For the last five decades a debate on climate change has rocked the world. Global warming due to human activities alarm is now an agenda in the world economic order. Scientists wrestle among themselves over whether climate change that brings global warming is entirely a man-made phenomenon.
They fight over whether climate change is real or not, they all wonder whether hard science justifies climate change that is entirely caused by emissions of greenhouse gases (GHGs), mainly carbon dioxide - CO2.
All scientists agree that there is climate change and that it is attributed to both natural causes and to human factors.
They also agree that emissions of GHGs are also causes of these climate changes. What they do not agree is the GHGs being the principal cause of climate change today. The reason to this disagreement is rooted in the fact that most scientists can’t comprehend the huge numbers of time scales that geologists use; hence most of the scientific community has little knowledge of geology.
In geology past climate changes, sea level changes, ice sheets come and go, life will always change, and extinctions of life will always happen. In a geological perspective, climate change variability is a complex phenomenon in which the atmosphere is influenced by geological processes like earthquakes, volcanoes, sun’s activity and cosmic processes.
