Greenhouse effect

Turning to a specific cause of global warming which are the greenhouse gases that can make the atmosphere heats the earth when gases reflect toward earth. A natural greenhouse effect is created by the greenhouse gases. Joseph Fourier discovered the greenhouse effect in 1824. Without the increase in greenhouse gases temperatures on Earth would be an estimated 30 °C (54 °F) lower than what it is recently. Water vapor is one of the important greenhouse gases which causes about 36–70% of the greenhouse effect. Recently the concentration of CO2 in the atmospheric is about 383 parts per million and it is expected to rise in the future.
