The average temperature of the earth will be a cold temperature of -19°C without the natural greenhouse gases (water vapour, carbon dioxide, methane, nitrous oxide, ozone, and hydro fluorocarbons) which elevated the earth temperature to make it habitable at 14°C. These gases are becoming destructive to our planet through human activities which has been emitting these gases in large quantities into the atmosphere and thereby increasing the earth temperature to cause climate change which has been making wet regions wetter and dry regions drier.
National Aeronautics and Space Administration (NASA); A United States government agency that is responsible for the civilian space program, aeronautics, and aerospace research, reported that the August of this year is the warmest August ever since they started taking records from 1880; an evidence of the extreme rise in temperature. As a result of the already visible consequences of climate change around the world, UN climate summit coming up by 23 September which will have world leaders in attendance will be held to discuss drastic measures to decarbonise the earth.
Among the anthropogenic causes of climate change, Carbon dioxide contributes more to climate change than all other greenhouse gases and it is major root cause of CO2 emission is through the burning of fossil fuels (oil, gas, and coal) for energy production. As the temperature of the world gets warmer, glaciers melts and lead to increase in sea level which results into flooding in coastal regions around the world. Other sources of carbon dioxide emission into the atmosphere include volcanic eruption, deforestation, rearing of livestock, teeming world population etc. Deforestation increases CO2 quantity in the atmosphere through the absence of trees that helps in absorbing CO2 from the atmosphere.
Nigeria is yet to take drastic measures to mitigate CO2 emission into the atmosphere. Gas flaring and oil spillage due to activities of oil companies in the Niger Delta region is leaving the region polluted. Oil spillage makes it difficult for trees to survive by killing nutrients paramount to plants survival. The use of firewood and charcoal which are use to provide fire for cooking also emits CO2 into the atmosphere. Gasoline powered vehicles on our roads pollutes the air and also emit carbon dioxide into the air. The world is already experiencing the effects of climate change and not just from environmental.
This is also crippling the economy activities of countries around the world. Flood which result from warmer temperature caused by climate change evaporates water in large quantity from the earth surface to form cloud which later gives out excess rainfall has been leaving several displaced, some dead, properties wrecked, the source of livelihood of many destroyed with nations spending more money than they budgeted for to rebuild people and properties due to damage wrecked by flood and other natural disasters caused by climate change. The earth need to be safe from the destructive path climate change is positioning it to. Climate change is real and there is need for the world to act fast to mitigate the destructive gases in the atmosphere by reducing activities that contributes to CO2 emission into the atmosphere and ensuring cleaner energy are utilized for energy production.
