As you read this, another snow cover in the Northern hemisphere melts. As you amuse yourself updating your Facebook account, sea level increases. And as you watch your favorite television show, the hole on the ozone layer is becoming large.
Ice melting, sea level increase and ozone layer depletion are just some of the effects of global warming, a global phenomenon that our world is facing today.
Global warming is the increase in the average temperature of Earth’s near-surface air and oceans since the mid-20th century.
For the past years, various human activities have caused this global phenomenon. Some of these activities are riding smoke-belching vehicles, burning of coals, deforestation and usage of household appliances that are not environment friendly. These activities emit greenhouse gases, like carbon dioxide, chlorofluorocarbons, methane and nitrous oxide, which are extremely harmful to the nature. In other words, every time we ride buses, burn our wastes and use air conditioning units, we add to the concentration of greenhouse gases in the atmosphere.
These are just some of the many causes of global warming. What are then the effects of these human activities that caused global warming?
Ice is melting worldwide. Mountain glaciers, ice sheets covering West Antarctica and Greenland and Arctic sea ice are all melting. These melting results to sea level rise. The increase of the sea level became faster and faster over the last century. Sea level is expected to rise between 7 and 23 inches by the end of the century. Sea level increase will result to tsunamis and island sink. Hurricanes and other storms are also an effect of global warming. Many strong storms had hit the Philippines for the past years and all of these storms devastated the lives of the Filipinos.
Aren’t you alarmed by these? What can you do to save the Mother Earth?
Back to basic: reduce, reuse and recycle. These three simple ways can be a big leap in combating global warming. Try to avoid the use of household appliances that emit CFC’s. Also, try to avoid riding buses. Instead, try to walk or use the bicycle. This does not only help in lessening the concentration of greenhouse gases in the atmosphere, it also helps to improve your health.
Global warming is indeed a warning so we better act now.
