Global warming and climate change is a fact but don’t fall for any of the money grubbing hype associated with it. It happens all the time but takes a long time by human standards of time. The human effect is relatively small but we do need to reduce carbon emissions. When the carbon became trapped in coal and oil earth’s atmosphere cooled quite a bit. Our releasing it again is scientifically proven to be having an effect but that is very small compared to what even just one volcanic eruption does. That doesn’t mean we should continue to keep releasing it though. The technology for clean energy exists and has for a long time but big money rules (oil companies) and until we change our nature it always will. Ironically science has also shown that the particles emitted along with the carbon (pollution) have had some cooling effect that offsets some of the warming effect of carbon. Volcanoes have the same sort of balance because they emit particles too but the effects of carbon are longer lasting than the particles that fall out of our atmosphere in the form of rain. For a comet to affect our ecosphere or its temperature it must interact far more directly with the earth than just passing through the remnants of its tail. If there is any measurable change it is minute. This close to our sun the objects in the surrounding space become warm but space itself is consistent in temperature everywhere. The energy from our sun and the solar wind is what causes the tail of a comet. Out among the ort cloud, where most comets are believed to come from, that energy is so widely dispersed that it doesn’t heat the surface of what it touches much. If that same comet where to somehow become stationary in the shadow of a large body like earth it would become just as cold as it was way out there in the ort cloud. I posted a pic of comet Lovejoy because I like the name and the color green. It’s still visible in a telescope and even a good pair of binoculars. It was closest to earth around January 10th.

“You don't know for a fact that the icy wake of Comet ISON is not frigid and therefore responsible for the frigid winter that we have been having since January of this year, and did have in January of last year. What you stated is merely a speculation on your part, and not a fact.” – First off, whether or not a winter is mild or harsh is a regional topic at best. The winters where I live have in fact been mild for the last 5 years. Second I’m referring to known scientific facts that are well known to anyone who knows anything about astrophysics. If you can show me scientific data supporting your “speculation” I’ll consider the possibility. I’m not a recognized scientist but it is a favorite study of mine so until either of us can show definitive data it is merely speculation on either of our parts. Yet I’m confident that if we put this proposal to any accredited physicist I know what his or her answer would be. The only article I can find that is relevant at all to your augment is this; thewatchers.adorraeli.com/2013/04/20/metor-shower-from-comet-ison/and it makes no reference to the possibility of weather change or a cooling atmosphere at all. Where did you get this idea? If I’m wrong I would truly like to know. “This close to our sun the objects in the surrounding space become warm but space itself is consistent in temperature everywhere.”“That is speculation on your part, and not a fact. When a comet made of ice or frozen gas travels through space, then surely that space becomes colder than it normally is, and surely anything passing through that sector of cold space does then become colder than it normally is.” –No, it is fact. Space is a vacuum. You are thinking of space as having the same properties as an atmosphere when nothing is farther from the truth. This article may help you understand why that is; www.nasa.gov/pdf/379068main_Temperature_of_Space.pdfObjects in space experience temperature changes but space itself doesn't. Actually, that is not quite true, space is slowly cooling because our universe is expanding. “The idea that the icy wake of Comet ISON which the Earth travels through every January might be cold enough to significantly offset or slow down global warming or climate change, is a beautiful idea.” – Yes, it is, but it is not how things work. If the comet actually entered our atmosphere is could have some affect but the dust trail it leaves behind is too insignificant to create any change. They become tiny dust particles that slowly filter down through the atmosphere over a period of approximately twenty years or more. There is actually historical documentation to support your comet and war theory. I’ve long known the beliefs of such signs and I recently saw a program on it. Yes, many cultures often see the appearance of comets as signs of doom and gloom. Perhaps even as excuses to commit their atrocities. The same program went into the possibility that comets carry with them the building blocks of life and maybe even complex micro organisms or viruses but that hasn’t been proven as yet. Personally, I think the idea is quite likely to be true. There have been many plagues after the appearances of comets and falling stars through history. “I don't suppose that everybody reading this post is well-versed in astrology, but perhaps some of you are. If so, then to those of you that are, hello.” – While I’m more interested in astronomy I am a student of astrology too so, hello. There are a few of us here. Many people poo poo the idea that the stars can and do predict the characterization of individuals born under a certain sign or even predict future events but my mind is not so closed to the possibilities. I do see the relevance of the generalization argument but to me it seems there is too much accuracy to dismiss astrology as hokum.

Sorry. The link to the video in the temperature in space is broken on the page I linked to. Here is the video; brainbites.nasa.gov/tempspace.html#/temperature-in-spaceWhen you get into discussing the actual temperature of space it gets more complicated. Space isn’t strictly a vacuum nor is it at absolute zero but for all intents and purposes it is safe and ok to think of it that way. It is very close to these and for a long time our best scientists thought it was.

Here is one that is a history on astrophysics and telescopes. The explosion of information we discovered with telescopes and then again with larger telescopes. In the first three minutes it gives a synopsis on what we learned from passing through Halley's Comet tail. I grew up about 40 miles from Mt. Wilson and even closer to Griffith Park. They’re both a lot more fun than even the zoo for an inquiring young mind. Even today I own an 8” Hall telescope.

When I was a kid it was cold in the winter. When I was a teenager the winter was mild. When I was in my 20's the winter was cold. When I was in my 3o's the winter was warm. Now in my 4o's the winter is cold. Not sure, but there may be a pattern there It's called weather and it changes all the time.
