This paper illustrates that scientists have recorded a global rise in temperatures that influenced a series of negative events on the earth’s weather patterns. Currently, there is a significant rise in sea level, melting glaciers and intensifying rainstorms. Today, climate change is more profound than what previous generations had to endure resulting in a series of challenges to the world, particularly in the agricultural field. Climate is a dynamic system resulting from physical and chemical interactions in the earth’s structures. The Earth is made up of the atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere. The physical and chemical interactions of these structures result in the climate of a region. The atmosphere is part of the climate system that affects the earth directly. This is owing to the spherical nature of the earth. The sun heats up the earth, with more intensity on the equator and less intensity at the poles. This uneven heat distribution generates wind that carries the heat from the equator to the poles. The heat is also distributed from the upper-level surface of the atmosphere to the lower level of the atmosphere. The ocean correspondingly distributes heat but at a much slower pace than the atmosphere. The carbon cycle is a chemical exchange resulting from the interaction between the earth systems. The ocean and the biosphere are reservoirs of carbon. 99.9% of the CO2 on earth exists in the lithosphere. Carbon flows among the various reservoirs. Mathez states that photosynthesis by plants and decay affects the amount of CO2 in the atmosphere. This decaying and photosynthetic effect from the earth’s biosphere occurs after some time. Over a longer time frame, the ocean exerts a more dominant control on the atmospheric CO2. The ocean dominance is as a result of the amount of CO2 in the ocean that is 50 times more than the CO2 in the biosphere. The persistent balance that exists between the earth systems in the carbon cycle has maintained the conditions of the earth. It is as a result of this balance that the earth became conducive to evolution and survival of life. The interruption of this dynamic disrupts weather patterns and consequentially results in climate change.

It goes without saying that the proposed communication and awareness drive is subject to budgetary constraints. So it intends to compensate for the obvious budgetary constraints by focusing on the communication characteristics of the targeted customers and by being innovative and creative in its approach.
The result of global warming in animals and on agriculture and the effect on human inhabitants is indeed frightening. The earth is already on warming periods even before human predominance. Based on studies, from 1000 AD until 1850 AD, the rising of earth temperature is caused by the changes in activities on the sun and some volcanic eruptions.
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.
According to the paper, the effects of climate change are increasingly felt in many parts around the world. Human life and activities are affected by weather and climate, and changes in climate affect man and animals, food production, water sources and health. Short-term changes in climate can be classified as normal weather conditions.
The Arctic has been found to be the most vulnerable region to climate change. On the current trajectory, this region is already experiencing some of the most severe and rapid climate changes on the globe. However, effects of climate change in the Arctic have also brought in their wake prospects of oil, gas and mineral discoveries.
The climate system evolves in time under the influence of its own internal dynamics and due to changes in external factors that affect climate (called 'forcings'). External forcing includes natural phenomena such as volcanic eruptions and solar variations, as well as human-induced changes in atmospheric composition.
ibes climate as the aggregate changing mean pattern of atmospheric conditions over a long period characterized by the states and developments if the weather in a given area (p.2). Climate had cooled and warmed over million years ago long before the human race appeared on it.
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
