Global Warming

Global Warming

Many Americans don’t realize the how much their daily activities pollute the earth. Driving to and from work, using electricity, taking a hot shower, all of these things release some amount of carbon dioxide into the atmosphere and contribute to global warming. Global warming does not get as much attention as it really should, because in general, humans are far more concerned with other things. But it is a very serious problem that has some effects on humans now, and will have even worse problems in the future. However, it is possible to prevent global warming; it just requires a lot of cooperation.
There are various causes for global warming, but mainly there are two ...

long ago, since people didn't have thermometers, but they took a look at writings throughout history to back up the natural theory. "This began to change in 1984 when Willi Dansgaard of Denmark and Hans Oeschger of Switzerland published their analysis of the oxygen isotopes in the first ice cores extracted from Greenland. These cores provided 250,000 years of the Earth's climate history in one set of 'documents'(Singer & Avery, 1)." Scientists that study glaciers can take a look at different isotope levels of oxygen in the ice, and the carbon dioxide level, and make a precise decision about what the temperature was when the ice had frozen. What Dansgaard and Oeschger had found was a temperature cycle that was undeniable. True, the earth does have a natural cycle, but those who don't believe that humans can have an effect on our planet's atmosphere are severely mistaken. Is it not possible that we can enhance, increase, or worsen the earth's natural cycle?
The real cause to global ...

in the atmosphere thus raising the Earth's temperature, also known as global warming.
How do we know for sure that we're the problem? Most questions like this only require simple evidence and fact proving that carbon dioxide emissions have increased dramatically over time. From the 1950s to the present, the amount of carbon dioxide in the atmosphere been measured. Since then the concentrations have increased from 315 parts per million (ppm) to about 385 ppm (Schneider, 1). Scientists can even go back 650,000 years into the past by looking at gas bubbles in preserved ice in Antarctica. They can precisely predict the carbon dioxide level and even the temperature of so long ago. "...over ...
