Since then, man has been moving forward in terms of technological advancement but overlooking the damages it is causing to the Earth’s atmosphere.
The greenhouse gases, which occur naturally, absorb the thermal infrared and warm the Earth’s temperature by 63 degrees Fahrenheit. This whole process is known as the Greenhouse Effect. The main greenhouse gases that are present in the Earth’s atmosphere are carbon dioxide, water vapour, methane, nitrous oxide and the ozone. (Maslin, 2007)
Carbon dioxide and other green house gases such as methane are added to the earth’s atmosphere by the burning of fossil fuels. Previously, the carbon dioxide levels in the atmosphere were in balance but today, human activities are releasing carbon dioxide into the atmosphere at an increasingly high level. The earth’s vegetation has not been able to take in and absorb the excess of carbon dioxide and thus, the atmospheric level of CO2 has increased.
Fossil fuels are burnt to create energy for humans in the form of heat, electricity and gas. Apart from making our lives easier, it has also emitted enough carbon dioxide into the atmosphere to cause climate changes.
Through the Earth’s natural cycle, large amounts of carbon dioxide are released in and out of the atmosphere annually and so the CO2 levels remained in balance throughout. However; scientists have confirmed that human activities add around 7 billion tonnes of CO2 into the earth’s atmosphere which ends up upsetting the balance. According to research, the trees and the oceans only absorb half of the carbon dioxide present in the atmosphere. The remainder stays in our environment for as long as 100 years.
Carbon dioxide is created from fossil fuels through the form of heat and gas. It is also released in natural processes like decay of organic matter. Apart from that, trees release CO2 into the atmosphere but due to deforestation, the absorption of this gas has

Indeed, a significant question then rises: Is climate change really happening or is it just a fraudulent fabrication of industrialists? The debates in response to this question have been numerous over the past years, and even since the nineteenth century.
This issue is extremely important because it can cause a lot of damage to human beings if nothing is done about it in the future. It can have life-threatening ramifications should nothing be done about it immediately. Methane is another very important greenhouse gas, large quantities of methane is produced by domesticated animals which again directly affects the environment.
Over a period of approximately 100 years, it has been observed that temperatures around the globe have been going up at a significant rate. It is estimated by many researchers that within this period, the earth’s surface temperatures have gone up by approximately 0.8 C, that may cause a significant imbalance in nature.
With the advent of industrialization the world has seen an increase in the level of pollution. Factories and industries started to pollute air, land and seas in the early parts of 20th century. At first the damage done to the environment was limited but contamination of earth’s atmosphere continued and the situation has come to a tipping point now.
Climate change can be due to: Natural variability – warming or cooling due to sun spot activity, solar radiation Human activity – burning of fossil gases into the atmosphere, causing enhanced greenhouse effect However, there is much debate about what causes climate change, and the UN Framework Convention on Climate Change refers to a change of climate that is attributed directly or indirectly to human activity that alters the global atmosphere.
The discourse would initially present an overview of global environmental change in general; prior to expounding on the identified factors that have been instrumental in environmental changes in contemporary times. Finally, from the review of relevant literatures on the subject, highlights would be presented to identify the effects of GEC and form the recommendations on how government and international agencies plan to address global environmental change to plan for the future.
In fact, the changes in climate are posing a significant risk on the agriculture, food and water suppliers while the effort of alleviating poverty, diseases and food insecurity are put on stake, while lives of many citizens in under developed countries are being affected.
Some people argue that human activities are causing global warming whereas others are of the view that solar variations are causing global warming. In any case, it is a fact that global warming and climate change problems are causing huge problems to people, animals, agriculture and environment.
The impacts due to global climate are categorized into three classes that include direct, in direct, and psychological. The in-and a converted environment from the initial climatic conditions direct impacts are those that result from the acute effects of extreme weathers conditions and events , which change the climatic environment.
Its effects are felt globally and one of the major effects is the changing weather patterns. Apart from affecting weather patterns and agriculture, it also affects ocean life. “Climate change is global in scope, but ecological impacts are often
