In addition to the iron fertilization project, Planktos also has a subsidiary, KlimaFa, which has begun a 10-year project to plant a quarter of a million acres of new forest in Hungary.
In 2012, a controversial iron fertilization project moved ahead off the coast of British Columbia and sparked outrage from the Canadian government, oceanographers, and the United Nations.
George has attempted ocean-fertilization projects before, most notably in 2007, when his plan to dump iron near the Galapagos Islands drew fire from researchers and helped trigger the United Nations moratoria against such experiments.
Mr. George, 62, of Northern California, was previously in the public eye when, as chief executive of a company called Planktos, he proposed a similar iron-fertilization project, in the equatorial Pacific west of the Galápagos Islands, whose purpose was the sale of carbon offsets.
Depending on the assumptions used related to CO2 fertilization, in 2030 the projected impacts of climate change on grain production range from -4 percent to +6 percent, and the effects on crop prices range from -12 percent to +18 percent.
A recently finished project on fertilization based on long-term trials has been carried out in cooperation with six other institutes in Denmark, Finland, Germany, Sweden and Switzerland.
While the impact of fertilization on nitrate export is projected to be reduced with warming in most cases, an additional 13% increase in the total phosphorus export is expected in the worst-case combined scenario compared to the sum of individual scenarios.
As a part of a continuing study on pond fertilization at the Farm Ponds Project, Agricultural Experiment Station of the Auburn University, Auburn, Alabama, the author carried on a year-round experiment during the 1959 crop period.
Nearly all embryos used in such projects come from in vitro fertilization clinics, and research is restricted to embryos up to 2 weeks old.
