INTERSTELLAR DUST AS A CAUSE OF CLIMATE CHANGE

An email from Andy Nimmo [andynimmo@yahoo.com] below

The [much cited] 1939 paper, "The Effect Of Interstellar Matter On Climatic Variation" by Fred Hoyle and R.A.Lyttleton, in the Proceedings of The Cambridge Philosophical Society, which showed that when our Solar System passes through an interstellar dust cloud, the percentage of our Sun's radiation increases in direct proportion to the density of the dust and inversely according to the cube of the difference in velocities of the Solar System and the dust cloud, has almost certainly been mentioned in previous messages. Among other things they showed that very slight changes in these effects could bring about changes in radiation of from 1% to a 1,000%. They said whether there is an ice age or a heat age such as the Carboniferous, would depend on the relative velocities, lower velocities giving heat and higher velocities, ice. While there would be mass changes, these would be minimal.

Readers will recall that in 1977 NASA reported that both their Pioneer probes had found hydrogen and helium (10 particles per cc) flowing into our Solar System from ahead of the Sun's path in space at 72,400 kph and I understand the Voyagers also reported this so it hasn't come as much surprise that reports of global climate change have begun to come in since then.

So far as I'm aware, this hydrogen and helium is still flowing into our system - or has it ceased to do so and I've simply missed the report? Apart altogether from hydrogen and helium though, there seem to be some indications from recent analysis of dust captured by various probes in interplanetary space that at least some of this is carbonaceous and much denser than either hydrogen or helium. Do we know for certain that all such has been in our Solar System since its birth and that none of this more dense material is still flowing in?

Some now say our world is warming and some that we are cooling. Perhaps for political reasons born maybe out of jealousy of what they see as wicked industrialists and/or of envy of wealthier folk than themselves flying off to Spain or further for their holidays, rather than for scientific reasons, a large proportion of the warming lobby insist that this is caused by human CO2 emissions and that Earth's own environment has nothing or little to do with it. Clearly though, any such belief must result at least partially from ignorance as Earth's own space environment must scientifically affect our environment on the surface in some manner however small.

Accordingly it seems that Hoyle and Lyttleton have been correct to at least some extent whereby if hydrogen and helium and just maybe something else, are still flowing into our Solar System it must be in our interest to determine how much of what have entered our system, how much is still likely to do so, where in our system this is likely to accumulate and what effects this may have on our future? If our Solar System is entering an interstellar dust or gas cloud, how large is this and how long will we be in it?

While I am in no way trying to maintain that Hoyle's and Lyttleton's thesis is the sole cause of any change that may be taking place it does seem likely to be relevant to at least some extent so the above questions do need to be answered or the effect as more and more accumulates, perhaps between us and the Sun, may be much greater in the future without our having been properly forewarned. In view of this, might the expertise of a number of CCNet readers between them be able to come up with at least some of the necessary knowledge? Perhaps some are already trying to check the answers to these or similar questions?

I would expect that educated sensible Governments have already ordered that such research be undertaken. If not, I do very much wonder why not? It seems strange to me that the media don't seem to have mentioned this aspect of climate change at any time.
