... We interpret the overall fall in sunshine duration as due to increasing cloud factors resulting from increased evaporation rates over the Atlantic as sea-surface temperatures have risen. ... Knowledge of such long term variability in the Earth's cloud cover is important input information for modelling past climate change. We have tried to assess the importance of cosmic rays as a link between solar activity and climate from a study of the ISCCP-D2 satellite cloud factors and Irish Sunshine data. ...

... Together, this small group works mostly in the field of Active Galactic Nuclei, exploring their distribution in parameter space (black hole mass, black hole spin, accretion rate) and their evolution in cosmic time. Since the growth and activity of the central black hole, on the one side, and the assembly of the host galaxy, on the other, go very tightly in parallel, the AGN evolution is a convenient window on the more general problem of the formation of cosmic structures. ...
