The first ice age, known as the Huronian glaciation, lasted approximately 300 million years, beginning around 2.4 billion years ago and ending around 2.1 billion years ago. This period was marked by significant glacial activity and is thought to be linked to a decrease in atmospheric greenhouse gases. The duration and impact of this ice age set the stage for subsequent glacial periods in Earth's history.
