Is tere really global warming if it's so darn cold?

Yes.  It'll still get cold in winter.  We're talking about a change so far of 1-2 degrees.  It will still get cold for a long time to come, it's just that it will be a little less cold a little less often.  You're not going to notice it effecting day to day weather.  What's of more immediate concern is the rising sea level resulting from the melting of the polar ice caps.  This process will result in the gradual submersion of costal regions, and changes in ocean currents that will result in increased severe tropical storms.  This is what you're going to see first.  There's a long way to go (as in probably not in our lifetimes) before you'll start to see noticably higher day-to-day temperatures.\n\nAnd for anyone who says global warming isn't happening, I'd like to see an actual source supporting that claim (as in a web link or a scientific journal citation).  In all the studies I have seen indicating that global warming is not occuring have had serious methodological flaws, but it is impossible to argue with a mere assertion of knowledge.

here in san antonio we have had like one or two cold days this whole year.i know that in san antonio we have pretty warm weather anyway but when i was younger we used to have a ton of ice storms and at least one snow storm a year but now the temp rarely climb out of the 60s in the winter.right now the high is in the upper 70s and its feb.come on people lets get with it.global warming is not a theory it is observable fact

1.  Yes, temperatures actually have been rising - in certain places.  2.  No, it isn't too early to make predictions, as long as they are based on sound, unbiased scientific findings.  3. I believe that the warming is being driven by both people and natural causes.  We can do something about the former, but not the latter.  To what degree (no pun intended) each one is a factor is still up in the air, I think.  4.  Yes, it certainly could benefit some regions of the earth, but it would damage many populated regions tremendously.  That's why we need to try to slow down the human contribution a.s.a.p.

Yes it cdan be too cold to snow. \n\nThe driest spot on the face of the earth is NOT the Atacama desert, it is the South Pole. From the reference here are figures of mm. of precipitable water vapor in the air measured in 1995:\n\nSouth Pole \nPercentile, Winter  & Summer \n\n25%, .19    .34\n50%, .25    .47\n75%, .32    .67\n\nAtacama\nPercentile, Winter & Summer\n\n25%, .68 1.1\n50%,  1.0 2.0\n75%,  1.6 3.7\n\nThe Atacama is so dry that there are some places in the Atacam where it has never been any measurable rain recorded, in over 100 years of measurements. Yet, the driest season in the Atacama still has considerably more precipitable water vapor in the air than the most humid season at the South Pole.  \n\nSo the answer is, yes it can be so cold that there is no moisture in the air, so it cannot snow.

Yes, Global warming is a reality.  Anyone who says otherwise is ignorant.   Yes, the earth goes throgh natural warming and cooling phases, we are currently trasistioning into a "hothouse" from an "icehouse" which means we are in an inter-glacial period.\n\nHowever, Humans are doing their part to screw up the atmosphere.  CO2 is a gas that traps heat  and is emmitted by cars, factories, and anything else that burns fuel to work.  All anyone needs to do is look at a graph of the average surface temperture for the earth superimposed on the CO2 level and they will find they are identical in shape.  And the CO2 level has increased exponentially since the industrial evolution.  While the earth's natural cycles have varied the CO2 levels from 150 to 280 parts per million in the last 600,000 years, we are currently at 390 parts per million and rising fast.  No that is not natural, it is caused by humans.\n\nWhat can you do?  Buy a Prius.  Recycle.  Use less - ride you bike more.  Run your AC less, Turn off your lights.  All those hippie things that save energy - they actually work.

it means that it's really cold outside

It is indeed a threat...But so is global warming....have you noticed the weird weather lately?

It is clear that we are in a period of Global Warming.  The average temperatures are rising.  That is a fact.\n\nIf you mean, are we suffering from a man-made global warming, that is a tougher question.  A lot of experts have debated this and disagree.  Here in Florida, we have had two really bad hurricane seasons in a row, and a lot of people are scared that this is because of "Global Warming" but the experts at the National Oceanic and Atmospheric agency are reporting record warm temperatures and at the same time are downplaying the man-made causes by saying there is no "proof"\n\nAn interesting thing that may happen is that Europe may go through a mini ice age because of this warming.  There is an oceanic conveyor belt that helps distribute heat throughout the world.  This belt ends up in the Artic near Europe.  When the polar ice caps melt, there is an influx of fresh water that changes the salinity in the ocean up there.  This breaks that belt and so the warmth stays in the other portions of the globe.  There was a great special on this a couple of months ago on the History channel.\n\nI don't know if we are causing the Global Warming, but I do know that we are trashing our environment and we should be a lot better consumers so that our children and grand children will have a vibrant and healthy world to live in!

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...

Global Warming is a myth
998066
Global warming is the term used to describe how the average temperature of the planet is going up. No one denies that the temperature is, in fact, going up. Therefore, no one denies that global warming is a fact.\n\nHowever, according to studies of Antarctic ice, the average temperature of the planet has been rising for 6,000 years, which is well before the Industrial Revolution of 150 years ago. This proves that global warming is not caused by man. In that time, however, the rate of temperature rise has increased, which means that the actions of humanity probably has worsened the situation.\n\nThe critical facts about global warming are these:\n\nWhat are the effects of global warming going to be, and how can we prepare for them? Currently, no model of global atmospheric projection has shown itself to accurately predict to any degree the general weather patterns of the Earth (such as the number and ferocity of hurricanes). Until we come up with an accurate way of predicting the effects of global warming, preparing for them will be difficult and based upon conjectures, which are a difficult sell to taxpayers.\n\nWhat can be done to limit the effect of humanity on global warming in the future WITHOUT putting a major damper on economic growth and development, especially in developing nations? For example, all nations could agree to stop driving vehicles that use internal combustion engines, but to do so at once would devastate the economies of many nations. However, other options, such as diverting tax funds to subsidize the development of alternative-energy propulsion for vehicles, would accelerate the advent of such earth-friendly technology.\n\nAll in all, because of the massive stakes involved when discussing global warming (and the subsequent misinformation flying around about it), many people are confused as to the facts about it. I was hoping to be as informative and unbiased as possible.\n\nPlease let me know what you think!

Global warming is NOT a "natural thing."\nYes, our planet all on its own, for various reasons, does go through cycles of warmer and cooler temperatures.\nHowever, in the last 150 years we have added many billions of tons of carbon in various forms (carbon dioxide in the air is the biggest problem) to the planet's ecosphere -- more than any "natural" cause in the history of the earth.  \nI very much want to leave a habitable planet to my children, so they can do the same for theirs.  That means reducing humans' artificial climate changes which are causing a runaway greenhouse effect -- which is NOT natural.\n\nThe earth isn't going to "die" naturally for another 4.5 BILLION years or so -- why are you so relaxed about moving that deadline up by 4.9999 billion years?\n\n"only" girl -- it's not a theory, it's well proven.  You should keep up with science.

definitely. it's practically the one part of global warming scientists agree on.\nover the next century, we will see the oceans warming and thus expanding (sadly flooding places like Venice), also the polar ice caps melting (once again, not good. they keep the earth cool...see a vicious cycle?), not to mention serious climate change and animals migrating to the north to keep cool. it's already happening...yikes!

Correct. The man's a nut case - global warming is mainly from his hot air, but is otherwise a myth.

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.......

yeah I heard all the crap about the new ice age what a crock same thing about human activity causing global warming bunch of nonsense read the astronomy reports the sun is burning a little hotter it does this ever so often like during the middle ages and think about it haven't we been coming out of an ice age for the past ten thousand or so years does this not mean it has been getting warmer

Yes, global warming has started and finished and started and finished.\n\nThe earth has been much warmer before and much colder.  It will be both much warmer and much colder again many times.
