GLOBAL WARMING:
a Matter of Global Responsibility
In recent years, a crucial environmental problem has been an object of study among climate scientists: global warming.Our planet is surrounded by an atmosphere and this mixture of gases includes carbon dioxide (CO2). For thousands of years CO2 , and other gases have trapped solar heat in the atmosphere, keeping our planet temperature at around 15º Celsius. As a result, Earth has been habitable. However, by burning coal, gas and oil and by clearing forests, we have increased the amount of CO2, in our planet’s atmosphere. According to climate scientists, the levels of CO2, have risen by around 30 percent in the last 200 years. The increase of CO2 has warmed Earth’s atmosphere. The global average temperature is now about 0.6ºC higher than it was one hundred years ago. This change is called global warming.
