Greenhouse Effect And Global Warming In Urdu

Certain gases in the atmosphere resemble glass in a greenhouse allowing sunlight to pass into the greenhouse but blocking Earths heat from escaping into space. The sun is much hotter than the Earth and it gives off rays of heat radiation that travel through the atmosphere and reach the Earth.

What Is Global Warming In Urdu Urdu Notes Global Warming Urdu Global

The normal temperature of the earth has seen a high shift due to the absorption of solar energy.

Greenhouse effect and global warming in urdu. These gases which occur naturally in the atmosphere include carbon dioxide methane nitrogen oxide and fluorinate d gases sometimes known as chlorofluorocarbons CFCs. The gases that contribute to the greenhouse effect include water vapor carbon dioxide. Thankfully greenhouse gases also save the day.

The past decade has been the hottest ever recorded since global temperature records began 150 years ago. Part of this radiation is directed towards the surface thus warming it. This video discusses the impacts of the suns energy Earths reflectance and greenhouse gasses on global warming.

The rays of the sun warm the Earth and heat from the Earth then travels back into the atmosphere. The greenhouse effect is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. It lasts an average of 12 years in the atmosphere.

The greenhouse effect happens when certain gasesknown as greenhouse gas escollect in Earths atmosphere. The studies grew out of a debate among doctoral students at WSU about why people dont believe in climate change Weber said. 4σT E4 4σ288K4 1560 Wm2 GH Effect 1560 Wm2 6 15 Wm2 945 Wm2 Let us compare.

Greenhouse effect confused with holes in ozone. These greenhouse gasses are carbon dioxide chlorofluorocarbons water vapor methane and nitrous oxide. General Physics an effect occurring in greenhouses etc in which radiant heat from the sun passes through the glass warming the contents the radiant heat from inside being trapped by the glass.

The Earth is wrapped in a blanket of air called the atmosphere which is made up of several layers of gases. The global average surface temperature rose 06 to 09 degrees Celsius 11 to 16 F between 1906 and 2005 and the rate of temperature increase has nearly. Environmental concerns have increased the rates of global warming due to the greenhouse effect.

The intensity of downward radiation that is the strength of the greenhouse effect depends on the amount of greenhouse. Human activities contribute to global warming by increasing the greenhouse effect. Methane is the next of the greenhouse gases which has the biggest effect on global warming 15.

Greenhouse gases include carbon dioxide methane and nitrous oxides. The greenhouse effect is the process by which radiation from a planets atmosphere warms the planets surface to a temperature above what it would be without this atmosphere. Researchers devised a pre-test examining 104 peoples basic scientific understanding of global warming.

Regardless of their political orientation most people taking the pre-test didnt understand the greenhouse gas effect. Radiatively active gases in a planets atmosphere radiate energy in all directions. We know the average surface temperature of Earth is about 15C by back calculation we see.

This is generated by activities such as livestock production agriculture sewage treatment natural gas and oil distribution coal mining fuel use and is also given off from waste tips. Solar input 1367 Wm2 greenhouse effect 945 Wm2. Global warming is the unusually rapid increase in Earths average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.

The greenhouse gases present in the atmosphere absorb this heat energy and disrupt the regulation of heat throughout the atmosphere. The excess heat in the atmosphere has caused the average global temperature to rise overtime otherwise known as global warming. Global warming has presented another issue called climate change.

These heat-trapping gases can be thought of as a blanket wrapped around the Earth which keeps it toastier than it would be without them. Greenhouse Effect and Global Warming. My calculations of CFC greenhouse effect show that there was global warming by about 06 C from 1950 to 2002 but the earth has actually cooled.

The greenhouse effect is the way in which heat is trapped close to the surface of the Earth by greenhouse gases.
