Current CO2 Rise Outpaces Natural Increases Over Last 50,000 Years
New research using Antarctic ice cores reveals today's carbon dioxide levels are increasing 10 times faster than historical peaks, primarily due to human activities.
- 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.
