What's happened
A team of scientists has successfully drilled a 2.8 km ice core in Antarctica, revealing ice that is at least 1.2 million years old. This research aims to enhance understanding of Earth's climate history and greenhouse gas levels over millennia. The project, Beyond EPICA, is expected to provide crucial insights into past climate conditions.
What's behind the headline?
Significance of the Findings
- Historical Context: The core provides a window into climate conditions from 1.2 million years ago, a period crucial for understanding glacial cycles.
- Greenhouse Gas Insights: Analysis will reveal how greenhouse gas levels have changed, particularly in relation to human activity since the Industrial Revolution.
Implications for Climate Science
- Understanding Climate Change: The data could clarify how past climate changes inform current trends, particularly regarding human impact on greenhouse gas emissions.
- Future Projections: Insights from this core may help predict future climate scenarios based on historical patterns.
Research Collaboration
- International Effort: The project involved scientists from multiple European nations, highlighting the collaborative nature of climate research.
- Technological Advances: The successful drilling at extreme temperatures showcases advancements in ice core drilling technology.
What the papers say
According to BBC News, the team extracted a 2.8 km-long ice core, which is expected to help unravel mysteries about Earth's climate history, particularly during the Mid-Pleistocene Transition. Prof. Carlo Barbante emphasized the significance of holding a piece of ice that is a million years old, stating, "You see the tiny bubbles inside, some bubbles of air that our ancestors breathed a million years ago."
The Independent reported that the core's analysis will provide insights into greenhouse gases, with Barbante noting that current carbon dioxide levels are 50% above the highest levels recorded in the last 800,000 years. Richard Alley, a climate scientist, expressed excitement about the advancements in ice core studies, stating, "This is truly, truly, amazingly fantastic. They will learn wonderful things."
AP News highlighted the project's goal to understand how atmospheric carbon has influenced climate, reinforcing the importance of this research in the context of ongoing climate change discussions.
How we got here
The Beyond EPICA project, funded by the European Union, aims to analyze ancient ice cores to understand climate evolution. Previous drilling efforts yielded cores up to 800,000 years old, but this new core extends the timeline significantly, potentially revealing critical data about climate cycles and greenhouse gas concentrations.
