Global warming in the world today. Facts and controls

We see some negative occurrences in the world today which weren't present when we were younger. Most of these occurrences are caused by global warming. What is global warming? What are some facts to prove that it does affect us? How can we control it? Read this article

What is global warming?

Global warming (or climate change) could simply be defined as the rise in temperature of the Earth's climate in a century scale and all of its related effects. We can deduce from the definition that:

  • Global warming is the increase in temperature. That is it is responsible for the hotter days and nights we experience
  • It is a worldwide issue
  • It started a very long time ago
  • It has side effects



Cause(s) of global warming

It is caused when pollutants like carbon dioxide (CO2) and other air pollutants (greenhouse gases) collects and absorbs sunlight and solar radiation that have bounced off the earth’s surface which is supposed to escape into space. Sadly, these pollutants that trap the heat can last for centuries in the atmosphere. This simply means that global warming is caused majorly by air pollution. The more we pollute the air, the greater the effect.

Effects of global warming

Worldwide increase of temperature­čî×

increase in temperature caused by global warming
We don't need anyone to disclose to us that these days, we've been feeling too hot because of the sun. Well, the sun didn't get hotter, global warming just got worse

Shrinking ice sheets

Size of ice sheets reducing
Parts of the Earth filled with ice are reducing drastically. This is affecting the animals that dwell in such regions because their habitat is reducing as time goes by.



Increase in sea level

Since the last century, the sea level rose about 8 inches. This figure however, doubled since the past two decades. We better be careful and control global warming before the Earth's water surface increases from 70% to 99%

Even more events

Over the years, high-temperature events have increased while low-temperature events have reduced, since humans emit more pollutants into the air, water surfaces have been absorbing such pollutants and the acidity of oceans have increased. We can't help but fear that these pollutants also directly affect both man and animals.

How to control/reduce global warming

Plant trees­čî│­čî│

Plants and Trees gain their nutrition from the sun through a process popularly known as photosynthesis. CO2 is a very essential component of photosynthesis since plants use it to produce oxygen (dispersing it into the air). This means that the more trees are planted, the less CO2 would be present in the atmosphere. Not to mention, trees add beauty to our environment.

Reduce waste

Some waste decompose and release harmful gases like methane (and others which are green house gases) into the atmosphere. Also, to manufacture items that become garbage (e.g. plastic bags, bottles, metal, etc) energy is required and harmful gases emitted into the air come as by-products

Reduce burning of fossil fuels


Fossil fuels are natural fuels (coal, gas, crude oil) formed by the remains of organisms. Petrol, kerosene, diesel, etc are products of crude oil. Burning these fuels release green house gases into the air. We can reduce the consumption of fossil fuels when we opt for alternative sources of energy like Solar panels, hybrid cars and others.
Install Solar panels to replace generators and other green house gases emitting energy sources

Decrease the effects of global warming with your day to day activities

  • Always fix your cars and never use cars that emit too much smoke
  • Reduce, Reuse, Recycle
  • Use energy efficient appliances
  • Save energy
  • Stop burning dirt and dispose them the right way
  • Always read articles and journals that direct you on how to reduce global warming
