The Revenge of Gaia: Why the Earth is Fighting Back – and How We Can Still Save Humanity (2006) is a book by James Lovelock.

Some editions of the book have a different, less optimistic subtitle: Earth's Climate Crisis and the Fate of Humanity.

[1] Under future global warming, increasing temperature may stratify the world ocean, decreasing the supply of nutrients from the deep ocean to its productive euphotic zone.

Consequently, phytoplankton activity will decline with a concomitant fall in the production of dimethyl sulfide (DMS).

However, researchers simulating future oceanic primary production have found evidence of declining production with increasing ocean stratification,[2][3] leaving open the possibility that such a mechanism may exist.
