| In this paper we give a short description of global natural disasters for
the Earth's civilization from space: 1) Galactic and solar cosmic ray (CR)
influence on the atmospheric processes; 2) Impacts of great space magnetic
storms during big Forbush-effects in CR, 3) Impacts of great radiation
hazards from solar CR during flare energetic particle events, 4) Great
impacts on planetary climate during periods of the Solar system capturing by
molecular-dust clouds, 5) Catastrophic disasters from nearby Supernova
explosions, and 6) Catastrophic disasters from asteroid impacts on the
Earth. Some of these problems have been already studied (see e.g. Dorman,
1957, 1963a, b; Dorman and Miroshnichenko, 1968; Dorman, 1972, 1974, 1975a, b,
1978; Velinov et al., 1974; Miroshnichenko, 2001, 2003; Dorman, 2004, 2006,
2008). We present here a detailed treatment of the first disaster only,
leaving to future papers the analysis of the other aspects. |
