Scientists behind a study of carbon dioxide within bubbles from Antarctic ice cores want policymakers to adopt an earlier baseline for global warming.
In short:
Scientists say data from Antarctica ice core shows world has already warmed 1.49 degrees Celsius due to human activity.
The study calculates a pre-1700 baseline based off carbon content in the ice.
What's next?
Researchers behind the study want politicians and scientists to use their modelling as a baseline rather than a commonly used 1850-1900 time period when the Industrial Revolution had already started.
