Are we due for an ice age?
Coming out of the Pliocene period just under three million years ago, carbon dioxide levels dropped low enough for the ice age cycles to commence. Now, carbon dioxide levels are over 400 parts per million and are likely to stay there for thousands of years, so the next ice age is postponed for a very long time.
How does climate change affect the ice age?
These ice ages are triggered and ended by slow changes in the Earth’s orbit. But changing atmospheric concentrations of CO2 also plays a key role in driving both cooling during the onset of ice ages and warming at their end. The global average temperature was around 4C cooler during the last ice age than it is today.
How long will it be until the next ice age?
The next ice age almost certainly will reach its peak in about 80,000 years, but debate persists about how soon it will begin, with the latest theory being that the human influence on the atmosphere may substantially delay the transition. This is no mere intellectual exercise.
