Ice Ages. Our current climate regime -â a regime weâve had for the past ~2 million years â- is characterized by long periods of ice ages and shorter warm periods. The last ice age ended about 12,000 years ago, and since then weâve been in a warm period. Some argue that global warming is no concern, since the Earth will naturally switch back to an ice age. This is very likely to be true: an ice age is almost certainly in our planetâs future. But itâs a question of when. Our current concerns about climate change focus on the coming decades to the next century â- the time period relevant to our childrenâs and grandchildrenâs experience.
