Eesa11: lecture 4 - global climate change (part i) . Climate change: is a change in global or regional climate patterns. Climate change is not a new phenomena. Our current climate represents a warm interval between periods of glaciation. Changes in the position and elevation of continents. Changes in ocean circulation due to human impacts. Milankovitch variations in distance and orientation between the earth and sun. Variations in the composition of earth"s atmosphere. Global warming: is the observed increase in the average temperature of the earth"s atmosphere and oceans in recent decades. The earth"s average near-surface atmospheric temperatures has rose 0. 6 c 0. 2 c in the 20th century. Between 1955-1995, both north and south pacific ocean, atlantic ocean, and indian. Ocean, all showed warming of 0. 6 c between the surface of the ocean and a depth of. They absorb 80% of the heat added to the climate.
