| The earth has gradually been warming since the little ice age, again with a few peaks and dips in temperature. |
| Sunspot activity seems to have been less common during the little ice age, and this further confuses the issue. |
| The soil that underlies much of Dublin was deposited during the last ice age, about 10,000 years ago. |
| The lowering of montane vegetation belts in New Guinea during the last ice age was broadly synchronous with that of South America and Africa. |
| Rising sea levels and longshore drift since the ice age have created a remarkable, 500 km-long beach. |
| It is believed that a minor perturbation in solar heating caused by orbital changes could lead to another ice age or warming period. |
