Climate change: We need to act now or never.

Over the last century, we, human beings, have irrevocably damaged the environment through the unscrupulous greed of big business and our own willful ignorance. Climate change is defined as a significant and permanent change in the weather patterns and is often used to describe the human-caused impacts.  It is estimated that the Earth’s surface temperature has raised by 0.6^o ± 0.2 ^oC over the last century. The decline in Arctic ice is an example of the global warming. It caused the sea levels around the world rising. According to its World Energy Outlook 2009, the International Energy Agency (IEA) stated that the world is on a path for a risen in global temperature of up to 6^o C, with catastrophic consequences. Sea level rising can displace many seaside communities. For example, a sea level rise of 200 mm can make  700,000 people in Nigeria homeless.  It is estimated that to avoid severe weather and sea level rise and to limit the temperature increase by 2 ^oC, the Green House Gases concentration needs to be stabilized at 450 ppm CO2e. To do that, global emissions has to be halved by 2050. In 2009 IEA Reference Scenario, global energy-related CO2 emissions rise from 29 Gt in 2007 to 40Gt in 2030. 75% of the increase is associated with the developing economics of China, India, Middle East… As the world's need for energy grows, we need to focus on develop clean fuel initiatives to make the most of the fossils fuels and create sustainable energy sources from diverse renewable energy.
