Researchers link ocean organisms with increased cloud cover and potential climate change

l," said Nenes. "You would normally expect to see a change of a couple of watts."

The Southern Ocean is ideal for study because it is largely untouched by pollution and has relatively steady temperature and meteorological conditions during the seasons in which phytoplankton blooms appear. "This seems to be one of those rare regions in the globe where the biology really takes over," Nenes explained. "That allows us to see strongly the impact of biology on the clouds."

As a next step, Nenes would like to examine other areas of the globe for similar activity. "There are a lot of areas that have intense biological activity, so with time we are going to explore more regions to see if this is a widespread phenomenon. Chances are that we will see this in other places," he added.

Nenes and Meskhidze used data from satellite observations to estimate the amount of chlorophyll in the ocean, the emission of isoprene and its connection to cloud formation. Before this new mechanism can be incorporated into global climate models, however, it will have to be confirmed by field experiments.

Atmospheric scientists believe that by blocking sunlight, increased cloudiness has up until now partially mitigated the effects of global warming. The role of oceanic biology on cloud formation could therefore be a major factor in controlling global climate, and the new mechanism identified by Nenes and Meskhidze may make it even more important. This effect needs to be better understood, Nenes noted, because anything that can change global clouds can dramatically alter the impact of greenhouse gases on our changing climate.

"It shows that there is still a lot we need to explore to better understand the delicate balance in nature," said Meskhidze. "It will require the cooperative efforts of researchers from many different fields to identify the chemical components in these aerosols, to estimate the amounts of this and other potentially impo
