Global Warming Research

My theme for the Teen Life Project is Global Warming in general. As I was looking for some web pages to research on, I found this Wikipedia Global Warming Web Page.

I learned many things in this web page. Some of the things I learned is that global temperatures will be increasing from 1990 to 2100. I also learned that global warming can increase the rise of sea level and can change the pattern of precipitation. Global Warming can also have other causes such as the increases in frequency and intensity of weather events such as floods, droughts, heat waves, hurricanes, and tornadoes. In this web page I also learned that global warming is the term used for climate change and in this case it is used for recent warming. 1998 was the warmest year on history and the second warmest was 2005. The main cause of global warming are the greenhouse gases which are water vapor, carbon dioxide, methane, and ozone. The adding of carbon dioxide or methane in the atmosphere will increase the temperature on Earth's surface. The greenhouse gases could also produce the greenhouse effect which can lower 30 degrees Celsius of temperature on Earth. Earth would be uninhabitable if something like this happens. The ice-albedo feedback is an important feedback process which happens when carbon dioxide warms earth's surface and then ice near the poles begin to melt. Land or water takes the ice's place but land or water absorb more solar radiation than ice. This causes more warming and this warming causes more melting so the feedback process continues. The Kyoto Protocol is an organization that works against global warming. The science of nanotechnology could also help to defeat global warming. Global warming can also produce ocean acidification which is when carbon dioxide mixes with ocean water and makes carbonic acid. Global warming can also lead to ozone depletion which means that the ozone layer is getting thinner and there are some holes called ozone holes appearing on the ozone layer. Aerosols can also cause global warming by global dimming.

Now that I had read this web page about global warming, I think that global warming can really destroy our Earth. Global warming cannot destroy Earth only by causing the rise of temperature but by the increase of frequency and intensity of weather events. What really grabbed my attention is that there are so little things that we can do to fight against global warming. Not using aerosols could be one way of preventing global warming. Not using refrigerators that produce CFC's could also be a possible alternative of preventing global warming. When I think about this I feel like crying because Earth is so beautiful that I don't want it to destroy. I don't want human life to extinct and I don't want to die either! I think that if every one of us, residents of Earth, would help against global warming, we could save ourselves our at least save Earth.

I want to expand my topic by watching some interesting documentaries and by reading some more articles. Another way I could expand the understanding of my topic would be reading other people's posts. The last idea I would use to understand more my topic would be watching discovery channel programs about global warming or anything related to it.

"Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in arthropogenic greenhouse gas concentrations." This is the scientific opinion on climate change.
