German Physical Society (Deutsche Physikalische Gesellschaft – DPG) has made a sceptical statement. „Despite many existing approaches there is currently no known functional method of cooling the Earth’s climate.„
„Integrated Assessment of Geoengineering Proposals (IAGP) is a[nbsp]four year research project,[nbsp](October 2010 to September 2014) and is funded by the Engineering and Physical Sciences Research Council (EPSRC) and the Natural Environment Research Council (NERC). [nbsp]IAGP brings together a broad range of expertise, from climate modelling to philosophy and engineering to public perceptions to conduct an objective, policy-relevant assessment of geoengineering proposals.“

„In this study, we investigate climate response on the time scale of days to weeks to a step-function quadrupling of atmospheric CO2 and contrast this with the response to a 4% increase in solar irradiance.“

„Efficiency of carbon export decreases for increased size of fertilized patch – Lateral supply of silicic acid is critical to blooms in iron-fertilized patches – Carbon export resulting from iron fertilization is minimal“
Another media response to a paper published by Royal Society. „Even though it sounds like science fiction, researchers are taking a second look at a controversial idea that uses futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight and thus counter global warming.“
