[1616] Global Change / Climate Variability, [5465] Planetary Sciences: Solid Surface Planets / Rings And Dust
Scientific paper
Among the most beautiful findings of the Space Age have been the discoveries of planetary rings. Not only Saturn but also Jupiter, Uranus and Neptune have rings; Saturn’s ring system has structures newly discovered; even Saturn's moon Rhea itself has a ring. All these are apparently supplied by material from the planetary moons (Rhea's ring by Rhea itself). The question naturally arises, why should the Earth not have a ring, and on the other hand, if it does, why has it not been observed? No rings have yet been observed in the inner solar system, but after all, rings in the inner solar system might simply tend to be fainter and more transient than those of the outer solar system: the inner solar system is more affected by the solar wind, and the Sun’s perturbing gravitational influence is greater. J.A. O’Keefe first suggested (1980) that Earth might have a ring system of its own. An Earth ring could account for some climate events. O’Keefe remarked that formation or thickening of a ring system in Earth’s equatorial plane could drive glaciation by deepening the chill of the winter hemisphere. (It is very well established that volcanic dust is an effective agent for the extinction of sunlight; this factor can be overwhelmingly apparent in eclipse observations.) O’Keefe died in 2000 and the speculation was not pursued, but the idea of an Earth ring has a prima facie reasonableness that calls for its renewed consideration. The program of this note is to hypothesize that, as O’Keefe proposed: (a) an Earth ring system exists; (b) it affects Earth's weather and climate; (c) the tektite strewn fields comprise filaments of the ring fallen to Earth's surface on various occasions of disturbance by comets or asteroids. On this basis, and drawing on the world's weather records, together with the Twentieth Century Reanalysis by NCEP/CIRES covering the period 1870-2010 and the geology of the tektite strewn fields, we herein propose the hypothesized Earth ring system’s orbital elements and structure. Our work concludes that rings may exist in Earth’s equatorial plane and in the plane of the lunar orbit, that such rings are filamentary structures comprising segments of geologically homogeneous material flung into earth’s orbit at distinct periods of lunar volcanism, and that earth’s weather may indeed be very strongly affected by the rings. In closing, until the time of the lunar landing in 1969, the moon was considered geologically dead. But today, we have multiple lines of evidence that the Moon is still volcanically active. According to our study, this volcanism may affect weather and climate considerably. If lunar volcanism and weather on Earth are linked, then a satisfactory understanding of lunar volcanism is called for by considerations of human welfare. The subsistence farmer has an immediate need to know what is true about our Moon; food security depends on it.
