Although it is important to control emissions of CO2 to mitigate global warming, atmospheric levels of the gas are also related to how quickly it is removed from the air by the means of land and ocean storage. The micronutrient ...

Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of the ocean's ...

Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting ...

(Phys.org) —An international team of researchers has found evidence in drill core samples taken near Antarctica that adds credence to the iron fertilization hypothesis. In their paper published in the journal Science, the ...
Science is exploring many options for carbon dioxide sequestration in order to mitigate the climatological impact of CO2. One of these is geoengineering: deliberate, large-scale intervention in the Earth's natural systems ...
