Antarctic ice cores offer detailed records of CO2 levels, showing a significant increase due to human activities like burning fossil fuels, impacting climate change.
Antarctic ice cores provide the longest and most robust records of atmospheric CO2 levels, dating back 800,000 years. These ice cores trap gases that diffuse into the snow layers, allowing scientists to directly measure past atmospheric composition.
The rapid increase in CO2 concentrations in the last 200 years is primarily attributed to human activities such as burning fossil fuels. This rise is unprecedented in Earth's history, as seen through various data sources including economic records and ice core measurements.
Measurements from the Mauna Loa Observatory and isotopic signatures indicate that the added CO2, mostly from burning fossil fuels, is contributing to the current levels of atmospheric carbon dioxide, impacting climate change and biodiversity.
