= = =__The Greenhouse Effect and Global Warming __= = = = THE GREENHOUSE EFFECT = The Greenhouse Effect is a natural effect on Earths lower atmosphere and it heats the surface of the Earth. The Greenhouse gases are water vapor, carbon dioxide and methane. These three gases act as a “natural blanket” by preventing the suns energy to go back into space. The greenhouse traps energy to warm plants. The Greenhouse Effect is necessary for our survival because it helps warm the Earth’s surface. If it didn’t warm the Earth’s surface, then our planet would be too cold for humans to survive.

GLOBAL WARMING: THE BIG PICTURE
Global Warming is an increase in Earth’s average temperature that causes changes in Earth’s climate. It is caused by methane and carbon dioxide. This can result from the Greenhouse Effect. It is predicted that climate changes are going to change in the next few years and it will hurt our planet. Global Warming is concerning because it can cause more hurricanes, tornadoes, heavy rain, droughts, hotter summers and milder winters.

Many things in our planet contribute to Global Warming. One thing that contributes is the Greenhouse gases that accumulate into the atmosphere. The Greenhouse gases contribute because people keep producing the Greenhouse gases which will later cause effects in nature. Some effects are floods, droughts, rising sea levels and more insects. Another thing that contributes to Global Warming is the burning of fossil fuels that create carbon dioxide. Fossil fuels contribute to global warming because the carbon dioxide is staying trapped in the earth. The last thing that contributes to Global Warming is the clearing of land. This contributes to Global Warming because trees cause more carbon dioxide and without trees, you can’t get rid out carbon dioxide. Global Warming can impact us locally in many ways. One way is by extreme weather. Extreme weather includes cyclones, floods and droughts. Higher evaporation rates will cause more rainfall in certain areas. Another way of how Global Warming can impact us locally is by oceans that are rising. This is happening because of water expansion through glaciers that are melting because the temperatures are getting warmer. Also, if oceans are rising, then plants and animals don’t have much land left due to floods. Rising oceans can flood small- low islands and some coastal areas. The last way of how Global Warming can impact us locally is by wars. The countries in war will mostly fight over water, food resources and energy.

You can put a stop to Global Warming! Some things you can do to stop Global Warming is to reduce, reuse and recycle. You can reduce by not using a lot of pieces of paper because it costs $100 million every year and it helps stop Global Warming. You can reuse by using reusable water bottles. This is a good thing to do because it’s a better choice for the environment than buying water bottles at the grocery store. So, it helps you save money. Also, it’s easier for companies not to spend money and buy water bottles. If we use reusable water bottles, it will help our landfills. You can also reuse by using reusable shopping bags. This is a great thing to do because you’re not wasting paper! The last thing you should defiantly do is to recycle! Recycling is a great thing because it reduces the reason for raw materials, so then we can save our rainforests. If we don’t use a lot of raw materials, then recycling will not use as much energy. Lastly, if trash is released from landfills, then recycling will help reduce pollution which is caused by waste.

** To sum up everything, the Greenhouse Effect can cause Global Warming through the Greenhouse gases. The Greenhouse gases are ** water vapor, carbon dioxide and methane. Global Warming is an increase in Earth’s average temperature. The Greenhouse Effect heats up the surface of the earth. The Greenhouse gases contribute to Global Warming as well as the  **burning of fossil fuels and the clearing of land. ** **Global Warming impacts us locally by extreme weather, oceans that are rising and wars. To stop Global Warming you can reduce, reuse and recycle. **
