Research Interests

Tropical high clouds are characterised by a near-neutral radiative effect, since reflection of short-wave solar radiation is balanced by absorption and re-emission of long-wave terrestrial radiation. However, this balance might change with ongoing global warming, which would cause a feedback effect of tropical high clouds, either amplifying or reducing global warming. 

Components and subsystems of the Earth system are expected to undergo abrupt and irreversible changes once global warming has crossed their specific threshold temperature, with negative consequences for human wellbeing. The scientific debate of such climate tipping points is burdened with high uncertainties, since current climate models are mostly not resolving them and evidence must be collected from different sources, including observations, paleoclimatic records and conceptual models.
