Climate experts haven't even come to a consensus about the cause and effects of global warming, let alone whether it might prevent or trigger the next ice age. The question of whether reversing global warming might lead to an ice age could be irrelevant if it never happens.
These cycles of warm and cold take millions of years. They are caused by changes in the way the Earth orbits the sun and how it tilts on its axis, which affect how much of the sun's heat reaches the Earth. The last great cold cycle, which we know as the Ice Age, ended about 10,000 years ago. During the Ice Age, the Earth's average temperature was about 12 degrees Fahrenheit colder than it is today. That was enough to keep snow from melting during the summers in northern regions.
