Overview

The sun continues to be very quiet and it has been without sunspots this year 62% of the time as we approach what is likely to be one of the deepest solar minimums in a long, long time. In fact, all indications are that the upcoming solar minimum may be even quieter than the last one which was the deepest in nearly a century. In addition, there are now forecasts that the next solar cycle, #25, will be the weakest in more than 200 years. The current solar cycle, #24, has been the weakest with the fewest sunspots since solar cycle 14 peaked in February 1906. Solar cycle 24 continues a recent trend of weakening solar cycles which began with solar cycle 21 that peaked around 1980 and if the latest forecasts are correct, that trend will continue for at least another decade or so.

When will people realize that. . .

  1. The modern short pulse of beneficial Global warming stopped 20 years ago and recent global temperatures are now stable or declining.
  2. The last millennium 1000 – 2000 AD was the coldest of our current Holocene interglacial and the world has already been cooling quite rapidly for the last 3000 years.
  3. At 11,000 years our Holocene interglacial, responsible for all man-kind’s advances, is reaching its end.
  4. The weather gets worse in colder times.
  5. The world will very soon (in geological time), revert to a true glaciation, again resulting in mile high ice sheets over New York.

Our current beneficial, warm Holocene interglacial has been the enabler of mankind’s civilization for the last 10,000 years.

The congenial climate of the Holocene epoch spans from mankind’s earliest farming to the scientific and technological advances of the last 100 years.

However all the Northern Hemisphere Ice Core records  from Greenland show:

  • the last millennium 1000AD – 2000AD has been the coldest millennium of the entire Holocene interglacial.
  • each of the notable high points in the Holocene temperature record, (Holocene Climate Optimum – Minoan – Roman – Medieval – Modern), have been progressively colder than the previous high point.
  • for its first 7-8000 years the early Holocene, including its high point “climate optimum”, had virtually flat temperatures, an average drop of only ~0.007 °C per millennium.
  • but the more recent Holocene, since a “tipping point” at ~1000BC, has seen a temperature diminution at more than 20 times that earlier rate at about 0.14 °C per millennium.
  • the Holocene interglacial is already 10 – 11,000 years old and judging from the length of previous interglacials the Holocene epoch should be drawing to its close: in this century, the next century or this millennium.
  • the beneficial warming at the end of the 20th century to the Modern high point has been transmuted into the “Great Man-made Global Warming Alarm”.
  • eventually, this late 20th-century temperature blip will come to be seen as just noise in the system in the longer term progress of comparatively rapid cooling over the last 3000+ years.
  • other published Greenland Ice Core records as well as GISP2, (NGRIP1, GRIP) corroborate this finding. They also exhibit the same pattern of a prolonged relatively stable early Holocene period followed by a subsequent much more rapid decline in the more recent (3000 years) past.

When considering the scale of temperature changes that alarmists anticipate because of Man-made Global Warming and their view of the disastrous effects of additional Man-made Carbon Dioxide emissions in this century, it is useful to look at climate change from a longer term, century by century and even on a millennial perspective.

The much vaunted and much feared “fatal” tipping point of +2°C would only bring Global temperatures close to the level of the very congenial climate of “the Roman warm period”.

If it were possible to reach the “horrendous” level of +4°C postulated by Warmists, that extreme level of warming would still only bring temperatures to about the level of the previous Eemian maximum, a warm and abundant epoch when hippopotami thrived in the Rhine delta.

Grand Solar Minimum at work – Colorado snowpack more than eight times normal in places

And still rising !!!

After a historically snowy spring, Colorado’s snowpack currently stands at 473% of normal (almost 5 times normal), with highs peaking at 846% (more than 8 times normal!) in the San Juan Mountains, according to the Natural Resources Conservation Service.

Gee and we thought the Sierra at 200% was special.  The melt, which is a month late should fill Boulder Dam.

The Sun Follows The Rhythm Of The Planets

One of the big questions in solar physics is why the Sun’s activity follows a regular cycle of 11 years. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an independent German research institute, now present new findings, indicating that the tidal forces of Venus, Earth and Jupiter influence the solar magnetic field, thus governing the solar cycle.

In principle, it is not unusual for the magnetic activity of a star like the Sun to undergo cyclic oscillation. And yet past models have been unable to adequately explain the very regular cycle of the sun. The HZDR research team has now succeeded in demonstrating that the planetary tidal forces on the Sun act like an outer clock, and are the decisive factor behind its steady rhythm. To accomplish this result, the scientists systematically compared historical observations of solar activity from the last thousand years with planetary constellations, statistically proving that the two phenomena are linked.

“There is an astonishingly high level of concordance: what we see is complete parallelism with the planets over the course of 90 cycles,” enthused Frank Stefani, lead author of the study. “Everything points to a clocked process.”

Supernovae-Induced Lightning May Have Encouraged Humanity’s Ancestors To Walk Upright

Editorial Question: What else could these high energy cosmic rays have caused? Thoughts?

A bombardment of cosmic rays from ancient supernovae may have triggered a series of events that encouraged early human ancestors to walk upright, according to a new study published in the Journal of Geology. The scientists behind the research believe that the cosmic explosion could have helped trigger a shift in Earth’s environment that forced humanity’s fore bearers to adapt.

Supernovae are some of the most dramatic and energetic events known to take place in the visible universe. They can occur either when a white dwarf strips too much matter from a nearby companion star, causing it to become unstable, or when a stellar body many times the mass of our Sun runs out of material to fuel the nuclear fusion process raging in its core.

The end result of both scenarios is a violent explosion that seeds the surrounding environment with vast amounts of stellar material, and bombards worlds hundreds of light-years away with cosmic rays.

There is evidence to suggest that Earth’s atmosphere has been interacting with cosmic energy thrown out by a series of supernovae explosions for the last 8 million years. The authors of a recently published study assert that, at the peak of the bombardment, roughly 2.6 million years ago, the radiation was partially responsible for reshaping the environment of northeast Africa, where humanity’s ancestors where developing.

“We contend it would increase the ionization of the lower atmosphere by 50-fold,” said Melott, lead author of the study. Usually, you don’t get lower-atmosphere ionization because cosmic rays don’t penetrate that far, but the more energetic ones from supernovae come right down to the surface — so there would be a lot of electrons being knocked out of the atmosphere.”

On the Edge of Nowhere

By Russ Steele

It feels like being on the edge of nowhere with no internet connection at our campsite. When we made reservations last year one the things we checked was WiFi access at our chosen campsite. Now that we are there-there is no WiFi, we have to walk about 200 feet to get connected.

According to the Camp Host, a winter lighting storm struck the antenna destroying the antenna and feed cable, the router escaping damage. The only WiFi source is a router with no external antenna.

With limited access, comment moderation may be slow but will try to make contact once a day to check the comments, posting will be as time permits, as we are vacationing with friends.

The Little Ice Age: What Happened Around the World

Between 1300 and 1850, the Earth experienced a Little Ice Age whose cause to this day is not known.

A blog post at Interesting Engineering has more details including the consequences and some paintings from the period. The causes listed are interesting:

Causes

The causes of the LIA are still not known, while potential candidates are reduced solar output, changes in atmospheric circulation, and volcanism.

Low sunspot activity is associated with lower solar output, and two periods of unusually low sunspot activity occurred during the Little Ice Age: the Spörer Minimum (1450–1540) and the Maunder Minimum (1645–1715), which is named for astronomer E.W. Maunder who discovered the absence of sunspots during that period. Both of these coincide with the coldest years of the LIA in parts of Europe.

Another possible candidate is a reversal of the North Atlantic Oscillation (NAO). This is a large-scale atmospheric-circulation pattern over the North Atlantic and adjacent areas. During its “positive” phase, the track of North Atlantic storms is centered over the British Isles and Northern Europe. During its “negative” phase, cold Arctic air from Russia moves over northern Europe.

A final candidate is volcanic eruptions which propel gases and ash into the stratosphere, where they reflect incoming sunlight. In 1783, Iceland’s Laki volcano erupted, and in 1815, the Tambora volcano on Sumbawa Island erupted.

I am voting for low sunspot activity.  Your thoughts?

Deep Solar Minimum Fast-Approaching And Cosmic Rays Continue To Rise

By Paul Dorian, Perspecta, Inc. April 29, 2019

Overview

The sun continues to be very quiet and it has been without sunspots this year more than half the time as we approach what is likely to be a deep solar minimum. In fact, all indications are that the upcoming solar minimum which is expected to begin later this year may be even quieter than the last one which was the deepest in nearly a century. Solar cycle 24 has been the weakest sunspot cycle with the fewest sunspots since cycle 14 peaked in February 1906. Solar cycle 24 continues a recent trend of weakening solar cycles which began with solar cycle 21 that peaked around 1980. The last time the sun was this blank in a given year on a percentage basis was 2009 during the last solar minimum when 71% of the time was spotless. That last solar minimum actually reached a nadir in 2008 when an astounding 73% of the year featured a spotless sun – the most spotless days in a given year since 1913. One of the natural impacts of decreasing solar activity is the weakening of the ambient solar wind and its magnetic field which, in turn, allows more and more cosmic rays to penetrate the solar system. The intensification of cosmic rays can have important consequences on such things as Earth’s cloud cover and climate, the safety of air travelers and as a possible trigger mechanism for lightning.

The Sun’s Role in Climate Change

FORCE MAJEURE, THE SUN’S LARGE ROLE IN CLIMATE CHANGE (GUEST: HENRIK SVENSMARK), MAY 6, 2019

next_minimum_graphic1.jpg

A podcast interview of Henrik Svensmark by H. Sterling Burnett of the Heritage Foundation

By bombarding the Earth with cosmic rays and being a driving force behind cloud formations, the sun plays a much larger role on climate than “consensus scientists” care to admit.

The Danish National Space Institute’s Dr. Henrik Svensmark has assembled a powerful array of data and evidence in his recent study, Force Majeure the Sun’s Large Role in Climate Change. The study shows that throughout history and now, the sun plays a powerful role in climate change. Solar activity impacts cosmic rays which are tied to cloud formation. Clouds, their abundance or dearth, directly affects the earth’s climate. Climate models don’t accurately account for the role of clouds or solar activity in climate change, with the result they assume the earth is much more sensitive to greenhouse gas levels than it is. Unfortunately, the impact of clouds and the sun on climate are understudied because climate science has become so politicized.
