Since we all realize about the grave problem of the worldwide - Global Warming -the biggest danger to human survival in the very coming future. People would have all the conveniences to make life easier, but the real question is to survive where will be the oxygen and controlled temperature?

Today we are encountering a pressing problem that is rise in the Earth's temperature. Global warming is what causes this phenomenon. Global warming is the phenomenon of increase in air temperature near the Earth’s surface.

Global warming is a significant environmental risk. This phenomenon takes place when trees are removed and the harmful gas like carbon dioxide is released into the air. The warming of the climate system is unambiguous and scientists are confident that it is caused by rising proportions of greenhouse gasses generated by human actions such as deforestation and fossil fuel burning. Causing polluted environment leading to survival of mankind very very difficult and distressful.

Extreme weather difference occurrences describe this global warming, including the following: Severe Droughts, Reduce in Rainfall, Extreme Weather Events, Evaporation, Rising sea levels, Warming of Oceans, Loss of habitat and so on.

Solving the critical environmental issue of global warming is perhaps the greatest challenge of 21st century.
