We have previously discussed the movement of air around the Earth, and the circulation pattern called the Hadley cells. Another important factor in Earth’s climate is Rossby waves.
Because the equator is hot, heated air rises and moves away from the equator, dropping its moisture as it cools. At about 30 degrees latitude, the now dry air falls back to the Earth, producing deserts. As the air reaches Earth’s surface, it moves north and south, creating the trade winds in the subtropical area and the prevailing mid-latitude winds in latitudes between 30 degrees and the polar regions.
A wide range of things alters this simplified picture. When greenhouse gases like carbon dioxide accumulate, they reflect infrared radiation causing the Earth’s atmosphere to become hotter. This effect isn’t uniform, however. Because of melting sea ice, Earth’s poles are affected by greenhouse gases more than the area of the equator. This causes a thermal imbalance between the poles and the equator affecting circulation around the poles and creating Rossby waves.
As the thermal imbalance has become greater and the air more wobbly in recent years, that affects the jet stream. The wobbles this past year have caused the northern jet stream to go further south than usual, bringing cold into Arizona in late spring. When the jet stream swung north, it brought hot tropical air toward the poles. On its way north, it brought unusual amounts of water into Oklahoma while Anchorage, Alaska, got temperatures over 90 degrees for the first time ever. Rossby waves is the name applied to the meandering high-altitude winds that have a major influence on Earth’s weather.
All of this shows us how fragile Earth’s climate is. Weather patterns depend on a wide range of variables which include the:
*size of the Earth’s atmosphere
*tilt of the Earth
*distribution of land compared to water
*chemical makeup of the atmosphere
*kind of radiation coming from the Sun and how that radiation is absorbed and reflected
*nature of Earth’s surface (whether ice or black dirt)
All of those factors go into making Earth a habitable planet.
We exist on this planet because of the precision design and construction of Earth and its atmosphere. The fact that it has stayed stable long enough for human life to exist for thousands and thousands of years is a testimony to the careful design and construction. Proverbs 8 finds “wisdom” speaking about its role in the creation process. Wisdom says she was there before the creation (verse 22-23) and that wisdom was a part of the preparation of the heavens (verse 26-28).
As we see the results of the small changes that have happened to the atmosphere in the past 100 years and the instability of Rossby waves, we wonder at Earth’s design and the wisdom of God who created it.

Why do humans have different races and skin colors? If we all came from “Mother Eve,” should we not all be the same color? In the past, some people suggested that people of other races were not really human, and they used that argument to justify everything from slavery to infanticide. What is the truth about race and skin color?
For 51 years, we have presented public programs on scientific evidence for the existence of God and the validity of the Bible. During that time, we have seen a lot of violence, going beyond verbal threats. I have had a pie thrown at me during a lecture. Someone smashed the windows of my truck with a hammer. Personal property at my home was set on fire. In a few situations, I have been shoved, pushed, or hit with a stick. Those incidents have always involved disgruntled individuals with an ax to grind who felt that I was persecuting them. In each case, the damage was minimal. Receiving threats is common for anyone who takes a strong position on God or politics. The frightening polarization and violence is a whole different matter if those threats are physically carried out.
A U.S. Census Bureau report released September 25, 2019, says that the number of unmarried partners living together has tripled in the past two decades. The report says that the number went from 6 million in 1996 to 19.1 million in 2018. There are all kinds of editorials about this data, with some writers referring to it as “increasing normalization.” The report comments that people who cohabitate are “older, better educated, more likely to earn higher wages and more racially diverse.” The report also says that cohabitation is “an alternative to marriage for low-income and less educated people.” What is the truth about marriage versus cohabitation?
Recent events have led us to consider the question, “Has society lost the value of human life?” There were two events in the news this past week that certainly seem to indicate where society is going.
The average person has difficulty getting reliable information about what is actually going on in our schools, courts, and legislatures. The 
We can’t win with the atheist press, because atheists attack us for anything we do or anything we don’t do. If Christians are not involved in the latest natural disaster relief effort, atheists criticize that non-involvement. They ignore the fact that virtually no atheist organization has ever consistently engaged in disaster relief. When Christians are involved, critics question their motives and 
America’s first official “non-binary” person was a man named James Shupe, a retired Army officer who in 2014 announced that he was a transgender woman. Two years later, as Jamie Shupe, he/she petitioned an Oregon Court to be recognized legally as “non-binary” – neither male nor female. The court in Multnomah County granted the request. Some states have now put the “non-binary” option on driver’s licenses as a result of that decision. The question becomes, “What happens when a transgender person changes his/her mind?”
One of the major efforts of this ministry is to provide educational materials and support for men and women in prison. The United States has the largest prison population in the world, both numerically and in the percentage of the nation’s population. For that reason, workers are greatly needed in prison ministry.
