Amid the dimmest Sun since 1978 – a month without sunspots

The sun today is cue-ball blank, a perfect unmarred sphere:


Solar Dynamics Observatory HMI Continuum

The sun has just passed an entire calendar month with no sunspots. The last time this happened, in August 2008, the sun was in the nadir of a century-class Solar Minimum. The current stretch of blank suns shows that Solar Minimum has returned, and it could be as deep as the last one.

The last time a full calendar month passed without a sunspot was August 2008. At the time, the sun was in the deepest Solar Minimum of the Space Age. Now a new Solar Minimum is in progress and it is shaping up to be similarly deep. So far this year, the sun has been blank 73% of the time–the same as 2008. 

Solar Minimum is a normal part of the solar cycle. Every ~11 years, sunspot counts drop toward zero. Dark cores that produce solar flares and CMEs vanish from the solar disk, leaving the sun blank for long stretches of time. These minima have been coming and going with regularity since the sunspot cycle was discovered in 1859.

Here’s the sunspot data:

Meanwhile, the sun is putting out less solar energy towards the Earth, as this graph of PMOD composite monthly total solar irradiance (TSI) data shows:

TSI in watts per square meter Graph source: http://www.woodfortrees.org/plot/pmod/from:1975

What is most interesting is in the PMOD ( Physikalisch-Meteorologisches Observatorium Davos (PMOD) composite ) TSI data, measured by satellites, and endorsed by NOAA, shows a drop of 2 watts per square meter since it’s peak around 2003, to the present in 2019, where in the last month, it has literally dropped like a rock, creating the lowest value in the dataset so far.

The estimate of increased solar forcing from increased carbon dioxide and other GHG’s in Earth’s atmosphere could be up to 3 watts/square meter if model estimates are to be believed:


Changes in radiative forcing of long-lived greenhouse gases between 1979 and 2012. 

This graph shows changes in radiative forcing of long-lived greenhouse gases between 1979-2012. These gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbon-12 (CFC-12), CFC-11, and fifteen other minor, long-lived, halogenated gases. The 15 other halogenated gases are CFC-113tetrachloromethane (CCl4), trichloromethane (CH3CCl3); hydrochlorofluorocarbons (HCFCs) 22141b and 142bhydrofluorocarbons (HFCs) 134a152a23143a, and 125sulfur hexafluoride (SF6), and halons 12111301 and 2402). The graph does not include other forcings, such as aerosols and changes in solar activity. Summary Total forcing in 1979 was 1.712 watts per square metre (W.m-2), and has steadily increased over time to 2.873 W.m-2 in 2012. Between 1979-2012, the largest contributors to radiative forcing have been CO2 and CH4. In 2012, the percentage contributions of each gas to total forcing was approximately: CO2: 64% CH4: 18% N2O: 6% CFC-12: 6% CFC-11: 2% 15 minor gases: 4% Forcing data are briefly summarized below. All the data are available in a later section as comma-separated values. The first value is the year, followed by forcing values (in W.m-2) for CO2, CH4, N2O, CFC-12, CFC-11, the 15-minor halogenated gases, and total forcing, respectively: 1979: 1.027, 0.419, 0.104, 0.092, 0.039, 0.031, 1.712 1980: 1.058, 0.426, 0.104, 0.097, 0.042, 0.034, 1.761 1990: 1.293, 0.472, 0.129, 0.154, 0.065, 0.065, 2.178 2000: 1.513, 0.494, 0.151, 0.173, 0.066, 0.083, 2.481 2010: 1.791, 0.504, 0.174, 0.170, 0.060, 0.106, 2.805 2012: 1.846, 0.507, 0.181, 0.168, 0.059, 0.111, 2.873References: Butler, J.H. and S.A.

It seems the sun has dimmed more than the usual amount at the end of solar cycle 24, and it could be a factor in the severe winter we are experiencing in many parts of the northern hemisphere.

EcoLiberty Conclusion: As Solar Cycle 24 coming to end maybe this year 2019. Solar Cycle 25 will soon begin. As we enter the solar minimum of the 21st century in this solar minimum Global economy be facing major hardship which and only a hand fill of people are aware of the oncoming solar and are prepare for it.

The oncoming solar minimum

The solar activity in a decline which that lead cooler climate on earth as well throughout the solar system the chart show the decline from solar cycle 22 to this current solar cycle 24; which has been the lowest a in century since solar cycle 14 which occur between March 1902 to June 1913. You can find out more on Wikipedia List of Solar Cycles Sun do goes thought cycles and there times when the sun be more active (more sunspots; resulting in warming throughout the solar system) and times when sun is less active (little to no sunspot; resulting cooling throughout the solar system).

Through history humans face times of Climate Optimum (eg Medieval Warm Period, Roman Warm Period, Holocene climatic optimum) they thrive because the climate is more favorable and able to grow crops and have great harvest; able to have society of health and growth.

When humans facing global cooling which that occurs when the solar activity is low (eg Wolf Minimum, Sporer Minimum, Maunder Minimum, Dalton Minimum which they occur during the little ice age) they face hardship like famine, disease and malnutrition because growing crops became more difficult or near impossible in most area because the climate is too cold and wet; that can affect the economy negativity that why empire and dynasty do collapse because cooling climate create hardships and the emperor is unable support his own empire. The chart below show the raise and fall of Chinese Dynasties. Which I got this image below form Ice age now website.

With the solar activity declining since solar cycle 21 we could be facing anther solar minimum which will result in cooling. The IPCC (Intergovernmental Panel on Climate Change) will not be predict that but instead keep us the dark as well as keeping us form knowing the truth. If we are enter in new solar minimum we will need to prepared. when solar cycle 24 coming to a close. The planet is already the affect of the oncoming solar minimum like crop loss and crop failure; that is the sign that solar minimum is near. The good that we have the technology that would help thrive during the solar minimum that is hydroponics and aqauponics which you can grow your plants indoor all year round free the elements.  The video below from Ice Age farmer is worth watching and I recommended that you watch it get some information.

Want to know more about the oncoming solar minimum and the little ice age I recommend subscribing to on You Tube

There would be more You Tubers cover the oncoming solar minimum and little ice age I let you decide on that one.

And now on; stay strong

Winter is coming: Earth awaits ‘mini ice age’ in 15 years, solar cycle study suggests

Earth is facing the prospect of a ‘mini ice age’ this century, with our sun’s activity projected to fall 60 percent in the 2030s, British astrophysicists say, based on the results of new research that they claim allows exact predictions of solar cycles.

Our planet is just 15 years from a new ‘mini ice age’ that could cause extremely cold winters characterized by the freezing of normally ice-free rivers as well as by year-round snow fields in areas that have never witnessed such climate conditions before, a group of astrophysicists claim.
