Any review of geoengineering projects to combat climate change should also include an analysis or description of iron seeding of oceans to promote plankton growth. In addition to sequestering carbon such work results in abundance in the marine food system. A pilot project completed off the Alaskan coast may have resulted in record salmon runs in 2017 as juvenile fish found plenty to eat.

Higher base CO2 level will also soon begin to impact human cognition - it only takes 1000ppm for CO2 to begin to have an impact on our mental performance. If outdoor CO2 levels are high, ventilating buildings will become less effective.
