Scientists have detected what they think is the source of a huge carbon 'burp' that helped end Earth's last ice age. As ice sheets melted around 19,500 years ago, CO2 gas in the atmosphere jumped by 50%. Researchers have now found evidence for the sudden influx of CO2 in the shells of tiny organisms called foraminifera, that once lived in the ocean. [Source: ABC Science]
