastructure:

“Finally, DHS is partnering with other federal departments and agencies, state, local, tribal, and territorial entities and the private sector to field test a more resilient critical infrastructure. There are a number of field demonstration (or pilot) projects planned and underway by both DHS and DOE to assess EMP vulnerability and then deploy, evaluate, and validate EMP mitigation and protection technologies.

“One such pilot is the San Antonio Electromagnetic Defense Initiative, designed to show how an entire region can become resilient against an EMP. These pilots are multisector, multifunction efforts, seeking to ensure key capabilities continue to function in a post EMP environment and that by maintaining those key functions we can expedite a full recovery. Working with federal interagency partners, DHS will play a major role in ensuring communications systems remain operational and, by ensuring key systems which are protected against EMP, are also protected against other threats such as cyber-attacks.” – EMP status report

One EMP-expert and friend-of-the-site summed up the report perfectly:

“We recognize the threat and we’re working on it and you don’t need to know any more than that, thank you for asking…”

The warning comes just two months before the U.S. presidential election…

“A Pothole in Space”

NASA Keeping Tabs on the Growing Rip in Earth’s Magnetic Field

Paul Seaburn

“Although the South Atlantic Anomaly arises from processes inside Earth, it has effects that reach far beyond Earth’s surface. The region can be hazardous for low-Earth orbit satellites that travel through it. If a satellite is hit by a high-energy proton, it can short-circuit and cause an event called single event upset or SEU. This can cause the satellite’s function to glitch temporarily or can cause permanent damage if a key component is hit. In order to avoid losing instruments or an entire satellite, operators commonly shut down non-essential components as they pass through the SAA.”

The European Space Agency (ESA) weighed in earlier this year about the South Atlantic Anomaly (SAA) – the mysterious dent in Earth’s magnetic field over the South Atlantic that is being weakened to the point of splitting apart by the planet’s molten metal outer core churning around and shifting old tectonic plates on top of each other so that they block the outer core from forming the magnetic field. Now NASA decided it’s time to reveal its concern about the SAA and how it’s affected NASA’s moneymakers – satellites.

In a press release accompanying an explanatory video (watch it here), NASA scientists explain how the SAA is like “a pothole in space,” jarring satellites every time they pass over it, causing electronic glitches, short circuits and other physical damage. And no, they can’t just fly around it because the SAA is far too big and a detour would make the area of missed communications even larger.

“In addition to measuring the SAA’s magnetic field strength, NASA scientists have also studied the particle radiation in the region with the Solar, Anomalous, and Magnetospheric Particle Explorer, or SAMPEX – the first of NASA’s Small Explorer missions, launched in 1992 and providing observations until 2012.”

Even though the rip keeps getting bigger, NASA appears less concerned about what’s directly underneath it on the surface, so it seems to imply that the increased solar radiation is nothing to worry about … yet. It can still affect ships and planes passing through, but the worst part is that the anomaly is “slowly but steadily drifting in a northwesterly direction.” You don’t need Google maps (although you might want to use them while you still can) to figure out that ‘northwest’ is the direction of South and North America. However, the press release still refers to the South Atlantic Anomaly as a “dent” and focuses primarily on “Modeling a safer future for satellites” – where NASA and SpaceX make their money.

Cynical? Yes. The SAA is obviously more than a “pothole in space” to be getting this kind of attention.

Getting Back to Nature

Nature Mysticism: A Postmodern and Age-old Wisdom of the Heart

August 19th, 2020

By Santoshan (Stephen Wollaston)

Guest Writer for Wake Up World

Many early Celtic Christians drew heavily on the Gospel of John for their inspiration … Early Celtic Christians …. (were) seeking to find God’s physical presence in the natural world and the wonders of Nature. Their art, prayers, teachings, poems and writings are full of deep mystical insights into the activities of Nature. For the 14th and 15th century English mystic Julian of Norwich, God was seen in everything – the human body and the body of creation – and she insisted, as the early Celtic tradition had done, that both Nature and grace were one.

Similarly for many Hindu yogis, God and (Nature) are one and the same. The Srimad Bhagavata Purana (11.2.41) states that, “Ether, air, fire, water, earth, planets, all creatures, directions, trees and plants, rivers and seas, they all are organs of God’s body; remembering this, a devotee respects all species”. We can see that when we penetrate the deeper dimensions of Christianity and Yoga, we discover elements of Nature mysticism embedded within them ….

In fact, any experience of deep contact with Nature often helps in the healing process … and leads us to discover wider and more holistic perspectives of existence that inevitably enrich us in profound and life enhancing ways. Doctors now recognise that simply walking in Nature is one of the best exercises for physical health and mental well-being. … Deep within the majority of children and adults there is a natural sense of awe and wonder experienced when they look up at the multitude of stars that can be seen at night or contemplate the rich beauty of Earth and its colossal array of plants, flowers, trees, insects, animals and birds.

At weekends and on holidays our love of Nature often impels us to escape our brick and concrete buildings to find time to rediscover this natural element of spirituality …

Yet because of mass urbanisation and consumerist pressures and through seeing the world full of resources to plunder and exploit, humankind often does not realise that much of what is loved about the natural world will not be around for long unless a dramatic U-turns is made. Interestingly, all spiritual and mystical traditions are about waking up, becoming more aware of life, seeing how all things are interrelated, how skilful and unskilful actions have consequences, and through this understanding to become more responsible for our impact on Earth life. …

Prophets of our age such as Thomas Berry emphasised the importance of ‘the great work’ that lies ahead.  … Berry termed the new era of spirituality needed for our times ‘the Ecozoic era’: an era where humans live in mutually enhancing relationships with Earth and the Earth community – which is different to old ideas of stewardship – as it puts us humans on a more equal footing with the rest of Nature, instead of seeing humans as the peak of Creation.

Berry felt that we had lost our links with Earth because we no longer share myths and stories our early ancestors had that helped them find close bonds with the natural world. Because of this, what is now seen as a New Earth/Universe Story … was recognised by Berry and the evolutionary cosmologist Brian Swimme to be needed for humankind to reconnect with its roots and age-old quests for discovering meaning to life. … Before any God of scripture or God of humans, there has been a God of Nature. …

If we follow on from the paths of wisdom that have gone before and embrace wide visions of spirituality…, we will arrive at a more centred, nourishing and spiritual place. In the midst of such awakenings we tap into the power of authentic being …

Numerous spiritual traditions are about being awake to this potential, and the abilities and possibilities that are available to us in every moment, … This active form of spirituality is intrinsically bound-up with wholeness and compassion. It is bound-up with that which can naturally flow from us as a result of wholesome interconnections with all….

Update – Three Gorges Dam

Three Gorges dam facing most severe floods since it was built, China

by (7 hours ago)

Authorities in China’s Hubei province say the Three Gorges Dam is facing the most severe floods since it was built.

By August 20, the Three Gorges Dam in central China’s Hubei Province is expected to see the most severe round of floods since it was completed in 2003, Chinese authorities said.

According to a forecast by the Changjiang Water Resources Commission of the Ministry of Water Resources, the inbound flow of water is expected to reach more than 74 000 cubic meters per second after continuous heavy rain battered the upper reaches of the Yangtze River.

The Yangtze River, China’s longest waterway, recorded the fifth flood of the year in its upper reaches on Monday, August 17, Xinhua reports.

In addition, Chongqing municipality, which is located along the upper reaches of the Yangtze River, upgraded its flood-control response to Level I on Tuesday, the highest rung in the four-tier emergency response system for floods.

The upcoming flood is expected to hit the city proper of Chongqing through Thursday, according to the municipal water resources authorities.

The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, China.

It’s the world’s largest power station in terms of installed capacity (22 500 MW) since 2012.

In 2018, the dam generated 101.6 terawatt-hours (TWh), breaking its previous record, but was still slightly lower than the Itaipú Dam, which had set the world record in 2016 after producing 103.1 TWh.

Another Look At the Nazca Lines

Posted on by

Summary of The Nazca Great Circle Map Hypothesis

The enormous long lines and figures drawn on the Nazca Plateau represent a map of Earth. In a similar way that a flat Mercator map represents the spherical Earth, the two- dimensional lines of the Nazca map represent three-dimensional circles called great circles. These circles can be imagined as invisible rings that encircle the Earth. Most of the straight lines at Nazca radiate from 5 locations on the plateau. The figures of animals and other shapes, called geoglyphs, are like place names on modern maps indicating specific regions of the Earth. Using the figures one can determine the 5 locations on Earth that are represented by the 5 locations on the plateau, and convert the long straight lines of the map into great circles around the Earth.

Once the lines are converted into great circles, a pattern emerges. Under the path of these great circles—in “alignment” with them—are the Earth’s major volcanoes, impact craters and ancient monuments. Submerged ancient structures may also form part of the pattern, as most that have been found, although few in number, seem to be beneath the paths of the great circles of the Nazca map.

The work is divided into three sections:

Part I: The Nazca Great Circle Map Hypothesis. Explains how to read the Nazca map and convert it into its three- dimensional great circle form.

Part II: The Random Simulation Experiment – A Statistical Analysis of The Nazca Great Circle Map-Plateau. Presents the proof of the hypothesis using the Random Simulation Experiment. The Random Simulation is a computer program which tests the great circles of the map for alignment with the major volcanoes, impact craters and ancient monuments of Earth by comparison with random great circles.

Part III: The Geoglyphic Code. Presents the visual evidence that the Nazca geoglyphs represent topographic and bathymetric contours of certain parts of Earth’s surface, similar to the contour drawing style of common maps.

You can view the entire construct on our Virtual Nazca Earth Map, which uses Google Maps to graphically present the lines as Great Circles. It also shows all the locations that we tested in our simulation experiment.

Below is a short video where we visually explain the key concepts. It may be useful to view this before diving into the Hypothesis. We also have an Introduction page which provides background information on various relevant topics such as the Nazca Plateau itself, the physical nature of the Nazca lines, the work of Dr. Maria Reiche, portolan maps, and more.

Hurricane Update 8/18

The Atlantic Basin Is “About To Come Alive”  

Michael Ventrice, an atmospheric scientist at The Weather Company, tweeted Monday morning, “there’s risk for a hurricane to track towards the Gulf of Mexico in 7-10 days.” 

Readers may recall the 2020 Atlantic hurricane season has been extremely busy, with eleven storms so far, and the risk of two more storms developing later this week.

At the start of the hurricane season, we said: “…this hurricane season could be above average, with 13 to 19 named storms.”

The National Hurricane Center (NHC) published a new five-day tropical weather outlook showing two disturbances developing in the eastern Atlantic.

“NHC is monitoring two disturbances for possible development within the next several days.  A system in the eastern Atlantic has a high chance of development and a system near the Windward Islands has a medium chance of formation,” NHC said.

The next 7-10 days could be a period of heightened activity in the Atlantic and or the Gulf of Mexico. NHC said Disturbance #1 has a 50% chance of developing, and Disturbance #2 has a 70% chance of developing by the end of the week.

Meteorologist James Spann tweeted Monday, “the Atlantic basin is about to come alive.”

Atlantic Current Weakening

Florida Current at its weakest in the past 110 years

New research by the Woods Hole Oceanographic Institution (WHOI) found that a key component of the Gulf Stream– a warm Atlantic ocean current stretching to the tip of Florida– has steadily slowed and is now weaker than at any other point in the past 110 years. The connection between coastal sea level and the strength of near-shore currents was analyzed to trace the evolution of the Florida Current and come up with the conclusion.

“In the ocean, almost everything is connected,” said research author Christopher Piecuch, an assistant scientist in the Physical Oceanography Department at WHOI.

“We can use those connections to look at things in the past or far from shore, giving us a more complete view of the ocean and how it changes across space and time.”

Piecuch specializes in coastal and regional sea-level change, and he used a connection between coastal ocean level and the strength of currents near the shore to track the evolution of the Florida Current.

The Gulf Stream flows north along the South Atlantic Coast of the U.S. and eventually east into the North Atlantic, carrying properties that affect the Earth’s climate such as heat, salt, and momentum.

Because almost constant records of water level date back to more than a century along Florida’s Atlantic Coast, Piecuch was able to use mathematical models and physics to widen the reach of direct measurements of the Gulf Stream.

This led him to his conclusion that the current has weakened steadily and is weaker now than any other time in the last 110 years.

However, one of the biggest uncertainties in climate models is the behavior of currents leading or responding to changes in the world’s climate. One of the most significant of these is the Atlantic Meridional Overturning Circulation (AMOC)– a large system or conveyor belt of ocean currents in the Atlantic that helps balance global climate.

Piecuch’s study agrees with relationships displayed in models between the deeper branches of the AMOC and the Gulf Stream. It verifies other studies suggesting that the deeper branches of AMOC have slowed in the past years. His method also provides the potential to monitor ocean currents like the Gulf Stream from the coast, complementing moored instruments and expensive research vessels.

“If we can monitor something over the horizon by making measurements from shore, then that’s a win for science and potentially for society,” the author said.

Abstract

The Florida Current marks the beginning of the Gulf Stream at Florida Straits, and plays an important role in climate. Nearly continuous measurements of Florida Current transport are available at 27°N since 1982. These data are too short for assessing possible multidecadal or centennial trends. Here I reconstruct Florida Current transport during 1909–2018 using probabilistic methods and principles of ocean physics applied to the available transport data and longer coastal sea-level records. Florida Current transport likely declined steadily during the past century. Transport since 1982 has likely been weaker on average than during 1909–1981. The weakest decadal-mean transport in the last 110 y likely took place in the past two decades. Results corroborate hypotheses that the deep branch of the overturning circulation declined over the recent past, and support relationships observed in climate models between the overturning and surface western boundary current transports at multidecadal and longer timescales.
