There have been changes in expected climatic or weather conditions all over the world in recent years due to global warming and this has had great impact on human health, other animals and the environment. The entire world is experiencing an upsurge in atmospheric temperature and of course its impact. Everyone is talking about climate change but it did not just occur suddenly. Human activities created this monster and now the entire world is grasping under the weight of the impacts this phenomenon has brought.
Mankind has always been a problem to its own existence through its activities. The human (anthropological) activities that reportedly brought about global warming and consequently its twin climate change include use of fossil fuel, deforestation, bush burning etc.
For years, it has been postulated that human activities have the ability to change the climatic conditions of a region. The link with human and environmental health was however not well defined.

Global Warming: How It Started

Swedish scientist, Svante Arrhenius was the first person to give quantitative prediction of global warming as a result of increasing atmospheric carbon-dioxide in 1896.
Eunice Foote has earlier in 1856 theorized about the idea that the warming effect of the sun increased with the presence of atmospheric carbon dioxide.

However, Guy Callendar was the first scientist to link global warming with human activities in 1938. The industrial revolution between the 1700s and 1800s is attributed to be responsible for the beginning of global warming.
In 1712, British Engineer, Thomas Newcomen, invented the steam engine which paved the way for the large scale use of coal (fossil fuel) in industries. The black gold (crude oil) was later discovered and this revolutionized industrial developments. The drawback is that combustion of these fossil fuels involves emission of atmospheric pollutants such as carbon dioxide, carbon monoxide, sulphur oxides etc. These were later called greenhouse gases (GHG)

Climate scientists observed that the earth’s surface temperature increased by 1°C during the industrial revolution of the 1700s and 1800s.
Burning of fossil for energy production results in release of carbon dioxide (CO2) and other greenhouse gases (GHG) into the atmosphere. These gases trap heat from the sun on the earth’s surface leading to gradual increase of the Earth’s temperature.
The growing concern over the consequences of change in Earth’s climatic conditions and global warming resulted in the formation of the Intergovernmental Panel on Climate Change (IPCC) in 1988. This led to the first United Nations Framework Convention on Climate Change (UNFCCC) in 1992 and since then a Conference of Parties (COP) on global warming and climate change has been held annually. 

Impact of Global Warming
Everything on planet earth is affected by global warming.
• There have been severe heat-waves causing heat-strokes in man and animals. Heatstroke is presented by heavy sweating, exhaustion, dizziness and unconsciousness.
• Changes in precipitation patterns resulting in droughts, floods, storms in different regions of the world.
• Rise in sea level leading to erosion, loss of coastal land and loss of biodiversity.
• Reduced agricultural productivity which impacts global food security and ultimately increased food prices and famine.
• Global warming and its twin climate change resulted in loss of habitat/shelter for both humans and animals, disruption of the ecosystem.

Crude oil is the major culprit responsible for global warming through the emission of greenhouse gases during combustion and energy generation.
According to the Intergovernmental panel on climate change (IPCC), there is a need to cut emission of greenhouse gases by 43% to limit temperature rise to 1.5oC and avoid the worst impacts of climate change still to come. Truly, the world is in need of climate change solution more than ever before.
