An increase in ice caps can increase the Earth’s albedo and start a runaway cooling effect. Mass glaciation is a very real possibility. Most people don’t understand that we’re still in the Quaternary ice age. This is simply an interglacial period. Key geological requirements for mass glaciation continue to hold. The two big ones being the existence of a sufficiently large polar continent and multiple oceans, as opposed to a single large ocean such as during the Pangea period.
