In-depths into Global Climate Change There have been increased concentrations of greenhouse gases emitted into the atmosphere following different human activities. Scientific evidence points out that this has seen the average Earth surface temperature rising by approximately 0.80C. About two thirds of this temperature increase was recorded in the year 1980 (Emmanuel 689). Scientists link these changes to increased combustion of fossil fuels as well as high rates of deforestation across the globe.

The main contributors are industrialized nations as they emit a greater percentage of greenhouse gases which further translate into adverse changes in the global climate. This has mainly been boosted by increased human activities. Kiehl and Trenberthnotes that “Atmospheric concentrations of some of the gases that produce the greenhouse effect are increasing due to human activity and most of the world's climate scientists consider that this is a significant part of the cause of observed climate change” (203).

The effects are however, felt worldwide. . Therefore, a greater portion of greenhouse gases emitted into the atmosphere is linked to anthropogenic sources and the effects are felt fromradiation of gases through the atmosphere. Moreover, most sources of human emissions are able to be identified in specific nations, but the impacts are felt in all areas of the Earth. Greenhouse effects occur and are felt when solar radiation heats the Earth surface after which the heat is radiated into the atmosphere in long wavelength radiations (Emmanuel 688).

From scientific view, the radiation is captured by atmospheric carbon dioxide and water vapour then reradiated. This causes heating of land, atmosphere and sea surfaces which then results into intense temperature levels worldwide. This is mainly attributed to the fact that warming effect of the land, oceans and atmosphere affect the global climate by increasing temperature levels across the entire globe. There is enough scientific proof of greenhouse composition and changes in levels in water bodies, land surface and in the atmosphere.

This rates carbon dioxide as the most steady greenhouse gas with a consistent increase especially in concentration. Other greenhouse gases have also been observed to substantially increase both in the concentration and volume thereby contributing to increased levels of temperature worldwide. Regarding all these, Kiehl and Trenberth point out that “these atmospheric concentrations to emissions sources and sinks are a steadily evolving sphere of scientific inquiry; certain inputs to the climate could be observed and promptly quantified” (198).

Electricity generation has been responsible for a higher contribution of carbon dioxide released into the atmosphere as compared to other greenhouse gases emitted. Even though
