Ships could be causing Global Warming?

Question

http://www.cleanairnet.org/caiasia/1412/article-71368.html
The pollution from ship exhaust make more sulfur dioxide (SOx) than all the vehicle in the world.
What do you think about that.

Don very funny were trying to find a cure to a problem or make better and you want make it worse go work on a cruise ship then

Every time I add cruise ships into the global warming subject people do not say much about global warming because they know maybe the exhaust from the ships are deadly. I believe and they are worried that will not be able to work on cruise liner or go on cruise and worried about jobs. Well if it was fixed then would have worry if it true then worry away. I would not want to go on a ship if it did not have a good catalytic converter on it or the best pollution device installed and some people might be like me.

If we required good catalytic converter on all ships it would help a lot. They reason that ships don't have them is the government is only concerned with there environment around them. This type
of thinking need to stop because wherever you run a car it will affect Global warming. Ships run Marine grade Diesel which if cause a lot of pollution I read as much as 50 times that of a Diesel car per unit. And I read that all ships produce more sulfur dioxide (SOx) than all cars and trucks in the world.

Global warming let 's take look at what happing here.
Why is it advancing so fast lets look some things.
In year 1980 226,545,805 there this many people in USA
In year 2000 281,421,906 this many people USA
Up to 5-19-2007 301,880,165 many people in USA
You start think about all the exhaust fumes going in the Earth atmosphere more pollution more global warming it adds up do math it easy to see.

I missing something here the global warming thing is caused mainly by CO2 . I consider the pollution
or air I breath a bad thing. So I got a little mixed up the global warming is worse than the air we breath is that all. I should worried about global warming not the air I breath . I should be worried about a global warming caused by something other that bad air I breath which might kill me before this global thing is in full force. And I might not be here to experience it anyway is that all or did I miss something.

I have decided this subject does matter any way to me I not in charge of any think releated to this and no one listen to me So ask this subject goes no one cares so I not going care. It just stressfull. Weather there something other in the exhaust fumes causing this or whaterer if population has certain cemicals I glad that the reasearch has been done no is worried what is coming out from the fumes or whatever it don't matter anyway to me. What scary is every thinks every thinks they know what is happeing. So I decided who cares. But if I working on a job my boss has no reason to tell me the working I doing is going to kell me later from the air I breath. Well do expect something to happen like that for us it no different . And as far as the chemicals exhaust fumes.Well I going reasearch somthing I not wast my time.
I can see there is a big problem. We will pay later weather it a golbla warming or a clean air I sorry I got mixed up on how different they are and are not releated.

I think that Every one is running there air conditioner so what's happening is there is a lot of heat emitted
or given off from them air conditioner's to the outside so what happens is this hot air turn is warming the plant.
Not the oceans.

Answer 1

Ships are part of the problem, that is true. But sulfur dioxide is not the cause of global warming. CO2 is. And yes, ships emit a lot of CO2.

Answer 2

In terms of global warming, it's not so much the sulphur dioxide that's the problem but the nitrous oxide and carbon dioxide from burning marine fuel.

Suplhur dioxide is, for want of a better word, reflective and reflects sunlight back into space. When air pollution peaked in the middle if the 19th century there was so much sulphur dioxide in the atmosphere that it led to measurable global cooling. We see the same thing happening after major volcanic eruptions. The last one, Mount Pinatubo in 1991, put so much SO2 into the atmosphere that for the next few years temperatures dipped slightly.

In some ways it's ironic that the Clean Air Acts that were passed in the 50's and 60's resulted in the removal of much of the pollution that was capping global warming.

In terms of CO2 emissions, shipping accounts for about 1% of the anthropogenic total (all transport is 19%, mostly from road transport and planes).

Shipping produces a lot of nitrous oxide, I don't have figures to hand but it's around about 20% of the overall total. Whilst the volume of NO emissions is tiny compared to CO2, it is a far worse gas in terms of global warming - it's about 300 times as bad (more accuratley it has a 100 year GWP of 296).

When everything is factored into the Global Warming Contribution (GWC) equation shipping accounts for less than 2% of the anthropogenic warming.

Whilst this isn't a great deal, it is one area in which a significant improvement could be made and if similar improvements were made in other areas this could add up to a very significant reduction in greenhouse gas emissions.

SO2 and NO not only contribute to global warming but they're hazardous to health and cause respiratory complications and can exaccerbate conditions such as asthma. It would be beneficial to everyone if shipping were to adopt cleaner technologies.

Answer 3

AHHH!!!! Global warming is not influenced by man!!!!!! Sulfur dioxide makes up less than .0001% of the atmoshpere. There is enough atmosphere for every person on earth to have over 2 million tons of air. And to people who are going to post about CO2, can u explain why temperature leads CO2, sometimes by 2800 years after an ice age, like the one we just got out of! The Little Ice Age people, it ended in the 1850's!! Crops were being grown in Greenland by the Vikings until it started in the early 1400's. Do a little research on past climate and it will be easy to find. Man can not change the world temperature. Global warming doesn't exist, the ice is NOT melting, and the world temp. has been decreasing since 1998! So please stop believing in global warming. If u have any questions related to global warming, please contact me at [e-mail]. Thank U!

Oh Yea...It was so cold out today, I forgot that the Earth is warming. When I was in school, we were warned about the coming ice age.
So if we send a few ships to Mars, we could Terra-form the planet? Oh...What's that about not being able to change climates on a planetary scale?

Answer 5

Yes, you certainbly missed something, I think.

What makes things hot? The Sun's rays...Right?
And do some things get hotter than others from the Sun's rays? Sure, you say... Black colored things get hotter than White colored things...We all know that.

Yet...Look at the color of most roofs...All Black.

Look at the color of most roads and highways...All Black.

And you wonder why the Earth is getting hotter??? I wonder why you can't see what you are standing in the middle of...

Answer 6

cruise ships are a huge environmetal problem...from the exhaust the spew into the air to the garbage they dump into the seas (including apparently an occasional passenger)...
I think it helps to reduce fumes EVERYWHERE we can including this industry...

Answer 7

I knew this already. That's why our products that we buy from other countries that are shipped overseas are considered to have fairly large carbon footprints.

Just another industry that needs to get green. It'd be nice to see mega hydrogen engines on these ships.

Answer 8

ocean currents, not boats are causing global warming!
