You know that evil, man-made global warming? Yea, well, it doesn’t look like it’s all our fault after all…
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.”
