Global Warming

1-Human activities like agriculture.2-Greenhouse gases such as Organic materials and deforestation.3-Concentration of carbon dioxide and level of methane.4-Smoking and factories, cars smoke.5-Increasing heat.

What is global warming?Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.
