Full to bursting

摘要

Rising levels of carbon dioxide will dump even more water into the oceans. The lungs of the planet, namely green-leafed plants that breathe in carbon dioxide and breathe out oxygen, also put water vapour into the atmosphere. Just as people lose water through breathing (think of the misted mirror used to check for vital signs), so, too, do plants. The question is, what effect will rising concentrations of carbon dioxide have on this? The answer, published in this week's Nature by Nicola Gedney of Britain's Meteorological Office and her colleagues, would appear to be, less water in the atmosphere and more in the oceans.
