Global warming is the warming of the earth. The Earth’s average temperature is slowly rising, causing shorter and milder winter seasons in various countries around the world.
There are many gases in the Earth’s atmosphere, but many are natural and harmless. CO2, however, is not healthy for the atmosphere. CO2 remains in the atmosphere longer than other gases. Even a slight increase in CO2 in the atmosphere can cause significant increases in global temperatures. Most CO2 emissions come from the burning of fossil fuels. Cars and other vehicles can produce up to 1.5 billion tons of CO2 annually, and coal-burning power plants can produce 2.5 billion tons. The United States is responsible for a great deal of these emissions. And though the U.S. is doing their best to decrise this problem by lowering their emissions, other countries are doing the opposite.
So what affect does global warming actually have on the environment and on the human? Does an increase in temperature of less than a degree actually change the earth? The answer is: yes. Global warming has been linked to the increase in wildfires and floods. It has been seen as the cause of rising sea levels and stronger hurricanes. The Arctic’s polar ice caps are melting at a rate of 9% every decade. Animals are losing their habitats and may end up extinct and what do you think all the watter goes to?
There are solutions to global warming. Scientists and governments are working together to create alternatives in the live of humans. People don’t have to give up their vehicles, but they may decide to choose hybrid cars. Wind turbines and other sources of renewable energy can prevent the burning of coal, which has a major inpact on CO2 emissions.
