Arctic ice had been expanding for at least 1,000 years before reaching its greatest extent around 1960; researchers say greenhouse warming then reversed a natural slide toward another ice age
- A new study suggests that the Arctic was already moving towards another glaciation nearly 2,000 years ago, before rising greenhouse gas emissions reversed the trend.
- Researchers found that the Barnes Ice Cap in Canada's Arctic began expanding again around that time, reaching its greatest extent in this advance around 1960.
- It has since retreated, reversing centuries of ice growth.
