Therefore, the response in the ISM to the present‐day warming climate is different from that to the warm LIG climate.Īlthough snow depth on sea ice is a key parameter for sea ice thickness (SIT) retrieval, there currently does not exist reliable estimations. Due to its special geographical location, that is, the north‐south orientation of land and ocean, the solar radiation changes in the LIG enhanced the land‐sea temperature gradient, and thus intensified the ISM. The changes in the ISM are mainly determined by the thermal differences between land and ocean in the region.
The warming in the LIG was caused by a changed distribution of solar radiation over the Earth in contrast, the current warming results from increased greenhouse gas concentrations in the atmosphere. In this study, we use the climate model simulations from EC‐Earth3 to explain why the opposite changes happened in ISM during LIG and the current global warming period. However, paleoclimate archives such as speleothems show a stronger Indian summer monsoon (ISM) during the LIG, in contrast to an observed weakening trend in ISM in the past century. The period of the Last Interglacial (LIG) is often referred to as a potential analogue for what a future climate may look like. One way to understand the future climate change is to learn from the past warm periods.
