The Earth's Climate is Changing Everywhere - "Will There Be Positive Effects from Global Warming?"
Possible Short-Term Benefits of Global Warming
It is certain that if there is enough of a rise in average
World temeparature, the effects of global warming will be
harmful, if not devastating, to human beings. If the temperatures get hot enough, causing the sea
levels to rise to a critcal point: Coastal cities could be destroyed, leading to an end to
the economic and social life as we know it today. Yet, there may be some short-term
benefits of global warming, prior to reaching the danger zone.
Health benefits - Most people prefer to live in a warm climate
as compared to a cold one. Not only are warm climates generally more
pleasant, there are some health benefits as well. People who suffer from
conditions worsened by the cold, such as rheumatoid arthritis, often
move to warmer climates in the winter months (snowbirds). A small amount of global warming could
allow such people to stay in their homes and extend the range of benefits from warmer temperatures to
higher latitudes.
One recent and extensive study of statistics
was carried out about the health benefits of warmer weather. Scientists studied the numbers
of deaths, in different months of the year, in places that get cold in the winter
and warm in the summer. It was determined that many more people die in the
winter than in the summer. This tends to support the benefits of
global warming.
It should be noted, though, that the statistics in this
part of the study did noit cover all of the variables. There are other considerations
during season changes that would not
occur in global warming. For example, days are shorter in winter, but
they would not be shorter if more global warming occurred. The longer amount of darkness
could be a factir ub wubter deaths.

More Food - In 2004, it was observed by lobster fishermen that
the warmer temperatures caused by global warming had affected their harvest.
There appeared to be an abundance of Maine lobsters living and thriving in the
warmer waters. The fisherman were both surprised and happy for the increase, but expected it to be
short-lived. The optimal temperature range for lobsters is probably very small.
For a few years global
warming maybe increasing the amount of corn, wheat, barley, and other grains that
are being grown. Warmer weather will increase the growing seasons for many areas. And
the additional carbon dioxide exposure may increase productivity as well.
There is some evidence of this happening. Wheat yields in China have
increased over the last two years. And may trees and other plants are flowering earlier in the
the year in the Northern hemisphere.

Again these are expected to be only short term benefits of global warming.
Current projections suggest that farmers will only
be able to keep up with demand for crops for a few more decades. Then world-wide shortages
are predictd with widespread famines. Countries that have not witnessed food
shortages in recent history may find themselves facing untold hunger problems.
As tmeperatures rise, there will be shift in where crops can be grown.
AgriculturAldouspi endeavors in tropical zones are
expected to decline rapidly as the temperature becomes too hot to support crops. The temperate
zones will be able to have better farming, and more of
the world's food plants will be grown there.
Some economists believe that global warming will be a boon
to international trade. They foresee that the loss of ice sheets in the
Arctic will open up shorter trade routes that have not been accessible in the past. This
should provide faster travel between Europe, America, and Asia.
Short term gains in prosperity due to global warming may occur over the
next few years for some populations. At the same time, tides are rising, hurricanes are appearing more frequently
And wildfires are more fierce. Will people see only the good aspects of higher temparatures and ignore
the current and future dangers? And is there an optimum world temparature that future generations can
inmpose in the world climate? There is no doubt that whatever the future holds, good and bad, wise
adaptations in how we produce and use energy today, can impact on how good or how bad the next 50 years
will be.
