The projected rise in global temperatures could be cut in half in coming years if world governments focused on reducing emissions of two harmful pollutants - black carbon and ground-level ozone, including methane - rather than carbon dioxide alone, according to a U.N. study released Wednesday.
The study, "Integrated Assessment of Black Carbon and Tropospheric Ozone,"(PDF) by the U.N. Environment Programme, shows the impact that the two short-lived pollutants have on the environment, compared with carbon dioxide, which can stay in the atmosphere for decades.
"I think what this study does that hasn't been done in the past is look at the contributions to global warming by gases with short lifetimes," said Steve Seidel, vice president of policy analysis for the Pew Center on Global Climate Change...

"You get to keep below these critical temperatures," said Durwood Zaelke, president and founder of the Institute for Governance & Sustainable Development.
The study is aimed at local pollution control officials in municipalities worldwide, particularly in developing nations such as China, India, Brazil and South Africa. Scientists and activists have started to focus on reducing short-lived greenhouse gases in these areas in part because leaders have failed to reach a broader agreement to curb carbon dioxide, global warming's biggest contributor.

Lessee,
1) Hot Air from UN bureaucrats.
and
2) Shutting off Obama’s Teleprompter.
I s’pose. I vote we start with electric and hybrid cars first.
This is the “out” for the alarmists. They propose controlling something that is a lot more feasible than controlling CO2, get some laws passed to do that, and then when the global warming doesn’t materialize, they get to be the heros.
Pollutants?
You mean like Al Gore and Nancy Pelosi?
And it’s also made by the reaction of sunlight on air containing hydrocarbons and nitrogen oxides that react to form ozone directly at the source of the pollution or many kilometers down wind. ....
You mean coal powered cars........
The Useless Nations, hard at work, controlling citizens of the world, while suckling the teats of society.
Interesting. did not know that.
I really don’t see how ground level ozone could cause global warming. That sounds even more far fetched than upper atmosphere CO2 causing global warming.
Reptiles, fish, insects, worms, amphibians and bacteria expel CO2 also......
Make them stop. I keep hearing socialists masquerading as scientists. The sky is falling. The sky is falling. Then the sky doesn’t fall. But they’re back the next day, shouting, “The sky is falling! The sky is falling!” Somebody please make them stop.
At least fix it so I don’t have to pay their salaries.
Doesn’t electric motors generate ozone?
BAN electric cars!
I would be worried more by ozone being a health risk than global warmongering......
Isn't that three things?
1. black carbon
2. ground-level ozone
3. methane
Okay fine ... just speaking of the obvious species...
Thus, all the more proof the idea that CO2 is a pollutant is absurd...
Ozone isn’t all bad. It has many industrial uses. It can be harmful if you breathe it. The electrical odor that you smell coming from the brushes of DC motors is ozone. Some people have ozone generators in their homes.

This is the part I don't get:
"...two harmful pollutants - black carbon and ground-level ozone, including methane..."
Black carbon is soot, and ozone is oxygen. Where does the methane come in? Another shot at ribeyes and ribs?
Methane comes out of the oceans, the ground, and the bottoms of lakes in far larger amonts than cattle or Mexican restaurant patrons.
Globules of frozen methane are on the ocean floor. The frozen tundra permafrost is loaded with methane. Coal mines are continuously venting methane or they will explode at the first spark.....
Oh, and birds. I forgot the birds......;^)
The original diesel engine was designed to run on coal dust.......
