Reconstructions of Antarctic local temperature based on the measured ratio of stable water isotopes within deep ice cores show a strong signature of orbital insolation variability 3,4,5,6. Recently, a ...

The pacing of glacial–interglacial cycles during the Quaternary period (the past 2.6 million years) is attributed to astronomically driven changes in high-latitude insolation. However, it has not been ...

In past ice ages, the intensity of summer insolation affected the emergence of warm and cold periods and played an important role in triggering abrupt climate changes, a study by climate researchers, ...
