The disadvantages of Green house effect

1

Introduction
The Green house effect is the chief cause of
climate change which in turn is the primary
factor responsible for climate change. Before we
understand the main disadvantages of global
warming, it is essential to understand what the
green house effect is.

The Greenhouse Effect Explained

• Greenhouse effect is the mechanism by which
  thermal radiation from earths surface is
  reabsorbed by greenhouse gases and redirected in
  all directions. Some of the major green house
  gases are water vapour, carbon dioxide, methane
  and ozone. Most of these gases are poor absorbers
  of solar radiation, therefore allowing much of
  the solar energy to pass through the earths
  atmosphere thereby warming up the earths surface.

The Greenhouse Effect Explained

• On the other hand, a proportion of the outgoing
  energy is absorbed by these gases, which is then
  redirected to earths surface therefore further
  warming up the atmosphere. This is what is called
  a greenhouse effect. For ages there has been a
  delicate balance between how much solar energy is
  redirected to earth and how much is reflected
  back to the space.

The Disadvantages of Green House Effect

• Since green house gases helps to maintain the
  temperature, the primary effect of the increase
  in greenhouse gases would be on climate. This
  would mean warmer summers with natural disasters.
  Hurricanes have become common in recent years.
• Water level balance of the earth would be
  destroyed. Polar ice caps would melt leading to
  an increase in the ocean level. Floods will
  inundate low lying areas.

The Disadvantages of Green House Effect

• Marine life and ecosystem would be destroyed.
  Oceans absorb carbon dioxide thereby affecting
  the level of alkalinity. Many forms of marine
  life would be adversely affected if alkalinity
  increases. Polar ecosystems would be destroyed.
• Global warming would also affect the weather
  pattern. Rainfall would become erratic in many
  parts of the world. This might eventually lead to
  desertification.

The Disadvantages of Green House Effect

• The effect on human and economic life would also
  be tremendous. It is estimated that the rise in
  temperature would reduce global output by 2 to 3
  percent. This cost would run into trillions of
  dollars. As agricultural production is affected,
  this might lead to frequent famines and famine
  related diseases.

The Disadvantages of Green House Effect

Overall the impact of increased green house
effect on climate and human life would be
disastrous. The world community therefore needs
to wakeup now before it is too late.
