What does global warming mean? Well, it is an increase in the earth's atmosphere's temperature. I explain a little more in this video below. If it does not load I suggest downloading Scratch. If you don't want to, here is a brief summary. When heat goes through the atmosphere from the sun's rays, some of the light ans heat gets bounced back. When the heat goes through the atmosphere, it warms up earth's surface. The heat will also try to escape but cannot due to earth's atmosphere. This build up of heat is called the greenhouse effect. Us humans cause some of it. We release carbon dioxide into the air with our cars and factories. Carbon dioxide is 53% of our greenhouse gases. It is not very strong, but there is a lot of it. There is methane and is about 1000 times more powerful than carbon dioxide. There is 12% nitrous oxide which is, once again, much more powerful than carbon dioxide. The remaining 18% are other chemical coming from air fresheners and air conditioners.

Water is a never ending resource, really. Yes, it will end in several billion years, but it has been around for millions of years, and still will be. In a million years, this will be ancient and people would be laughing going, "This is so stupid," just like we say to older inventions from hundreds of years back. By then I think something incredible would have risen to save power. But I think this would be a good temporary fix. Water is everywhere, yet nobody uses this strategy. But what about deserts, places with no water for miles? As you can see in my animation above (thank you []) that as water flows in the energy goes through the turbine and the excess water is released into a water. The energy flows through power lines and would carry the electricity to the desert.

3 reasons global reflections:
 * I contributed to this wiki by telling you about global warming and how it is caused.
 * I have learned that I think, global warming is real! It definitely isn't just a coincidence. The earth started heating up when cars came into use around the world. Cars release a lot of CO2 ad so do factories.
 * Where am I headed? Hydroelectric power! Water is EVERYWHERE! Yes, it would disappear, EVENTUALLY but it has been on the earth for many years (millions, actually) and will for many more.

Is global warming real reflection: Of course it is real! I earth is not just heating up. Ever since the invention of cars, mass producing, and deforestation. We are cutting down trees everyday and trees are what take the carbon dioxide out of the air. Cars burn fossil fuels and release a lot of carbon dioxide. Almost every country is full of cars and people drive them everyday. Factories release CO2 when creating stuff to make our world "easier", when really, all they are doing is making it worse!
