Human activities are the leading causal agents of anthropogenic climate change in contrast to the natural causes which cause climate change. Global warming and has been on the increase continued release of green-house gases such as Carbon dioxide, methane and ozone. Anthropogenic release of carbon dioxide is the leading cause of greenhouse. The gas comes from human activities such as combustion of fossil fuels, coal, oil and natural gas. Other leading causes of climate care changes in land use, deforestation, agricultural activities and soil erosion (Rapp, 2014).
The climatic geological time periods include the Phanerozoic which is divided into Paleozoic, Cenozoic and Mesozoic eras. The Proterozoic is divided into the Neoproterozoic, Mesoproterozoic, and Paleoproterozoic. The Archean divided into the Neoarchean, Mesoarchean, Paleoarchean and the Eorchean. All these geological time periods are dated about 66 million years ago to about 3600 million years ago.

Climate change has also been grouped in geological timelines. This aids in the listing of events of climatic history calendar including all known turn of climate events to paleoclimatology. Although much of the knowledge regarding climatic change diminishes as we get back in history of geological time. Known climatic ages are associated with processes such as glaciation ages, paleontology and geology (Stephenson, 2018) .
The increased combustion of fossil fuels threatens to exhaust the remaining reserves in a matter of years with very steep rising of carbon dioxide levels. With such a fast release, it will be difficult to re-adjust the atmosphere to the pre-industrial levels in the future. The great capacity to change climate remains still with humanity. The graph below shows different scientific measurements dated several years back up to date.
The observable effects of climate change include; shrinking of glaciers, breaking of ice into lakes and rivers, quick flowering of plants, shift in plant and animal ranges, accelerated rise in sea level, intense heat waves, and melting of sea ice. The overall integration is that the continued damage in climatic changes are significantly likely to increase in future days. Most of the causes of climate change are negative causes and rarely do we have a positive cause (Bryant, n.d).
Prospected future effects of climate change are on the increase and this may continue beyond this century. The magnitude, levels and rapidity of change of climate is primary dependent on the quantity of heat-trapping gasses which are emitted around the globe as well as the sensitivity of the earth towards such emissions. Temperatures are still rising following human-induced warming which is superimposed on the natural variations of the climate. Other effects of climate change in the future will include: Longer periods without frost, alterations in precipitation patterns, increased intensity of heat waves and drought, stronger hurricanes, melting of ice within the arctic regions and rising of the sea levels (Climate Change, Future Generations, n.d).
