You can almost see the phytoplankton-father talking to the boy: "you take this aguinha be strong, son, it is iron." Yeah, that conversation that Mom used to push the beans in the gorge below also works with these sea creatures. And the added advantage: it can in the future to help combat global warming.

A group of researchers led by Raymond Pollard, the National Oceanography Center in Southampton, UK, has demonstrated that regions of ocean rich in iron and have sufficient amount of nutrients encourage the proliferation of phytoplankton. These unicellular creatures, in turn, can help absorb the carbon from the atmosphere and store it in the depths of the ocean - alleviating the issue that human beings with their industrial activities.

The results of the experiment, called Crozex and conducted in the vicinity of Antarctica, are publishing this week's British scientific journal "Nature." For the first time, scientists were able to quantify with any certainty the increased absorption of carbon due to this phenomenon.

They demonstrated that a region naturally enriched in iron home three times more atmospheric carbon than one without the element. However, also found a difficulty in the future exploration of mechanism: for some reason, as yet not fully clarified, the attempt to "enrich" the ocean with iron does not produce artificially the success of the natural enrichment.

Moreover, they indicate that the numbers, although positive, still fall far short of estimates of "geo-engineering", which proposed using the phenomenon to try to reduce the effects of climate change. According to the group, its numbers have "significant implications" for such ideas, to enrich the oceans with iron. Not enough to impede, but suggest that we must learn more about what happens and how to handle it until the thing becomes practicable.
