The news media state that glaciers are melting. can you find examples of glacial melting prior to the evolution of humans in the geologic past? do you think that the climate will cool again? why or why not? go beyond just mentioning natural cycles and provide some specifics from our text

Glacial retreat occurs when ice melts faster than it forms.

Explanation:

Glaciers are large, slow-moving masses of land ice formed by the recrystallization of snow. For complex reasons, if the worldwide climate becomes cooler, and snow accumulates faster than it melts, the glaciers grow larger and cover more land. 10% of the Earth's surface today is covered by glaciers. Antarctica and Greenland are virtually covered by glaciers. At the height of past glacial ages, 32% of the Earth was covered by glacial ice. Most of Chicago is covered by glacial or glacial-related deposits.

Greenhouse (warm) periods: extensive and prolonged volcanic activity produces excessive carbon dioxide Thus based on above the glaciers have been melted in the recent past and still continue.  

Apart from this, the climate will cool again at the end of global warming and climate change. The natural cycle will change and raising the carbon content along with sea levels.
