This video gives a very basic explanation of what the greenhouse effect actually is, and how it is caused. It touches on the fact that, at the fastest rate since the industrial revolution, the Earth's climate is rising. The world is getting hotter, sea levels are rising, and the ice caps are melting. A common misconception of the greenhouse effect is that it is all bad; on the contrary, without the greenhouse effect, the world's average temperature would be around -18 degrees Celsius. With it, our average temperature is around 15 degrees Celsius. The problem lies within the enhanced greebhouse effect. Particles within the Earth's atmosphere ensure that a percentage of the sun's radiation is not realised out into space, but rather is reflected back onto the Earth. Unfortunately, the greenhouse gases created by human pollution, such as carbon dioxide, methane, and nitrous oxided, bind with these particles, and cause more of the sun's thermal energy to stay inside the thermosphere. This leads to climate change, and from there serious consequences.
