Global Warming by Clarisse

What is Global Warming?

Global Warming is a theory created by a Swedish scientist in 1896. Scientist predicted that it was carbon dioxide thickening the Earth's atmosphere, having more of the sun rays kept in the Earth, thus heating it up. They call this the “Greenhouse Effect” for that cause. This video by NASA has a better explanation on how the “Greenhouse Effect” is affecting us and our world.

 How are humans creating Global Warming? 

Some of the activities we humans have been doing have been affecting our environment, which had caused the “Greenhouse Effect” to happen. For example: burning up fossil fuels such as coal emits carbon dioxide into the air. We don’t use coal that often anymore, but we do use car oil. Car oil is also a fossil fuel. That is one way we are emitting carbon dioxide into the air.

 How are human affected by Global Warming?

As that video said, the Earth heats up. Vegetation will shrivel up in heat, more droughts occur, and many countries are being hit by more tropical storms. An example by one of those storms can be the typhoon that hit Philippines (September 27, 2011). The hot air, when mixed with cold air, usually creates more wind.

How can we stop Global Warming?

For now, all we can do is to do what our school is encouraging: be eco-friendly. Walk to school or ride a bike, and if you live far away. Finds ways to get around without having more carbon dioxide released into the air. It’s only one world; we have to take care of it.
