Ships could be causing Global Warming?
The pollution from ship exhaust make more sulfur dioxide (SOx) than all the vehicle in the world.
What do you think about that.
Answer:
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.
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?
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.

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.
ocean currents, not boats are causing global warming!
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...
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.
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...
