Define soon LOL. The Earth is about 5 billion years old. Periods of glaciation (ice ages) have occured many times over the past few million years. They tend to occur in frequencies of 40,000 and, more recently, 100,000 years, related to Earth's orbital (Milankovich) cycles and precession. The last one ended about 10,000 years ago. We are in an interglacial period now (early interglacial-we still have extensive ice sheets in Antarctica and Greenland) and probably won't enter another period of glaciation for at least another 30,000 and maybe 90,000 years. So, not exactly soon in the time frame you're probably concerned about.

The climate is always in a cycle. We're warming a little bit now (supposidly), I'm sure we'll cool again. No one has anyway of knowing if we'll have a full ice age again (meterologists can't accurately predict 1 day in the future for one city - what makes you think they know what will happen in a year, a decade, century, or millenium?)

The short answer is "NO".
Because overpopulation, increasing levels of CO2, industry smoke etc. will cause greenhouse effect (within 12 - 15 centuries) and that will result in a fire age!
