There has been a recent increase in articles about using massive scale engineering projects to stop the threat of global warming. The linked article there talks about how it is time to get serious and start pushing these ideas through. Of course we still have to stop CO2 emissions, all while not using nuclear power. Keep the good ideas flowing.
I have touched on geo-engineering before here. The idea of intentionally trying to tamper with the Earth’s climate while not fully understanding what is going on is incredibly rash and foolish. One of the older ideas is to put vast quantities of iron into the oceans as a fine dust. The idea behind this is that algae in the oceans is limited only by the iron content available. It has been shown that adding iron does in fact increase the algae, but the idea took a massive blow due to a recent volcanic eruption in Alaska.
In 2008 the volcano erupted and the ash was very high in iron content. It happened that a storm was in the right place at the right time and carried the iron heavy ash out over the ocean where it was spread out over 1.5+ million square kilometers. This did trigger the expected bloom of “ocean productivity event of unprecedented magnitude.” The problem was the amount of CO2 absorbed was still tiny and had little impact.
This shows that to make a difference this iron seeding of the oceans would have to be done on an enormous scale to have an impact. So expect plans for such events to be put forward as that would still be cheaper and have less of a “carbon impact” than some of the ideas like building giant mirrors in space to reflect energy away from the Earth….. Here is the carbon footprint for the space shuttle. It doesn’t directly generate CO2, but the energy budget is very large and CO2 is generated in each step along the way.
If you think that understanding the climate isn’t important, just think about that idea for a minute.
