Briefings

A 2026 study suggests global warming reversed a glacial period that began two thousand years ago, ending a new ice age. The evidence indicates that while the ice sheet grew in the 2000s, summer temperatures rose by the 1960s, causing the ice to shrink. This reversal occurred before the 1960s, meaning the warming halted an emerging ice age. The study does not specify the exact mechanism or the precise duration of the reversal, only that the trend shifted from growth to shrinkage.

Key points

• Two thousand years ago, the Arctic ice sheet began to grow, marking the start of a new glacial period.
• By the 1960s, rising summer temperatures caused the ice sheet to shrink, ending the previously ongoing glaciation.

Context

This finding challenges the timeline of recent climate change impacts, suggesting that warming effects can reverse established glacial trends within a few decades.

Limitations

The evidence is limited to a single study from 2026. It does not specify the exact mechanism of reversal, the precise duration of the glacial period, or the specific geographic regions affected.
