Comments on We Live In A Space Cloud
SF writers are a little more concerned about space clouds than most astronomers. (Read
the complete story)
| "Well, this is as good an explanation as any for why the Earth periodically experiences Ice Ages. Neutral particles would seem to indicate neutrons, flying through a cloud of them might 'warm up' space, exiting them might be the reason the earth cools. Just a thought, juuuust a thought." (Dewtey 2/12/2012 5:29:11 AM) |
| "Take a look at this article; here's an excerpt:
'One mechanism which can give rise to a notable solar/climate link was suggested by the late Edward Ney of the U. of Minnesota, in 1959. He suggested that any climatic sensitivity to the density of tropospheric ions would immediately link solar activity to climate. This is because the solar wind modulates the flux of high-energy particles coming from outside the solar system. These particles, the cosmic rays, are the dominant source of ionization in the troposphere. Thus, a more active sun which accelerates a stronger solar wind, would imply that as cosmic rays diffuse from the outskirts of the solar system to its center, they lose more energy. Consequently, a lower tropospheric ionization rate results. Over the 11-yr solar cycle and the long term variations in solar activity, these variations amount to typically a 10% change in this ionization rate. Moreover, it now appears that there is a climatic variable sensitive to the amount of tropospheric ionization - clouds. If this is true, then one should expect climatic variations while we roam the galaxy. This is because the density of cosmic ray sources in the galaxy is not uniform. In fact, it is concentrated in the galactic spiral arms (it arises from supernovae, which in our galaxy are predominantly the end product of massive stars, which in turn form and die primarily in spiral arms). Thus, each time we cross a galactic arm, we should expect a colder climate. Current data for the spiral arm passages gives a crossing once every 135 ± 25 Million years.' http://www.sciencebits.com/ice-ages" (Bill Christensen 2/13/2012 3:18:19 PM) |
