Coronal magnetic field and surface temperature change on Earth

In press with Geophys Res. Lett., May 1999

(Top) The coronal magnetic field, revealed by the eclipse on 24 October 1995. The dial plot shows the normalised radial component observed by Ulysses during its perihelion pass (13 September 1994 - 31 July 1995) (Courtesy Prof. Eijiro Hiei, Meisei University and Prof. Andre Balogh, Imperial College) (Bottom) The observed mean surface temperature change on Earth (blue line) and that inferred using coronal field estimates by Lockwood and Stamper (this issue). The black line is the average value and the yellow region bounds the uncertainty due to both the solar brightness extrapolation and the climate sensitivity. Solar brightening could explain roughly half of global warming during the last 100 years.
