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.
About 700 million years ago, during the Cryogenian glaciation, runaway glaciers made Earth look like a snowball. The last ice age led to the rise of the woolly mammoth and the vast expansion of glaciers. But it's just one of many that have chilled Earth throughout the planet's 4.5-billion-year history. So, how often do ice ages happen, and when is the next freeze expected to begin? The answer to the first question depends on whether you're talking about big ice ages or the little ice ages that happen within those larger periods. Earth has undergone five big ice ages, some of which lasted for hundreds of millions of years. In fact, Earth is in a big ice age now, which explains why the planet has polar ice caps.
