Global warming is a conqueror we must not kneel to but rise to. Global warming has increased since the 20th century due to industrial revolution. It leads to catastrophic events like climatic changes, warmer temperatures, and rising sea levels. The carbon dioxide level in the climate today is greater than at any point in the most recent 800,000 years (Kunzig 2013). These are only signs of the worst to come in the future. Humans have not been making any changes to their lifestyles, political systems have been handicapped in the face of this issue, and the impact of global warming has been increasing year after year. The world needs to address global warming more seriously because of drastic temperature changes, rising sea levels, and more frequent and severe natural disasters like floods.
The inhabitants of Earth have been selfish, and have been burning fossil fuels for their own needs without thinking about our planet or the future generations. These activities have substantially increased the concentration of gases like carbon dioxide, nitrous oxide, and methane in the earth's atmosphere. Scientist believe that these gases, also known as greenhouse gases, trap the radiation by the earth's surface and direct it back into the lower atmosphere. This effect, called greenhouse effect, causes an increase in the temperature of the earth's surface and the phenomenon is called the global warming.
The issue of global warming needs to be addressed because the temperature on the earth's surface is increasing at an alarming rate. A study by NASA's Goddard institute of space studies shows that the average global temperature has increased by 1.4 degrees Fahrenheit in the previous ten years. The Intergovernmental panel on climate change (IPCC) published that the last 11 years have been the warmest among the 12 warmest since 1850 ("Global Warming Fast Facts"). The six-marker SRES scenario has projected a global increase in surface temperature for the year 2100 to be in the range of 2-4 degree Celsius (Anderson 2012).
