Climate change is one of the most controversial public policy issues facing the world currently. While there is nearly no argument challenging the certainty of the ongoing global warming, what is fundamentally being questioned is whether climate change is anthropogenic or simply a natural, recurring phenomenon upon which human events do not cast a major impact.
Science of Climate Change
An evaluation of the differing views on the obtaining global warming takes off from the fundamentals of the new science of climate change. This field shelters several disciplines including chemistry, meteorology, physics, biology, oceanography, biology, and even sociology (Global Climate Change).
The foundation of climate change science can be traced to Svante Arrhenius, a Swedish scientist who determined in his 1896 study that fluctuations in of carbon dioxide or CO2 could yield effects on the climate. Later, in 1938, Guy Stewart. Callendar, an English engineer, proclaimed that the increased CO2 levels had given rise to a warming trend (Scheider).
Greenhouse Effect
Because of the transparency of the atmospheric gasses to observable light, sunbeams can mostly enter the earth’s atmosphere and reach the surface, where it is absorbed and subsequently reemitted in the form of infrared

This climate is made up not only of the atmosphere and the hydrosphere but also of the cryosphere, biosphere, and lithosphere. Thousands of years ago, when nomadic humans discovered farming, they cleared vast areas of land, consequently casting significant impact on regional climate, a development that will be sustained for centuries since. Humans would involve in slash-and-burn farming and other farming practices, inland water guidelines or building development events that transformed how the Earth’s surface and near-surface winds of the atmosphere back-scatter solar radiation (cited in Hillerbrand and Ghil
