if it is global warming, why is it so cold?

No.  If the planet were on a cooling trend, and stayed that way for a while, it might be heading towards a periodic Ice Age, as it has done in the past.  We would consume a lot more of outr limited energy resources just to keep ourselves warm.  Also, don't worry so much about Global Warming.  As I said before, nature goes through these cycles of warming and cooling.  Yes. humans have an impact, but it is small.

Actually we are going for Global Warming, where all teh Ice is going to melt and probably flood alot of places, the atmosphere is gettinng thinner and more ultra violates are entering earth. P.S. did you see any Acorns? Keep looking for it...

If the air cools to truly frigid Arctic temperatures such as -40 C and below then the moisture capacity of the air will be so low that likely not much snow can occur. Only at these extremely low temperatures is the phrase "it is too cold to snow" fairly valid.\n\nAt the temperature of absolute zero ( 0 K, -273 C, -459 F) all air including water vapor condenses and loses all molecular energy. The temperature can not cool below absolute zero. \n\nIts can't snow in deep space.......

Global warming is caused by an increase in greenhouse gasses in the atmosphere.  Global warming has been proven, the only people who argue against it have no understanding of science and no idea what is going on in the world.  Humans are not the only cause of greenhouse gasses, but we contribute to the problem greately.  The fact is that the earth cycles through warming and cooling periods but manking disturbs the normal process and increases the rate of warming (mostly by CO2 increases from burning oil.)  There are natural sources of CO2 and other greenhouse gasses as well, volcanoes can spew millions of tons of CO2 in a matter of days... the earth has supported life through very hot and very cold peroids, but there is NO realistic argument that humans don't influence global warming.\n\nThe greenhouse effect is necessary for life as well, if all of the CO2 was elimated from the atmosphere life as we know it on earth would end, the earth would be a frozen, barren wasteland.  Without any greenhouse gasses the earth would not maintain a reasonable temperature; nights would drop to -80 Celcius on the warm parts of the planet... \n\nThe earth will recover from all of the damage we do when we are gone... life adapts, species are eliminated every year, but no little coverage is given to the new species the are discovered every year... evolution is in progress, global warming is a change, not a destruction.

It's high in latitude where plant & vegitation growth are very limited due to cold climate\n\nhttp://en.wikipedia.org/wiki/Tundra

It's not cold enough.

I think snows are a thing of the past, because of global warming.

Its for the tax money. Global warming is just the excuse.

It gets colder as you go up through the troposphere because the air is "thinner".\n\nThere is less atmosphere here due to less gravity.\n\nB/c there is less air, there will be less heat. Air is an insulator that holds heat. Less air = less heat.\n\n:)

Back in the 70s it was global cooling.  How quickly things change.  Climates get hotter and cold in cycles.  And according to scientists, we've been experiencing global warming since the last ice age.  Doesn't secular history say that the world has already gone through a warming an dcooling cycle several times?  Global warming may be slightly accelerated by industrial activity, but the truth is that our climate is alot bigger than us.  It will get wrmer or cooler with or without our help.

we might freeze to death. depending on the  global warming nuts.

My opinion is that the ice is cold. What is yours?

global warming is definitely the answer.  once the polar ice caps melt, the temps will skyrocket.  i expect that this summer will be cool and wet also.  this will continue, more than likely, until the ice caps are gone, then no more moisture, just hot dry temps with no end in sight.

Well, the weather changes very quickly, however global warming has been happening for a while. It is in the past while predicting the weather is in the future. There is data that shows a warming trend on Earth. So, you can trust it, at least as fact that is IS happening. Most people agree on that. However nobody is sure whether or not this heating is natural or caused by humans.

honestly global warming is a big f'n lie. If anyone knew anything about meterological weather history, they would know this "overall world warm up" happens all the time, along with the "overall world cool down" if you knew anything about science in that area, you probably wouldnt be a crazy liberal. PS, driving a enviornlementaly friendly car isnt going to do squat.

You take all the temperatures across the globe and average them out and compare to the same day and time every year and when the average is steadily getting higher, like it is, its called global warming.\n\nThe ice caps start to melt, sea level rises, climate changes.  Just a whole lot of fun stuff like that.
