Effects of global warming
Global warming can bring many long-lasting and devastating consequences to Earth and all its occupants. It is a well-known fact that global warming is real and is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO₂), methane and other greenhouse gases into the atmosphere.

One of the most noticeable effect of global warming is ice around the Earth is melting, especially at the Earth’s poles. These ice includes ice sheets covering West Antarctica and Greenland, Artic sea ice and mountain glaciers. In the year 2012, scientist saw the smallest amount of Artic ice cover in the Artic Sea. Analyst project that the Artic sea will be completely free of ice in a matter of years.

Another prominent effect of global warming is the rising sea level. Sea level rise became faster over the last century that is caused by melting polar ice in the Arctic and Antarctic region, coupled with melting ice sheets and glaciers across Greenland, North America, South America, Europe and Asia. Since year 1870, the global sea level has risen about 8 inches. If the sea level continues to rise, many coastal areas and low laying ground will be flooded and those places can’t be populated by humans.

Fossil fuels such as petrol, methane and propane contain mostly carbon. When these fuels are burned, they react with oxygen and produce carbon dioxide. Because of our heavy use of fossil fuels, the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution. The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide. The level of carbon dioxide, (CO₂) in the atmosphere increases, ocean acidification occurs as the oceans absorb some of that CO2, which increases the acidity of seawater. Since the Industrial Revolution began in the early 1700s, the acidity of the oceans has increased about 25 percent, according to the EPA (Environment...
