The regional increase in snow fall is chiefly due to CO2-induced global warming; globally, snow fall has been and will continue to decrease. Some of the papers on the subject:
None of these citations provide evidence to support the above contention of the casue of snow fall variability. There is no observable connection between atmospheric CO2 concentrations and snow fall.

It's been an observed fact over over 150 years, you stupid shit. Increased atmospheric temperature results in increased water vapor. As tjhe links I posted above demonstrate, IT'S AN OBSERVED FACT.
I do not respond to ignorant personal attacks.
Is there no moderator on these forums to enforce behavior? If not, I will have no part of this.
There is a moderator, and that's me. I will now delete the worst personal attacks that i find in the posts. Desertphile, please stop such personal attacks or you will be banned from the forum. That would be a shame, as you seem to have a lot of points/references to share, so PLEASE stick to that!

Hayduke: I admit that he posted a lot of links, but I also think you need to accept the basic facts that as the world heats, climate will change.
Canada is expecting yet another record hot year. Yet where I live has had heavier snow, and was very cold and wet.
Last year was the same by the way.
The point is that as climate changes, the effects from one region to the next will be different. Some will be winners and some will be losers. All models, data, and observations are showing this.
This is a direct result of CO2 \ green house gases, aka global warming.
Incidentally that last trend report of Canada's weather correlates nicely with the extent of ice melt;
|Oh yeah how come this|
|Well, that is a very good point that you make. While the arctic air mass is going to become warmer, it won't become too warm for there to be snowfall. Also, it will contain substantially more moisture. Larger ice free areas will also likely serve to increase the moisture content of the air in the arctic and far north. Therefore, I think that areas in the arctic and far north can expect increased snowfall. Additionally, if the arctic air mass warms, it may expand. The polar vortex would be likely to spread southward as a result of this, and may lead to nor'easters tracking south of where they ordinarily would. However, overall these regions would be likely to have reduced snowfall overall, because temperatures would be far warmer. |
The "snowmaggedon" event several years ago was caused by the jet stream going far south of where it ordinarily does. As a result, Washington, DC received more than three feet of snow!
Also, if the North Atlantic current were to shut down or slow down as a result of melting ice, many areas would likely experience drastically increased snowfall. The temperature difference between areas to the south of the jet stream and the north would be enhanced, causing the jet stream to become exceptionally strong, resulting in very severe winter storms of a magnitude we don't currently see anywhere. However, the global average would still be increased, because the air to the south of the jet stream would become far warmer than it is currently.
We MAY be having a climate change that is expressed in warming. This has occurred many times in the past - the most easily accessible is the Roman Warm Period circa 140 BC and the Medieval Warm Period circa 800-1400 AD. After these warm periods we generally had cold periods though after the Medieval Warm Period we had the extreme Little Ice Age.
Our present warm period appears to be spaced regularly from the others an hence makes the term "man-made" appear to be very unlikely.\
Or probably more importantly you should be shown some important information: NASA has been toying with the raw temperature records. They have changed this at least three times:
And the results of this manufacturing of data is this:
Pay particular attention to the area of the NASA temperature chart from 1979 to - present. Now let us look at Dr. Roy Spencer's temperature chart over that same period. Dr. Spencer was the head of the NASA weather satellite program and his chart is directly from the weather satellites:
Dr. Spencer's chart has a zero point line running through the middle. This is because the AVERAGE temperature change is about zero. If you don't know how to read charts like this it could appear to be rising somewhat but in fact it only shows normal weather variations and not climate change in this period.
CO2 DOES NOT cause warming in the Troposphere for reasons that have been known for over a century: The absorption bands of CO2 are three quite narrow bands. The emissions from the Sun hits the Earth and that warming converts the high energy visible wavelengths into the lower infrared bands. While the area in which this occurs is near the absorption bands of CO2 it is offset quite a bit and so there simply isn't very much energy in those bands to absorb. My estimation is that full absorption occurs somewhere between 200 and 250 ppm - so any CO2 above those levels have no energy to absorb and so cannot cause any additional warming.
If you must get angry get so due to what the environmentalists have been putting this country through.
I could go into the technical parts of all of this but these postings are all over these groups. Man-made climate change is a hoax. It was a hoax from the very beginning and now scientists are tired of remaining quiet in order to keep a liberal government from taking away their research grants.
What's really important?
