Global Warming is a very real and very
large problem and as we just heard it has come to affect
us all. However, the atmosphere is a huge place and if
these greenhouse gases are everywhere in the world’s
atmosphere they can’t really be that bad for us in the
United States, right? Well, you’re somewhat correct,
greenhouse gases do not discriminate where they occur in
the atmosphere, and do not just affect us in the United
States, and they are a worldwide problem. As we now
know, the greenhouse gases that cause global warming are
created when we burn fossil fuels to create energy for
ourselves. While there are a number of fossil fuels we
use, we have become most dependent upon oil. In fact
Americans burn so much that it accounts for 40% of the
total energy used, it makes up 97% of the total
transportation fuels, and the United States is the
world’s largest user of oil. However, this doesn’t mean
that the United States is the sole beneficiary of the
blame for using oil. Oil, in addition to other fossil
fuels, is used to meet 90% of the world’s commercial
energy demand, and the results of global warming are
being seen around the world. The following are global
occurrences that show problems being created from
extensive fossil fuel use.
-
In the Andes Mountains of Columbia,
South America, Disease-carrying mosquitoes that can
carry dengue and yellow fever viruses are spreading.
They were previously limited to 3,300 feet but recently
appeared at 7,200 feet. The warmer temperatures towards
the higher elevations have permitted these insects to do
so.
-
The sea level has been rising and has
caused the loss of coastal land at Rufisque on the south
coast of Senegal, Africa
-
Also in Africa, Mt. Kenya's (Kenya)
largest glacier has been drastically disappearing. In
the last 100yrs. 92 percent of the Lewis Glacier has
melted.
-
In the Mediterranean, intense drought
and fires have destroyed massive amounts of land. Spain
has lost more than 1.2 million acres of forest to
wildfires in 1994, and 370,000 acres burned in each of
Greece and Italy in 1998.
-
Half of all Glaciers in the Caucus
Mountains in Russia have melted.
-
In Korea, heavy rains causing severe
flooding struck during July and August 1998, with daily
rainfall totals exceeding 10 inches.
-
In 1998 fires in the rainforests of
Indonesia claimed up to 2 million acres of land,
including almost 250,000 acres of primary forest and
parts of the already severely reduced habitat of the
Kalimantan orangutan.
Although these instances only scratch
the surface of a few of the problems caused by global
warming, they should stand as distinct examples of what
else could happen in the future.
