Research performed at Stanford and Oregon State Universities suggests that ocean fertilization may not be an effective method of reducing carbon dioxide in the atmosphere, a major contributor to global warming. Ocean fertilization, the process of adding iron or other nutrients to the ocean to cause large algal blooms, has been proposed as a possible solution to global warming because the growing algae absorb carbon dioxide as they grow.

Today, the New York Times reports on such a pilot experiment involving 112 homes in the Seattle area. The project by the Pacific Northwest National Laboratory of the Energy Department, showed that ‘if households have digital tools to set temperature and price preferences, the peak loads on utility grids could be trimmed by up to 15 percent a year. Over a 20-year period, this could save $70 billion on spending for power plants and infrastructure, and avoid the need to build the equivalent of 30 large coal-fired plants.’

Giant glaciers formed about 90 million years ago when alligators thrived in the Arctic, overturning the belief that all ice melts in a "super greenhouse" climate, researchers said on Thursday.
The study, based on organic molecules in ocean sediments and chemicals in ancient fossil shells, indicated there were ice sheets in Antarctica during parts of the Turonian period, one of the warmest times in history when dinosaurs roamed the planet.
