Why It Is Very Hot in Recent Years

Attributes To High Temperatures

Experts are warning about the global warming and change in world's weather patterns that show a worrying trend. Many countries seem to ignore the recent natural disasters such as earthquake, floods and hurricanes. This is just but indicators of a global problem that is yet to hit the world if nothing is done to stop it. You have heard people talk about " a walk in the park." The feeling that come with nature is amazing.Nevertheless, we are our own enemies. Where did the glamour of the land go? The clean, fresh and pure water,the fertile and nutrients rich soil, the ambience of clear atmosphere and serene gardens full of birds with their melodies,where are those good times when one will walk down the stream and plug fruits from naturally growing plants? In the name of development, we have cleared vegetation and polluted water bodies. The soil is full of non-biodegradable material, plastics and glass. The city atmosphere is clouded with smoke from industrial activities. The results: Global warming, inadequate water for domestic use,loss of soil fertility and no fresh air to breath.I Iong for the green.

Why is climate changing?

  1. Industrialisation. Developimg countries are busy building up industries in abid to improve their economies. The mushrooming industries are set up without due consideration to the effects they pose to the surrounding environment and the whole world. Do you know even a slightest form of pollution cumulatively leads to climate change? Yes it does. Smoky atmospheres in major cities have made life a living hell. Wastes from these industries are dumped into the rivers, oceans and other water bodies. It's not safe to use this water for any purpose. We have seen protest about hazardous wastes in our communities, haven't we? Destruction of land terrain, stinks are unbearable. Governments have not moderated the Industrialisation process with best policies, laws and regulations that govern setting up of industries. Industries create jobs yes but for who? Natural disasters are wiping massive populations off the planet.
  2. Overpopulation. Worldometer estimates that the world's population in the year 2021 is 7.9 billion. This translates to new households, need for land, space and more resources for survival. Encroachment of water catchment areas and clearing of forests are all attributed to increased world population. The worst part of it is that apparently efforts to conserve the environment are not even more important to this ballooning population than meeting thair needs for food and shelter. However, longterm effects are worse than what we are currently experiencing. If we don't teach the young generation about the importance of having a clean environment and the consequences of destroying mother nature then there shall come a time when planet earth will not be habitable. Homes that use firewood for cooking and other domestic purposes will continue preferring it to renewable sources of energy. Population is growing rapidly and resources are diminishing rapidly as well. It calls for action. The little effort you put forth in conserving environment such as collecting rubbish and recycling and reusing items goes a long way in helping to reduce the cost in terms of negative impacts of climate change. Let us pull together to realize this global duty.
  3. Deforestation. It is the uncontrolled cutting down of trees. Trees are important part of the ecological balance. They are shelter to living organisms. They use up CO2 and release oxygen into the atmosphere. Humans and animals depend on oxygen to sustain life. Deforestation therefore increase the accumulation of CO2 in the atmosphere which in return absorb infra-red radiation from the earth's surface causing an increase in global temperature. It dries up water sources and exposes soil to erosion. Trees should be planted to replace those cut down. In fact, when one tree is cut, two and more should be planted. If we control cutting down of trees and boost the rate at which we plant trees we will soon recover our lost forest cover and consequently make the land more habitable to human, flora and fauna.
  4. Poor Farming methods. Modern methods of farming encourage use of chemical fertilizers and pesticides. Some of the fertilizers contain nitrogen compounds that break down and produce nitrous oxide. This gas causes acid rain that increases soil Acidity. CO2 form green houses in horticultural farms also results into increased global temperature.

Greenhouse Gases

These are gases that the ability to absorb heat from the surface of the earth and water bodies including oceans, rivers, streams, dams, oasis and seas. During the day, the sun rays hit the surface of the earth. Some are reflected back into the atmosphere while others are absorbed. At night when the atmospheric temperature goes down, the earth starts to emit its absorbed heat and due to accumulation of the greenhouse gases, the rate at which heat is lost slowed down by the greenhouse gases. This therefore makes the earth extremely hotter than it should be.

A list of Greenhouse Gases

  1. Carbon(IV) oxide
  2. Water vapour
  3. Nitrous oxide
  4. Chlorofluorocarbon
  5. Methane

Sources of Greenhouse Gases Human activities accounts to 90% above of the volume of greenhouse gases emitted into the atmosphere. What are these activities? Below is a highlight of human activities that contributes to the build up of these gases:

  • Industrialisation
  • Agricultural activities
  • Urbanization
  • Deforestation
  • Settlement

Now let us understand how these activities affect us and mother nature.

a) Carbon(IV) oxide

It is one of the most important gas as far as the life of plants is concerned. Plants utilize this gas in Photosynthesis to synthesise their own food. Since plants occupy the first niche ecological levels, it is equally as important as it is catastrophic if not balanced. Carbon(IV) oxide is produced by car exhaust systems, industrial chimneys, burning of fossils such as coal and fire wood.

b) Water vapour

This gas is water in gaseous state. When water evaporates from the source, it forms water vapour. Global warming itself increases the percentage of water vapour in the atmosphere. So that means that it is dependent on the global temperature. Other human activities that increase the level of greenhouse gases also increases the level of water vapour in the atmosphere.

c) Nitrous Oxide

Use of nitrogen-containing fertilizers in farms is the reason for accumulated nitrous oxide in the atmosphere. When crops utilize this chemicals they turn nitrogen into proteins and subsequently they are fed on by animals. Both plants and animals die and their bodies are decomposed by bacteria and fungi thereby producing Ammonia gas into the atmosphere.

d) Chlorofluorocarbon

Chlorine and fluorine gases are produced by industrial activities. Some of which are used in paper and pulp industries for bleaching purposes for instance chlorine.

e) Methane

Livestock farming is not meant only for production of meat and other products for human consumption. Farmers are using animal wastes to produce methane gas in Bio gas Digesters. Apart from methane being destructive to the environment itself, it also produces carbon(IV)oxide when burned for either domestic or industrial purposes.

Percentage contributions to global warming

  • Carbon(IV)oxide - 64%
  • Methane- 17%
  • Nitrous Oxide - 6%

Global temperature has risen by an average of 1.16°c as at the year 2021. This is awake up call to all nations and people of the world to take responsibility in conserving the environment so as to prevent further increases in global temperatures. It's not going to change until we make it happen.
