Many people feel that the world is slowly changing due to global warming. So what is global warming? Global warming is the increase in the average temperature of Earth's atmosphere. The major causes of global warming are the greenhouse gasses and human pollution. Greenhouse gasses and human pollution can lead to many effects of global warming like sea levels rise and diseases spread faster, but we can stop global warming by doing small changes in our daily lives to help the Earth. Global warming is caused mostly by our pollution which makes the atmosphere warmer.
The Description of Global Warming
What exactlly is global warming? Global Warming is the increase in the average temperature of Earth's atmosphere. The thick atmosphere traps the sun's heat and warms the Earth. Global warming started occuring in the 1800's, and since then the temperature has increased about 0.5 degrees F to 1.5 degrees F higher. Over the past 50 years, the global temperature has had the fastest rate of increase, and the Earth has also warmed 1 degree F over the past 100 years. The temperature of Earth's surface now is about 59 degrees F. Scientists have hypothesised that the Earth's atmosphere will be about 2 degrees F to 4 degrees F higher by the year 2100. Today, Americans produce 25% of the greenhouse gasses (the U.S. has the highest rate of pollution). The greenhouse gasses are water vapor, carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, and chlorofluorocans (CFCs). These greenhouse gasses are a huge problem because they are the leading cause of global warming.
What is Causing Global Warming?
There are so many causes of global warming, but the main cause of global warming are the greenhouse gasses which are all natural gasses. Carbon dioxide, a greenhouse gas, is the major greenhouse gas. When greenhouse gasses are released into the air they get trapped in the atmosphere. The use of fossil fuels, such as coal, for energy produces pollution. Cutting down trees is another major cause of global warming because the less plants there are the more carbon dioxide there is in the air which is a greenhouse gas. Other causes of global warming are the power plants, automoblie exaust, factory smokestacks, and animal waste. To conclude this, most of the causes of global warming are caused by human activities.
What Could Happen if Global Warming gets Worse?
There are so many effects of global warming that can harm us and many other creatures. For example, sea levels could rise, there could be major impacts on agriculture, weather changes, and spread of diseases. Also, there maight be a major temperature increase. Droughts, dust storms, wildfires, floods, and short winters will be very common and increase hunger and malnutrition. When lakes and rivers start drying up, glaciers and sea ice melt,loss of wetlands, and water evaporation is common there will be less water for drinking, taking showers, and pools to go swimming in. Also, seawater and freshwater could mix together, and coastal cities and small islands could submerge. Before we know it, there will be more strong hurricanes, tornadoes, and storms. Many animals can be harmed or can become extinct because of the heat (or warmer ocean waters) and the rapid changes. This could also force animals to move out of their habitats or disrupt their habitats. There are many diseases right now and the last thing we need is a new diseases to spread. Although, one of the ways that global warming can be good is that it could reduce deaths from coldness, but the heat waves could cause deaths and illnesses though. There are so many effects of global warming, but we could stop these things from happening by doing small simple changes in our lives.
What Can We Do to Help the Earth?
To help our Earth, we should start making changes in our daily routines. For example, everyone can recycle cans, bottles, jars, magazines, plastic bags, and newspapers. When you go shopping for a new refrigerator, washer, or dryer, buy one that doesn't use much energy. Also, (if you don't have a car yet) ask your parents to buy a car that doesn't pollute much and ride your bike or walk to short distance places. You can plant trees because they absorb carbon dioxide, a greenhouse gas, that is a major cause of global warming. Some countries are starting to use wave power, wind power, and solar energy. Wind power is a great energy source because it is clean, continuous, and cheap - the type of energy we need. Other little things you can do are carpool with friends, ride the bus to school or work, use less water, and use less electricity. In conclusion, small changes made in daily lives can produce grand results towards helping the environment.
Global warming is mostly caused by our pollution making the Earth's atmosphere warmer and warmer. When we burn fossil fuels, the pollution of it is usually turned into greenhouse gasses which are the main cause of global warming. So what is global warming? Global warming is the increase in the average temperature of Earth's atmosphere. Gobal warming is a major problem and we should start making changes in our lives to help stop global warming!
