Lauterbach warnt vor Hitzewelle, die es nicht gibt

Ganz offen gestanden – ich suchte zuerst den Hinweis darauf, dass es sich um Satire handelt, als ich bei den geschätzten Kollegen von Achgut heute folgenden Vorspann las: „Der Bundesgesundheitsminister hat eindringlich vor einer Mega-Hitzewelle mit Todesgefahr für viele Menschen gewarnt, aber der Deutsche Wetterdienst weiß nichts davon.“

Das kann nicht ernst gemeint sein, war meine erste Reaktion. Doch nach ein paar Sekunden hatte ich mich gefangen. Schließlich ist mir bewusst: Bei Lauterbach – und nicht nur bei ihm – ist heute nichts so absurd, dass es nicht der Realität entsprechen könnte.

Solar differential rotation reproduced with high-resolution simulation

(Published: 13 September 2021)

Here, we show that a high-resolution calculation succeeds in reproducing the solar-like differential rotation. Our calculations indicate that the strong magnetic field generated by a small-scale dynamo has a significant impact on thermal convection. The successful reproduction of the differential rotation, convection and magnetic field achieved in our calculation is an essential step to understanding the cause of the most basic nature of solar activity, specifically, the 11 yr cycle of sunspot activity.

Corruption Of The Peer-Review And Publishing Process: “Follow The Silence”

On that thread, and at the risk of losing my advertising again, scientific integrity has managed to sink even lower since the onset of the pandemic. As noted by Dr. Bret Weintstein in a recent DarkHorse video (embedded below), a new and much anticipated study into the prevalence of myocarditis (inflammation of the heart muscle) following a COVID vaccination has, at the eleventh hour, been refused by the publishers — this is even though the paper passed the peer-review process!

As Dr. Weinstein, an environmental biologist, explains: “This paper had passed peer-review and was headed for publication when the Elsevier Journal, a cardiology journal, replaced the pre-print of the paper with a note saying that it had been removed.”

3 Things Scientists Need to Know About the IPCC

(01.09.2015)

The bottom line is that this is a week of naked political horse trading that goes on behind closed doors. Journalists are not allowed to witness what takes place, which is why we’ve been looking at official IPCC photos here. This is what they permit us to see.

It’s only after the diplomats have haggled over this Summary – paragraph by paragraph – that the final version gets officially released at a press conference.

The world is then told that science has spoken. But what’s just happened has nothing to do with science. Scientific truth is not determined in the dead of night by UN-level negotiations. On what planet would such an approach make scientific sense?

But the bad news doesn’t stop there. There’s actually a step in the IPCC process in which the original, lengthy report gets amended so that it conforms to the politically-negotiated Summary. I am not making this up.

A Unified Model for the Fan Region and the North Polar Spur: A bundle of filaments in the Local Galaxy

We present a simple, unified model that can explain two of the brightest, large-scale, diffuse, polarizedradio features in the sky, the North Polar Spur (NPS) and the Fan Region, along with several otherprominent loops. We suggest that they are long, magnetized, and parallel filamentary structures thatsurround the Local arm and/or Local Bubble, in which the Sun is embedded. We show this modelis consistent with the large number of observational studies on these regions, and is able to resolvean apparent contradiction in the literature that suggests the high latitude portion of the NPS isnearby, while lower latitude portions are more distant. Understanding the contributions of this localemission is critical to developing a complete model of the Galactic magnetic field.

Dunlap Astronomer discovers we may be surrounded by tunnel-like structure

(Oct.14, 2021)

Dr. Jennifer West, Research Associate at the Dunlap Institute for Astronomy and Astrophysics, is making a scientific case that two bright structures that are seen on opposite sides of the sky – previously considered to be separate – are actually connected and are made of rope-like filaments. This connection forms what looks like a tunnel around our solar system.

“If we were to look up in the sky,” explains West, “we would see this tunnel-like structure in just about every direction we looked – that is, if we had eyes that could see radio light.”

Studying the Edge of the Sun’s Magnetic Bubble

(Oct 19, 2021)

The space radiation that comes at us from other stars is called galactic cosmic radiation (GCR). Active areas in the galaxy – like supernovae, black holes, and neutron stars – can strip the electrons from atoms and accelerate the nuclei to almost the speed of light, producing GCR.

On Earth, we have three layers of protection from space radiation. The first is the heliosphere, which helps block GCR from reaching the major planets in the solar system. Additionally, Earth’s magnetic field produces a shield called the magnetosphere, which keeps GCR out away from Earth and low-orbiting satellites like the International Space Station. Finally, the gases of Earth’s atmosphere absorb radiation.

With NASA Data, Researchers Find Standing Waves at Edge of Earth’s Magnetic Bubble

(Oct.6, 2021)

The latest work considers the waves that form across the entire surface of the magnetosphere, using a combination of models and observations from NASA’s THEMIS mission, Time History of Events and Macroscale Interactions during Substorms.

The researchers found when solar wind pulses strike, the waves that form not only race back and forth between Earth’s magnetic poles and the front of the magnetosphere, but also travel against the solar wind. Archer likened these two kinds of movement to crossing a river: A boat can go from one riverbank to the other (traveling towards the poles) and upstream (against the solar wind). At the front of the magnetosphere, these waves appear to stand still.

Interplay Between Magnetic Force and Gravity in Massive Star Formation

(September 26, 2021)

The magnetic field is part of one of the four fundamental forces in nature. It plays a vital role in everyday life, from producing electricity in hydroelectric power plants to diagnosing diseases in medicine. Historically, the Earth’s magnetic field served as a compass for travelers before modern technology was available. Crucially for life, the Earth’s magnetic field acts as a shield protecting us from charged particles emanating from the Sun, which are accelerated by the Sun’s magnetic field. Removing this shield would very likely extinguish life on Earth.

Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 mT). The magnetic-field effect on CO2 solubility is twice as large, from which we surmise that geomagnetic field variations modulate the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic dipole moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

Carbon-14 is useful not only for dating things, but because the interaction of cosmic rays with molecules in the atmosphere produces a lot of it. And when the Earth has a weakened magnetic field, more cosmic rays hit the planet.

Surprise: Solar System „Force Field“ Shrinks Fast

(October 1, 2010)

It’s cold, dusty, and bereft of planets, but the outskirts of our solar system are anything but dull, according to increasing evidence from NASA’s Interstellar Boundary Explorer (IBEX) craft.

As charged particles flow out from the sun, they eventually bump up against interstellar medium—the relatively empty areas between stars. These interactions „inflate“ a protective bubble that shields Earth and the entire solar system from potentially harmful cosmic rays (solar system pictures).

“Our Earth gets bombarded by cosmic rays, galactic cosmic rays all the time,” he says. These rays can subtly affect airplanes that fly near the poles, often on trips between Europe or Asia and the US.

Scientists say that to study other planet’s astrospheres, which is what heliospheres are called when they surround other stars, we must first understand our own.

Earth and Mars: Evolution of Atmospheres and Surface Temperatures

(7. Juli 1972)

Indeed, detailed global climatic models (17) suggest that a relative increase in A of only 2 percent is enough to induce extensive glaciation on Earth, which implies that the present climate is extremely sensitive to albedo. This leaves changes in atmospheric composition as a possible explanation. Major variations in the CO2 abundance will have only minor greenhouse effects because the strongest bands are nearly saturated. A change in the present CO2 abundance by a factor of 2 will produce directly a 2° variation in surface temperature (18). The CO2 abundance is highly controlled by silicate-carbonate equilibria; by buffering with seawater, which contains almost 100 times the atmospheric CO2; and by the respiration and photosynthesis feedback loop (19).

More distant quasars have been found in the past. But the new one is notable because it is “radio-loud” – it is the first time that radio jets have been able to be detected from such a distant object.

Quasars are among the brightest objects in the universe. They are found at the centre of some galaxies nd are powered by supermassive black holes – when the surrounding gas is eaten by the black hole, it throws out energy that travels across the universe and can be studied by scientists.

Earth and Mars: Evolution of Atmospheres and Surface Temperatures

(7. Juli 1972)

Indeed, detailed global climatic models (17) suggest that a relative increase in A of only 2 percent is enough to induce extensive glaciation on Earth, which implies that the present climate is extremely sensitive to albedo. This leaves changes in atmospheric composition as a possible explanation. Major variations in the CO2 abundance will have only minor greenhouse effects because the strongest bands are nearly saturated. A change in the present CO2 abundance by a factor of 2 will produce directly a 2° variation in surface temperature (18). The CO2 abundance is highly controlled by silicate-carbonate equilibria; by buffering with seawater, which contains almost 100 times the atmospheric CO2; and by the respiration and photosynthesis feedback loop (19).

Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 mT). The magnetic-field effect on CO2 solubility is twice as large, from which we surmise that geomagnetic field variations modulate the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic dipole moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

Furthermore, this magnetic field surrounds the entire solar system, creating a giant bubble known as the heliosphere that is filled with electrified gas known as plasma. Disturbances in this plasma can affect the planets, creating aurorae and interfering with the behaviour of technology.

Equatorial solar rotation and its relation to climatic changes

(29. September 1977)

During the years from 1965 to 1976, the magnitude of the solar rotation speed averaged annually showed a good inverse correlation with the annual relative sunspot numbers. It is suggested that this variation of the equatorial solar rotation speed may be responsible for the earth’s present unusual climatic conditions. A similarity concerning the low sunspot activity for 1976 and the year 1643, just before the beginning of the Maunder Minimum (1645-1715) with its very severe climatic conditions, is pointed out. It appears, therefore, likely that the present unusual climatic conditions will remain as long as the solar activity continues to decrease.

It is suggested that long-lasting co-rotating active longitudes on the Sun may be associated with small variations of the solar radiation reaching the Earth. The oscillations have a basic period of about 27 days and are not expected to have amplitudes greater than 0.1%. They result in a time-varying heat input to the Earth’s continents and, since the land exchanges heat with the overlying atmosphere, this oscillatory heating process generates large-scale planetary waves, mainly of the Rossby-Haurwitz type, in the atmosphere.

NASA Researchers Track Slowly Splitting ‚Dent‘ in Earth’s Magnetic Field

Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows these particles to dip closer to the surface than normal. Particle radiation in this region can knock out onboard computers and interfere with the data collection of satellites that pass through it – a key reason why NASA scientists want to track and study the anomaly.

The South Atlantic Anomaly is also of interest to NASA’s Earth scientists who monitor the changes in magnetic field strength there, both for how such changes affect Earth’s atmosphere and as an indicator of what’s happening to Earth’s magnetic fields, deep inside the globe.

Rapid changes in field direction have also attracted significant attention, particularly in the context of polarity reversals18. Historically, the fastest directional changes were attributed to lava flows at Steens Mountain, though these results are now thought to be untenable19. Currently, the fastest directional changes noted are those recorded by sediments in central Italy20, where angular changes in the Virtual Geomagnetic Pole position (P^V) reach values of ∂P^V/∂t∼1∘yr−1. These rates are about a factor of 10 faster than values of ∂P^V/∂t∼0.1∘yr−1 for the modern field, similar to the difference in rates of intensity change between the modern field and spikes.

The temperatures we experience on the ground do not get colder because of this solar cycle. NASA and other climate researchers continue to see a warming trend in the troposphere. These two effects are ongoing but unrelated.

Nitric oxide and carbon dioxide play important roles in cooling the thermosphere.

Zum Venustransit: Leben in Säurewolken?

Andere Astrobiologen haben dagegen noch grundsätzlichere Bedenken. Wenn es die venerischen Luftbazillen wirklich gäbe, so ihr Einwand, hätten sie oder ihre Stoffwechselprodukte in den Meßdaten der Venussonden schon lange auffallen müssen. „Wo Leben existieren kann, neigt es zu Dominanz“, sagt etwa der Nasa-Astrobiologe Chris McKay. „Wenn ich aus meinem Fenster blicke, sehe ich überall Grün – warum, bitte, sind die Venuswolken nicht grün?“

Venus clouds ‚might harbour life‘

(25.05.2004)

„Current theories suggest that Venus and the Earth may have started out alike. There might have been a lot of water on Venus and there might have been a lot of carbon dioxide on Earth,“ Professor Ingersoll explained.

But all that was to change. On Earth, life in the oceans took in carbon dioxide and turned it into limestone. On Venus, 30% closer to the Sun, any oceans boiled away and the water vapour added to the runaway greenhouse effect.

Life in the Clouds of Venus?

(16.09.1967)

WHILE the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether. As was pointed out some years ago, water, carbon dioxide and sunlight—the prerequisites for photosynthesis—are plentiful in the vicinity of the clouds. Since then, good additional evidence has been provided that the clouds are composed of ice crystals at their tops and it seems likely that there are water droplets toward their bottoms. Independent evidence for water vapour also exists5.

Water vapor in the atmosphere of Venus

(December 1972)

Infrared spectra of Venus produced by a Fourier spectrometer flown aboard the NASA CV 990 jet aircraft were analyzed for water-vapor content by comparison with calculated model spectra. The reflecting layer model gave an abundance of 1.6 ± 0.4 μ of precipitable water for the two-way transmission of the Venus atmosphere. The scattering model resulted in a value of 0.25 ± 0.10 μ of water per scattering mean free path.

Detection of phosphine: new aspects of the phosphorus cycle in the hydrosphere

(26.05.1988)

According to our measurements and calculations, about 5g of phosphorus per day was released as phosphine from an Imhoff tank settling 2,000 m3 per day of raw sewage. Under laboratory conditions, it was also demonstrated that phosphine is released by bacterial reduction from a medium containing inorganic phosphorus.

Meteorite study suggests Earth may have always been wet

(27.08.2020)

A new study finds that Earth’s water may have come from materials that were present in the inner solar system at the time the planet formed — instead of far-reaching comets or asteroids delivering such water.

Earth’s water may have been inherited from material similar to enstatite chondrite meteorites

(28.08.2020)

The origin of Earth’s water remains unknown. Enstatite chondrite (EC) meteorites have similar isotopic composition to terrestrial rocks and thus may be representative of the material that formed Earth. ECs are presumed to be devoid of water because they formed in the inner Solar System. Earth’s water is therefore generally attributed to the late addition of a small fraction of hydrated materials, such as carbonaceous chondrite meteorites, which originated in the outer Solar System where water was more abundant. We show that EC meteorites contain sufficient hydrogen to have delivered to Earth at least three times the mass of water in its oceans.

Durch die gestörte Symmetrie ist es möglich, die sogenannte elektrische Polarisation des Kristalls mit einem Magnetfeld zu verändern. Dabei ist nicht nur die Stärke des Magnetfeldes entscheidend, sondern auch dessen Richtung. „Wenn man die Richtung des Magnetfelds ein kleines bisschen dreht, kann die Polarisation völlig umkippen. Das ist eine neue Form des magnetoelektrischen Effekts, die man bisher noch nicht kannte“, erklärte der Physiker.

The 5 best places to explore in the solar system—besides Mars

In studying Pluto, “we can get a sense of what goes on in the Kuiper belt, and how it’s able to produce these geologically active bodies that are so small and distant from the sun but still have enough internal energy to drive these processes,” says Karunatillake. Pluto could be a sign that just because another world is far away from the sun doesn’t mean it’s completely dead.

As with Ceres, however, there just hasn’t been enough time since the last mission to justify greenlighting a new one yet. We may need to wait another decade before NASA or another institution thinks it’s time to launch another spacecraft to Pluto.

NASA Satellite’s Lone View of Betelgeuse Reveals More Strange Behavior

STEREO’s measurements revealed that Betelgeuse is dimming again — an unexpected development so soon after its last dim period. Betelgeuse typically goes through brightness cycles lasting about 420 days, with the previous minimum in February 2020, meaning this dimming is happening unexpectedly early. These observations were reported by the science team via The Astronomer’s Telegram on July 28, 2020. This is an intriguing phenomenon that scientists will study with additional Earth-orbiting and ground-based observatories when Betelgeuse returns to the night sky in late August.

Forbidden Op-Ed: The Sputnik Vaccine as a Lifesaving Global Partnership

The use of two vectors is the unique technology, developed by the Gamaleya Center scientists, which differentiates the Russian vaccine from other adenoviral vector-based vaccines under development around the world. Vaccines based on adenoviral vectors also have clear advantages over other technologies such as mRNA vaccines.

Prospective mRNA vaccines, undergoing clinical trials in the United States and other countries, do not use vectors for delivery and represent an RNA molecule with coronavirus protein code wrapped in a lipid membrane. This technology is promising but its side effects, especially an impact on fertility, have not yet been studied in depth. No mRNA vaccine has yet received regulatory approval in the world.

The Earth’s magnetic field in Jerusalem during the Babylonian destruction: A unique reference for field behavior and an anchor for archaeomagnetic dating

Archaeomagnetism, the application of paleomagnetic methods to archaeological materials, is interdisciplinary not only in its methods but also in its impact. Well-dated archaeological materials are a critical data source for geomagnetic secular variation models [1–6], which are used to explore the dynamic structure of Earth’s core [7, 8], the rates of cosmogenic isotope production in the atmosphere [9–11] and the possible effect of geomagnetism on climate [11–13]. Precise documentation of the ancient field also helps contextualize geomagnetic observations from the modern era, such as the evolution of the South Atlantic Anomaly [14, 15] and the ongoing decline in the field’s intensity [16–18].

Albert Einstein once called the behavior of the magnetic field one of the great mysteries of physics, but understanding and possibly predicting its changes has taken on a new urgency for scientists. The field has lost around 10 percent of its strength since measurements began less than 200 years ago, leading some researchers to question whether we are on the way to a flip in polarity, which would be preceded by a loss of our precious shield against cosmic radiation.

No need to Mind the Gap: Astrophysicists fill in 11 billion years of our universe’s expansion history

This map represents the combined effort of more than 20 years of mapping the Universe using the Sloan Foundation telescope. The cosmic history that has been revealed in this map shows that about six billion years ago, the expansion of the Universe began to accelerate, and has continued to get faster and faster ever since. This accelerated expansion seems to be due to a mysterious invisible component of the Universe called “dark energy,” consistent with Einstein’s General Theory of Relativity but extremely difficult to reconcile with our current understanding of particle physics.

The end of world population growth

There has been enormous concern about the consequences of human population growth for the environment and for social and economic development. But this growth is likely to come to an end in the foreseeable future. Improving on earlier methods of probabilistic forecasting1, here we show that there is around an 85 per cent chance that the world’s population will stop growing before the end of the century. There is a 60 per cent probability that the world’s population will not exceed 10 billion people before 2100, and around a 15 per cent probability that the world’s population at the end of the century will be lower than it is today.
