Two firefighting pilots confirmed dead
In a statement, the General Air Staff Air Force named the two officers as Captain Christos Moulas (34) and his co-pilot, Second Lieutenant Periklis Stefanidis (27).
Leading tributes to the two pilots, President Katerina Sakellaropoulou said: “Our sense of gratitude is immense and our sorrow for their loss profound.”
Study: Sun’s magnetic field is weakening
(Oct 7, 2019)
The research, according to the team, will help monitor and evaluate the influence of solar activities and their implications on the Earth’s climate. The astrophysicists’ team included experts from Ahmedabad’s Physical Research Laboratory (PRL), Japan, and China.
The Shrinking of the Heliosphere Due to Reduced Solar Wind
(2010)
Abstract. The heliosphere is the space within which the solar wind dominates and the solar interplanetary magnetic field prevails. Its boundary is determined by the balance between stellar and solar winds. Owing to the present reduction in the solar wind pressure, one would expect that the stellar wind would push the heliosphere inward leading to its shrinkage. In this paper we calculate the extent of the heliosphere at different solar wind status.
Backward estimation of the extent of the heliosphere since 1890 is done. It is found that the heliosphere oscillated between 75 and 125 AU between 1890 –
2010. Most important is the forecast of the shrinkage and oscillations of the heliosphere and their implications on the earth. The shrinkage of the heliosphere would allow more invasions of cosmic rays to the earth and planets, increased cloud cover and a cooler Earth.
1 Introduction
The heliosphere is the cavity curved by the solar wind into the interstellar medium. Its extension is determined by the equality of the solar wind pressure and the stellar wind pressure. For this reason, we will first study past, present and future status of solar activity and then we will reflect this study into the heliosphere.

No, Antarctic Ice Isn’t Melting Into Oblivion; + Shiveluch Erupts (Again)
If the world’s propagandizing ‘news’ outlets insist on reporting that Antarctica sea ice is melting in oblivion–which NASA reveals it most certainly isn’t–then they need to come up with a new mechanism to support it, because temperatures, clearly, are playing no part.
Death toll rises to at least 55 as freezing temperatures and heavy snow wallop swaths of U.S.
Stretching from the Great Lakes near Canada to the Rio Grande along the Mexican border, the storm has killed at least 55 people as of Monday morning, according to an NBC News tally. The deaths were recorded in 12 states: Colorado, Illinois, Kansas, Kentucky, Michigan, Missouri, Nebraska, New York, Ohio, Oklahoma, Tennessee and Wisconsin.
Cold Records Shattered Across Canada, Driving Energy Usage To All-Time Highs; Extreme Freeze Sweeps U.S.; Blizzards Hit Hawaii; + Wintry Weather Traps 300 Oil Workers On North Sea Rig

As hinted at above, Mauna Loa began erupting on Nov 27 and stopped on Dec 13.
It was the first time it has actively erupted since 1984 (solar minimum of cycle 20) — and is a sign of the times…
Volcanic eruptions are one of the key climatic forcings driving Earth into its next bout of global cooling. They have been shown to increase in both number and explosivity during times of prolonged solar decline, which is thought to be due to an influx of cosmic rays (CRs) penetrating/exciting silica-rich magma. During solar mins the Sun’s magnetic field weakens and the outward pressure of the solar wind decreases, which allows more CRs to enter the inner solar system, including our planet’s atmosphere.
Cold Wave Grips East Asia, Felling All-Time Snowfall Records Across Japan; Historic Snow In Moscow; + Christmas Freeze: Extreme Cold/Snow To Blast North America Over The Holidays
(December 19, 2022)
The COLD TIMES are returning, North America, in line with historically low solar activity.
Death toll from winter storm rises to at least 31
The storm brought hurricane-force winds and created whiteout conditions as it battered the area. A bomb cyclone, which happens when atmospheric pressure drops sharply in a strong storm, developed over the Great Lakes.
The storm has sent temperatures well below freezing in much of the country.
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.
Nations reach climate change agreement in Glasgow but follow-through in doubt
But the deal reached goes further than any before it, in no small part because scientists have made clear that without a significant and sustained effort to lower greenhouse gas emissions, the world is poised to embark upon an era of catastrophic consequences. If the signatories all follow through on their promises and return in 2023 with even stronger emissions targets, it is still possible that mankind could spare itself the worst effects of climate change.
Cop26 summit at serious risk of failure, says Boris Johnson
In a blunt admission after two days of preliminary talks at the G20 meeting of world leaders, the prime minister conceded little progress had been made – and the conference is not on track to achieve a deal that keeps the goal alive. He put the chances of success as “six out of 10”.
“Currently, let’s be in no doubt, we are not going to hit it and we have to be honest with ourselves,” he said. The commitments being made so far were a “drop in the rapidly warming ocean”.
NASA caught “adjusting” Global Temperature Graph — AGAIN
(July 20, 2021)
In what Dr Higgs calls yet another manipulation of the data, in early 2021, NASA discreetly lowered the 2016 global average temperature –previously the highest on record– to make the year 2020 seem like the hottest.
NASA play these ‘games of adjustment’ all the time, and each and every time, without fail, their tweaks support the man-made global warming narrative.
Below are copies of NASA’s 1880-2020 global temperature chart ‘before & after’ their most recent “adjustment”:
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).

Periodic variations of solar radiation – a possible source of solar activity-weather effects
(May 1979)
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.
The effect of the 11-year solar-cycle on the temperature in the upper-stratosphere and mesosphere: Part II numerical simulations and the role of planetary waves
(July 2005)
The numerical simulations presented here suggest a mechanism by which a small change induced by the solar forcing can generate a large atmospheric response.

The Thermosphere Responds to a Weaker Than Normal Solar Cycle
(05.04.2019)
The cooling near solar minimum is natural and specific to the thermosphere. The cooling thermosphere does not affect the troposphere, the layer of the atmosphere closest to Earth’s surface where people live. 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.

Scientists link California droughts, floods to distinctive atmospheric waves
(6.4.2017) Wavenumber-5 consists of five pairs of alternating high- and low-pressure features that encircle the globe about six miles (10 kilometers) above the ground. It is a type of atmospheric phenomenon known as a Rossby wave, a very large-scale planetary wave that can have strong impacts on local weather systems by moving heat and moisture between the tropics and higher latitudes as well as between oceanic and inland areas and by influencing where storms occur.
The slow-moving Rossby waves at times become almost stationary. When they do, the result can be persistent weather patterns that often lead to droughts, floods, and heat waves.
Planetary waves, first found on Earth, are discovered on Sun
(27.3.2017) for a brief period, from 2011 to 2014, scientists had the unprecedented opportunity to see the Sun‘s entire atmosphere at once. During that time, observations from NASA‘s Solar Dynamics Observatory (SDO), which sits between the Sun and Earth, were supplemented by measurements from NASA‘s Solar TErrestrial RElations Observatory (STEREO) mission, which included two spacecraft orbiting the Sun. Collectively, the three observatories provided a 360-degree view of the Sun until contact was lost with one of the STEREO spacecraft in 2014. McIntosh and his co-authors mined the data collected during the window of full solar coverage to see if the large-scale wave patterns might emerge.
„By combining the data from all three satellites we can see the entire Sun, and that‘s important for studies like this because you want the measurements to all be at the same time,“ said Dean Pesnell, SDO project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. „They’re pushing the boundary of how we use solar data to understand the interior of the Sun and where the magnetic field of the Sun comes from.“
Study: Hole in ionosphere is caused by sudden stratospheric warming
(6.8.2018) Geospace research has long established that certain changes in the atmosphere are caused by the sun’s radiation, through mechanisms including solar wind, geomagnetic storms, and solar flares. (…)
One of the more scientifically interesting large-scale atmospheric events is called a sudden stratospheric warming (SSW), in which enormous waves in the troposphere — the lowermost layer of the atmosphere in which we live — propagate upward into the stratosphere. These planetary waves are generated by air moving over geological structures such as large mountain ranges; once in the stratosphere, they interact with the polar jet streams.
A Mystery in the Mesosphere
(15.8.2018) Harvey and her colleagues are still working to understand how the extra water got up there. One possibility involves planetary wave activity in the southern hemisphere which can, ironically, boost the upwelling of water vapor tens of thousands of miles away in the north. The phenomenon could also be linked to solar minimum, now underway. It is notable that the coldest and wettest years in the mesosphere prior to 2018 were 2008-2009–the previous minimum of the 11-year solar cycle.
New study explains Antarctica’s coldest temperatures
(25.6.2018) That preliminary study has been revised with new data showing that the coldest sites actually reach -98 degrees Celsius (-144 degrees Fahrenheit). The temperatures are observed during the southern polar night, mostly during July and August.
When the researchers first announced they had found the coldest temperatures on Earth five years ago, they determined that persistent clear skies and light winds are required for temperatures to dip this low. But the new study adds a twist to the story: Not only are clear skies necessary, but the air must also be extremely dry, because water vapor blocks the loss of heat from the snow surface.
Coldest temperature ever recorded makes Earth „almost like another planet“
Nearly 15 degrees colder than the previous record-breaking coldest temperature, which was -128 degrees in 1983 near the South Pole, the temperature in Antarctica dropped to -144 degrees Fahrenheit.
Temperatures this low make Antarctica „almost like another planet,“ says lead researcher Ted Scambos at the National Snow and Ice Data Center in Boulder, Colorado, quoted in Forbes.
Taking just a few breaths of air this cold would kill you.
Watching the Sun for Space Weather
(10.8.2018) “Space weather occasionally occurs in tandem with extreme terrestrial weather,” according to scientists from NCEI, Cooperative Institute for Research in Environmental Sciences (CIRES), and other institutions in an open access Space Weather journal article. “When it does, the struggle to mitigate the impacts to life and property can be dramatically intensified. This one-two punch landed on the socioeconomically and technologically diverse communities of the Caribbean islands during the September 2017 hurricane season.”
