Reason Of Global Warming

[oxcricworm]

Me, i think its a combo of all those reasons. Atom bomb tests arent exactly pollution friendly (understatement), but every day all the cars/trains/buses/people farting/planes does a lot more damage. It probobaly is a cycle, but i think its a highly speeded up one in terms of previous ones. In the face of this crisis there are also solutions around. The ideas i like best are:

 
Algae Breeding. This idea means that scientists breed algae which produces ozone on the sea.
Multi Story Gardens. The idea is to make artificial gardens on several stories in big cities.
Fake Clouds. Guess....

Our atmosphere is infact cleaner now then it has been in years past. Today cars, factories ect. are required to abide by more polution control laws then ever before. If this is true then why are we seeing effects of global warming?

There are many scientist who do not believe polution in our autmosphere is causing a "green house effect". But the lack of polution as to 50 years ago is alowing more of the suns reys to pass through the ozone layer.

You are aware that the greenhouse effect is what keeps the heat in right? Hence the colder winters and warmer summers. Who are these some scientists and how many are there?

The ozone layer could be depleting but our climate is definitely different than it used to be 50 (or 60) years ago and before cars it wasn't like this.

The green house effect on the earth is a theory. That is not to say the green house effect as a whole is a theory, just that it is the reason for global warming.

Below is an example of the green house effect. Notice the suns rays and how they pass through the polluted ozone layer and become trapped.

However there are those that believe just the opposite happens. Instead of the suns rays passing through the pollution and becoming stuck, they never make it through in the first place.

These scientists believe that because there is less pollution in our atmosphere then there has been in years, more of the suns rays are able to pass through our ozone layer and heat up the earth.

I think that global warming is a load of bananers. The earth could just be restoring its normal state from a drop in temperature froma former ice age. Another thing that bothers me is when Global warming is claimed to be causing the polar ice caps to melt.if this happened then the oceans would just be flooded-but with EXTREMELY cold water so the earth's temperature would just decrease.

Not really. If they melted then they'd be at above 32 degrees, or around there. But a lot of sea water is at or below that level all the time. but then there wouldnt be any ice that would be cooling us down.

While i dont necessarily believe wholly in global warming i definitely think that something needs to be done to start cleaning up the earth, since its gotten quite bad.

if global warming is the event that brings necessity to making cleaner fuel and better energy, then so be it.

We've had plenty of Ice Ageis before it's part of the evolution of earth.
Possibly why Dinosaurs became extinct.

Global warming does not exist, and if it does it's small. Think about this: we fart a lot, and if the o-zone layer was going to be messed up, that would do it on its own. Dinasours farted too, and they definitely would have destroyed the crap out of the o-zone layer. But the thing is, it doesn't get ruined at all.

start using bicycles i cant now coss i got no right leg ubt i would like to use one

As our parents and teachers say..

Greenhouse gasses altogether are eating our ozone layer and heating up the earth with the warm air masses. Car emissions and smoking, coal electricity and drive thrus' aren't helping either.

As you can see in recent studies is that the polar ice caps are melting fast over the years. Basically after an amount of time the caps will apparently melt completely and screw up the whole weather system. Once all this happens, there will be unexpected floods, tornadoes, rain, and cold. Scientists believe that it could be a matter of 50 years when the world will..

Fail.

ok... the simple fact is... we are due for an ice age... they happen ruffly every thousand years... (according to geologists)
we havent had one... for over 2000 years... which is "odd"...

and we arent speeding up the process... we are slowing it down....

due to all of the electrical devices that we use... (electricity makes o3 which is ozone...which breaks up almost as soon as it is formed...)
we are keeping the earth COOLER! than it ever has been... so the problem for us will be AFTER global warming... when global COOLING happens... because it will once again... last LONGER... than it has ever lasted... the reason we are prolonging our "global warming" is because since we are keeping it cooler... longer... we are making it so that the ice doesnt melt... which will cause the oceans to stagnate... and get even hotter... and then once it reaches a certain temp... it will start to cool down again... and it has done this every 1000 years or so up until "man" its not new... its not fiction... it happens...

but dont worry about it... as we "theoreticaly" have another 300 years before we start having issues... our only real issue now is that hot places are now slightly cooler... (+-10 degrees)
and our cool places are now warmer... due to this system that makes the planet hospitable to life... if it didnt cycle... we would be effed...

(the thing that might kill us... is the fact that when it gets warmer... the oceans will have a lesser co2 concentration (it will loss some of its ability to store co2...)
and co2 is a greenhouse gas...
its also poisonis in big enough doses... but nuclear bombs and etc... couldnt TOUCH the planets natural system for keeping us alive... (the sun does about 100x more damage in a single day... than a nuclear bomb does... however we have a special force field thx to our rotation... that keeps the solar winds from making our planet look like mars...)

that is all... i hope you understood atleast most of this... and look it up dont take my word for it but it is all true :"P

[ti.teg.tnod.I]

I've changed my mind, I don't know what's up with "global warming" I don't know if it's really happening but it's probably just a natural occurence.

Ozone doesn't break up almost as soon as it's formed...and not all forms of electricity form ozone, in fact I don't know a form of electricity that forms ozone.
The ice age theory sounds like bull considering we've been around well over 5000 years...
Nuclear bombs, nuclear radiation, it could do a lot more damage than the sun considering our ozone layer (among other layers) helps shield us from the rays (NOT our rotation). Nuclear bombs leave nuclear radiation that could last for years. (http://en.wikipedia.org/wiki/Chernobyl_disaster http://en.wikipedia.org/wiki/Chernobyl_disaster_effects)
Mars is further away from the sun hence frozen, and Mars rotates too.

[Dijasom]

its not the rotation that causes our "shield from the sun" its our magnetic field  which is caused by our certain rotation etc.

as well as all forms of electricity in contact with oxygen form o3 (when enough oxygen is present...*but it has to be an open spark*)
that is why we have lightning storms (that weird smell during that rainy thundery days... that's o3 *ozone*)
such as a toaster,cars and various other electrical appliances...
also due to the makeup of our air o3 breakdown almost instantly down at our level due to clorine... clorine is one of the leading causes of ozone breakdown.... (why i don't know... since its heavyer than air... but i am assuming somehow... during some manufacturing processes it some how gets up into the atmosphere?

the best info to look into for global warming... is by looking into the past :-\ http://www.esd.ornl.gov/projects/qen/nerc130k.html
we are quite a long ways off for our next full on Ice Age... but a climate shift is what i was talking about (however i may have said it i was slightly off in my previous post...)

there is quite a bit about this debate that is wrong or at least outdated information. for example 279 said that the water would need to get to 32 degrees for the ice to melt. unfortunately since the ice in the north and south pole consists of salt water its freezing point is lower about 25-27 degrees which means it only needs to rise above that point for the ice to melt.

on the first post the premise that nuclear explosions affect the ozone, is correct they very much do they release massive quantities of CO2 and other green house gasses. however they are not the only contributing factor, and are not whats causing the most harm.

someone else said that cows are the biggest contributing factor and this is correct, however what does the most damage is cow dung. as it dries it releases large quantities of methane and CO2.

my last point was that someone was arguing that car standards are much stricter now then ever before so why are we not seeing results? the answer is that most green house gasses have a incredibly long half life, meaning that the gasses from 50 years ago are still arround plus whatever we have added since. it will take a considerable amount of time to see any results from a small decrease. what would be needed is a dramatic change, and even then  the change wouldn't be noticed for some time.
