EFFECTS OF GLOBAL WARMING – BENEFITS AND DANGERS
When
you hear about the effects of global warming it is important to
understand that the effects we are experiencing today are moderate
compared to what the future will see if we do not take preventative
action. Over the next century researchers and environmental
professionals are stating that the effects of global warming will
continue on a constant inclined curve. Temperatures heating up a little
bit each decade until the earth’s temperatures reach the sweltering
levels that we experienced in history.
Scientists believe that the earth’s temperatures will rise between 2-9
degrees Fahrenheit by 2050.
The
Arctic and the earth’s northern latitudes will feel the most of the
effects of global warming as they continue to escalate. As the Arctic
packs and glaciers begin to melt from the
increased temperatures the tundra and seas surrounding the areas will
continue to absorb the warmth which was once reflected back into space.
Climate models show that if temperatures throughout the rest of the
world rise to 3 degrees Fahrenheit they will more than likely rise to at
least 7 degrees Fahrenheit in the Arctic. From this the oceans
throughout the world will become full with melting glaciers and ice from
the Arctic likely to rise by at least 3ft.
As
the temperatures continue to rise this will force the ocean to
evaporate quicker and therefore more rainfall will be experienced. The
problem with this effect is that the rainfall may hit areas of the world
which do not need it at all causing massive floods and monsoons.
Subtropical areas like India are expected to be the target of this
particular effect of global warming. On the other hand it is safe to
say that droughts are going to be more of a problem than flooding.
There
are predictions that the future effects of global warming may have its
benefits as well. In the northern part of the world such as Canada, the
warmer temperatures will mean longer growing seasons and more rainfall.
This of course then will put an end to any food shortage that may be
occurring and provide a new sense of prosperity to countries throughout
the world which have been struggling to survive.
Many
of the changes and effects listed above are already taking place today
on a smaller scale of course. Sea levels are rising due to thermal
expansion of the ocean, in addition to melting of land ice. Amounts and
patterns of precipitation are
changing as well but only slightly in comparison to what has been
predicted for the future. Changes in temperature and precipitation
patterns increase the frequency and intensity of other extreme weather
events such as floods, droughts, heat waves, and tornadoes.
Other
effects of global warming include higher or lower agricultural yields,
further glacial retreat, reduced summer stream flows and species
extinctions. As a further effect of global warming, diseases like
malaria are returning into areas where they have been extinguished
earlier. This is only the beginning of the effects global warming can
have on our earth. As the greenhouse gases continue to increase and
enter the atmosphere these effects are only going to increase in
severity making it harder and harder to maintain our quality of life.
Many
people find it hard to believe that the effects of global warming can
become as severe as scientists are predicting but the
patterns support these theories. When you read studies comparing
today’s weather to weather 20years ago there are already signs proving
the effects of global warming. Pay attention to the weather today and
the severe weather being reported from all over the world and you will
begin to see the effects within your own life as well.
We
can all do our part to reduce the amount of greenhouse gases within our
atmosphere. No matter how small the act might be (saving electricity,
conserving fuels, etc) every action makes a difference when we are all
making these eco-smart decisions. There are no doubts that the effects
of global warming are only going to persist and increase if we do not do
something today. The fact is that even if greenhouse emission gases
were completely eliminated today it will still take years to eliminate
the threats of global warming. This is why it is so important to do what
we can today!
