CSIM from 80,000 light years

By 1939,  researchers speculated on the InterStellar medium (ISM) as a causative agent  for multi-millenial glacial climate oscillations [1].  By the mid 1970s, so called Climate Signatures of the Interstellar Medium (CSIM) researchers had access to improved observational and calculational technologies, as well as actual lunar soil samples.  This stimulated the ongoing efforts to relate ISM trajectories to climatic signatures on the Earth [2], [3], and [4].

The CSiM climate topics include the possibility that a periodic dust signature, covering at least one arc of our recent galactic revolution path (if not more), might provide temporal variations in some property that influences our Earth’s climate as it travels through. The implied impacts of the ISM upon the solar heliosphere and everything within, and the properties of the ISM required to impact climate on the Earth, are still poorly documented and more poorly understood.

CSIM enthusiasts hope to explore  among other topics, the open question of whether or not the  Extraterrestrial Dust Particle (EDP) signature over the past 1 million years of the Solar trajectory, can be reproduced conceptually and observationally.

Such a signature might be usefully evaluated against Earth’s past climatic history of the same time frame.

The presence of a compression dust wave as one possible conceptual model for EDP localization has been inferred in the recent past (Frisch and Mueller, 2011 [5, 6]) and might be further detailed, or otherwise supported at some time by remote dust or mass measurement techniques [7] applied toward the direction we came from (Sirius) and towards the direction we are heading (Vega), as well as the path between.

Ongoing explorations of the Local Interstellar Cloud, and the Local Bubble, and related timings of local supernovae are suggestive of support.

CSIM can also be broadly interpreted to cover ALL climate signatures, given that the solar system itself and everything within, are part of the ISM.  In particular, CSIM promotes stochastic explorations of the logical Solar and Orbital time series features in an integrated manner with hydroclimatologic index mainstays.
