Washington DC -Autumn has begun in the United States. But perhaps for the first time in centuries, autumn is in full swing.The leaves are turning yellow from the trees.This time, nature did not scatter on them the colors that make the eyes love and the soul happy.This time autumn is sad and miserable.
For many, it may be interesting to note that in many parts of the United States, autumn is even more fascinating than spring.In the spring season the colors come on the flowers, but in the autumn it is as if the whole atmosphere is covered with colors.
In the fall, most Americans go out for long drives or head to national parks and natural forests to enjoy the beauty of nature.This period of silver and yellow is very short and usually lasts for two to three weeks.
At the end of October, strong cold winds begin to blow and the leaves begin to fall off the branches of the trees.Then in November, the trees turn pale and the ground is filled with yellow dry leaves and the onset of winter begins.
Autumn Colors in United States
These autumn colors are not limited to the United States, but in many countries and regions of the world.Where the weather and ground conditions are similar here, these colors show their spring on the trees in autumn.But in deserts, plains and areas where the heat is high and the weather is mostly dry, in autumn the leaves suddenly turn yellow and fall from the branches of trees.
Scientists say that the change in the color of the leaves in autumn, or the change from green to yellow in the branches, is directly related to the temperature and length of the day.If the temperature is high, the leaves fall off quickly and if stormy winds blow, the twigs break off with the leaves.
In many parts of the United States,
why do many leaves change color before they turn yellow in the fall?
This story is also very interesting.
Simply put, the leaves combine with sunlight to form a special compound, chlorophyll, that makes them look green.But it depends on the length of the day and the temperature.In September, the duration of the day decreases and the weather starts getting colder.Which affects the process of chlorophyll in the leaves and causes its cells to break down.
These cells appear in three colors: red, orange and yellow.
This is because each leaf undergoes a different process that produces different shades of these colors.
Global Warming
Due to global warming, most of the leaves are dying and breaking instead of changing color.
Due to global warming, most of the leaves are dying and breaking instead of changing color.
But since the beginning of October this year, most of the leaves are still green, or in some places completely yellow.This is almost the same scene that is usually seen in deserts or plains. This is because of global warming.
This year has been extremely hot across the United States and new temperature records have been set.Temperatures were much higher than normal in September.Which did not provide a natural signal to slow down the process of chlorophyll formation in the leaves. And their color has not changed.
The leaves have a certain age. After reaching this age, the leaf loses contact with its branch and is blown away by a gust of wind.In the United States, the process begins around mid-October.
The colors of the leaves in autumn offer a charming sight.
The US states of Maine, Denver and New York are especially notable for the colorful scenery in the fall.But Michael Sunberg, a Denver-based botanist, said 70 percent of the leaves had not changed color by the end of September when the leaves began to fall.He said that instead of the leaves gradually changing.Their color would change and they would dry up and fall off, now they are falling from green to dry without any middle ground.This is due to the temperature.
Paul Sheiberg, a tree scientist at the Vermont Department of Forests, says the warmer temperatures in the area have left the leaves green for longer and the temperature has stopped them from changing color, so we need autumn.Colors are not visible.
Global Warming Effects
The effects of global warming are being felt not only in the colors of autumn but across the globe and are intensifying with each passing year.Many fertile areas are turning into deserts. Strong storms are coming somewhere.Rains and floods are wreaking havoc elsewhere.
Due to the high temperature in September, the leaves of the trees are turning yellow.
Due to the high temperature in September, the leaves of the trees are turning yellow.
Rising global temperatures are not only taking away the colors of autumn, but also putting many species of life on the planet at stake.
A recent report states that at least 23 species of birds and other animals, including the beautiful bird Hudhud, have become extinct in recent decades.
Experts say that if immediate and concrete steps are not taken to stop the rising temperature of the earth.It is very possible that it will be difficult for human beings to live here in the next century.

"If we want to preserve the beauty of our planet and protect the planet from warming, we must value our forests," said Andy Fenton, a wildlife conservationist at the Massachusetts Department of Forests.Because forests provide us with everything we need to survive, clean air, clean water, clean forests, mild weather and especially beautiful autumn, in which we want to see color.
