Long answer: geothermal Management isn't applicable. The issue at hand is global atmospheric temperatures not core/mantel/crust temperatures.
Global atmospheric temp is trending upward due to increased CO2 in the atmosphere. (For the skeptics: this is observed fact, not theory. What is researched and debated is the degree to which man-made CO2 is to blame. To be absolutely clear: we know man made CO2 is to blame, we don't know the exact amount that is our fault e.g. if it's 100% our fault or only 75% out fault). Iron seeding of the oceans does pull CO2 from the air. However it does so by initiating harmful algal blooms. To mitigate/reverse global warming we would need to cause algal blooms on scales equal to the carbon released by all the fossil fuels burned since the 1920s. Depending on the rate at which this is done it could have absolutely devastating affects on ocean biospheres; which, as the planets biggest biosphere, would have negative ecological affects on the planet as a whole. If we attempted to remove that amount all at once it's a definite no go, as other elements would become limiting factors after iron. But even if we tried to just balance our current out put we would cause massive blooms.
We might avoid some of the worse atmospheric effects, hurricanes etc. But we would still risk a massive global scale extinction event and general ecological collapse.
