11. Read the following passage and answer the questions given below:
Increased social debate regarding complex issues such as the Greenhouse
Effect and Global Warming has definitely increased our environmental
awareness. However, such debates are often emotive rather than informative.
One can be forgiven. For example, for believing that the Greenhouse Effect is
something that we should trying to eradicate!
Short – wave radiation , in the form of visible ultra-violet (UV) lights from the
Sun, penetrates Earth's atmosphere to warm the surface of the planet. Because
all matter is warmer than space , it radiates heat, and part of the Sun's energy
is re-radiated out by the earth's surface. Greenhouse gases in the atmosphere
trap some of this infrared radiation causing the Earth's surface and lower
atmospheric layers to warm up to a higher temperature that would otherwise
be the case. Without these Greenhouse Gases, Earth would be a frozen, hostile
environment with an average Global temperature of about -15 degree C to -19
degree C , where no life could be sustained. A thermal balance of energy exists
where the Earth radiates about the same amount of energy into space as long-
wave radiation that it absorbs from the sun. Our atmosphere allows the
balance to be achieved because the trace gases trap and absorb heat.
Other interactions are at play that may affect the Earth's albedo or balance of
energy. The amount or type of cloud cover , for instance , can alter the amount
of energy being exchanged. Cirrus clouds reflect more of the Sun's radiation
than absorb radiation from the earth. Cumulus clouds do the opposite where
the proportion of energy retained is larger than that reflected.
The detected increase in carbon dioxide in our atmosphere since the Industrial
Revolution will also affect the albedo. Not only has there been an increase in
carbon dioxide identified. . Other greenhouse base gases such as methane,
nitrous oxide and chlorofluorocarbons have all increased. It is thought that the
latter of these minor greenhouse gases may have a stronger impact on global
warming than carbon dioxide levels.
The largest contributing factor to the increase of greenhouse effects has been
the burning of fossil fuels. Carbon in the fuel we burn is oxidized and released
into the atmosphere as carbon dioxide. Compounding the problem,
deforestation that has taken place over 50-100 years reduce the number of
trees that are necessary for absorbing carbon dioxide from atmosphere. Short-
term solutions for regional economic survival means the importance of
rainforests in this gas exchange has been ignored. Even a layman can see how
the Greenhouse Effect has earned its bad reputation. As out-of-control
Greenhouse Effect is often quoted using the example of Venus , where heat is
trapped by thick clouds and a dense carbon dioxide atmospheric element,
making the surface temperature as high as 50 degree C.
Scientists don't agree on these predictions. Whilst they agree that an increase
in Greenhouse gases will cause the Earth's temperature to rise, they disagree
on what may happen next. Some believe that the subsequent increase in water
may help to reduce the temperature. Others believe it will increase the
temperature. The collection of meteorological data from observation satellites
and a study of samples taken from glaciers and trees for example, support
what many of planet Earth's inhabitants notice for themselves. The globe is
warming up. It is generally agreed that by about 2030/2040 , the average global
temperature will have risen by anything upto by 5 degree C causing polar ice-
caps and mountain glaciers to melt and changes to ocean currents and
circulation patterns causing coastal waters to rise . New weather patterns and
extremes are anticipated.
Scientists do not know if the increase in average global temperature is just a
cycle because of the absence of long term meteorological data. Comparing
climate epochs is complex because so many atmospheric and surface features of
land and ocean are different.. All of these elements that make up climate are
continually changing and dynamically interacting. Knowing therefore, that the
limited worth in predictions for our feature. Moreover . Records of past climatic
epochs are not as reliable or detailed as those records developed in recent
decades.
General Circulation Models (GCMs) are designed to describe basic behaviour
patterns of the atmosphere. Used on super-computers, the system still cannot
represent all countries and has to rely on special representation of the earth.
This means that specific consequences of climate change – like predicting the
daily weather for specific climate regions – are more accurate in showing these
broader climatic conditions and predicting global effects than more localized
phenomena.
Many experts conclude that failure to take action in order to limit the impact
of human activity is taking a dangerous risk. Others argue that nature will
save itself from apparent inability or disinterest in protecting the planet and
that adaptation will , once again , be the key to survival. As these debates
continue and governments refuse to act, it is become more likely that we will
be able to see for ourselves, whether or not the dire predictions of global
warming are overstated as early as middle of the century.

(i) The Cirrus clouds reflect more of the Sun's radiation.
