What's your opinion on global warming effects on polar bears and what can be done to stop it?

in my opinion is it doesn't exist. because think about it we are coming out of an ice age. it makes sense doesn't it? fact: there have been ice ages. fact: there is a lot of ice in ice ages. so if you know about water then you know the same amount of it is here that was here when the earth began so literally it is dinosaurs piss. well during an ice age lots of stuff is covered in water/ice ( i know i live in Minnesota and it is known that it was fully covered with ice.). so where is all the water? in ice bergs, glaciers, etc. so it would make sense that to leave an ice age most things would melt right? so they are still melting they will finish melting and cover parts of the world, then it will slowly freeze causing an ice age. why would humans make that big of a difference? we are insignificant to the world.(everyone in the world could fit in Texas and it would only be as densely populated as NY city). so our vehicles and combustible engines couldn't have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasn't but it was because of the CFC's(chloral floral carbons) which broke up the ozone by attaching to ozone molecules. but the CFC's are no longer around. the ozone is healing itself as it is meant too. their was no real hole only a thinning which is also bad. but now it is closing up and returning to normal. if you think that the co2 we produced cant be good well think about it it isn't that much and while the earth was cooling after being created it released tons of co2. so what people will notice in the next 1-9000 years is it will warm up but in that time it will also cool down and eventually there will be an ice age. just because the great human race is here doesn't mean that the earth will stop having ice ages as it has done by its self for billions of years. think about it. am i a genius or what i mean i just looked at what has happened in history wow who would have thought history would repeat its self\n\nnow to give you sorces and go into more depth on what i just wrote\n\nwell lets see first. ice ages.\n\nAn ice age is a period of long-term downturn in the temperature of Earth's climate, resulting in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers ("glaciation"). Glaciologically, ice age is often used to mean a period of ice sheets in the northern and southern hemispheres; by this definition we are still in an ice age (because the Greenland and Antarctic ice sheets still exist). More colloquially, when speaking of the last few million years, ice age is used to refer to colder periods with extensive ice sheets over the North American and Eurasian continents: in this sense, the last ice age ended about 10,000 years ago. This article will use the term ice age in the former, glaciological, sense; and use the term 'glacial periods' for colder periods during ice ages and 'interglacial' for the warmer periods.\nMany glacial periods have occurred during the last few million years, initially at 40,000-year frequency but more recently at 100,000-year frequencies. These are the best studied. There have been four major ice ages in the further past.\nso we are in an ice age interesting that means it is warming up. well that is my argument but there is more so i will continue.\n\noh my sorce for the above exerpt is http://en.wikipedia.org/wiki/ice_age... so go there and read more if u want\n\nhere is more reading on ice ages\nhttp://library.thinkquest.org/j001457/fa...\nhttp://www.museum.state.il.us/exhibits/i...\nhttp://www.geologyshop.co.uk/iceages.htm...\ni am not making this up ice ages exist this is the basis to my argument.\n\nthen i said there is ice and water and the same amount of water is here that was millions of years ago again not made up\n\nThere is about the same amount of water on Earth now as there was millions of years ago.\nsource: http://www.dnr.state.wi.us/org/

Global warming is a situation that ius no longer in mans control. Lets face the facts mother nature cant take it any more. The tornadoes in America are a starting sign that mother nature is starting to wear out and she can't hold on any longer.Possible measures are being taken but i presume that we might just have a little over 100 years then this planet goes from one beautiful blueberry into a an ice cold jawbreaker. Lets face the facts we are after all human and will go for the pleasures of life then sit and think about the future. Now i think is a good time to do that thinking part, but we are a little too obsessed with fast cars and like u have stated SUV'S.

Our grand children or at least our great grandchildren will live in a really ugly world filled with violent people. They tend to get that way when food is scarce, and even the larger animals (bears, panthers, dogs, etc) will consider man a rather choice meal since their prime natural resources will be sorely diminished.\n\nThere is a massive domino effect that most do not even consider. The majority of the so called Civilized Worlds live for now, and tomorrow be damned. Or so it seems.\n\nYou and those (including myself) who are concerned, unfortunately do not make up the majority of whom it requires in stopping the global warming process (or slowing it down). Sad stuff. It really is.

if there was any thing in the world i would change is palution b/c....palution tis causing globle warming..and end the coppkle hunders of years mabe not even that these iceburgs are going to melt and flood the hole plant and every one will die because of it...

Here, 'cause this poor guy said he is bored.\nI would prefer to fight a polar bear.\nAt least they are mammals.. AND can be tamed..\nBut I think we'll be disadvantaged by the weather. Noone can think straight when the air is too cold.\n\nI can't envisage a hairy 8-legged hard-skinned thingy crawling through my throat.\nBut one thing though, how could someone eats when there's a snake wrapping his head and block his mouth from any air least a spider.\n\nHope the less-than-livid imagination could propel your boredom away..\nHave a  nice day!

It's full of lies. Keep in mind, this is the same person who predicted another ice age in the seventies...sorry, i really don't believe in global warming until i get some real facts. After all, how do you think the glaciers melted? The earth had to warm...and that was long before SUV's were around. just my thoughts.

Sorry i dont know the answer but that is sooooooooo sweet! Every creature matters. I watched Planet Earth on T.V last night and it was heartbreaking to see how the Polar Bears are suffering. We need more caring people in this world! Bless ya.

If you mean global warming, it's the scientific observation that the earth's temperature is rising over a period of time This is resulting in polar melting, raising the ocean level and affecting other weather patterns.

No. There are plenty of other theories. The EPA can't and hasn't proven any of their theories. Even a Harvard scientist said that we may just be recovering from a mini Ice Age that caused famine for 400 years (Ireland's potato famine). Who am I supposed to believe? I am not scared, although I do believe it is a good time to start reducing greenhouse gas emissions. Who knows what the cause of "global warming" is? Oh well. Let's just reduce greenhouse gas emissions. There's nothing harmful in that.

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.

I dont know the seriousness in your question but for one, I hate the cold so plz dont suggest puttin the sun off and two, green house gases that TRAP HEAT causes global warming. Not the sun (and yeah yeah, the sun gives off heat, but so does machinary, body heat, lab exothermic reactions, weapons of mass destruction, fires etc)

Stop Smoking\nUse your feet/bicycles rather than driving and polluting the air and causing GLOBAL WARMING.\n\nGlobal Warming has already taken affect in Alaska.\n\nIt's amazing how this generation is considered the "Eco-Friendly Generation" when many of us drive gas-guzzling SUV's

"Are we destroying the earth with technology or is the earth doing business as usual"\nI suggest you track the changes scientists have found in the entire history of the earth, warming, freezing, wet and even effects of smoke from Krakatoa. Then compare what is happening now with pollution and the depletion of the ozone layer and ask the readers to make their own conclusion.

Mission Impossible:  HONESTY AND TRUE REPRESENTATION PLEASE.  As far as issues goes, lets see if the pres. can have the balls to say YES there really is GLOBAL WARMING!!  Not necessarily do anything about it but at least acknowledge it does exist would be nice.

GLOBAL WARMING/THE ENVIRONMENT IN GENERAL\n\nAny and I mean any environmental cause or approach must be grassroots in nature. Having PhD's talk about global warming and having those representing industry interests debunk these present theories is a high level and almost an entirely futile effort. Don't get me wrong, it is great that someone with Al Gore's connections and exposure is getting the word out. However, people are people they want to see results. \n\nYes, the expression is now trite but still true, "Thing Globally, Act Locally". Watching the sky over a city, town or even a more rural area become darkened by smog has local impact, people take note and actually see A PROBLEM. A problem that can measured in terms of air quality or perhaps an AIR QUALITY HEALTH INDEX like the one that the provincial government in Ontario, Canada is in the process of implementing. You can measure results (however small) in terms of air quality and the affect it has on the health care system (those with breathing problems, doctor's visits, etc). It certainly speaks to the advantage of a UNIVERSAL health care system (however, actually implemented) as it actually makes sense to improve the environment as it keeps people healthy (a humanitarian cause) and when health care it publicly funded it affects the public coffers when people become ill therefore it even makes better financial sense to keep the environment a top priority.\n\nPlus any approach must be entire with a complete overall plan (the big picture). Including recycling initiatives, energy solutions (alternatives/renewables can now present a real potential financial threat to the big oil companies and even power companies...), government involvement at all levels, public transit, greener vehicles in general (Hybrid, Hydrogen, Conventional electric, bio-diesel, ethanol), conservation in all energy arenas, ETC!\n\nEconomic viability is the real sell as many of these solutions are just that economically sensible (ensuring we look at the entire picture). Yes as more people use solar, wind and other renewable energy sources the cheaper the technology will get. Two of the newest billionaires have earned a large portion through renewables Solar (India I believe) and Wind (China I believe). Yes in many ways developing nations and economies will be the first and early adopters of such renewable tech as they are just building much of their infrastructure.\n\nSo what do we all need to do? GET INVOLVED ! Contact your local government about improving your recycling program, contact provincial/state/federal government about the adopting of these new technologies (renewables such as solar/wind), buy gas with ethanol in it and demand it, use and demand bio diesel, buy products with less packaging and demand manufacturers to reduce packaging and to offer a price break as a result. More ECONOMIC VIABILITY! After all energy diversity just like economic diversity is the safest and best bet for good long term results and return on investment.\n\nJoe...\n\n\nKEEP IT UP MR. GORE THE POLAR BEARS NEED YOU FIRST **GRIN**.

I concur with answerer 2 and have been reading a lot in the news on the internet and seeing alot on television about it including the information she cited about the polar bears. You see, due to global warming the pack ice in the arctic forms much later than usual. This means seals do not haul themselves out onto the ice as soon as they used to, which in turn means polar bears can't kill and eat them when they are hungry. Also, the pack ice retreats much sooner than normal, and again this means a polar bear cannot fatten up for the summer.\n\nPolar bears are attempting to swim much longer distances than they are capable of in order to find food. They drown. A marine biologist interviewed on the TV said in decades of scientific research this is the very first time he'd ever heard of a polar bear actually drowning.\n\nYou see global warming affects arctic environments much more acutely than temperate ones. Even a few degrees of change in the average temperature can spell disaster for the wildlife there.

Nice try..! But there are no polar bears at the South Pole or in all of Antarctica. Try again, dude.
