Thanks for your reply,

Eric; "how the heck do you even fathom whether Sirius has ice-ages?!? By
Sirius, I take it that you are referring to the A-type star with small
companion and brighest star in the sky? Or do you have another Sirius in
mind?"

Obviously your mind-set is in the gutter. Either that or perhaps you can
answer a couple of questions.

1) I never once stipulated that Sirius had "ice-ages". So where the heck
did that notion come from?

2) Earth has "ice-ages" roughly every 105,000 years, and why the heck do
you suppose that is?

Do you perchance think that our sun gradually varies itself by +/-5%
over a timeline of every 105,000 years?

Or, do you feel it's at all possible that the spectrum of our sun varies
itself by +/- 20% over that same timeline of every 105,000 years?

Do you think that our moon goes into some gradual mystical form of
becoming highly reflective on some 105,000 year cycle, lasting say
20,000 years worth before returning to its' basalt/coal like self that's
reflecting 11%?

Do you think those 20 meters worth of diatom shells piled high in so
many multiple places upon Earth transpired because of ??????

By way of Sirius I meant to be telling you (this time I'm not suggesting
a damn thing) that our solar system orbits about the massive Sirius star
system, and that there's been sufficient proof positive of this for
decades, if not centuries. I'm suggesting that at times our solar system
arrives well within 0.1 light year if not as close as 0.0086 light year,
thus for +/- 10,000 years we essentially have two suns (actually three
if you'd include the mostly UV worth of Sirius/b).

What do you suppose a million fold increase in near-UV and UV/a as
derived from the Sirius pair of stars is worth to our solar system?

Actually, over the 10,000 year window might have averaged as great as
100,000 times the present UV influx from Sirius as it's currently
cruising 8.6 light years and still in the process of going away from us,
which doesn't seem like all that much potential until that's compared to
the messily 68 w/m2 that our sun delivers. Not only is Sirius visually
so much brighter, but it's spectrum is shifted a good 150 nm towards the
UV spectrum, thus most of the Sirius intensity can only be appreciated
by the Kodak eye or of similar film and/or the likes of unfiltered CCDs
that are extremely sensitive to the similar spectrum of what the Sirius
star system delivers.

Of course, since you're acting somewhat Mr. Negative, chances are fairly
good that you're going to misinterpret this as some damn fool joke about
how another star system can influence the environment upon good old
mother Earth.

Tell me something that I actually do not know; such as how much of the
near-UV and UV/a energy is it going to take for accelerating the growth
of just about everything on Earth?

What if the average UV influx was merely doubled, thereby averaging 0.5
w/m2 and contributed 24/7 instead of the 0.25 w/m2 12 hours/day?

The total influx of our solar energy spectrum that's entirely UV has
been suggested as 68 w/m2, of which typically 0.25 w/m2 arrives upon
half of the surface at a time. What do you suppose 10 fold that amount
and essentially thereby affording our environment a 24/7 worth of dual
illuminations (half of which containing a great deal more of the near-UV
and UV/a energy) would do for the likes of Earth, Mars and even Titan?
