As we know that our earth is hotter now than previous. The hot temperature becomes a problem that affects our daily life. The hot temperature is one of the effects that caused by the global warming. What is Global Warming? Global Warming is the change or the increase of the earth temperature both of water and land and also the atmosphere. In 100 years, the temperature of the earth has risen approximately 0.75 degree Celsius. If we compare the temperature of the earth in 1940-1980 and in 1995-now, the average temperature is much different. Before we continue to discuss more about the global warming, I want to explain about the difference between global warming and climate change. Sometimes there is a misunderstanding between global warming and climate change. Most people think that the global warming and climate change is same, but they are DIFFERENT. Global warming is the change of the temperature of the earth, while the climate change is the change of the climate that caused by the global warming. So the climate change and global warming are different but they still have a relation.
The global warming can not appear by itself without a cause. There are some of the causes that caused the global warming. There are two causes, first is natural causes and second is a manmade cause. The natural causes are the methane gas, volcano eruption who produce CO2, and the greenhouse effect. The greenhouse effect is one of the biggest cause that caused the global warming. The greenhouse effect is a process that can make the earth warms. The greenhouse effect gases include methane, CO2, H2O, etc. When the sunlight is entering the earth, it will be reflected back and the other sunlight is absorbed by the gas of the greenhouse effect. And it makes our earth warmth for the sustain life. If there are a lot of greenhouse gases, it will absorb a lot of sunlight too and it can make our earth hotter and hotter. The manmade causes are the cause that comes from the human behavior. The manmade causes are the burning of fossils fuels, the use of air conditioner, and deforestation. The burning of fossils fuels also affected the greenhouse effect. The burning of fossils fuels can increase the greenhouse effect gases in the atmosphere and it makes the earth become hotter.
The global warming also has an effect for the earth and human in daily life. There is some effect that caused by the global warming. First is the global warming increase the sea level because the global warming makes the ice melt and it makes the level of the sea increases. Second, the global warming is changing the water sedimentation and pattern of the weather that can cause a drought and flood. Third, for the agrarian region the global warming effect the farm like when the farmers should plant crops because the weather changes irregularly. After that, the global warming increase the average of temperature that makes the earth hotter. The climate changes whose one of the effect of global warming can directly affect human physical health. The global warming also affects many species of plant and animal.
There is some evidence that shows how global warming is taking place. The portage glacier in Alaska is one of the evidence. In 1914, the glacier still covers most of the surface but in 2004 the glacier has melted and become a river on that surface. The second evidence is Colorado river in Arizona. In June 2002, the volume of the water still in normal condition but in December 2003 the volume has decreased until one-fourth of the previous volume.
The global warming is still happening until now and soon. We do not have much time left. We have to keep the earth temperature stable for sustain life. There is a possibility if the global warming is continuing, the temperature of our earth will reach Venus temperature. Venus temperature is 462 degrees Celsius which make it impossible to live there. Stephen Hawking predicts if our earth will become a fireball by 2600 because of the global warming. So let us stop the global warming from now. Let us believe that we can stop the global warming. There are simple things that we can do from now and start it from our self. First, turn off our computer or TV or the other electronic stuff if we do not use it to reduce the electrical energy used. Second, take a shorter shower to conserve the water because there is a possibility that water will lose in the future because of the global warming. Third, let us reduce to use air conditioner by close the curtains and keep the room cool. As we know that air conditioner contains a greenhouse effect gas that can cause a global warming. After that, let us reduce the emission and the burning of fossils fuels by using an environmentally friendly transportation like a bicycle. Go green by reforestation, reuse, reduce, and recycle also some way that we can do to stop the global warming. The last thing is powering our house with renewable energy. From now, let us start from our self to stop the global warming. Save the earth, save our lives, and save our descendant life.
