Mission Plana. Analysis of the Problem1. 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 is a hoax, that the temperature

cycle is just experiencing an upward trend and will eventually come back down. Now,

however, we are starting to see the evidence of our behavior.

Remember the great heat wave in Chicago. That could have been a

consequence

of global warming. Nearly a hundred people died, and the city’s economy came to a

standstill. A much more tragic but less known heat wave smashed into India, causing

upward of 600 deaths.

Global Warming doesn’t only increase temperatures in hot areas. It also

decreases

temperatures in cold areas. An example of this has been the cold spell that struck the

midwest. In Montana, temperatures plummeted to 30 degrees below and stayed there.

The coldest weather ever recorded plagued our country’s heart for over three weeks, and

still hasn’t returned to normal. A related incident has been the blizzards of the east

coast.

Some places in New York State got over twenty feet of snow.

On a Native Island, where native tribes live, if the sea level rises

three fourths of a

meter then half of the island will sink. This will happen in many different islands around

the world and if the water keeps on rising as it is, then farming land near the seashores

will be flooded and the crops will be destroyed.

Like California and other states, we are adding CO2 and changing the

earth’s

weather. Some places are getting too little water which causes a drought and other places

get too much water which causes a flood.

In California, there was an almost permanent drought during the

eighties. This

was gone in the nick of time by the great rainstorms of 1995. We also experienced a

frightening cold spell in 1992.

The Road Ahead

With all these obvious scourges plaguing us now, it seems that things

cannot get

any worse. However, the current droughts, floods, and storms are just the tip of the

iceberg. If the greenhouse effect continues unabated, then the inhabitants of Planet Earth

have some surprises in store.

Scientists estimate that the global temperature will rise between 5 and

9 degrees

by the middle of the 21st century, accompanied by a sea-level rise of one to four feet.

Five

degrees may not seem like a drastic change, but in the last ice age at the beginning of

the

Quaternary period, the average temperature was only five degrees colder than it is now.

Thus, our actions our warming the earth enough to break out of an ice age.

Once the temperature reaches a certain threshold, the polar ice caps

will began to

melt. While those living in the Arctic may find that a welcome surprise, the implications

for the rest of the world are serious. Even a partial melting of the polar ice caps will

cause

sea levels to rise so much as to completely wipe out most coastal cities. This includes

such cultural centers as San Francisco and New York. Those cities that survive will be

battered down by hurricane
