Overview

• The study analyzed ancient gases trapped in Antarctic ice to create a 50,000-year timeline of CO2 levels.
• Researchers found that the fastest natural CO2 rise in the past took 55 years to achieve what now happens in just 5-6 years.
• Periods of rapid historical CO2 increases, known as Heinrich Events, were linked to dramatic climate shifts.
• Strengthening westerly winds are reducing the Southern Ocean's ability to absorb human-generated CO2.
• The findings highlight the unprecedented nature of current CO2 levels and the urgent need for climate action.
