Antarctica’s ice sheet hit a climate tipping point 1 million years ago
Key Points
A new study suggests Antarctica’s ice sheet hit a climate tipping point about one million years ago, making it far more reactive to temperature and CO2 changes. Researchers warn this surprising sensitivity could offer clues about how the continent may respond to today’s warming world.
