Global Warming
Global warming occurs when carbon dioxide and other air pollutants collects in the atmosphere and absorb sunlight and solar radiation that have bounced of the earth surface.The heat trapping pollutants especially carbon dioxide,methane ,water vapour and synthetic fluorinated gases also known as the green house gases and their impact is called the greenhouse effect. Though natural cycles and fluctuations have caused the climate to change several times over the last years. Our current era of global Warming is directly contributed to human activity specially to burning of fossil fuel such as coal oil gasoline and natural gas which results to greenhouse effect. Curbing dangerous climate change requires very deep cut in emissions as well as use of alternative to fossils fuel worldwide. To avoid the worst impact of climate change scientists tell us that we need to reduce global carbon emissions by as much as 40% by 2030 and for that to happen the global community must take concrete imme...
