Colors of Fall and What they Mean

Colors of Fall and What they Mean

The beauty of autumn’s brilliant colors is an amazing testimony to the creative wisdom of God as well as an expression of His love of beauty. The colors of fall are caused by several pigments and the interaction of sunlight and sugar.

Most of us know that chlorophyll makes leaves green. When leaves receive reduced sunlight in the fall, they also have a reduced supply of nutrients and water, causing the chlorophyll to be removed. The chlorophyll masks two pigments that have different colors. Carotene is yellow, and several varieties of anthocyanins are red. Many leaves contain tannin, which is brown and is dominant in oak trees. Sunlight acting on trapped sugar also produces anthocyanins with various sparkling colors, which is why the color is so spectacular on a sunny autumn day in a maple forest.

As the days grow shorter, the reduced amount of sunlight causes a corky wall called the “abscission layer” to form between the twig and the leaf stalk. This wall will eventually break and cause the leaf to drop off in the breeze. The corky material seals off the vessels that supplied the leaf with nutrients and water and blocks any loss of sugars from the plant.

What is especially interesting is that the leaf colors are not all the same. Some vines produce spectacular colors. Poison ivy takes on a beautiful red due to a high concentration of anthocyanin. Aspen has a high concentration of carotene producing the vivid yellows which dominate the woods in the Rocky Mountains. In Michigan, we have maples, gum, aspen, and oak, giving us spectacular colors that vary from one location to another.

The colors of fall are a great testimony to the fact that God paid attention to aesthetics in the creation. If survival of the fittest were the only criteria for choosing the chemicals that allow plants to survive, it seems that there would be one best choice. Different chemicals provide a vivid, beautiful splash of color for humans to enjoy. Beauty is not part of the evolutionary model, but it speaks of God’s creativity, giving us a wonderful and beautiful world in which to live.

Winter Is Coming

Beautiful Fall but Winter Is ComingFall is a beautiful time of year. We all enjoy the changing colors of the trees, and there are changes in our lives that involve preparation for winter. Not all of us view these changes in a positive way. The fact is that whether we like it or not, change is coming. The sight of trees turning colors and the leaves falling to the ground reminds us that winter is coming.

Life is very similar to that. As we get older, signs are telling us that major change is coming in our lives. Our hair turns gray or falls out or both. There is pain in our movements that was not there before. The way we gain weight and our energy levels change, whether we like it or not. All of the medication in the world will not stop the physical changes coming in our lives. Mentally and emotionally, we must adjust to the fact that our faculties are not functioning as they did in the past, and we experience the loss of friends and family making us aware of our own mortality.

One of the things that belief in God does to us is that it allows us to approach the changes that come to our lives in the same way we do the colors of fall. We can scream and fight the fact that winter is coming, but it will still happen. We can buy cosmetics and vitamin pills, but the winter of life comes anyway. When I was an atheist, I had to look at life with all of its problems, pain, struggles, and the awful things that happen as the very best that I was ever going to have. Now, as a Christian, I can look at life with all of its beauty, wonder, and the fantastic things we all enjoy as the absolute worst I am ever going to have to endure.

How do you look at life? Is it the best you will ever have or the worst you will ever have to tolerate? Can you not see that this is the difference between the believer and the nonbeliever. It’s as different as night and day, black and white. If there were no other reason to believe in God but this one, it would be a compelling reason.

We can debate and fuss about things we do not understand. We can complain that we do not like the way God does things. But the fact is that all of those arguments have very little meaning when we are looking death in the face. The colors of change in the fall tell us winter is coming, and the colors of life tell us we will all soon stand before our Creator in judgment. Know why you believe what you believe, and intelligently trust in God to guide you to eternity.

Autumn Equinox and Season Design

Autumn Equinox and Season Design
We have just passed the autumn equinox and what we call “the first day of fall.” It will be late December before fall officially ends at the winter solstice. On the first day of fall here in Michigan, it was unseasonably hot, and people were griping about “where is the cool fall weather we are supposed to have?” Long before the first day of winter on December 20-21, we will have snow. Is there something wrong with the seasons, or is the trouble with our understanding?

“Equinox” suggests that the length of the day is equal to the length of the night. The Sun is overhead at the equator, and from now until December 20 it will be directly overhead at progressively greater southern latitudes until it reaches just past 23 degrees south latitude. Here in the north, the Sun’s elevation above the horizon will get progressively lower, meaning that less and less of the Sun’s energy will strike the Earth’s surface so the weather will get cooler.

The problem with this simple picture is that there is a lag in the seasons. During the summer months in the Northern Hemisphere the lakes and oceans warm from the sunshine. Water has a high specific heat, so that heat is stored and is released slowly. That means we stay warm longer than expected in the fall. In the Southern Hemisphere the picture is complicated by the fact that the Earth is closer to the Sun during their summertime, so the radiation is more intense. That might be a problem except that the Southern Hemisphere has more water than the Northern Hemisphere because oceans cover more of the southern Earth’s surface. With that greater storage and absorption capacity moderates the temperatures in the Southern Hemisphere.

The autumn equinox reminds us of the incredibly well-designed system of the Earth. It is easy to over-simplify the seasons and the equinoxes and solstices, but the system functions remarkably well. Without that careful design, the weather picture would be far more unstable than it is. Proverbs 8:22-31 speaks of wisdom’s involvement in all of the creation. We are just now beginning to understand how the system works and how our use of Earth’s resources affect the system.
