Heat From Deep Ocean Fault Punches Hole in Arctic Ice Sheet

This a report from the Climate Change Dispatch that I found very interesting. Some reader many know the details as it is from a November 2015 post.

Powerful deep Arctic Ocean geological heat flow forces have just sent us a very obvious signal, but are climate scientists listening? The answer is no, however geologists hear it loud and clear!


Figure 1

As winter begins to settle in across the Arctic Ocean and sea ice extent rapidly expands, a very interesting high temperature and low salinity hole has just been punched in the sea ice at a very telling location: directly above the deep ocean Gakkel Ridge Rift / Fault System (Figures 1, 2, and 3 in the original post).

This world class plate tectonic pull-apart rift is a 1,000-mile-long fault system on the seafloor that has in recent past pulsed massive amounts of heat into the overlying ocean and thereby melting large portions of the ice that floats above the heated ocean column.

So what if anything is to be learned from the recent October 12 geologically induced deep-ocean floor heat pulse that punched a small hole in the Arctic sea ice? Many things, most of which have surprisingly large implications concerning the entire climate change discussion.

Here is how it works:

Climate scientists who favor the theory of man-made global warming have maintained for many years that the accelerated melting rate of the Arctic sea ice during the 1999-2007 time period was entirely due to man-made CO2 emissions which acted to rapidly warm the atmosphere. This unusual Arctic melting was greater than the melting rate associated with Earth’s ongoing and very normal 11,500-year-long post-glacial period melt rate.

Many climate scientists have begrudgingly stuck to this human-induced atmospheric warming story even though diverse and compelling amounts of data have now cast serious doubt on this hypothesis. It is clear to most scientists that non-atmospheric natural forces play the dominate role in driving sea ice extent and thickness such as well known variations in Earth’s astronomical orbit patterns, long-term cyclic changes in deep-ocean current patterns, and most importantly variations in geologically induced heat and chemically charged fluid flow from deep ocean faults and volcanoes (see previous CCD posts).

The small geologically induced deep-ocean heat and fluid flow event of October 12 eloquently demonstrate that geological forces are still active and have the power to alter Arctic climate and climate-related events, melt sea ice.

Keep in mind this latest October 12 event is not associated with obvious earthquake swarms and proven volcanic eruptions as was the case during the 1999 – 2007 event. This earlier event was powerful but not obvious to those who did not understand its true nature. Even though it was associated with an extensive low-intensity earthquake swarm, a huge methane release, and a significant series of volcanic eruptions along the Gakkel Ridge it was, and still is dismissed as insignificant by most climate scientists advocating the theory of man-made global warming.

However, many other scientists now realize that the 1999-2007 Gakkel Ridge heat and chemically charged fluid flow event was the root cause of accelerated the Arctic sea ice melting rate. An event that fits well with the Plate Climatology Theory, geological forces strongly influence climate.

The question is what role did Plate Climatology play in Grand Minimums, what could it play in the Next Grand Minimum?

Volcanos and Climate Change

Cross posted from Sierra Foothills Commentary.

Sierra Foothill Commentary

It is not clear why, but when the earth cools and sunspots are at their minimum, volcanic activity on earth seems to increase, especially super volcanos that leave a significant eruption signature. See graphic below:

Volcanic activity
The most dangerous super volcano in the US is a volcanic plume that has been sliding northeast, across Idaho for millions of years and last erupting about 640,000 years ago in north-western Wyoming. The Yellowstone Caldera was created by a massive volcanic eruption approximately 640,000 years ago. Subsequent lava flows filled in much of the caldera.

UK Express has a volcano warning:

Instances of volcanic eruptions are their highest for 300 years and scientists fear a major one that could kill millions and devastate the planet is a real possibility.

Experts at the European Science Foundation said volcanoes – especially super-volcanoes like the one at Yellowstone National Park, Wyoming, which has a caldera measuring 34…

A Quiet Sun is Coming and so is a Cold Climate According to Study

Extracts from a press release from Lomonosov Moscow State University

The Sun’s behaviour in future cycles is the main theme of a publication on the forecast and explanation of the minima of solar activity. The paper was prepared with contributions from Elena Popova from the Skobeltsyn Institute of Nuclear Physics (Lomonosov Moscow State University) and was published in Scientific Reports.

Scientists have studied the evolution of the solar magnetic field and the number of sunspots on the Sun’s surface. The amplitude and the spatial configuration of the magnetic field of our star are changing over the years. Every 11 years the number of sunspots decreases sharply. Every 90 years this reduction (when it coincides with the 11-year cycle) reduces the number of spots by about a half. A 300-400 year lows reduce their numbers almost to zero. Best known minimum is the Maunder minimum, which lasted roughly from 1645 to 1715. During this period, there were about 50 sunspots instead of the usual 40 000-50 000.

Analysis of solar radiation showed that its highs and lows almost coincide with the maxima and minima in the number of spots. By studying changes in the number of sunspots, analyzing the content of isotopes like carbon-14, beryllium-10, and others, in glaciers and trees, the researchers concluded that the solar magnetic activity has a cyclic structure.

A group of scientists – Valentina Tarasova (Northumbria University, England, Space Research Institute, Ukraine), Elena Popova (SINP, MSU), Simon John Shepherd (University of Bradford, England) and Sergei Zharkov (University of Hull, England) – analyzed three solar activity cycles from 1976 to 2009, using the so-called “principal component analysis”, which allows reveal waves of solar magnetic field with the biggest contribution in the observational data. As a result of a new method of analysis, it was found that the magnetic waves in the Sun are generated in pairs, and the main pair is responsible for changes in the dipole field, which is observed when solar activity is changing. Also scientists have managed to obtain analytical formulas describing the evolution of both waves.

Using empirically found two waves of the magnetic field, Elena Popova hypothesized that the minima of solar magnetic activity can be caused by the process of the beating of these two waves. Each wave is generated at different depths in the Sun and the waves have similar frequencies. As a result of ascent of the magnetic field on the surface the waves begin to interact which ends in beating of amplitude of the resulting magnetic field. This leads to a significant decline in the amplitude of the magnetic field for several decades. Comparison of the results of the model was carried out both with an array of observed magnetic field data for cycles 21-23, and with the observed data of solar activity over 1000 years. On this scale the model calculations of Popova were very close to the characteristics of solar magnetic activity.

By highlighting the indicative period of the beats (which is about a few centuries), scientists have reconstructed solar activity since ancient times (starting from the year 1200) and predicted it until the year 3200. The given chart shows that solar activity decreases dramatically about every 350 years. And upcoming decrease in solar activity begins nowadays.

Will all this affect the weather on Earth?

“Studies have shown that over the last 400 000 years there were 5 global warming and 4 ice ages. What caused them? How much can solar activity affect the weather and climate change? This question is still not solved and is extremely relevant and interesting challenge for the various researchers around the world. There are a number of theories that suggest very different degrees of influence of solar activity on weather and climate. In addition to solar activity, climatologists offer other factors that may affect the dynamics of Earth’s climate system. Such a system is a very complex nonlinear system, and further use of numerical simulation and analysis of paleodata can help in the investigation”, says Elena Popova. “If in the near future there would be a minimum of solar activity, it would give an opportunity to see what happens with the climate dynamics and test existing theories about the influence of solar activity. Actually, even if we start from the simple knowledge of the cyclicality of the Sun, it can be said that it’s already time for hundred-year-minima – the previous one has happened in the beginning of XX century. Of course, it is necessary to take into account the effect of other factors and processes in the atmosphere; however, the challenges have always intrigued scientists”.

Climate and Human Civilization over the last 18,000 years

I recommend readers examine this post at WUWT as it puts multiple grand minimums in perspective, in that they follow long warm periods which promoted human growth and expansion. It is interesting to note that the cold periods were accompanied by long-term droughts. Droughts that disrupted civilizations and in many cases promote collapse. Highly recommend reading.

A Dalton-like Amplitude for Solar Cycle 25

Some insight into potential solar activity during the next solar cycle. A Dalton Minimum will most likely not be as severe as a Maunder. Only time will solve the issue.  The comment discussion is most interesting, highly recommended reading.

Watts Up With That?

Guest essay by David Archibald

The most accurate method for predicting the amplitude of the next solar cycle is to use the strength of the solar polar magnetic fields at solar minimum. But with solar minimum likely to be three years away, who can wait that long?

The strength of the solar polar magnetic fields at solar minimum is a very accurate indicator of the maximum amplitude of the following solar cycle, as per this graph from Dr David Hathaway of NASA:


Up until late 2014, solar polar magnetic field strength was still quite weak as shown in this graph of the history of that parameter by solar cycle from the last four solar minima:


Over the last year the solar polar magnetic fields of Solar Cycle 24 have strengthened to almost the level of Solar Cycle 23 at the same stage. But for the previous two cycles, they also…

1709; The Disparate Economic And Political Impact of Weather And Climate

I have reblogged this post by Tim Ball from WUWT so readers can read about the climate during the Little Ice Age and the Maunder Minimum. We might see a repeat of these climate conditions during the Next Grand Minimum, although we will have modern heating systems, if we still have some oil and coal to fire the boilers.

New studies flip climate-change notions upside down

The Nation: Cold Sun rising

The sun will go into “hibernation” mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society’s annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it – the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova’s model is said to have near-perfect accuracy.
