Back during last minimum there were no cell phones, air planes, Haarps, CERNS, nuclear weapons, nuclear power plants, internets, computers, phones, t.v.'s, cams, microwave ovens, microwave towers,
man made plastic trash, factory farms, satellites, pampers, rockets, lasers, automobiles, automatic and tech everything plus....tons and tons of man made useless junk made of
toxins, feces, blood and waste from all sorts of industries, modern hospital waste, pharmaceutical waste, cement cities to the max, pesticides, GMO's, bulldozers, experiments on earth's atmosphere,
incandescent light bulb, florescent lights, polluted waters, polluted soil, polluted air, Deforestation, electricity, radio's and radio towers, tons of paved roads and highways, loss of bees, radar, ozone
depletion, aerosols,...so on and so on and on and on and on and on and on..................To expect things to be the same during next solar minimum as the last on account of these and many more, is not
logical imo. The planets health is our health and planet earth is not healthy...on highway to hell kinda ride... destructive vineyard keeping. It's logical to me what's happening for myself I don't need
science to tell me what I feel, see and sense...and science is responsible for a lot of toxic waste also so there's that.

Global Warming vs. Solar Cooling: The Showdown Begins in 2020
By Mindy Weisberger February 09, 2018 Planet Earth
The sun may be dimming, temporarily. Don't panic; Earth is not going to freeze over. But will the resulting cooling put a dent in the global warming trend?
A periodic solar event called a "grand minimum" could overtake the sun perhaps as soon as 2020 and lasting through 2070, resulting in diminished magnetism, infrequent sunspot production and less
ultraviolet (UV) radiation reaching Earth — all bringing a cooler period to the planet that may span 50 years.
The last grand-minimum event — a disruption of the sun's 11-year cycle of variable sunspot activity — happened in the mid-17th century. Known as the Maunder Minimum, it occurred between 1645 and
1715, during a longer span of time when parts of the world became so cold that the period was called the Little Ice Age, which lasted from about 1300 to 1850.
But it's unlikely that we'll see a return to the extreme cold from centuries ago, researchers reported in a new study. Since the Maunder Minimum, global average temperatures have been on the rise, driven
by climate change. Though a new decades-long dip in solar radiation could slow global warming somewhat, it wouldn't be by much, the researchers' simulations demonstrated. And by the end of the
incoming cooling period, temperatures would have bounced back from the temporary cooldown.
Sunspots, which appear as dark patches on the solar surface, form where the sun's magnetic field is unusually strong, and the number of sunspots waxes and wanes in a cycle that lasts about 11 years,
fueled by fluctuations in the sun's magnetic field.
But during the late 17th century, the sun's spots all but disappeared. This episode corresponded with a period of exceptional cold in parts of the world, which scientists have explained as being connected
to the changes in solar activity.
Sunspot activity was high in 2014 and has been dipping ever since, as the sun moves toward the low end of its 11-year cycle, known as the solar minimum, NASA reported in June 2017. But a pattern of
ever-decreasing sunspots over recent solar cycles resembles patterns from the past that preceded grand-minimum events. This similarity hints that another such event may be fast approaching, the
researchers reported in the study.
And the scientists have estimated how intense such an event might be, by analyzing close to 20 years of data recording radiation output from stars that follow cycles similar to that of our sun. Solar
radiation output typically drops during a normal solar minimum, though not enough to disrupt climate patterns on Earth. However, UV radiation output during a grand minimum could mean activity
plummets by an additional 7 percent, the researchers wrote in the study. As a result, air temperatures on Earth's surface would cool by as much as several tenths of a degree Fahrenheit (a change of a
half-degree F is the equivalent to about three-tenths of a degree Celsius) on average, according to the study.
The study's findings will help scientists create more accurate climate model simulations, to improve their understanding of the complex interplay between solar activity and climate on Earth, particularly in
a warming world, the study's lead author, Dan Lubin, a research physicist with the Scripps Institution of Oceanography at the University of California, San Diego, said in a statement.
"We can therefore have a better idea of how changes in solar UV radiation affect climate change," he said.

Hi Eve,
I believe it would be possible to have a technologically advanced
civilization which does not produce the immense damages and
mountains of destructive garbage.
But it would take a reorientation of the mind, away from money,
power, greed in all forms, and above all egotistical behavior which
transcends just about everything.
I have never understood why competition should produce better
results than cooperation. Nature does not compete with herself
anywhere. Wherever I look I see cooperative forms in many
shapes, sizes, time spans, among wild plants, animals, rivers,
mountains, rivers, wind, sun, clouds, soil. On all scales from the
tiniest microbes to planetary and galactic systems you can find
well-balanced cooperation of natural forces.
It is quite obvious that humans have chosen a wrong path which
started not just yesterday, but millenia ago. The power of the ego
has dominated the development of civilizations since long before
the great pyramids.
The great library in Alexandria, Egypt was likely burnt down to
destroy important ancient knowledge.
Unless humans soon find ways to clean up their mess and return to
nature's ways it will be nature who cleans up.
The sun will likely play an important role since it produces and
sends to earth all the light energy necessary to grow whatever
needs to grow to sustain flourishing life.
Whenever solar energy output is diminished the effects are felt on
earth, on various time scales from a few minutes, the time it takes
the light to travel from the sun to earth, to weeks, months, years,
decades.
When clouds obscure the sun the amount of light available for
growth is sharply reduced immediately. Yet, as mentioned in the
article on my recent post on earthwatchers, the global warming
protagonists simply ignore the effects of varying low cloud cover
when analysing temperature trends.
It really amazes me that no one but you responded in any way to
that post which essentially says that the amount of low cloud
cover completely determines the temperature on earth and that
the sun's behavior is directly affecting earth's low cloud cover.
And the second article that I posted in that thread supports the
conclusions of the first by analysing close relationships between
environmental data in East Asia over many decades about 700
thousand years ago.
It is an intricate balance of natural environmental factors which
provides the foundation for life on earth. Most humans are not or
no longer aware of this simple fact. So they go about their daily
lives as if they can do whatever they want to keep their egos
happy and their bank accounts healthy.
