Ancient Antarctic dust reveals a hidden warning from the last time Earth was this warm
A new study of Antarctic ice cores reveals that volcanic dust patterns during the last warm period, 129,000 years ago, suggest local Antarctic ice melt contributed significantly to global sea-level rise. This provides a historical warning about how current warming trends might impact future sea levels.
Why it matters
Understanding the drivers of past sea-level rise is critical for climate modeling and predicting the impact of current global warming on coastal regions.
Every ice core drilled in Antarctica contains dust – tiny particles of rock blown in by wind. Scientists have traced the origins of this Antarctic ice core dust and found a remarkably consistent pattern.
