Why the level of greenhouse gases in the atmosphere is rising?
The level of greenhouse gases in the atmosphere is rising as the gases responsible are produced without any attempt to reduce the levels. The gases such as Methane, water vapors, Carbon dioxide ( CO2 ), Nitrous Oxide and especially chloroflurocarbons ( CFCs ) are increasing day by day as it is used in manufacturing many products. If such trend continues it may result in the huge climatic changes which may result in mass deaths due to extreme weather conditions and diseases caused by such gases
How is the greenhouse effect caused on a molecular level?
The greenhouse effect occurs when certain gases in Earth's atmosphere, such as carbon dioxide and methane, trap heat from the sun. These gases absorb infrared radiation emitted by Earth's surface, preventing some of the heat from escaping into space. This results in a warming effect on the planet.
Identify one important effect of the rise in the level of greenhouse gases?
One important effect of the rise in the level of greenhouse gases is global warming. Greenhouse gases trap heat in the Earth's atmosphere, causing the planet's average temperature to increase. This can lead to various consequences such as rising sea levels, more frequent and severe weather events, and disruptions to ecosystems.
How are excess greenhouse gases affecting the temperature of earth's atmosphere?
Greenhouse gases help keep the earth's temperature at a comfortable level suitable for human existence. When we increase the atmospheric concentration of greenhouse gases above their natural level, this leads to global warming, in other words higher average temperatures across the globe.
Do greenhouse gases increase global temperature?
Yes. In the absence of greenhouse gases, the world would be some 30 degrees celsius colder. At the other extreme, greenhouse gases contribute to the extreme heat on the planet Venus. So, a normal level of greenhouse gases, including carbon dioxide, is very desirable. The present increase in the level of atmospheric carbon dioxide is considered to be the main cause of increasing average global temperatures.
The amount of energy the atmosphere absorbs depends in the part on its level of?
The amount of energy the atmosphere absorbs depends on its greenhouse gas concentration. Greenhouse gases like carbon dioxide and water vapor trap heat in the atmosphere, causing it to absorb more energy from the sun. This leads to warming of the atmosphere and the Earth's surface.
How does heat affect the Earth's surface?
Infrared heat rises from the surface of the earth into the troposphere (the lowest level of the atmosphere). It is captured there by greenhouse gases, so the troposphere warms. This is called the greenhouse effect, and too much greenhouse gas means global warming.
What is happening to greenhouse gases?
Greenhouse gases continue to build up in our atmosphere. Recent measurements for carbon dioxide (CO2) are: Jan 2010: 388 parts per million. Jan 2011: 391 ppm. Jan 2012: 393 ppm. Fifty years ago, in 1960, levels were 318 ppm.
Which agreement seeks to control the level of greenhouse gases?
KYOTO Protocol
What is another name for enhanced greenhouse effect?
The greenhouse effect is the natural process by which greenhouse gases keep the earth's temperature at a comfortable level suitable for human existence. The enhanced greenhouse effect is the increase in greenhouse gases that is leading to global warming. The term "enhanced greenhouse effect" is also referred to as the "anthropogenic greenhouse effect" and is the idea that humans may have an effect on global climate. It is also referred to as the "runaway greenhouse effect".
How can the greenhouse effect and greenhouse gases cause problems with earths energy budget?
Earth's energy budget has been balanced for thousands of years. The natural greenhouse effect allows enough heat in and out of the atmosphere to keep it warm enough for life. Additional greenhouse gases, which we are now adding to the atmosphere and causing problems with the budget and the earth is warming up. This warming is causing climate change.
Can Greenhouse gases change Earth's average surface temperature?
Yes. They can and they do. Any increase in the level of carbon dioxide or methane in the atmosphere will result in an increase in average global temperatures. This typically results in evaporation of additional water vapour, creating a slight amplifier effect, to further increase surface temperatures.
