Green House Effect.
                     GREENHOUSE EFFECT
What is green house effect?
• The greenhouse effect is a process that occurs when gases in Earth's 
atmosphere trap the Sun's heat. 
• This process makes Earth much warmer than it would be without an 
atmosphere. The greenhouse effect is one of the things that makes Earth a 
comfortable place to live.

How does the greenhouse effect work?
• The greenhouse effect works much the same way on Earth. Gases in the 
atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a 
greenhouse. 
• These heat-trapping gases are called greenhouse gases.

What makes the earth warm?
• During the day, the Sun shines through the atmosphere. Earth's surface 
warms up in the sunlight. At night, Earth's surface cools, releasing heat back 
into the air. 
• But some of the heat is trapped by the greenhouse gases in the atmosphere. 
That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit on 
average.

How are humans impacting the greenhouse effect?
• Human activities are changing Earth's natural greenhouse effect. Burning 
fossil fuels like coal and oil puts more carbon dioxide into our atmosphere.

Observation of NASA
• NASA has observed increases in the amount of carbon dioxide and some 
other greenhouse gases in our atmosphere. 
• Too much of these greenhouse gases can cause Earth's atmosphere to trap 
more and more heat. This causes Earth to warm up.

What reduces the greenhouse effect on Earth?
• Just like a glass greenhouse, Earth's greenhouse is also full of plants! Plants 
can help to balance the greenhouse effect on Earth. 
• All plants from giant trees to tiny phytoplankton in the ocean take in carbon 
dioxide and give off oxygen.

CONSEQUENCES OF THE GREENHOUSE EFFECT
Ocean acidification
• The ocean also absorbs a lot of excess carbon dioxide in the air. 
Unfortunately, the increased carbon dioxide in the ocean changes the water, 
making it more acidic. This is called ocean acidification.

Thawing of glacial masses
• Glaciers retreat also has its own consequences: reduced albedo the 
percentage of solar radiation that the earth's surface reflects or returns to 
the atmosphere, a global rise in sea level and the release of large methane 
columns are only some of them.

Impact on agriculture and livestock
• Global warming has already altered the length of the growing season in large 
parts of the planet. 
• The same is happening with livestock: climatic changes are directly affecting 
important species in multiple ways: reproduction, metabolism, diseases, etc.

Desertification of fertile areas
• Global warming is having a profound impact on the processes of soil 
degradation and is contributing to the desertification of areas on the planet, 
a phenomenon that destroys all the biological potential of affected regions, 
turning them into barren and unproductive land.
