Do ice cores help to unravel the clouds of climate history?

For the first time, an international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has investigated atmospheric ice nucleating particles (INPs) in ice cores, which can provide insights on the type of cloud cover in the Arctic over the last 500 years. These INPs play an important role in the formation of ice in clouds and thus have a major influence on the climate.
