Trees Prepare for Winter

Trees Prepare for Winter

Imagine standing naked outside on a cold winter day. When winter’s chill comes, people take shelter. If we have to be out, we put on more clothing. Most animals have fur or feathers to help keep them warm, and they also seek shelter from the cold. Trees in winter can only stand there and take it for months at a time. So how do trees prepare for winter?

Living cells in plants or animals consist primarily of water inside a membrane. If you leave a bottle of water in your car on a night when the temperature drops below freezing, you know it will freeze and break the bottle. That is because water has the unique property of expanding as it freezes. The same thing can happen in living cells. If the water in the cell freezes, it will expand and rupture the membrane. Animals that are endothermic (warm-blooded) generate heat within their cells by burning sugar to produce energy. Plants make sugar using light energy. With a few exceptions, they don’t produce heat.

How do trees prepare for winter? They use a process botanists refer to as “hardening.” The cell walls become more permeable to allow water to escape. At the same time, sugars, proteins, and acids in the cell are concentrated into a syrupy liquid, which acts as an antifreeze. The spaces between the cell walls become filled with ultra-pure water filtered through the cell walls. Pure water without stray atoms to form a nucleus around which ice crystals can grow, will freeze only at a much lower temperature. With the cells filled with antifreeze and spaces between having only ultra-pure water that can be super-cooled without freezing, the tree is ready for what the winter brings.

How does the tree know that it’s time to harden for winter? Fall weather can fluctuate quickly and dramatically. A tree can’t depend on the fickle weather because it could easily be fooled by warm days that suddenly turn cold, causing it to freeze to death. Trees know when to prepare for winter because of the length of the days – the “photoperiod.” Weather is unpredictable. The Sun is absolutely dependable. When the tree senses a decrease in light in each 24-hour cycle, it knows winter is coming, even if the weather is unusually warm. The pattern of changing daylight and darkness is exactly the same every year, even though the weather is capricious.

God engineered this incredibly well-designed system. “Then God said, ‘Let there be lights in the expanse of the sky to separate the day from the night. They will serve as signs for seasons and for days and for years’” (Genesis 1:14). Thus God designed the system which says, “Trees prepare for winter.” It’s another engineering marvel from the Creator.

Rossby Waves and Earth’s Climate

Rossby Waves and Earth's ClimateWe 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.

What the Mercury Transit Tells Us

What the Mercury Transit Tells UsAbove is a photo of the Sun. If you look closely, you will see a small dot in the upper half near the right side. That is the planet Mercury, the closest planet to our Sun. Mercury made what astronomers call a “transit” of the Sun on Monday morning, November 11, 2019. In our area of the country, the sky was overcast, and it was snowing. However, Bill Ingalls of NASA took this photograph from his location in Arlington, Virginia. I find it interesting to consider what the Mercury Transit tells us.

What’s so special about Mercury passing in front of the Sun? For one thing, it doesn’t happen very often. Although the last time was only three years ago, the next time will be in 2032, but it won’t be visible from North America. The next Mercury transit visible in North America will be in 2049. Since Mercury is closer to the Sun, it passes between the Sun and us every 116 days. However, most of the time, it is either above or below the Sun from our view, and Earth’s atmosphere makes it invisible in the daylight.

Scientists used precision telescopes and equipment to study the transit. They can learn more about the atmosphere of Mercury as it is silhouetted against the Sun. Historically Sir Edmund Halley (1656-1742) watched a transit of Mercury and realized that it could be used to measure the distance between the Earth and the Sun. It occurred to him that a transiting planet would appear in different positions to viewers in different locations on Earth. Measuring the apparent shift between two distant Earth locations at the same time and applying a little math, one could calculate the distance to the Sun. In 1769, after Halley’s death, astronomers used a transit of Venus to calculate the Earth-Sun distance.

Think about what the Mercury transit tells us without even seeing it? Because of the fact that astronomers can know in advance the exact date and time of a transit of Mercury (or Venus), or a solar eclipse (when the Moon passes between Earth and Sun) we realize that the solar system is orderly. We can study the heavens and learn of the Creator. We can see His wisdom and design of our planet and the solar system in which it exists. We can know there is a God by the things He has made (Romans 1:20) as the heavens declare His glory (Psalms 19:1).

Moon Record in the Solar System

Moon Record in the Solar SystemThe solar system record for the largest number of moons has just been taken over by Saturn. Previously Jupiter was the record holder with 79. Now the moon record in the solar system goes to Saturn with 82!

Astronomers used some of the world’s largest telescopes, including the Subaru Telescope in Hawaii to make the recent discoveries. The same team led by Scott Sheppard of the Carnegie Institution for Science in Washington, D.C., discovered 12 previously unknown moons around Jupiter last year. Now they have helped Saturn pull ahead of the competition.

Here we are living on a planet with only one Moon. Should we feel disadvantaged? Not at all! Imagine how confusing it would be to live on a planet with 82 moons. Seriously, one is enough. That is especially true when we have one Moon that is just right. We have pointed out before how precisely well-designed and well-placed our lone Moon is. Here are a few reminders with links to get more information:

Our Moon…
…has just the right mass to stabilize Earth’s rotational tilt.
…is just the right distance from Earth to create beneficial ocean tides.
…is just the right size to create total solar eclipses, which have helped us to learn more about the Sun.
…works with the Sun and stars to “mark seasons and days and years” (Genesis 1:14)
…reflects the light of the Sun to give a night light essential for many forms of life.

Those are a few of the reasons our Moon is the best one in the whole solar system! We asked before, “How many moons are enough?” Even though the number of known moons orbiting Jupiter and Saturn has changed since we asked that question, the answer is still the same. One Moon, precisely designed and positioned, is exactly what we need. We hold the moon record in the solar system for the best Moon of all! There are too many “coincidences” for it to be an accident. We see the work of a Creator, who is an amazing Engineer.

Strong Man to Run a Race

The Sun Is Strong Man to Run a Race“The heavens declare the glory of God; and the expanse shows his handiwork … Their measuring line goes out through all the earth, and their words to the end of the world. In them has he set a tabernacle for the sun which is like a bridegroom coming out of his chamber and rejoices as a strong man to run a race.” Psalms 19:1, 4-5.

The choice of Hebrew words in this psalm is impressive, and modern science has enabled us to understand why the writer compares the Sun to a strong man. The Sun has about seven billion years’ worth of fuel. That is enough to make 31 orbits of the milky way taking about 225 million years to complete each orbit. The Hebrew word for “run” used here is “ruwts,” which means “to run swiftly.” The word “race” is translated from the Hebrew word “orach,” which means “a pathway or highway.

Modern measurements show that the Sun is moving at 520,000 miles per hour (836,859 kph) around the galaxy, and the galaxy itself is moving at 1.3 million miles per hour (2,092,147 kph) through space. Not only can we marvel at the size and speed of our solar system but also at the choice of words used in the Bible to describe the creation itself. We can poetically and accurately compare our Sun to a strong man to run a race.

Ocean Treasure House

Ocean Treasure HouseOceans are essential for life on Earth. As we learn more about the oceans, we realize more and more how important the ocean treasure house is to our survival.

Fish, shrimp, and lobsters are some of the blessings that come from the oceans. Those vast bodies of water contain a great wealth of biomass that can address human food needs. The very fact that these forms of life lay millions of eggs that can provide massive amounts of food quickly is a testimony to the vast ocean treasure house. As humans conserve and farm these resources, we see the potential for food production with minimal environmental impact.

But food is only one of the blessings that come from the oceans. The oceans of the world provide water for the land. Evaporation lifts massive amounts of water from the oceans. The moisture condenses and falls on the continents providing the vital water needed by all land forms of life.

The oceans also moderate temperatures on the land. When Earth is closest to the Sun, its tilt exposes the Southern Hemisphere to the direct radiation of the Sun. Since oceans mostly cover the Southern Hemisphere, the water reflects much of the radiation, and the rest is absorbed and stored in the water. The water carries this heat toward the polar areas of the planet, moderating temperatures and allowing life to exist in abundance at the higher latitudes.

When the Earth is at its farthest distance from the Sun, the Northern Hemisphere is tilted toward the Sun, exposing the land to the Sun’s radiation. The land surface absorbs more heat radiation and reflects less of it. The waters in the Southern Hemisphere moderate the climate by using their stored energy to supplement the heat from the Sun.

In addition to their thermodynamic uses, the oceans also control the gases that are critical for life on Earth. Photosynthetic processes taking place in the oceans produce most of our oxygen. The oceans are a significant carbon sink, reducing the amount of carbon dioxide that would be in our atmosphere if the oceans did not exist. This not only restricts the adverse greenhouse effects of carbon dioxide but also recycles carbon in ways that benefit the entire planetary ecosystem.

Another ocean treasure house is the minerals they hold. The salt in the ocean is not just sodium chloride (regular table salt). The oceans contain a wide variety of elements that are critical to humans. They include iodine, magnesium, copper, and copious trace elements of biological importance. People who live far from the oceans benefit from these mineral resources because ancient oceans have deposited those minerals on land. Oceans gather and store the elements that humans need. While we have mined these ocean-deposited resources on land, we are now learning to take them directly from the ocean.

As science looks for life elsewhere in the cosmos, it is not likely that we will find it unless we find a planetary environment with oceans comparable to those on Earth. The ocean treasure house is a beautiful feature unique to planet Earth in our solar system. As science observes other stars and other systems, it becomes increasingly clear that planets like ours are exceedingly rare at best. God has provided the ocean treasure house that speaks eloquently of the Creator’s wisdom and power.

Cotyledon’s Engineered Preparation for life

Cotyledon’s Engineered Preparation for lifePlant seedlings emerging from the ground use the cotyledon’s engineered preparation for life. You may not be familiar with cotyledons, but you have undoubtedly seen them on newly emerged seedlings.

To get the idea, think about some other engineered devices that serve an essential preparatory function. When skydivers jump from a plane, they use carefully engineered equipment. The first thing they deploy to prepare for landing is a pilot chute. The pilot chute can’t land them safely on the ground. Its purpose is to deploy the main parachute. Perhaps more familiar to most people is the limited-use spare tire for automobiles. Those “donuts,” as many people call them, are not designed for high-speed driving or for driving long distances. They are engineered to get you to the nearest service station where the punctured tire can be repaired or replaced. The pilot chute and the limited-use spare tire are examples of engineered preparation.

Just as the pilot chute is packed into the jumper’s gear and the donut is packed into the vehicle, there is something packed into the seed called a cotyledon. Scientists classify flowering plants (angiosperms) as monocots or dicots depending whether they have one or two cotyledons folded into the seed. As soon as the seed has sent a taproot into the soil, it pulls in moisture and uses the hydrostatic pressure to push up a green shoot bearing the cotyledons. As those “donuts” break through the surface, they inflate to provide temporary, emergency photosynthesis. The seedling begins to drink up the water and nutrients from the taproot and use energy from sunlight to kickstart the photosynthesis process.

As the cotyledon’s engineered preparation for life gets the new plant started, real leaves begin to form. In a sense, the cotyledons have taken the plant to the first service station or deployed the main chute. Now it is ready to go from a seedling to a full-grown plant or tree. The seedling still has many challenges ahead, just as the parachutist or motorist does. But just as having the pilot chute or the donut packed and ready for deployment aids the jumper or the driver, the cotyledon supports the plant. Would anyone suggest the pilot chute or donut are merely accidents? We know those devices would not be possible without engineering design. In truth, cotyledons require far more complex engineering that only the master Designer can do.

How the Elements Were Created

How the Elements Were CreatedScience has made significant progress in understanding many things about the universe and our planet and the life on it. However, there are many, many things that we have not yet begun to understand. There are also many things we think we understand, but we are still working on better understandings. One question involves how the elements were created.

At the time of the cosmic creation event (widely called the “big bang”), there were atoms with one proton and one electron and some with twice that many. We call simplest element hydrogen, and two hydrogen atoms combine to form helium in the process of nuclear fusion. More and more fusion took place and still is happening in our Sun and other stars. The process requires intense heat and pressure to fuse the atomic nuclei into a heavier atom.

In stars much more massive than our Sun, heavier elements up to iron can are being formed by fusing more and more atoms together. When you go beyond iron, and all the way up to uranium, even the biggest, brightest, and hottest stars can’t squeeze those atoms together. Scientists believe that the heavier elements are created in exploding stars known as supernovae. When they explode, the theory goes, ripples of turbulence form as the supernovae toss their stellar material into the void of the universe. The forces in that turbulence press more and more atoms together to make the heavier elements. As those atomic elements fly off into space, gravity pulls them into lumps which eventually become planets, such as the one on which we live.

A problem with that explanation is that when the atoms are blasted from the supernovae, they are all traveling in the same direction at perhaps the same speed. How can that produce enough force and heat to fuse them together? An alternate explanation is that the explosion within the supernova is not symmetrical, creating areas of greater density. Ultradense and ultrahot regions concentrated in small areas of the exploding mass perhaps give a better explanation of how the elements were created. (See a paper on that published in the Proceedings of the National Academy of Sciences of the United States.)

Carbon is the basic building block of all living cells. Nitrogen and oxygen, which are the next steps above carbon, bond with it along with other atoms to form living molecules. A little higher on the atomic scale are sodium, magnesium, phosphorus, and other elements which are essential to life. Iron, nickel, copper, and other metals are in molecules within our bodies, and we use them in pure form to build our homes, cars, and electronics. The heavier radioactive elements such as uranium deep within the Earth generate the heat that creates a molten iron core that generates a magnetic field which surrounds and protects us. This is a very simple explanation of a very complex system that makes it possible for us to be here.

Science is only beginning to understand how the elements were created and how they are continuing to be created. How did this amazing, complex system come into being with the precision that put life on this planet? We could declare a god-of-the-gaps to say that we don’t understand it and therefore, God did it. It is much better for us to learn HOW God did it. As we begin to see the wisdom required to put this incredibly complex universe together, we become more in awe of the Creator. We don’t have a god-of-the-gaps who “zaps” things into existence like a magician. Our God is an engineer craftsman who creates complexity and beauty that leaves us without excuse. (See Romans 1:20.)

Solar Cell Christians

Solar Cell Christians Depend on the SonAren’t solar cells wonderful? We have lights along our sidewalk that allow visitors to reach our front door without stepping on a toad or disturbing our resident garter snake. Those lights are powered by solar cells, and as long as we have a few hours of sunlight, they function beautifully. Unlike regular batteries, these solar cells have an essentially endless life. The design of the solar cell allows rejuvenation as long as it stays in touch with the Sun on a regular basis. This brings to mind the idea of solar cell Christians.

I would suggest that God’s plan for His children is not for us to try to exist on our own. In Genesis 3:8-10, we see Adam hearing “the voice of the Lord God walking in the garden.” How does a voice walk? In verse 10, Adam says he heard God’s voice and in verse 17 he listened to the voice of his wife. In John 1:1, we are told, “In the beginning was the Word” (Greek logos). In verse 14, the “logos” was made flesh and dwelt among us. In Acts 2:38-39, all Christians are promised that they will receive “the gift of the Holy Spirit.”

This whole concept is not that mysterious if we reflect on the solar cell. How do we find the strength to live the kind of life that God calls us to live? How do we give to others and support people in trying times? Like the solar cell, if we try to do it without continuing reconnection to the ultimate source of energy and power, we will become dim and eventually lifeless. Jesus calls Christians to be “the light of the world” (Matthew 5:14). Without the rejuvenation of God’s Son within us, we can start to look more and more like the darkness of the world that surrounds us.

Our worship, our Bible study, our fellowship with other Christians, and our prayers are all a part of our spiritual recharging. The voice of God walks within us as we use God’s Word. We dare not depend on our own wisdom to remain the light of the world as we face enormous challenges. A solar cell needs constant contact with the Sun, and we need continuous contact with the Son. The analogy of solar cell Christians reminds us that God’s Spirit gives us the power to be far more than we could be on our own.

Does God Exist? and Is the Bible True?

Does God Exist? and Is the Bible True?
How can we investigate the questions, “Does God exist?” and “Is the Bible true?” Many go to an atheist website or read a book by an atheist to decide. A vast majority of people who attack our position on the Bible follow atheist websites. The problem here should be obvious. If a person’s religious view is that there is no God, then obviously, the Bible cannot be the word of God since God does not exist! If you tell anyone something often enough and long enough, eventually they will believe it.

The same kind of problem could come up in the opposite way if one were to read only a book on the truth of the Bible written by a Christian minister. We are not saying that you should not read books written by atheists or ministers. What we are saying is that you cannot stop there and be satisfied whether the Bible is true or false. To answer the questions like “Does God exist?” and “Is the Bible true?” by reading what people say, you need to read both viewpoints. You also have to learn how both sides answer the questions posed by people whose views conflict with theirs.

A more direct way to answer the question “Is the Bible true?” would be to explore the evidence yourself. Is the Bible accurate in its statements of a scientific nature? Are the principles of psychology used in the Bible practical and worthwhile? Is the Bible’s approach to human relations valid? Can following the principles of the Bible bring peace, harmony, unity, and positive things to human beings? The way to answer these questions is to read the teachings of Jesus and ask yourself about these issues. It can be helpful to listen to the objections of an atheist and listen to a Christian apologist respond to those objections. But, take the time to look at the evidence and ask questions yourself. Starting with the Sermon on the Mount in Matthew 5-7 will show you clearly the answers to many of those questions.

Another approach worth considering is the cosmological evidence. The argument we make is very simple. We ask three questions: Was there, or was there not a beginning to the cosmos? If there was a beginning, was it caused, or was it not caused? If it was caused, what or who caused it?

The evidence for each of the steps in this logical discussion about origins comes from a variety of sources. In the first question, we can look at evidence from cosmology. The fact that the cosmos is expanding, strongly suggests that the expansion had a specific point in space and time from which it started. Any astronomy textbook will point this out. There is chemical evidence in the cosmos in terms of hydrogen, the fuel that powers the cosmos. If the universe had always existed, there would be no hydrogen left because it is the element from which all other materials are made. The power of the Sun and stars comes from the fusion of hydrogen atoms. We also see evidence from physics in the form of the laws of thermodynamics. We know that, in closed systems, things tend to move toward a condition of disorder. If the cosmos had always been, it would be totally disordered because the cosmos is a closed system with no energy being added to it.

The point we are making is that evidence comes from different fields. Experts in the fields of cosmology, physics, and chemistry have written about these processes. The evidence gives predictability to the cosmos and has many practical uses in space travel and astronomy. There is a wide range of support from a variety of areas for the argument that the cosmos had a beginning, that it was caused, and that it was intelligently caused.

Being confident about your beliefs cannot be rooted in what someone else tells you or what is popular. There are always problems with any biased belief systems passed on to you by others. You should be open to new evidence even when you have formed an opinion about something. The lesson of history on matters related to faith is that new discoveries support and confirm faith in God and His word.

We do not have to be consumed by doubt and paralyzed by uncertainty. The Bible speaks confidently, and we must work to build a dynamic faith that allows us to meet the needs that we were put here to address. The questions, “Does God exist?” and “Is the Bible true?” are probably the most important questions you will ever ask. Do the research and think!
