Shedding New Light on the Sun

parker-probe

This first data from Parker reveals our star, the Sun, in new and surprising ways.

On Dec. 4, 2019, four new papers in the journal Nature describe what scientists have learned from this unprecedented exploration of our star — and what they look forward to learning next.

These discoveries uncover new data about the behavior of the material and particles that dash away from the Sun, bringing scientists closer to answering crucial inquiries about the physics of our star. Moreover, the information Parker has uncovered about how the Sun constantly ejects material and energy will help scientists re-write the models we use to understand and predict the space weather around our planet and understand the process by which stars are created and evolve.

Scientists Predict New Solar Cycle About to Begin

(MSN) The latest 11-year cycle of the sun is almost over and scientists have just released predictions for the next one.

Based on the number of sunspots that formed, scientists considered the last solar cycle, No. 24, “weak.” They predict that the upcoming cycle, No. 25, will be a little more intense but still in the weak category.

This consensus forecast was made public at the annual Space Weather Workshop last week, hosted by the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.

The Sun’s Role in Climate Change

Dr. Nir Shaviv spoke at a Friends of Science event on June 2, 2015, on Solar Forcing. Dr. Shaviv explained and demonstrated that the sun is an important climate driver but it is missing from the standard climate analyses. As a consequence, the standard (i.e. IPCC) models have a much higher climate sensitivity than the real Earth has, such that future climate response to anthropogenic forcing will be “much more benign” than what alarmists claim.

Everything That Happens on Earth Happens in Cycles

It’s a cycle, it’s a cycle, it’s a cycle says Peter Temple who warns we are entering a cooling phase. “[J]ust when we need more energy and warmth, we have politicians trying to tax it out of existence.”

That Time a Bunch of Underwater Mines Exploded and the Sun Was the Only Suspect

Explosives going off without warning is bad news for… well, for everybody. So imagine the U.S. military’s alarm when, on August 4, 1972, it witnessed about two dozen or so spontaneous explosions in the waters off Hon La in North Vietnam. America’s Operation Pocket Money had dropped underwater mines there many weeks before to deter trade ships from venturing to North Vietnam ports. But the mines were only supposed to detonate when ships were around, and Americans surveilling the water from overhead were only seeing clear blue when the bombs went off.

Initially, the explosions were inexplicable. What could have possibly set the mines off? Big marine animals? Equipment malfunctions? Were the North Vietnamese using a secret strategy to blow up the mines remotely?

Over four-and-a-half decades later, we now know the culprit was the sun. According to findings recently published in the journal Space Weather, a powerful solar storm likely triggered the mines’ magnetic sensors and caused them to explode.

“It was a storm of magnificent proportions,” says Delores Knipp, a space weather researcher at the University of Colorado, Boulder and the lead author of the new paper. “It was a big story back in the day, and continues to be a big story.” The storm occurred in between Apollo missions 16 and 17, but it’s generally accepted that the radiation dose would have incapacitated (if not outright killed) astronauts traveling to and from the moon. In addition, other studies on the solar storm found the resulting geomagnetic current created many different power fluctuations in North America. “It’s been a storm that has been known for different effects in different communities.”

The article concludes:

But Knipp says a general estimation, based on current knowledge, is that these sorts of solar storms hit Earth about once every 70 years — “often enough that we need to be thinking about what types of technologies are subject to harm in these kinds of environments.” The question isn’t really if a storm powerful enough to knock out the power grid and wreck our technological equipment will hit us — but when it will happen, and whether we’ll be ready in time to prepare and safeguard our infrastructure.

I follow space weather on YouTube daily on the Suspicious Observer channel and weekly on space physicist Tamitha Skov’s channel. We should all pay close attention to our unstable star.

Scientists: Climate Records ‘Correlate Well’ With Solar Modulation…A Grand Solar Minimum Expected By 2030

International and NASA solar scientists find their Total Solar Irradiance reconstruction extending to 1700 can “correlate well” with Earth’s global temperature records, including a positive net TSI trend during 1986-2008. A new Grand Solar Minimum is expected to commence during the 2030s.

Grand Solar Minimums Marked by Violent Volcanic Activity

Re-blogged from Ice Age Now

J.H. Walker

Under normal orbital rules I would disagree with a descent in a glaciation period this century and possibly several hundred years without a major geological-driver. But this time it could come from man’s own hubris that he is the master of the universe and his attempts at geoengineering cooling in the midst of a known and predicted Grand Solar Minimum (GSM) cooling period.

The problem with GSM isn’t the reduced energy radiating the earth, but the variation in atmospheric circulation and cooling which is variable, unpredictable, and drives warmist liars silly because it’s so inconvenient.

The real problem with GSMs is the angular momentum changes of the largest mass object in the solar system – the Sun -as it attempts to stay within the gravitation laws of the Solar System Gravity well and orbit the moving Solar System BarryCentre. Some orbits changes are so abrupt they perform zero crossings of the BarryCentre itself.

Not only does this have profound implications for the moderation of the Sun’s energy output, it also has profound implications for the smaller rocky inner planets such as Venus and Earth by simulating volcanic – and in Earth’s case – tectonic activity as well.

The Holocene is segmented by abrupt sequences of cooling following geological events such as the Younger Dryas, the 8.5K event, and massive volcanic eruption either during, or lagging a GSM periods.

This modern GSM has increased levels of volcanism either on the rift zones (underwater volcanoes) or from the various volcanic hot spots, and those time-line incidences are increasing with a shortening time span between them.

The Late Antique Little Ice Age (LALIA) experienced 3 massive T6/T7 eruptions. Each named Grand Solar Minimum since has been marked with similar violent eruptive periods. Dalton, the last GSM, was marked by Tambora.

I fear this Modern GSM will be no different.

This graphic was not part of the original post, however it shows major volcano eruptions during and after the LIA.

Heliosphere Protects Earth From More Than 70% of Cosmic Rays.

If cosmic rays influence the formation of low clouds this is an important finding. During a quiet Sun, the heliosphere shrinks, providing less cosmic ray protection and more clouds. During grand minimum the quiet period lasts for more than a decade, allowing the oceans to cool. Your thoughts on this new finding?

NASA post:

One year ago, on Nov. 5, 2018, NASA’s Voyager 2 became only the second spacecraft in history to leave the heliosphere – the protective bubble of particles and magnetic fields created by our Sun. At a distance of about 11 billion miles (18 billion kilometers) from Earth – well beyond the orbit of Pluto – Voyager 2 had entered interstellar space, or the region between stars. Today, five new research papers in the journal Nature Astronomy describe what scientists observed during and since Voyager 2’s historic crossing.

Each paper details the findings from one of Voyager 2’s five operating science instruments: a magnetic field sensor, two instruments to detect energetic particles in different energy ranges and two instruments for studying plasma (a gas composed of charged particles). Taken together, the findings help paint a picture of this cosmic shoreline, where the environment created by our Sun ends and the vast ocean of interstellar space begins.

The Sun’s heliosphere is like a ship sailing through interstellar space. Both the heliosphere and interstellar space are filled with plasma, a gas that has had some of its atoms stripped of their electrons. The plasma inside the heliosphere is hot and sparse, while the plasma in interstellar space is colder and denser. The space between stars also contains cosmic rays, or particles accelerated by exploding stars. Voyager 1 discovered that the heliosphere protects Earth and the other planets from more than 70% of that radiation.

When Voyager 2 exited the heliosphere last year, scientists announced that its two energetic particle detectors noticed dramatic changes: The rate of heliospheric particles detected by the instruments plummeted, while the rate of cosmic rays (which typically have higher energies than the heliospheric particles) increased dramatically and remained high. The changes confirmed that the probe had entered a new region of space.

Before Voyager 1 reached the edge of the heliosphere in 2012, scientists didn’t know exactly how far this boundary was from the Sun. The two probes exited the heliosphere at different locations and also at different times in the constantly repeating, approximately 11-year solar cycle, over the course of which the Sun goes through a period of high and low activity. Scientists expected that the edge of the heliosphere, called the heliopause, can move as the Sun’s activity changes, sort of like a lung expanding and contracting with breath. This was consistent with the fact that the two probes encountered the heliopause at different distances from the Sun.

Cold October (and now November) in perspective

Reblogged from Icecap.us

See references to Maunder and Dalton Minimums.

By Joseph D’Aleo, CCM

Starting in January 2019, unusual and at times record cold has been locked in over the north central states.

Though there was heat in late summer in the southeast and eastern Gulf to the Mid-Atlantic, the cold held in the north central. After a very cold spring with late snows, which significantly delayed or prevented grain planting, a cool summer followed and gave way to a very early cold shot in late September that brought early deep freezes and even record snows in the north central leading to significant crop losses.

There have been 90 all-time record lows versus just 44 all-time record highs this year. That included the all time state record low of -38F in Mount Carroll in Illinois on January 31st.

The cold central deepened in October and pushed to the east bringing very early snow into the Midwest. October saw 3680 record daily lows, 32 all time record lows for the month and no all time record monthly highs (NOAA NCEI).

image

After bringing heavy snows to the Rockies and high plains the cold rolled south with temperatures 30 to 50 degrees below normal.

image

Temperatures dropped to a record of -35F at Logan County Sink in Utah and -46F in Peter’s sink, record coldest for the U.S. for the month of October.

The temperatures the first 9 months have tracked the last 120 years well with multidecadal cycles in the ocean.

image

The cold also follows the solar activity. We are currently in a century or more quiet sun.  In the period in and following the last 11 year cycle low (2007-2011), we had brutal cold and snow here in the U.S. and Europe.

December in 2010, the Central England Temperature (longest continuous record going back to 1659), was the second coldest December.  Snow, which was forecast to be a thing of the past, instead buried the UK for long periods reminiscent of the Dalton solar Minimum of the early 1800s as evidenced by Dicken’s novels.

image

In the US, record cold and snow in the Snowmageddon Mid-Atlantic winter of 2009/10, was eclipsed with the record winters of 2013/14 and 2014/15. Which brought the coldest and snowiest winter and modern day peaks of Great Lake ice.

The snow in the hemisphere is increasing very rapidly and is above normal, which should expand and enhance the cold. Note how the fall record for snow extent was at record levels last fall.

Given the projection by Russian scientists and many in the west including some at NASA, we could be heading into a deep and long solar minimum like the Maunder Minimum with a major cooling. Whether it is a several decade Dalton like period or a Maunder, this is no time to abandon cheap, available energy.

Even in the warmer interlude we have enjoyed, cold weather kills 20 times as many people as hot weather, according to an international study analyzing over 74 million deaths in 384 locations across 13 countries.
