"A team of researchers from the US, Denmark and New Zealand have discovered a process through which a prevalent biogenic nonmethane hydrocarbon compound emitted by trees—isoprene—forms atmospheric particulate matter (i.e., secondary organic aerosol). The results are published in the 7 August issue of the journal Science.
Aerosols impact human health, due to their ability to penetrate deep into lungs, and impact Earth’s climate through the scattering and absorption of solar radiation and through serving as the nuclei on which clouds form, noted co-author Prof. John Seinfeld from Caltech. “So it is important to know where particles come from.”
Emissions of nonmethane hydrocarbon compounds to the atmosphere from the biosphere exceed those from anthropogenic activity. Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Isoprene is emitted by many deciduous trees, with oaks playing the biggest role. Global isoprene emissions from plants are estimated at more than 500 teragrams each year."

I’ve come to the conclusion that stupid scientific studies cause global warming...
“Professing themselves to be wise, they became fools...”

I seem to recall a flap back in the 80s where Reagan was castigated for saying trees caused pollution, except that he was right because trees naturally emit terpenes.
Cutting down trees causes global warming.
Not cutting down trees causes global warming.
Checkmate.
Let’s all go have a beer. (Oops - may cause global warming...study in progress.)
This is confusing. I thought us reckless humans are the cause of global..climate change...whatever (this pc crap keeps changing everyday).
And when Canada was blaming the US for “acid rain” that was killing their lakes, a researcher proved that the accumulation of pine needles was at fault.
You never heard the MSM retract, but “acid rain” stories died out almost overnight.
Reagan was right!
Texas A&M University has said that for years.
LOL!
Save the environment, chop ‘em all down! We need more good hardwood. :)
trees are evil. michelle will have all the trees on the white house grounds removed.
Also, the trees seem to be slowing down average wind speeds, which hurts our efforts to generate “clean electricity”.
As they joked on the Daily Show, Earth isn’t standing idly by — it’s actively working to kill all humans :-)
Sad, but I think I saw this movie! LOL
Call me crazy, but...I still think it's the sun.
It’s about time to pass laws prohibiting any further studies of what causes global warming. Lunacy prevails.
And the sun causes global warming. The various factors on earth just respond to changes that take place on the sun, and in the earth’s distance and angle in relationship to the sun.
Then, again, maybe not.
Liberalism/socialism/Marxism may cause global warming, too.
Illegal immigration, gay marriage, card check, government run health care, and organic food may be the main culprits in global warming.
I love these "may" articles. Great headlines.
BTW, the earth may end tomorrow.
These enviro-nazis just cant keep their story straight. First they lament the cutting down of trees, then they dont. Then they do. And now they want to change the seasons of the earth....
Bwhahahahaha!!
God would have something to say about that LOL
