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.

1. continental drifting\n\nVery slow but substantial changes.\n\n2. changes in sun's energy\n\nSuspected to be large, but not yet demonstrated conclusively.\n\n3. variations in the positions of the earth relative to the sun\n\nFairly small effect. \n\n4. volcaic eruptions\n\nLarge observable effects in global temperature etc. \n\n5.greenhouse effect\n\nKeeps the earth about 60 degrees F warmer than it would be otherwise.\n\n6. global warming\n\nIn the last hundred years, the earth has warmed measurably. It is not clear if this is due to human activities or not, but many suspect it is.\n\n7. air pollution\n\nHas increased the ozone depletion at the poles in springtime, which introduces more UV lower into the air column. This might be changing the climate, although it is not known for sure.\n\nAlso blocks sunlight locally near sources of soot. It is not clear how big an effect this has globally, but it might be a cooling factor. \n\nAcid rain produced by S02 emissions has been involved in some deforestation, which has probably had an effect on the climate, but again this is not known for sure.

all the heat from the sun's rays will stay trapped in the earth and it will get hotter, the polar ice caps will melt and we will all be flooded, which in turn will cool us down form the heat, but if u can't swim you're screwed.\nstop pollution and start recycling now!!!

dude educate your self before you make a broad statement like that. please dont be ignorant. 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

Are you a disbeliever in global warming ? No such relation has been found. In a system as complex as weather, one does not deal with one equation but models involving thousands of equations with even more parameters.\n\nThe following link may help prove my point.\n\nwww.maa.org/devlin/devlin_3_99.html

Yes, the earth is running hot because many anthropogenic activities  are taking place and are at the peak level mainly Global warming and Greenhouse effect.\nbec of this phenomena the temperature is rising high and due to this the polar ice inthe polar region is melting soon and due to this activity there will be rise in thewater level there by reduction in the land surface.\nIF THERE IS A WILL THERE IS A WAY. We can try to minimize it but can't fully suceed ! So unless and untill we try the temperature will go on.

are you people seriously still gonna hold on to the lie that global warming is a hoax???!!!???   Wake the f*ck up people!!!   As a geologist who loves this earth and digs around in the dirt all a day,  I have seen first hand the effects of humans on this planet.... and it is horrible... you think you will live through the next ice age... well fire up your SUV's people and keep burning that oil, don't bother recycling, and you just might live to see it...   desalinization is a bad thing people, really, really bad....  don't believe keep on, keep on...  you ruining this place for your children and grandchildren...

Global warming is the opposite of global cooling.  The Earth has gone through at least 3 episodes of cooling/warming.  Where I am sitting now was once under about 1000 feet of ice.  The Earth warmed up enough to melt all that ice -- and this was way before there were any cars or industry (or even people).  Global warming is NOT caused by people living their lives and producing things. People may have an effect on the rate, but we are not the CAUSE. BTW, the ozone layer hole, which expands and contracts, has no direct effect on global cooling/warming.

I believe global warming is more natural than the enviro-Nazis are giving credit for. I believe whole-heartedly that the Earth has gone through this cycle MANY times. While our polution is having an effect, and we should not have unlimited polluting, it does not have the effect of a volcanic eruption and other natural events.\n\nI refuse to be one of those uber-whackos that thinks that we should try anything to force the human race to go back to loin cloths and spears, riding on horseback. But I also do not believe we should dump and spew everything back into the environment without thinking of the effects. There has to be a happy medium.\n\nI do not really know, as even the scientists do not really know, if we are still moving away from the last ice cycle, or we are past the opposite point and we are moving back towards another ice age. In any case, we need to try and understand it more, and the effects of everything more.\nGood question though.

C for sure.\nMy but didn't this question get some folks hot and bothered. \nMay I point out that yes the plants are using the co2. Meanwhile, we silly homo saps are, while busily pumping hydrocarbons and co2 into the atmosphere, blithely burning down, chopping down and otherwise doing away with rain forests in South America. We are also draining swamps in Florida and filling them in to build houses, hacking down forests in Africa and other countries for the same reason.  All that means less of those nice green plants to absorb all that CO2.\nNow it is possible that we are just in a between glaciation warm spell. But even if we are, there is still the possibility of pushing that warm up over the edge into something we might not be able to survive.

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.

Suppose observers like Spamfighter are correct, let's see how we can explain the following.\nIf you take ice-core samples from various places around the planets ice-caps you can get trapped air that's hundreds of thousands of years old (650,000, more or less). And, sure enough, there does seem to be a pattern of hot-house gas increases and decreases. So for most of this time the earth has been gaining, and then losing these heating elements. \n\nSo far Spamguard & co.'s assertion seem OK. BUT, and this is a big BUT, something else was happening, and it was happening relatively recently. It turns out that since the beginning of the industrial revolution the amount of CO2 in the atmosphere has come to be 27% GREATER THAN AT ANY OTHER TIME WITHIN THOSE 650,000 YEARS. Of course, if you're so inclined, you can say it's a "pure coincidence" and that there are other more "complicated" factors.

Well the sun is getting hotter and will continue to do so until most of  the hydrogen is converted to helium it will then expand to become a red giant. \n\nHowever the effects of this will be minute compared to processes on the earth, IE its tilt, orbit, and mankind's carbon emissions and of cause the deforestation. It must be remembered that we are in an interglacial period and the earth has been a lot warmer than it currently is. The problem is that the increase in temperature is the largest in thousands of years. BUT, when the last ice age finished the temperature rise in approx 50 years was much higher than our rise in 200 years so it is all relative.\n\nThe "freak" weather conditions on other planets may well be perfectly normal for them, remember at best we have only had probes in regular orbits around the other planets for at best 20 years with the resolution capacity to take images that show them.\n\nThe biggest problem is that although in UK we have large taxes on fuel much bigger than any proposed tax by most over governments, there is no unified effort to get us off fossil fuels, if there was someway of getting me out of my 1.2 litre small car than fine, But whats the point when someone in an other country with a 4 litre car still pays less than me to go the same distance?
