We all need to be concerned about the impact of human activities on climate change, but the media hype suggesting that global warming is something new is simply not true. Science News magazine reported data on global warming in the past, going back to the Paleozoic era over 485 million years ago.
The data show that temperatures reached nearly 95 degrees Fahrenheit (35 degrees Celsius) three different times in Earth’s history. The time of the coolest temperatures is the period in which we are living. Earth cooled about three million years ago, reaching 53.6 degrees Fahrenheit (12 degrees Celsius). According to NASA, the present average global surface temperature is 59 degrees Fahrenheit (15 degrees Celsius). It appears that our planet is heading into a warm cycle, which humans contribute to, but they are not the only cause.
The media and politicians sometimes present an alarmist view of the future to attract more attention. There has been global warming in the past, and while humans will be affected by future climate change, there are many contributing factors.
How old is planet Earth? Why does it matter? Various branches of science agree, based on substantial evidence, that our planet is about 4.5 billion years old. Many Christians argue that it is only a few thousand years old, and they make it a matter of faith. In other words, if you disagree with their timeline, you are an evolutionist and Bible denier. Scientists have methods for calculating Earth’s age, and they have nothing to do with faith or denying the Bible. The truth is that Earth’s age is irrelevant to Christian faith.
Why do many Christians insist on a “young” Earth? It may be because they believe the Bible says so. They base that on a document written by an archbishop of the Church of Ireland, James Ussher, published in 1654. He calculated that Earth’s creation took place on October 22, 4004 B.C. He based his calculations on the assumption that the genealogies of Genesis are complete and that they are recorded for the purpose of chronology. Those assumptions are not correct. The biblical genealogies are incomplete, and their purpose is to show lineage, not chronology. Of course, the lineage eventually led to the Messiah. Because early English translations of the Bible included Ussher’s chronology, many came to believe it was the gospel truth.
Another significant reason many Christians today choose to believe in the young-earth doctrine is that they think it refutes evolution. Scientists don’t insist on billions of years to allow time for evolution. A little-known fact that scientists are reluctant to admit is that 4.5 billion years is not long enough for unguided evolution to create the diversity of life on Earth today. In reality, no amount of time is sufficient for random mutations and natural selection to accomplish the task. But not all of the 4.5 billion years are available for evolution. A large amount of time would be required for the planet to cool and become suitable for life. Then, more time would be needed for non-living elements to organize themselves into the first living cells. (They couldn’t do it by themselves in any amount of time, but that’s another issue.)
The bottom line is that Earth’s age is irrelevant to Christian faith. The age of the Earth is essential to the sciences of geology, paleontology, astronomy, physics, chemistry, and others. As it relates to the Christian faith and the accuracy of the Bible, Earth’s age is irrelevant and always will be. Archbishop Ussher was an intelligent church leader and scholar, but his chronology fails because he based it on false assumptions. False assumptions lead to false conclusions.
If you’re thinking that you didn’t accomplish much yesterday, August 5, 2025, it might be because the day was shorter than usual. I don’t mean that the daylight hours were shorter. Earth’s solar day was shorter than the typical 24 hours, which equals 86,400 seconds. You probably didn’t notice because the day was only 1.25 milliseconds shorter. Blaming the shortest day won’t help—you’ll need to find some other reason for not achieving more.
Earth’s rotation speed had been gradually slowing down, but for some reason it started speeding up in recent years, making the days shorter. Official and precise records of solar day lengths since 1973 show that they were getting longer. Earth’s gravity creates friction against the Moon, causing it to drift farther away and slowing Earth’s rotation. A slower rotation results in longer days.
The Moon’s position relative to Earth’s equator creates tidal forces that very subtly influence Earth’s rotation rate. Scientists speculate that the slower rotation of Earth’s liquid core might cause the outer layers of the planet to spin faster, but that remains only speculation.
We can’t really say that yesterday was the shortest day because July 5, 2024, was 1.66 milliseconds shorter than the usual 24 hours. Don’t worry about any noticeable change in the length of days. God has given us an incredibly stable planet on which to live. Many finely tuned factors make life on Earth and our existence possible, and it could not have been accidental. This remarkable planet is further evidence that God exists.
Thornton Reef Quarry with Interstate 80/294 crossing it
Scientific American magazine reported that if the entire Greenland ice sheet melted, global sea levels would rise by 24 feet. The article clarified by saying, “The sheet won’t melt all at once, of course…” What articles like this fail to convey is that Earth has experienced radical sea level changes throughout both geologic and human history.
Geologic history shows marine deposits in places you wouldn’t expect. When I taught earth science, I took my classes to Thornton Reef on the south edge of Chicago, Illinois. I am told that the gravel pit now occupying the reef is the largest in the United States. On one trip there, a student found the tube of a cephalopod, an ancient giant octopus-like creature. Clam shells, snail shells, and brachiopods filled buckets that my students took home. This reef is similar to modern ocean reefs, except it winds through the south side of Chicago with a major interstate highway running right through it.
Other examples of historic radical sea level changes are abundant. Oolitic limestone in southern Indiana consists of tiny ocean creatures called oolites. The limestone in the Grand Canyon contains marine deposits. On the other end of the scale, canyons are cut into continental shelves along the U.S. East Coast of the United States. Those canyons were cut when the shelf was out of water. Scuba divers have reported signs of ancient human-made structures and fire pits in those canyons.
Was the Red Sea at the same level when Moses led the Israelites across? Are people searching for Egyptian armor and chariot remains in the wrong spots? The “Sea of Reeds” was likely dry land at that time, so efforts there are probably doomed to fail. We still have much to learn about climate history, radical sea level changes, and ancient peoples. As our technology improves, discoveries will increase, and we look forward to uncovering more evidence of Earth’s history.
One of the challenges that we all face is dealing with disasters such as tornadoes, hurricanes, and floods. Skeptics claim that if a God exists, He wouldn’t allow these terrible natural disasters to take place. That claim displays a combination of scientific and theological ignorance.
Tornadoes result when hot air is trapped under a layer of cold air. Warm air rises, but if the cold air above it is dense enough, the warm surface air will become even warmer. Eventually, the hot air will rise through the cold layer. Hang glider pilots and soaring birds look for these vertical updrafts. When the ground is covered with vegetation, there is never enough heat to trigger a strong upward air movement. However, when thousands of acres of land are plowed up or paved over, the surface air becomes hotter and creates stronger vertical movement. Earth’s rotation spins these upward air movements, creating a tornado.
Areas around 30 degrees north and south latitude are usually deserts. The states of Florida, Georgia, Mississippi, and Alabama are at or near 30 degrees north latitude. Hurricanes pick up massive amounts of water from the ocean and dump it on the land. Without hurricanes, there would be a water shortage in many places. In the past, storm surges were not a problem because the coastal areas were lined with mangroves and other plants on the barrier islands and along the mainland coast. Today, that protection has been stripped away and replaced with hotels, roads, parking lots, and beach-front homes. The result is that we are dealing with disasters.
God told humans to take care of the Earth, but greed, selfishness, and ignorance have often caused disasters. The more we learn about the creation, the more we understand that God designed it to work well, but humans have brought much pain and suffering on ourselves by misusing God’s gift. We must work together and avoid repeating past mistakes, or we will continually be dealing with disasters.
As a high school physics teacher, I frequently found myself challenged to keep my students interested. Some subjects were easy, but others were challenging, and the kids became bored very quickly. An example of the latter was a unit on the laws of thermodynamics. The second law, also known as the entropy law, states that a closed system tends to become increasingly disordered over time. Entropy is a statistical measure of disorder. During that unit of study, I once had a student who said, “Who cares?” There are good reasons why we care about entropy.
My response is that entropy is a design feature of the cosmos that produces black holes, but it also allows us to breathe and have engines in our cars. As a public-school teacher, I could not bring my religious views into the classroom, but it also disproves one of the atheist arguments against the existence of God.
When we say that God has always existed and He created the cosmos, atheists ask, “Then who created God?” They suggest it is easier to believe that matter has always existed. Why we care about entropy is that it shows that matter and the cosmos have not always existed.
Every reaction in the physical world reduces the amount of energy available to do work. The total energy in the cosmos available to do work is constantly decreasing, eventually becoming zero, and entropy will be maximum. That means the cosmos could not be eternal, and it must have had a beginning. There must be a cause for that beginning, and that cause is God.
Living on a river that feeds Lake Michigan, we tend to ignore messages of water shortages. There is some irrigation in our area, but nothing like what we see in other regions of the world. Recent studies of global soil moisture show a very different picture.
Drought events at various global locations have caused the loss of 1.614 gigatons of water between 2000 and 2002. (One gigaton is one billion tons.) In the United States, irrigation has been highly contested as rivers in Nebraska and Colorado cannot supply the water needed to grow wheat and other grain crops. Drawing from the water table has caused it to drop over 10 feet in recent years.
Studies at the University of Texas and Seoul National University show that the problem of water shortages will cause more hunger and human suffering if we don’t do something to stop the soil moisture loss. The solution to water shortages is available.
There was no way to recover water lost to the oceans in the Old Testament days, but now there is. We can use nuclear energy and various processes to desalinate seawater. Removing the salt from seawater provides the salt humans need while producing fresh water for irrigation and replacing soil moisture.
God has provided humans withthe water we need. In ancient times, humans lived by bodies of fresh water. With the expanding human population, not everyone could live on the shores of lakes or along rivers, so water had to be moved from places of plenty to places of drought. The Romans did this with aqueducts stretching for miles. In the western United States, we can allow rainfall and mountain ice melt to replace soil moisture while supplementing the need for water in cities by the ocean, like Los Angeles, using desalination.
The teachings of Jesus were ones of peace and concern for others. Water shortages have fueled greed and rivalry in areas of our planet. We need to use the nuclear energy God has given us to desalinate water rather than as a tool of war.
One of planet Earth’s many unique design features is the atmosphere’s circulation pattern, allowing advanced life to exist on our planet. This pattern was first noticed in 1735 when George Hadley was working with the motions of wind recorded by scientists. Realizing that wind currents were not just accidental, he originated the idea of what we call Hadley cells. We know today that the circulation of the atmosphere is much more critical and complex than anyone understood in Hadley’s day.
A feature designed into Earth’s weather pattern is how the insolation moves daily. Insolation is the amount of solar radiation that reaches the surface of a planet. Of the other planets in our solar system, only Mars has a tilt, which spreads the insolation from one latitude to the next, but Mars does not have enough atmosphere for this to be a significant factor. The other planets don’t change their tilt, so the Sun’s radiation is constantly over one latitude. The temperatures at that latitude climb very high, and everywhere else is unbelievably cold.
On Earth, the Sun’s energy gradually changes daily, moving to 20 degrees north or south latitude and striking at the Earth’s equator only two times a year. The Sun is over the equator at the equinoxes on about March 20 and September 22, and the day and night length is the same. Around June 21, the Sun is as far north as it gets, and around December 22, it reaches its southernmost point.
In the Hadley cells, air rises in tropical zones, where it drops its moisture as it cools. At 30 degrees latitude, the cooler air sinks and has very little moisture. Virtually all of Earth’s major deserts are around 30 degrees latitude north and south. In the western United States, we find the Mohave Desert, but the eastern U.S. does not have a desert even though it is at 30 degrees. Hurricanes and the Atlantic Ocean bring a large amount of water to states located at 30 degrees latitude in the eastern U.S. So many things make advanced life possible on this planet that trying to attribute all of them to chance requires far more faith than believing that God designed and created the weather on Earth so you and I can exist.
It is amazing to see that some people in the religious community are making climate change an issue. As a public school teacher, I can attest that this destructive attitude is often a result of ignorance. Is climate change happening? The answer is yes! Is this the first time humans have had to deal with changing climate nonsense? The answer is no! It would help if religious people would read their Bibles and not rely on religious con artists for their belief systems.
In Genesis 41:53-57, we read about Joseph and the drought that led to famine in Egypt and its neighboring countries. This was not due to insects or war but to climate change. Second Samuel 21:1 and Jeremiah 14:1-6 recount droughts that significantly impacted the history of Israel. Those of us who are older will recall the Dust Bowl era in the United States, which drove many farmers to California due to the changing climate affecting the central part of the Country.
The public schools need to educate young people on the history of climate change in America’s past because we are entering a period of intense changing climate. It is a scientific fact that the climate is changing worldwide. Areas of the United States that were once deserts are now receiving rain, which alters the animal and plant life in those regions.
The water levels in Lake Michigan have changed dramatically over the course of my lifetime. I used to take my earth science classes on field trips to Lake Michigan. We had been experiencing climate change in those days, which produced unusual amounts of moisture, and the lake was higher than at any time in recent history. Houses built along the lake when the water was low were being threatened by erosion. One place I took my classes to was Michigan City, Indiana, where I knew property owners were battling the higher water levels. As we stopped to look at the beach, a more expensive house than any of my students lived in suddenly slid into the Lake right in front of us.
The causes of climate change are very complex. The extent to which human activity contributes to climate change is a subject of debate, but it is certainly not the only cause. When today’s children face a changing climate, we hope they will be better prepared to adapt to it than their parents were. We all must be prepared in advance for a changing climate.
Yesterday, we told you that the total lunar eclipse visible in the Western Hemisphere last night was connected to the eclipse of 1504, which Christopher Columbus used to get the supplies he needed from the people of Jamaica. It’s an interesting story that you can read HERE. What can we learn from a lunar eclipse, and what is the connection between the eclipse of March 13-14, 2025, and the eclipse of March 1, 1504?
Eclipses come in groups or families called saros. One saros is approximately 18 years, 11 days, and 8 hours, slightly varying depending on the number of leap years. The end of each saros has an eclipse similar to the one at the beginning. Astronomers use saros to predict when an eclipse will occur.
A hypersaros consists of multiple saros cycles and lasts for 521 years. Eclipses separated by one hypersaros will appear very close to the same location in the sky and occur at nearly the same time of year. How far apart are 1504 and 2025? They are separated by 521 years, and both eclipses occurred in March about two weeks apart.
This means the eclipse of 1504 would have appeared in the same location in the sky. If you saw last night’s eclipse, you would have seen the same stars surrounding the blood moon as the natives of Jamaica saw 521 years ago. You had a chance to learn from a lunar eclipse by reliving the historical event of 1504.
Chances are you didn’t watch last night’s eclipse for the full length of totality—about an hour. However, I am sure the Jamaicans continued to watch it as they agonized in fear. Meanwhile, Columbus sat smugly in his quarters, watching his hourglass to know when the eclipse would end. Then, he could emerge to tell the natives that God accepted their apology and would restore the Moon.
You can certainly question Columbus’s tactics and his deception of the Jamaicans, but we can learn from a lunar eclipse. The pagan islanders were fooled because they were ignorant of science. Knowledge of science gave Columbus the edge. Knowing that God has designed an orderly and predictable solar system and universe frees us from the ignorance of worshiping His creation. It also frees us from believing that so-called “blood moons” are some special sign. They are part of the system God designed, making them predictable.
We can see God’s eternal power and divine nature by the things and systems He has made (Romans 1:20). The laws that govern the universe show fine-tuned design. The cosmos is not chaotic. It is the work of a God who has a plan and purpose for each of the human creatures He created in His image.
P.S. As I watched the total eclipse at about 3:15 a.m. my time, a meteorite appeared just below it. I suspect that did not happen to the Jamaicans, but it could have. For more about “blood moons” and “shooting stars,” read THIS POST. R.E.
