Some Questions About Climate Change
There are some questions that are very difficult to get answers to. In the climate change arena, since everything happens on a long time scale, it is hard to get answers to some simple basic questions. I will try and list some of them in this article. I hope to add to this list as time go by.

How Much Effect Does Volcano Eruptions Contribute to Climate Change?
This seems like a simple and basic question. However, the answer is not so easy. If you ask climate scientists, they will say all natural phenomenons are small compared to the human contribution. How come? Because they have eliminated those from their models as being too insignificant. Even the sun is not considered, since it is the source of all energy in our solar system, and for all intents and purpose, it is stable. However, we know this is not the case. The sun has a cycle which changes and repeats approximately every 11 or 12 years. It is called the sunspot cycle.
So, we are basically told by these scientists to ignore all natural phenomenon because their contribution to our climate change is minuscule. Yet, we have experienced extreme weather events in our own short history. Many of which are related to natural causes. One of those is extreme volcanic eruptions. It was documented that during the Krakatoa eruption of 1883, the whole world's weather was affected for several years afterwards. It was known as the year without summer, when the clouds and plumes from that eruption circle the globe for several years blocking out the sun and causing the average world temperature to drop a few degrees F.
Not to mention, 65 million years ago, apparently an asteroid struck the Yucatan peninsula and cause the distinction of the dinosaurs.
I read an article in a Scientific American magazine that was confusing. Here is an excerpt of it...
Why Is This Confusing?
We are told by climate scientists that human activities in the form of CO2 emissions can heat the earth 0.5 degrees C in 30 years or 2 degrees C in 100 years or so.
How come a simple volcanic eruption in 1991 can affect global temperature by 0.5 degees C in just a few years?
Yet, we are told natural causes like volcanos, earthquakes, or even the sun spots are too small to be considered.
Do you see the problem here?
Does it seem something that is obvious to all is being ignored by climate scientists in their complex models?
These same models are the basis for their extreme predictions going forward for 30-100 years.

What About the Sunspot Cycles?
We know the sun goes through a cycle approximately every 11 or 12 years. These spots are signs of magnetic activities within the sun which affects the radiation output generated by the sun. These cycles are very irregular and have been known to disappear at some times in the past. When the sun is quiet, it has an effect on our climate. This not not conjecture but proven and documented facts from our past.
A Daily Snapshot of the Sun
What Is the Contribution of the Sun?
Despite all the advances made in science and physics and astronomy, we have very little understanding of what makes the sun tick? We have very good observation data on the sun for the past 500 years or so. Those does not predict the future. Since the sun is responsible for all sources of energy and life on earth, you would think it is the primary cause of our planet's weather. Yet, we are told by climate scientists that the small variations are too small to be accounted. There climate models do not need the sun's variations to predict the future. Their main driver is CO2 or the green house effect. Why?
Why Were The Climate Models Off In Their Projections?
It is now 30 years since the global warming phenomenon. The climate scientists made a serious of projections back in the 1990s. They were all on the high side and in some cases double of the observations. How come? Shouldn't they explain what happened? What went wrong? and how they are going to fix it?
Instead, they seem to double down on their claims. They are now saying they were too conservative in their estimates. That going forward, things are going to escalate and cause much worse devastation than first anticipated. Based on what?

As we move further into 2020, solar activity dwindles. This year, solar activity will be marked as the lowest in over 200 years. The low in the sun's 11-year cycle will also have at least some repercussions for the climate here on Earth.
