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
