Dire predictions about the end of the world as we know it usually accompany any discussion on global warming, but what does global warming really entail. Is it really the bad? Science has spoken and the answer is a resounding yes. Global warming now stands as our planet's most pressing problem, and many are even using the world crisis to discuss the problem that now afflicts all life on planet Earth. What causes global warming? The most basic cause of global warming has to do with the ability of the Earth to deal with so-called greenhouse gases. On this planet, the earth's atmosphere sustains a natural supply of these so-called greenhouse gases. The natural greenhouse gases work by capturing the heat emitted from the Earth—just enough to warm the surface of the planet and keep it warm enough for life to be able to thrive on the planet. Without the effect of these greenhouse gases, the earth would be too cold to sustain life on it. The problem with greenhouse gases is that now there are simply too many greenhouse gases, mostly in the form of carbon dioxide, being released into the atmosphere. This process began after the Industrial Revolution in the mid-1700s, when human industry began creating large amounts of greenhouse gasses into the atmosphere. This occurred when fossil fuels began to be burned to run factories, supply energy for cars, trucks, planes, and to run power plants. It is estimated that most of these greenhouse gases can stay in the Earth's atmosphere for fifty years and longer. In short, since the industrial revolution, human activity has produced more greenhouse gases than the Earth is capable of removing. Imagine that the natural layer of greenhouse gases is wrapped around the Earth like a thin sheet that keeps the Earth just warm enough to sustain life. Now imagine an extra thick blanket surrounding life—that is what too many greenhouse gases have done to the Earth. The release of so many extra greenhouse gases into the Earth's atmosphere has causes the Earth to warm by about one degree during the past century. This may not sound like much, but scientists have proved that the rate at which the Earth is heating up increasing. Even though one degree may not sound like too much, the truth is that even slight variations in temperature can have very strong consequences. One degree can make all the difference in preserving our way of life on this planet. Studies have shown that even a slight change in the level of carbon dioxide can be very consequential to Earth's survival. So what is next? Researchers expect that if we don't do anything to help solve the crisis of global warming, it is estimated that the global average temperature will increase by two degrees Fahrenheit to over eleven degrees Fahrenheit by the year 2100. Even if the change in temperature is not as drastic as expected, it is still predicted that many major natural catastrophes will result. What are some of the major natural catastrophes that can befall planet Earth if the Earth's global temperature continues to rise? Climate change researchers believe that rising global temperatures will result in greater natural disasters, including more frequent and turbulent hurricanes, rising sea levels, serious droughts, and severe land erosion. There is only way to stop the current climate crisis and that is to drastically cut the amount of greenhouse gases that are being released into the Earth's atmosphere. This can only be done with worldwide cooperation and a commitment by all the world's most prominent governments. Every person can also make a small difference in their own daily life by reducing their own use of greenhouse gases.
