a. Analysis of the Problem
1. History of the Problem
Some scientist's have been concerned since 1896 about what might happen if there
were 5.5 billion tons carbon dioxide in our atmosphere. In 1961 a British scientist did an
experiment showing that the carbon in the air was absorbing some of the sun's radiation.
Afterward a Swedish scientist, Suante Arrhenius, found out if the radiation of the sun was
trapped in the carbon dioxide the temperature of the earth would increase by 1-2 degrees.
In 1988 James Hanson, a respected scientist, told the U.S. Congress 'the greenhouse
effect is occurring now and it's changing global climate.'(1989 Koral). After the 1900's
people started making factories and started using fossil fuels like coal, oil, and aluminum.
It was the industrial revolution and overpopulation of humans that was the cause of the
environmental problems that we have today.
2. Human Activity Causing the Problem
The reason our Earth is getting hotter is that human activities are emitting too
much carbon dioxide into the atmosphere.
The radiation from the sun gets trapped in the
bag of carbon dioxide that surrounds our earth.
One main reason for the problem of global warming is the burning of fossil fuels.
Fossil fuels are coal, oil and natural gases. We use these fuels to run factories, power
plants, cars, trucks, buses, air conditioning and etc. The people of the earth are putting
5.5 billion tons of carbon, in the form of carbon dioxide in the air every year! Seventy
five percent of this is fossil fuels.
3. Impact Causing Global Change
For many years, scientists have been predicting that our disregard for Mother
Nature would make the climatic temperature of this Earth to increase greatly. There have
been arguments that the whole idea of Global Warming...
