Do you believe Global Warming exists?

It is certainly true that there have been periods in history that have been hotter than it is now before the rise of the combustion engine and heavy deforestation that ultimately lead to the greenhouse effect. Let me say that the 1.2 degrees Celsius increase that we have observed since the rise of the machine and the human effect on the environment is really insufficient to prove what effect of global warming really is. Additionally, the most abundant greenhouse gas is water vapor (making up about 95% of the abundance of all the greenhouse gases). These two facts basically say that there is no support EXPERIMENTALLY for the theory. Yet the theory is correct: with  a build up of greenhouse gases in all the strata of the atmosphere causes infrared light to reflect several more times off of the earth's surface than it normally would, causing a net increase in thermal energy over long periods of time. I am very much a pro-environment scientist, so I can say without bias that the theory is definitely correct, yet we do not currently know what factors (global warming or something else entirely) we can attribute heat changes to, and therefore, we do not know how much global warming will affect us. Only time will really tell...

>>>>>Do you know anything bout global warming?\n\nYes, quite alot.\n\n>>>>do you not agree about global warming?\n\nThat sentence makes no sense. Resubmit in English.

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.

hmmm, maybe global warming is just divine flatulence?

Global warming is believed to be an average raise in temperature.  Not all areas will experience it (if it even exists).  But the Earth goes through weather cycles (as in the cold cycle when there were glaciers covering the Earth, we are now just entering into the warm phase).  This is my theory.  But, as I said, it will not be total, constant raise in temperature.  Some spots will notice the difference, others won't.  It's an overall average.

You're a fool if you don't believe in global warming.  That is happeneing and vetted by alot of scientists.\n\nNow, the cause of global warming is certainly up for discussion/debate.

Global warming is definately a huge issue.  I don't think any countries are enacting on this issue currently

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, 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.

As partisan and insulting a statement (not even question) as that is, there are a few aspects to be addressed when discussing global warming.\n\nGlobal 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!

Finally someone has come to their senses.  The problem with "global warming" is that you can't prove or test anything!  Its all in theory.   Check some of these sites and read the Crichton novel "State of Fear".

I have been wondering if I would see a global warming question up here.  I thought for sure there would just be a bunch of answer blaming Bush for it.  I am glad to see it hasn't gone that way yet.\n\nThis whole global warming thing is a complete sham.  When I was in school they used to run stories on global cooling, we were all going to be under ice, because all the air pollution was going to block out the sun.  Now its global warming, just more nonsense.\n\nUnfortunately they don't teach you kids much in school nowadays.  The Earth goes through climate changes ALL THE TIME.  I know you have all heard of ice ages, probably only because of the cute little kids movie, but we have had them its really true.  It has also been really, really hot here.  We have been completely covered by ice, we have been without even ice at the poles.  The poles themselves actually flip from time to time.  One day the north pole will be the south pole, it has happened before and it will happen again.\n\nWe can't even come close to attempting to try to affect the climate.  And nothing we can do, can stop, or alter where the climate is going.  If it does in fact get warmer, we didn't do it, and we can't stop it.\n\nYou really need to understand what is behind things like this though, because it is truely unAmerican.   A large part of the world and more unfortunately a small but significant percentage of our own people, simply believe we do not deserve to be the world most powerful country.  And everything they can do, to level the playing field, they will do.  This is simply one of those devices.  There are plenty and there will be more.

I don't believe in global warming. This plant was here before us and will be here after we're long gone.

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

there is no unbias news sorce they are all liberal and it has been proven. but my opinion is it dosent exist. because think about it we are coming out of an ice age. it makes sense dosent 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 dinasor 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, glachiers, ect. 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 freze 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 densly populated as ny city). so our vehicles and combustable engines couldent have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasent but it was because of the cfc's(cloral floral carbons) which broke up the ozone by atatching to ozone molocules. but the cfc's are no longer around. the ozone is healing itself as it is meant too. ther was no real hole only a thining 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 isnt that mutch and while the earth was cooling after beieng 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 dosent mean that the earth will stop having ice ages as it has done by its self for billoins of years. think about it.

NO because of all the new cars and fossil fuel that people are burning. because of that the hi concentration of Co2 in the atmosphere Will result in global warming. In the last 100 years the global temperature has GROWN by 1 degree Celsius. and in the next 50 years or so the temperature Will rise by another 3 degrees resulting in freak weather.

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.
