Over the carbon dioxide, methane, nitrous gas.

Over the 50 years, the global temperature has increased at the fastest rate in recorded history. Climate change has argued that has been a slowdown in rising global temperature, but several recent studies have disagreed with this claim. Global temperature will keep increasing to an inconceivable situation and in the future, our earth may become uninhabitable.So what caused the global warming? Global warming can cause by fume that released by factories, vehicles, or burning of fossil fuels.

These may increase the greenhouse gases into the atmosphere. The greenhouse gases include the carbon dioxide, methane, nitrous gas. When these gases go into the atmosphere, they trap the heat from the sun and raise the temperature of the earth.

These greenhouses gases may remain in the atmosphere for many hundreds of years.If we don’t relieve or aware this global issue, it will bring a lot of serious consequences in the future. Frist, there may not have enough food supply. The crop productivity will decrease because of the impact of climate change.

According to the experts, at least half a million people will die in the year 2050 as a result of starvation. Second, ice sheet such as Greenland and Antarctica will all melt and become extra water that causes the rising of sea level and flooding the coastal region. Third, global warming will directly affect human’s physical health. As the high temperature allows the ozone particle in smog to grow rapidly. Exposure to high level of smog can cause health problems such as asthma, heart disease, and lung cancer.

Scientists expect the temperature will continue rising somewhere between 2 to 11.5 degrees in the next 100 years. You may think it is a small number. But the rate of that increase is doubled over the past 50 years. So what can we do to relieve global warming? We can work to replace fossil fuel with the renewable energy resource such as solar or wind, and another way to reduce power like carpooling, recycling, shopping in local as well as switching the energy-efficient light bulbs. However, permanent change may require a national movement.

The government should make a law of limiting the emission of greenhouse gases.To get rid of global warming, everyone should take their responsibility to reduce the greenhouse gases. Let us make our planet become nice and comfortable to live.
