The climate is the average weather pattern in the certain area experienced over a long time. Unlike the weather, which is the current atmospheric condition, climate changes very little over a long period of time. So, the climate is also not static and changes due to natural factors. But natural factors account for very little and slow changes only. Due to unchecked human activities, the climate of the globe is changing much more quickly than it would do naturally. Such a change is called climate change, which is one of the greatest challenges the world community is facing in the modern time.

Effects of Climate change

  1. The overall pattern of rainfall changes, some places receive the excessive rain that triggers landslides and floods while others get dry, unable to sustain settlement and agriculture.
  2. Global temperatures rise alarmingly.
  3. It is predicted that the rising global temperature causes ice caps to melt.
  4. Sea levels are rises, leaving low areas at greater risks of flooding.
  5. Grasslands and rainforest get contracted while deserts get to expand.
  6. It also reduces the production of agriculture.

Acid rain

When the various gases like CO2, SO2, NO2, combine with rain water then their respective acids are produced. These acids react on the ground along with rain water in the cocktail form. This process is called acid rain. In the atmosphere, these gases react with water vapour and formed their corresponding acids like H2CO3, H2SO4, and others. When rainfall occurs these acids get mixed with rain and forms acid rain.

damage by acid rain

Effect of acid rain

  1. The acidity of the soil increases which causes the reduction of productivity of the soil.
  2. The acidity of water bodies increases which cause the decline in the population of an aquatic organism.
  3. The historical monuments damage because of acid rain.



Methods to control Acid Rain

  1. Environmental pollution should be controlled.
  2. An alternative source of energy should be used.
  3. SO2, CO2 and NO2 producing industries should reuse those gases.

Very Short Questions

Climate change refers to the rapid and unnatural change in climate caused by unchecked human activities.

Climate change is connected with global warming as global warming causes climates to change. Even though, a warming trend is global, different areas around the world experience different specific changes in their climates, which have impacts on their local plants, animals and people.

The major effects of climate change are:

  • Heatwaves, heavy downpours, and sea level rise pose growing challenges
  • Change in timing of stream flow reduces water supplies
  • Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity
  • Extreme heat affects health, energy, agriculture and more
  • Decreased water availability will have economic and environmental impacts
  • Extinction of animals and species.

The effects of climate change already felt in Nepal are drought, forest fires and flooding. In Nepal, changes in monsoon pattern have greatly exacerbated the situation of an unacceptable presence of poverty and inequalities of opportunities in the county.

To control the climate change following steps should be done:

  • Green your commute
  • Be energy efficient
  • Infrastructure upgrade
  • Consume less
  • Stop deforestation
  • Pollution control
  • Expand forest areas

We can contribute to the control of climate change by following ways:

  • Controlling pollution
  • Conducting awareness problems to control climate change
  • Reduction of greenhouses
  • Energy conversation
  • Using renewable resources
  • Making environment greener
  • Stopping deforestation

The climate in the average climate of the earth or its parts due to the fluctuation in temperature of an atmosphere, the flow of wind and rainfall is known as climate change. It is changed in following way:
The atmosphere of the earth is made up of gas like nitrogen, oxygen, carbon dioxide, etc. Among them, some gases have more heat observing and storing capacity while others have less capacity. So, the change in the amount of results the change in temperature of an atmosphere. Static reveal that carbon dioxide, carbon monoxide, nitrogen oxide, methane gases are increasing in the atmosphere. These gases obstruct the way of the returning of the heat to the space. They absorb the heat or return it to earth, which causes the received heat to be more in amount than the returned heat i.e. radioactive rays. From this temperature of the atmosphere of the earth is increasing. So, the gases that effect in exchange of rays and causes climate change.

The factors are:

  • Earth-sun geometry: The earth revolves around the sun in its own orbit. The orbit of the earth is not totally round. It is elliptical. Due to this reason, it is hot when the sun is near the earth and vice-versa. Hence, it influences the climate change.
  • Solar output: sun is the major source of heat and light in the earth. All the other sources of heat and light are derived from the sun as a secondary source. Therefore, the climate of the earth depend upon the radiation of the sun or the solar output.
  • Atmosphere/ocean heat exchange: due to the heat of the sun, atmosphere/ocean get heated, it changed into vapor and move from one place to another with atmospheric pressure. This water vapor drops down as rain and other forms of water at a suitable condition. In this way, atmosphere/ocean heated exchange influence the change in the climate.
  • Volcanic emission: The volcano is an explosion of molten masses and gases from the core of the earth. This molten masses and gases also influence the change in the climate.
  • Continent drift: slow movement of the continent toward and away from each other during the history of the earth also helps to changethe climate of the earth.

The effects of acid rain are:

  1. The acidity of soil increases which cause the reduction of productivity of soil.
  2. The acidity of water bodies increases which cause the decline in the population of the aquatic organism.
  3. The historical monuments damagebecause of acid rain.

The methods to minimize acid rain are:

  1. Environmental pollution should be controlled.
  2. An alternative source of energy should be used.
  3. SO2, CO2 and NO2 producing industries should reuse those gases.
