"Life is name of the balance. So, stop Global Warming & save the nature"
Global warming is one of complex issue in front of the world. As we know earth has suffered from ice age in the past & it's main reason behind it is global warming. Actually what is global warming?
Global warming is the increase in the amount of temperature of Earth's atmosphere due to NO2, CO2, CH4, O3, Water Vapor…etc. In the mid-20th century and its projected continuation. According to the 2007 Fourth Assessment Report by IPCC, global surface temperature increased 0.74 ± 0.18 °C during the 20th century .Most of the observed temperature increase since the middle of the 20th century has been caused by increasing of NO2, CO2, CH4, O3 & water vapor, due to human activity such as deforestation & the burning of fossil fuel . Which block sunlight from reaching to the surface from the Sun, except this amount of sunlight absorbed by the earth surface is reflected back into atmosphere & then atmosphere reflects it out of the atmospheric zone. But in this process green house gases (i.e. CO2) block the process of reflection of light. Due to this temperature of atmosphere is increased.
Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 °C during the 21st century. The uncertainty in this estimate arises from the use of models with differing.
