Lovelock's an interesting character for sure. Although the "Gaia Hypothesis" ended up having a few fatal flaws, it stimulated a lot of thinking and discussion in the field of earth system sciences (atmospheric chemists were a lot more interested than old-school geologists and evolutionary biologists, certainly). Much of what Lovelock pointed to can also be viewed as simple chemical and physical buffering, for example the fact that the a pH-buffered chemical solution responds to the addition of acid in a manner that 'pushes back' against increasing acidity. Likewise, a planet with an ocean buffers temperature changes because the oceans can absorb and release heat in response to external forcing. Biological systems can do the same (forests buffer erosion, for example) but this isn't necessarily selected by evolution, it's just a feature of the biologicol-chemical-physical system. Ultimately, the success or failure of an individual species in a forest (due to natural selection) doesn't have much effect on the effects of a forest on the local climate, say. All in all it was a bit of a spiritual-mystical 'Earth Mother Loves You' theme, which is nice but nature really isn't all that forgiving, as it's clear we can tip the climate system into a new mode, one which some forms of life will not have problems with, but which may drive quite a few others towards extinction. Also, the article mentions his discovery of low levels of chlorinated and fluorinated organic compounds in the atmosphere with his improved detector, it fails to mention that Lovelock also stated at the time that they posed no environmental threat, due to their great stability. This isn't too surprising, as the chemistry that led to the release of the halogens into the stratosphere, where they destroyed the UV-protective stratospheric ozone layer, is fairly complex and unusual (ice crystal surfaces playing a big role over polar regions, radical reactions, etc.). https://pubmed.ncbi.nlm.nih.gov/17778601/ https://pubmed.ncbi.nlm.nih.gov/17778601/ Free Radicals Within the Antarctic Vortex: The Role of CFCs in Antarctic Ozone Loss (1991) There's no doubt, however, that Lovelock made many people think about interconnections between apparently unrelated systems and that alone was a huge lifetime success story. Frank Herbert's Dune also introduced many similar concepts to a wider audience, although that in turn was preceded by Yale's G.
