How far along are we with machines that suck CO2 out of the air?

  An engineering solution that is incredibly cheap was invented in 1980. https://en.wikipedia.org/wiki/Iron_fertilization https://en.wikipedia.org/wiki/Iron_fertilization "Give me half a tanker of iron and I’ll give you the next ice age." - John Martin Iron deposits occur naturally from Volcanic eruptions. It produces huge phytoplankton blooms which create huge fish blooms later. It also drops CO2 like crazy. UN banned all study of this process in 2008: https://www.nature.com/news/2008/080603/full/453704b.html https://www.nature.com/news/2008/080603/full/453704b.html Scientists have since gone rogue and done large scale studies anyway to prove it's safe, like this in 2012: https://www.theguardian.com/environment/2012/oct/15/pacific-iron-fertilisation-geoengineering https://www.theguardian.com/environment/2012/oct/15/pacific-... Now the Canadian government appears to be prosecuting the founder. https://www.theglobeandmail.com/news/british-columbia/ocean-fertilization-experiment-loses-in-bc-court-charges-now-likely/article16672031/ https://www.theglobeandmail.com/news/british-columbia/ocean-... And now they are they are trying to do the same thing in Chili and the mainstream media is fighting it: https://www.nature.com/news/iron-dumping-ocean-experiment-sparks-controversy-1.22031 https://www.nature.com/news/iron-dumping-ocean-experiment-sp...
