GLOBAL WARMING : CAUSES AND EFFECTS

Global warming, it’s a typical global phenomena that has been peoples concern for years. Global Warming is caused by many things. The causes are split up into two groups, man-made causes, and natural causes. Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. When fossil fuels are burned they give off a green house gas called CO2. Another major man-made cause of Global Warming is population. More people means more food, more methods of transportation, and that means more methane because there will be more burning of fossil fuels, and more agriculture. While natural causes are the causes that were created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas that traps heat in the earth's atmosphere.

In the other side, there are many great effects of global warming. Increase of temperature on the earth is one of the global warming effects. Increasing global temperatures are causing a broad range of changes. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Changes in temperature also change precipitation patterns that will increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes. Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.

Based on the explanation above, we’ve known about the effects of global warming. Therefore, as the young generation we must try to decrease the effects from the least thing that we can do. For example, we can minimize the use of air conditioner, perfume, and many other things that using fossil fuels. So, let’s start to save the earth from now on!
