Ice sheet expansion may have started 2,000 years ago, but we canceled that

A study suggests that the remnants of the Laurentide Ice Sheet in North America may have started to grow around 2,000 years ago, but a human-induced slowdown in global warming has paused or even reversed this process. However, new research indicates that this growth was short-lived, and the ice sheet is now smaller than it was 2,000 years ago. The study found that the ice sheet's expansion was likely caused by changes in the Earth's orbit and volcanic eruptions, which led to a cooling effect. However, human activities have since disrupted this natural process, causing the ice sheet to shrink.
