2. Read the passage alven below and answer the questions that follow (12)
Of course, human activity is chiefly responsible for the increasing problem
of global warming. In the last century, the rapid increase in the
consumption of hydrocarbon as well as the vigorous expansion of the
industries and domestic markets for halocarbons have drastically altered
the atmospheric concentration of numerous cases. This has altered
nature's auto-balancing mechanism
As a result, the world is now struck with several environmental problems,
including the problems of acid rain, melting of glacial ice, large scale
evaporation of water in tropics, increase in cloudiness in higher latitudes
and so on. The implications of these changes on human life are likely to
be enormous and may cause a series of adverse effects.
One of the direct effects of global warming is the altering of the heat
budget and its regional variations in the atmosphere, the primary driver of
weather systems around the world. The potential impact of warming on
the monsoon in India is of serious concern. The warming, though
widespread across the country, is more pronounced over northern India.
An important effect of global warming on meteorological conditions is an
increase in sea surface temperature in the oceans around the subcontinent.
Food production and food security, fresh water supply, forest biodiversity,
coastal settlements, fishing and more will be adversely affected. India,
like most developing countries, is committed to the principle of common
responsibility in addressing climate change. India needs to chart multiple
strategies to cope with the impending threats of climate change which are
additional to the existing environmental stresses.
Pursuing a sustainable development model is critical to addressing climate
change in India and elsewhere. India should adopt strategies for
sustainable development irrespective of the climate change debate. It
involves economic growth, social equity and environmental sustainability

Answer:
(0) human activity is chiefly responsible for the increasing problem
of global warming. In the last century, the rapid increase in the
consumption of hydrocarbon as well as the vigorous expansion of the
industries and domestic markets for halocarbons have drastically altered
the atmospheric concentration of numerous cases.
Explanation:
(1) environmental problems,
including the problems of acid rain, melting of glacial ice, large scale
evaporation of water in tropics, increase in cloudiness in higher latitudes
and so on. One of the direct effects of global warming is the altering of the heat
budget and its regional variations in the atmosphere, the primary driver of
weather systems around the world
(2) The potential impact of warming on
the monsoon in India is of serious concern. The warming, though
widespread across the country, is more pronounced over northern India.
An important effect of global warming on meteorological conditions is an
increase in sea surface temperature in the oceans around the subcontinent.
Food production and food security, fresh water supply, forest biodiversity,
coastal settlements, fishing and more will be adversely affected. India,
like most developing countries, is committed to the principle of common
responsibility in addressing climate change.
(3) India should adopt strategies for
sustainable development irrespective of the climate change debate. It
involves economic growth, social equity and environmental sustainability
(4) An important effect of global warming on meteorological conditions is an
increase in sea surface temperature in the oceans around the subcontinent.
Food production and food security, fresh water supply, forest biodiversity,
coastal settlements, fishing and more will be adversely affected
Answer:
Global warming and human activity
Explanation:
Question No.1 ) How is human activity chiefly responsible for the increasing problem of Global Warming?
Ans:-Human activity is chiefly responsible for the increasing problem of global warming. In the last century, the rapid increase in the consumption of hydrocarbon as well as the vigorous expansion of the industries and domestic markets for halocarbons have drastically altered the atmospheric concentration of numerous cases.
Q.2.1) What are the problems the world is facing due to 'Global Warming'?
Ans 2:Global warming has altered
nature's auto-balancing mechanism
As a result, the world is now struck with several environmental problems,including the problems of acid rain, melting of glacial ice, large scale evaporation of water in tropics, increase in cloudiness in higher latitudes and so on. The implications of these changes on human life are likely to
be enormous and may cause a series of adverse effects.
One of the direct effects of global warming is the altering of the heat
budget.
Ques 3:How has 'Global Warming' affected India?
Ans:-The potential impact of warming on the monsoon in India is of serious concern. The warming, though widespread across the country, is more pronounced over northern India.
Ques 4:-How should india plan to cope with the danger of Global Warming'?
Ans:-India, like most developing countries, is committed to the principle of common responsibility in addressing climate change. India needs to chart multiple
strategies to cope with the impending threats of climate change which are
additional to the existing environmental stresses.
Pursuing a sustainable development model is critical to addressing climate
change in India and elsewhere. India should adopt strategies for
sustainable development irrespective of the climate change debate.
Ques 5:-What is the most remarkable effect of global warming on meteorological conditions?
Ans:-An important effect of global warming on meteorological conditions is an increase in sea surface temperature in the oceans around the subcontinent.
Food production and food security, fresh water supply, forest biodiversity, coastal settlements, fishing and more will be adversely affected.
