The three papers in this issue of Climatic Change (Kirchner, 2002; Kleidon, 2002; Lenton, 2002) are probably the most concentrated effort in recent years by several prominent theoreticians of the biosphere to set forth their views on the current status and future of Gaia theory. (Also see the forthcoming volume by M.I.T. Press of the proceedings from the Second Chapman Conference on the Gaia Hypothesis, Valencia, Spain, 2000.) The three papers offer strikingly different renderings. Axel Kleidon… Expand
Developing the Gaia Theory. A Response to the Criticisms of Kirchner and Volk
This paper is a response to the recent criticisms of Gaia theory by Kirchner and Volk, in this journal (Kirchner, 2002; Volk, 2002). As noted by Kirchner, there is a need for more dialogue on thisExpand
The Gaia Hypothesis: Conjectures and Refutations
TLDR
Gaia theory predicts that organisms alter their environment to their own benefit, but throughout most of the surface ocean, nutrient depletion by plankton has almost created a biological desert, and is kept in check only by the nutrient starvation of the plankton themselves. Expand
Thermodynamics and environmental constraints make the biosphere predictable – a response to Volk
TLDR
I do not think that Volk makes convincing arguments that contradict MEP, although I certainly agree that there is a lot more work to be done to fully recognize the great importance that thermodynamics and MEP play in shaping the Earth’s biosphere and its evolutionary history. Expand
Beyond Gaia: Thermodynamics of Life and Earth System Functioning
Are there any general principles that govern the way in which life affects Earth system functioning? Most prominently, the Gaia hypothesis addresses this question by proposing that near-homeostaticExpand
On the homeostasis and bistability on a Gaian planet
Abstract Geochemical disequilibrium of Earth's atmosphere is a sign of life. The fact that Earth's atmosphere is just right for life led Lovelock to propose the Gaia hypothesis: life itself regulatesExpand
Lovelock ' s initial hypothesis
  • 2018
The Gaia hypothesis is an ecological hypothesis proposing that the biosphere and the physical components of the Earth (atmosphere, cryosphere, hydrosphere and lithosphere) are closely integrated toExpand
A century of biodiversity: some open questions and some answers
The study the biodiversity is not just an attempt to understand the differences or similarities between species, habitats or genomes. It also includes an understanding of how nature regulates theExpand
Life on Earth is hard to spot
The triumph of the Gaia hypothesis was to spot the extraordinary influence of Life on the Earth. ‘Life’ is the clade including all extant living beings, as distinct from ‘life’ the class ofExpand
The properties of organisms are not tunable parameters selected because they create maximum entropy production on the biosphere scale: A by-product framework in response to Kleidon
TLDR
It is argued that biological effects on environmental entropy production can be expected to include both positive and negative examples, because these effects are merely by-products of the actual processes that are selected for by evolution. Expand
A Response to Kirchner and Volk
Richard Feynman, arguably the greatest physicist of the last half-century said: ‘Anyone who claims to understand quantum theory probably does not’. The same, although for different reasons, is trueExpand

The Gaia hypothesis of Lovelock states that life regulates Earth's functioning for its own benefit, maintaining habitable, or even optimum conditions for life. But what is beneficial? What is goodExpand

The idea that living things and the atmosphere, oceans, and soils comprise an interactive, self-regulating system-the Gaia concept-was first proposed nearly thirty years ago. Since then researchersExpand
The Simulated Evolution of Biochemical Guilds: Reconciling Gaia Theory and Natural Selection
TLDR
Simulations of Gaian emergence based on an artificial-life model involving genetic algorithms and guilds of simple metabolizing agents illustrate that standard individual-based natural selection is sufficient to explain Gaian self-organization, and help clarify the relationships between two key metrics ofGaian activity: recycling and regulation.

TLDR
The Gaia hypothesis advances three central propositions: that biologically mediated feedbacks contribute to environmental homeostasis, that they make the environment more suitable for life, and that such feedbacks should arise by Darwinian natural selection. Expand
