What is Global Warming?
To understand global warming a basic understanding of the greenhouse effect is required. Solar radiation absorbed at the Earth’s surface then heat is lost from the earth’s surface as infra-red radiation. The infra-red radiation cannot easily escape from the atmosphere. Some of it is trapped by a number of gases which resulting in the Greenhouse Effect. Global warming is the increase in average temperature of Earth due to the effect of Greenhouse gases. Greenhouse gases include carbon dioxide, methane, nitrous oxide, hydrocarbons. In 1896 Arrhenius was the first to claim that fossil fuel combustion may at some later time result in enhanced Global Warming.The observed rise in temperature over the 20th century was 0.3 to 0.6˚C. In 2014- IPCC release new report on Climate change, this report says that human activities are the dominant (95%) cause of the climate change. In this report human influence on climate is clear, the emission of greenhouse gases continue inc. 1983 to 2012 was the warmest 30 year off the last 1400 years. Fig- Greenhouse gases concentration
IPCC report says that according to a series of emission scenarios, global temperature is projected to increase by about 0.2°C per decade.
Causes of Increasing amount Greenhouse gases-
• Burning fossil fuels in Thermal Power Plant
• Chemical and Petrochemical Industries
• Deforestation
• Commercial Buildings
• Road transport
• Cement, Ceramic and Glass Production
• Livestock
