If a smart guy on youtube can explain these alien videos why can’t the Department of Defence??

With the US Defence Force about to release “something” on UFO’s, these very engaging videos from Mick West are persuasive and apropos. But if smart guys with trigonometry and metadata can explain how these aliens are mysterious camera artefacts — surely the Pentagon can too?

Why then are they called “unexplained” and why are they being released as teasers for “the big news?” Did the DoD forget parallax and gymbal corrections?

Apparently 120 incidents will be reviewed in June. Former intelligence director John Ratcliffe has hinted the report will be a big deal. Let’s hope they saved the best stuff. I’m looking forward to a good tantalizing mystery.

Michael Shermer (of Skeptic.com infamy) wrote this all up in a long feature on Quillette:

Understanding the Unidentified

The “Go Fast” video purportedly shows an object with no heat source (and therefore propelled by some unconventional engine) that appears to move impossibly fast just above the surface of the ocean. West then conducted what he describes as “10th grade trigonometry” (based on the numbers provided in the video image itself) to show that, in fact, the object was well above the ocean surface at around 13,000 feet and was probably […]

Did a short sharp Geomagnetic storm contribute to the Callide Coal plant explosion?

Ben Davidson speaks from Spaceweathernews.com and claims that there was a short sharp geomagnetic storm over the East Coast of Australia around the time the Queensland Callide Power plant exploded.

The CME that flew past Earth didn’t do much around the world, causing a small 1% deviation in magnetometers. But there was a burst of activity in the Southern Hemisphere that appears to have hit the east coast of Australia. Magnetometers there saw a 300 – 500% change* between noon and 3pm on the same day as the Callide Coal Power Plant blew up. The explosion happened at 1.44pm and the 275 kV transmission lines tripped at 2:06pm.

*(UPDATE: There is some contention in comments about the Australian DST figures — we’re they really that high or unusual? I’ll update the post when I can confirm it either way).

We don’t know if this tipped something over the edge at Callide, but the timing is highly coincidental. If Earth’s magnetic field is weakening it would seem urgent, to say the least, to understand the risks these spaceweather events pose to our critical infrastructure.

Perhaps an engineer who knows the design of (hydrogen cooled) supercritical coal reactors might be able […]

Ominous space-weather: A mild Solar CME caused a bigger geomagnetic storm on Earth than anyone expected

This week a mild Coronal Mass Ejection off the sun blasted past Earth. It was only a mild CME with solar winds at 500km per second, which is a medium kind of speed. The experts were all predicting a G1 class Geomagnetic storm, and were a bit astonished when we got much bigger G3 storm instead. (NOAA’s G scale runs from G1 up to G5).

This occurred near the minimum weak point of the solar cycle, and we’re going to get much bigger blasts as Cycle 25 ramps up. But if mild CMEs can rattle the Earth’s magnetic field this much, things might get much more exciting when moderate or strong CME’s shake the cage. Satellites and networks could be in trouble. “Grid’s Away”…

Is Earths magnetic field weaker or more vulnerable than we thought? How could we miss that?

As Cap Allon of Electroverse said:

“Nobody saw the KP Index hitting 7.

…when I say nobody, I mean nobody predicted this: not NASA, NOAA, ESA or IPS in Australia.”

It was not dense, and the filament released was hardly cause for concern.

“There is absolutely nothing in the history of […]

Signs of life on Venus?

All around the world are dawning headlines wondering if we have founds signs of life on Venus.

Despite the hunt for life on star systems that are lightyears from Earth, it turns out there may be something on the Planet-next-door. “May” being the operative word. A team found phosphine in the atmosphere of Venus and can’t think of any other way it could have got there. Phosphine is considered to be a biomarker. And microbes on Earth would have no trouble making it, though none of them could easily survive on Venus where the atmosphere clouds and rain are nearly pure hot sulphuric acid.*

Scientists find gas linked to life in atmosphere of Venus

Ian Sample, The Guardian

Sara Seager, a planetary scientist on the study at MIT in the US, called the finding “mind-boggling”. She hypothesises a lifecycle for Venusian microbes that rain down, dry out and are swept back up to more temperate altitudes by currents in the atmosphere.

For 2bn years, Venus was temperate and harboured an ocean. But today, a dense carbon dioxide atmosphere blankets a near-waterless surface where temperatures top 450C. The clouds in the sky are hardly inviting, […]

Apollo 11: The inside story of the glorious technical mastery, the risks, the leap

For those who want to immerse themselves in the engineering masterpiece of the Apollo 11 mission, Burt Rutan recommends this documentary series. A whole fascinating hour each. Burt Rutan is an aerospace engineer who has designed 46 aircraft, received six honorary doctoral degrees and hundreds of awards. If these documentaries can keep him interested …

Hail the brilliant technical minds that triumphed and the brave men who got there.

Only 12 men have walked on the moon and three out of four still alive are skeptics. Buzz Aldrin is an outspoken skeptic, as are other astronauts Harrison Schmidt, and Charles Duke. So is Australian born Phil Chapman (support crew, Apollo 14) and Walter Cunningham (Apollo 7). Burt Rutan too, of course.

Remember a time when NASA could achieve great things…

Part I: We choose to go to the moon: Hosted by Bill Whittle

Part II: The clock is running … ….

Burt Rutan says Part 3 and 4 are on the way.

Rutan warns that Google or Youtube searches may not find the series. Apparently Bill Whittle is too politically incorrect for them. At this point the Google search works with […]

Cosmic rays seeded clouds during the last geomagnetic reversal

That’s not in the models

The cosmic ray theory, Henrik Svensmark, (Click to enlarge)

What if our clouds are partly driven by a rain of cosmic radiation from far flung exploding stars… What if the warming on Earth had more to do with magnetic fields than with CO2? h/t GWPF

The Grand Mal test of Henrik Svensmark’s cosmic ray theory was 780,000 years ago when the poles on Earth flipped. For 5,000 wild years our magnetic shield was down to about a quarter of its normal strength. That would have allowed more cosmic rays to come streaking through the atmosphere down to the lowest part, crashing into molecules and generally busting things up in the air. Those ionised particles then seed clouds — in theory, which make an umbrella shade for the planet, keeping things cooler, and reflecting all that solar heat back into space. But how do we measure clouds that disappeared three quarters of a million years ago?

A team at Kobe University studied the patterns of monsoons in East Asia during the reversal. They argue that the extra low clouds would cause the winter monsoons to become stronger, so they looked closely at layers of dust […]

Landmark: First photo of a black hole (and Einstein was right)

A brief break in transmission now for the first photograph of a black hole, looking pretty much exactly as anyone would expect it to. The photons caught in this image traveled for hundreds of years at the speed of light. Lots of “hundreds” — burning through space for some 55 million years.

The numbers melt neurons: The supermassive black hole called M87 is 6.5 billion times bigger than our Sun. It’s bigger than the orbit of Neptune (which is circling 30 times further out from the Sun than we are). This star is 10 billion kilometers across.

Geoffrey Crew, a research scientist at Haystack Observatory commented that “With the M87 black hole being so massive, an orbiting planet would go around it within a week and be traveling at close to the speed of light.”

The black heart of Messier 87, or M87, a galaxy within the Virgo galaxy cluster, 55 million light years from Earth.

It takes a telescope roughly as big as The Earth to catch an image 20 micro-arcseconds across. Eight radio telescopes were combined across four continents and lined up on a few special days when they all had clear weather together. Each telescope took […]

NASA hides page saying the Sun was the primary climate driver, and clouds and particles are more important than greenhouse gases

ZeroHedge asks: What the hell are NASA Hiding?

The NASA site used to have a page titled “What are the primary forcings of the Earth system?“. In 2010 this page said that the Sun is the major driver of Earth’s climate, that it controls all the major aspects, and we may be on the cusp of an ice age. Furthermore NASA Science said things like clouds, albedo and aerosol behaviour can have more powerful cooling effects that outdo the warming effect of CO2.

Today that page says Share the science and stay connected, and “Access Denied”.

https://science.nasa.gov/earth-science/big-questions/what-are-the-primary-causes-of-the-earth-system-variability/

 

Whatever you do, don’t tell the world that NASA says the Sun is more important than CO2.

The Wayback Machine captured the same NASA “Primary Climate Forcings” link in 2010.

Here’s the text from the original page (my bolding).

NASA 2010: What are the primary forcings of the Earth system?

The Sun is the primary forcing of Earth’s climate system. Sunlight warms our world. Sunlight drives atmospheric and oceanic circulation patterns. Sunlight powers the process of photosynthesis that plants need to grow. Sunlight causes convection which carries warmth and water vapor up into […]

Solar cycles to blame for jellyfish plagues (not coal fired plants)

Image Erin Silversmith

Three amazing things in this story. One that solar cycles might influence the oceans to such an extent that jellyfish plagues are cycling in tune with the sun. Second is that the sun might control food for jellyfish on Earth somehow but have no effect on clouds, temperature or our climate (join the dots that expert climate models don’t). Third is that (briefly) there was actual scientific debate published on the ABC (even if only a few Australians were exposed to it). No one called anyone names, and both sides got to speak (albeit on different channels). Put it in your diary.

A couple of weeks ago on the ABC jellyfish were booming and it was because of climate change:

Jellyfish are causing mayhem as pollution, climate change see numbers boom

RN By Hong Jiang and Sasha Fegan for Late Night Live

…the brainless, spineless, eyeless, bloodless creatures are booming in numbers — and causing mayhem around the world.

Some scientists think jellyfish numbers are increasing as the climate changes — the creatures reproduce well in warmer waters.

Last year, Nick Kilvert of the ABC saw it as a […]

The Sahara may flip from desert to grass every 20,000 years. Blame The Sun.

MIT researchers think they have solved a bit of a mystery regarding Sahara dust, but if they’re right it means the Sahara Desert has already come and gone 3 – 5 times since humans walked the Earth. The Sahara is the largest desert on Earth, and this would be the largest and longest drought “ever” on the planet (as far as we know).

UPDATED: Commenter Javier points out these drying cycles were known years ago. (See below)

This would rather redefine the whole idea of “climate change” — 3.5 million square miles of Green Sahara turns into Dust-bowl Sahara — and it’s all thanks to sunlight. The drought doesn’t just last 7 years, but more like 7,000. And it’s happening over 9 million square kilometers, an area larger than Australia. The major climate models leaned towards the monsoonal cycle, rather than the longer ice age one. So this theory may have resolved one of the 495 contradictions in climate models. Or not. But the bigger message here is that the sun causes climate change and on a massive scale.
