Global warming is caused by increased greenhouse gases trapping heat in the atmosphere. Over the past 100 years, human activities like burning fossil fuels have released large amounts of carbon dioxide, the most significant greenhouse gas, into the atmosphere. This has led to rising global temperatures. Additional water vapor in the warmer atmosphere exacerbates global warming through a feedback loop. Individual actions like conserving energy and planting trees can help reduce greenhouse gas emissions, but governments must also take active measures to prevent global warming from worsening conditions on Earth.
This is our submission for the SciChallenge project.
The topic we chose to talk about is climate change. We talk about the consequences and also how to help prevent them.

Climate change is the current rapid warming of the Earth's climate caused by human activity. If left unchecked (and current responses are doing little to halt it) it poses an unprecedented threat to human civilisation and the ecosystems on this planet. Discover the causes and effects of climate change, but also solutions to reduce it. Find out how you can take action to save the environment. Find out how you can take action to save the environment.

1. Dear my teacher and all of my beloved friend. Good day..
Today, in a good occasion, I want to take a speech about Global Warming. One of the "hottest
topics in around the world.
Global warming is popular topics but sometimes most of us never realize what they had done or
contribution and make our world become hotter.
Maybe the first we must define what is global warming
What is Global Warming?
Global Warming is the increase in average temperature of Earth''s land , sea and atmosphere.
of course , we already know why we often feel so hot ... That''s because the effects of global
warming already severity ..
Of course , all of us need to know the causes of global warming .
In many reference, i got , some of factors cause global warming are :
1. Greenhouse Effect
2. Feedback Effect
3. variations in the Sun
Global Warming occurs as a result of increased concentration of greenhouse gases in
the atmosphere. The main greenhouse gases are water vapor, carbon dioxide,
methane, nitrous oxide and ozone. These gases do now allow all the radiations from
the Earth to escape back info space. This is known as the Greenhouse Effect. This
trapped radiation or heat helps to keep the Earth at a constant temperature.
Greenhouse effect is thus very important to main the temperature of the Earth at a
habitable level.
Over the past few 100 years, human have been burning trees and fissile fuels, thereby
releasing millions of tones of carbon dioxide into the atmosphere. The increased level
of carbon dioxide in the atmosphere has caused the temperature of the Earth to rise.
This, in turn, causes more water to evaporate into the atmosphere. Water vapor is
also very good at absorbing heat. This cause the Earth’s atmosphere to become even
warmer. Scientist has called this effect ‘Global Warming’. They have warned that
Global Warming could shift rainfall patterns, raise the sea level and alter the
ecological balance.
Well , it turns out we also play a very important matters and make earth condition become worse
...
Dear My Teacher and all of my Beloved friends
This is our Earth, Our Home,Our Life. Why we make our life and our home become worse. Save
it
Let us prevent start from ourselves , and from now on , not to make matters worse Our earth.
1. Efficient when we use electricity . Just Use Electricity as we needed . Do not waste electrical
energy even though we have much money to pay electricity bills .
2. Efficient use of water.
2. 3. Planting trees or plants around us .
4. Reduct the use of motor vehicles.
Perhaps as an individual , our task and ability is so limited. Of course it is expected that the
government is more active role in preventing global warming and can be bad for Our earth. The
effect of them is returned for us, all of us .
Let us prevent as much as possible the effects of global warming .
I say again, Save Our Earth, Our Home and Our Life now and Forever
Thanks for your attention.
