Global Warming: It's More than Hot Air
When people hear the words global warming, they often make the mistake of thinking that they already know all about it. However, the issue of global warming is far more complicated than that and it effects everyone on this planet. This past month, we've been learning all about global warming in class and brainstorming ideas of how to help fix the problem.
First of all, what is global warming? The simple definition is that global warming means the phenomenon of rising temperatures in the Earth's climate. Global warming is caused by greenhouse gases. Greenhouse gases are gases in the Earth's atmosphere that cause radiation from the Earth to be re-directed back towards the surface. The four main greenhouse gases are water vapor, ozone, methane, and carbon dioxide. While there is a natural greenhouse effect, scientists have linked the increase of greenhouse gases and the spread of global warming to human activity.
Global warming has many different effects on the environment. First, it causes the glaciers to melt. This in turn causes sea levels to rise, which ends up creating huge floods. These floods often end up hurting people, damaging property, and permanently changing the landscape.
Second, global warming causes changes the Earth's ecosystems. For example, the increase of carbon dioxide in the atmosphere has been linked to increased acidity in the ocean. This can have an effect on the creatures that live in the ocean and can be very harmful to them. Scientists also believe that in addition to harming the ocean, global warming would have a negative effect on the land too, causing mass extinctions of animals.
Finally, global warming also has been linked to extreme weather patterns, including tsunamis, typhoons, tropical storms, heat waves, and cold waves. Extreme weather can cause lots of damage and they end up costing countries millions of dollars in disaster relief.
Our class is very committed to helping to solve the problem of global warming. One of the solutions we talked about is writing letters to our local congressmen. Politicians can help change environmental policies. Second, we can walk and bike more. Using cars less means less carbon dioxide emissions into the atmosphere. Third, we can use less water. It takes a lot of energy to give us clean water. By saving water, we save energy, and so, we reduce greenhouses gases.
It's been very interesting learning about global warming. It's a serious topic that we need to study a lot so that we can help keep the future of the Earth safe for everyone.
