Will global warming end the ice age we are in?
Oracle is right. We are in an interglacial period of the ice age as opposed to the glacial. When the continents moved toward the north pole, providing a trap for ice to form, and when the Isthmus of Panama formed, and the subcontinent of India hit the Asian continent, weather patterns turned to an ice age. The Milankovitch cycle that were present before but not noticed as much created a cycle of about 100,000 years where there would be a long period of ice and then a period of warming. Fortunately, we are now in a period of warming based on past trends and we are near the peak warm period. Human emissions of CO2 probably have increased the temperature moderately but has not significantly changed the climate in my opinion, nor will it. It is likely that a new period of glaciation will begin in the next few thousand years but perhaps by then we will have the technology to avert it.
