Causes and Effects of Global Warming

Today, based on the topic environment, I am going to discuss on the cause and effect of global warming that is happening on our mother earth. What is global warming? Global warming is the term used to describe the gradual increase of the average temperature on the Earth’s atmosphere and the oceans, which is believed to cause climate change on earth permanently. Based on scientific research on climate change due to global warming, the average temperature rise is between 0.4 to 0.8°C for the past 100 years. Scientists also predicted that the average temperature could increase between 1.4 to 5.8°C by the year 2100.

Greenhouse gases can cause global warming. Based on Collins Dictionary, The greenhouse effect is the problem caused by increased quantities of gases such as carbon dioxide in the air. These gases trap the heat from the sun, and cause a gradual rise in the temperature of the Earth's atmosphere. Gases such as carbon dioxide, sulphur dioxide, methane, nitrous oxide, halocarbons and so on, built up in the atmosphere due to increased use of energy and the expansion of global economy in the 20th century. All these gases alters the radiative balance of the atmospheres whereby these gases absorbs the heat from

Warming can force animal species to move to higher latitudes in order to survive where the temperature are more condusive. As for sea level rise, salt water will flow into freshwater system are causes death of some species, thus removing removing these species from the existing food chain. Global warming changes the timing of seasonal life such as the migration of bird species and butterfly species and the blooming of flowers. With climate change due to global warming, many species are facing extinction. All these species are particularly climate sensitive especially those animals that are adapted to mountain environment, sea-ice habitat like ringed seals, and cold-water fish such as
