There is no argument
From what I understand, prior to the big rock the only ice was very small polar caps. Affectively no ice.
The latest ice age began about 2.6 million years ago. It surges back and forth...cold then hot. Technically we are still in the latest surge of going back to hot. The latest cold surge began 110,000 years ago. Although it was just a surge of the overall ice age that has been going on for the past 2.6 million years, we commonly call this surge an ice age. That cold surge ended 11,700 years ago and we are now in a hot surge. There are still 3 major ice sheets left from the last cold surge, which means the warming surge has not finished yet, which means the planet is still getting hotter.
