Global warming away, is the ice age here to stay?

The plants before the last ice age lived in a harsh environment probably meaning acidic. It is only make sense that the acidity was neutralized. The rain clean the air and produced more humidity and the last place the acidic levels were high were the Oceans. Clouds in the atmosphere made it colder and created Glaciers a couple miles high and that is a lot of water. There will be more volcano erupting before it can be noticed. I think that even the gravitational or magnet poles were stronger before the last ice age.
