The author's bio is pretty fucking redpilled.

> In an article in the scientific journal Nature (February 1988; 331 (6157): 570ff.), John Gribbin was the first scientist to publicly suggest that the upcoming greenhouse effect might be reduced by adding large amounts of soluble iron compounds to the oceans of the world as a fertilizer for the aquatic plants.
> Martin's famous 1988 quip four months later at Woods Hole Oceanographic Institution, "Give me a half a tanker of iron and I will give you another ice age",[6][7] drove a decade of research whose findings suggested that iron deficiency was not merely impacting ocean ecosystems, it also offered a key to mitigating climate change as well.
Who wants to crowdfund a fimbulwinter by purchasing a tanker, fuel, a crew, and lots of ferrous sulfate? Does anyone have a boat?
