As a matter of fact global warming is an beta phenomenon that is important for survival of life on Earth without which the earths temperature would drop drastically. Conservatives believe that till date there is no credible or reliable information about the phenomenon of Global warming. A thorough study of the Geologic time scale would reveal that instances of global warming has even occurred in the past with temperatures of Earth exceeding than what it is today. The Paleocene-Eocene Thermal Maximum (PETM) is one of the most recent cases of Global warming said to have occurred almost 56 cardinal years a go (Bowen et al, 2004, p.495). This not only caused warm temperature conditions but also caused release of almost 2000 x 109 metric tons of carboninto the ocean wet causing ocean acidification, a phenomenon which can be seen today (Zachos et al, 2005, p.1611). Today rapid acidification is attributed to global warming however such acidification is known to occur thousands of years ago when mans harmful anthropogenic activities did not exists.Global warming is known to be the major cause of melting of ice caps and uphill of the water level. However, recent studies of the polar ice caps have shown that in most areas of the Arctic the ice caps have thickened. GIS images have shown that in 2012 polar ice-caps covered almost 3.91 square kilometers whereas as of 2014 the polar ice-caps cover almost 5.62 million square kilometers which is in contrast to the global warming model (Rose, 2014). If mans activities were to be the cause of global warming then such a phenomenon would not have oc curred since Man
