Now this is frightening!! This is happening all over the planet from every industrialized nation. I am looking forward to the Inconvienient Truth (http://www.climatecrisis.net/)as it will really shine a BIG picture on this exact thing.

The atmosphere is a globally shared natural resource, and this image from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) illustrates the point. A pool of air pollution has spread out over eastern China and then slipped over the coast like water over a dam. A river of haze flows across the East China Sea past the Korean Peninsula and northeastward toward Japan, where it arcs along the western coastline of the island chain before disappearing out of the scene at upper right.

Rapidly developing China is the world’s second largest consumer of energy (the United States is first), and its primary fuel is coal, most of it burned in inefficient power plants that emit large amounts of carbon emissions and sulfur dioxide, which is the precursor to acid rain. Increasing affluence in the country is also giving rise to a vehicle boom. As cities become more and more clogged with cars, skies become more and more clogged with automobile emissions. Scenes such as this one from October 22, 2004, are not uncommon for this region.

With the typical Northern Hemisphere “Westerlies” flowing from west to east across the mid-latitudes of the Northern Hemisphere, the air pollution from eastern China regularly spreads to South Korea and Japan and out over the Pacific Ocean. Trans-boundary pollution occurs in many places across the globe, and most nations are simultaneously sources of pollution for countries “downwind,” and recipients of another country’s pollution.

Indeed, it's a problem that will only get worse. It's interesting. As the climate changes, known wind patterns may change and the pollution could trigger conflicts.

Amazing Photograph also. :Thumb

Isnt the world supposed to end around 2060 from a meteor or something

I agree pollution is a problem but who can control each and every country?

The picture is a little deceptive. How high is that haze in the atmosphere? The article makes it sounds as if it is blowing across Japan like a fog. It's actually much higher up and produces little effect on the ground.

I agree it needs to be controlled, but you and Al are making it out to be more than it is. Remember the Industrial Revolution? Mankind didn't die off from that and they won't die from this. :Nope

While I do agree that China is polluting on a geologically disastrous level (e.g. the level where the natural environment can't recuperate), I do want to state that the photo above is enhanced. The "haze" that is illustrated has been magnified to show the flow using color enhancement, so that you can see the flow with the naked eye. You are not seeing an actual "photo".

Enhanced does not mean faked. The clarification done on that photograph not make it any less valid or alarming.

It is an actual photo that has been post-processed - something that is done all the time in photography. The source data in the picture is still accurate. It wasn't photochopped in.

It has a major effect, read about global dimming.

Indeed. Let us not forget that rain brings al this polluntion to the ground and into our water, food, and skin etc. The marmot population in the high elevations of the coast of BC has been directly affected, with proof, due to this pollution from Asia. This IS affecting us all and these other countries are only mimicing NA and their consumerist ideals. Humankind will destroy itself. That is fine but just leave the planet out of it.

No matter what man or nature does to the planet, the Earth will survive. Before man came along there were countless massive volcanic events and many celestial object impacts that caused much greater climate disruption than man could ever accomplish.

A crater the size of Ohio has just been discovered under the ice in Antarctica (http://www.space.com/scienceastronomy/060601_big_crater.html) that was probably due to the impact of an object 30 miles in diameter. It wiped out nearly 90 percent of species in the ocean and more than two-thirds of vertebrate species on land. I spite of the massive loss of life and damage to the planet the Earth is still here and life is thriving.

The Earth has remarkable powers to heal itself. The small effect that man has on the planet in comparison to the natural occurrences will have no lasting effect whatsoever. Even man will adapt to the changes as will the other life on the planet. That is what evolution is, adapting to change.

Man should strive to affect his environment as little as possible but the only way to have no effect would be to not exist and that is an impossibility. The problem is that some people want no change at all and that is also impossible as even the planet is always in a constant process of changing all on its own.

I agree that we will not have a lasting effect on this planet, but after we kill ourselves and 90% if the indigenous lifeforms on the planet how long will it take to heal? A couple million years, a couple hundred million?

But by then who cares - we're already extinct.

It's not just a matter of what we are doing to the planet. It is a matter of what we are doing to ourselves as a side-effect.
