  • Jean-Louis Le Mouël

In this paper, the 1978–2022 series of northern (NHSI) and southern (SHSI) hemisphere sea ice extent are submitted to singular spectral analysis (SSA). The trends are quasi-linear, decreasing for NHSI (by 58,300 km2/yr) and increasing for SHSI...

Is the Earth’s Magnetic Field a Constant? A Legacy of Poisson

  • Jean-Louis Le Mouël,

  • Vincent Courtillot,
  • Dominique Gibert and
  • Jean-Baptiste Boulé

In the report he submitted to the Académie des Sciences, Poisson imagined a set of concentric spheres at the origin of Earth’s magnetic field. It may come as a surprise to many that Poisson as well as Gauss both considered the magnetic f...
