We're not in an ice age at the moment, but ice caps are still present.
Ice ages and ice coverage of Earth's land masses come and go. The last ice age was about 20,000 years ago, where ice and glaciers extended southward deep into Europe and over Canada and into the northern United States. The ice has retreated in current times, but ice and glaciers still cover a significant amont of Earth's land masses, especially in Greenland and Antarctica.
