Global Warming

In recent history, the issue of global warming has been something more and more people began paying attention to. Known as the increase in the temperature of the earth, particularly the air and oceans at the surface of the earth, global warming has been attributed to many different causes. As kids do science, global warming becomes one of the most important issues and points of study for children because it is a very real problem that the generation will have to face.

It is important to note the global warming itself is a naturally occurring phenomenon on earth. The greenhouse gases, which all naturally occur on earth are the reason why there is life on the planet. Without these gases helping heat the earth, the earth would be thirty degrees cooler, which means life on the planet would not survive. The earth's positioning around the sun, as well as volcanic eruptions have also been theorized to contribute to the global warming. Both these phenomenons are also naturally occurring. It is the increase of the earth's warming in recent years that has become worrisome for scientists.

The recent and rapid increase in the earth's warming has been attributed to the human contribution to global warming. Burning fossil fuel from factories, cars, and homes, and deforestation (and as a result the lack of carbon dioxide absorption by plants and trees) are part of the human contribution to the warming. When the gases get trapped in the earth's atmosphere, they trap the sun's heat along with them. When kids do science and raise plants in a greenhouse, the effect of trapping heat is the same, hence the name greenhouse gases.

When the temperature of the earth increases, the polar ice caps will begin to melt, causing the seas to rise, and some islands will disappear. Rising temperature will also result in the loss of several species, a change in the weather, and a change in food sources for the remaining species on earth. These effects are just estimates, as scientists are unsure how much the temperature will rise since the greenhouse emissions are difficult to estimate. Also, the warming of the earth may affect the different regions of the planet differently. Some areas currently uninhabitable may now become inhabitable.

As kids do science to understand global warming, the possibilities of slowing down the warming or lessening the human contribution can also be discussed. In the projects section, you will find how to recreate global warming in a container.
