Has something changed the voltage potential of the terrestial cavity to allow the accumulation of neutrons..?
Polarity..? Interference with diffusion..?
Is the atmosphere charging up due to low solar activity..?

ABSTRACT

The interaction of the heliosphere with interstellar clouds has attracted interest since the late 1920s, with a view to explaining apparent both quasi-periodic climate "catastrophes" as well as periodic mass extinctions. Until recently, however, models describing the solar windÈlocal interstellar medium (LISM)interaction self-consistently had not been developed. Here we describe the results of a two-dimensional simulation of the interaction between the heliosphere and an interstellar cloud with the same properties as currently, except that the H0 density is increased from the present value of n(H0)D0.2 cm~3 to 10 cm~3. The mutual interaction of interstellar neutral hydrogen and plasma is included. The heliospheric cavity is reduced considerably in size (approximately 10È14 AU to the termination shock in the
upstream direction) and is highly dynamical. The interplanetary environment at the orbit of the Earth changes markedly, with the density of interstellar H0 increasing to D2 cm~3. The termination shock itself experiences periods where it disappears, reforms, and disappears again. Considerable mixing of the shocked solar wind and LISM occurs because of Rayleigh-TaylorÈlike instabilities at the nose, driven by ion-neutral friction. Implications of two anomalously high concentrations of 10Be found in Antarctic ice cores, corresponding to 33,000 and 60,000 yr ago, and the absence of prior similar events are discussed in terms of density enhancements in the surrounding interstellar cloud. The calculation presented here supports past speculation that the Galactic environment of the Sun moderates the interplanetary
environment at the orbit of the Earth and possibly also the terrestrial climate.
