Daisyworld is the name of a model developed by Andrew Watson and James Lovelock (published in 1983) to demonstrate how organisms could inadvertently regulate their environment [1]. The model simulates a fictional planet (called Daisyworld) which is experiencing slow global warming due to the brightening of the Sun. The planet is populated by ...
James Ephraim Lovelock CH CBE FRS (26 July 1919 – 26 July 2022) was an English independent scientist, environmentalist and futurist. He is best known for proposing the Gaia hypothesis , which postulates that the Earth functions as a self-regulating system.
James Lovelock called his first proposal the Gaia hypothesis but has also used the term Gaia theory. Lovelock states that the initial formulation was based on observation, but still lacked a scientific explanation. The Gaia hypothesis has since been supported by a number of scientific experiments [45] and provided a number of useful predictions ...
The model is designed for use in atmospheric general circulation models, to account for the related climate attribution of the biosphere. [5] A revised version was published in 1996 and incorporates satellite measurements. [6] The Ent Dynamic Terrestrial Biosphere Model is a global vegetation model for use with the Earth System Modeling ...
One of the earliest significant publications on Gaia was a 1974 paper co-authored by Lovelock and Margulis, which succinctly defined the hypothesis as follows: "The notion of the biosphere as an active adaptive control system able to maintain the Earth in homeostasis we are calling the 'Gaia hypothesis.'" [26]
In 2015, several of the scientists in the original group published an update, bringing in new co-authors and new model-based analysis. According to this update, four of the boundaries were crossed: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen). [ 7 ]
Schematic diagram of the anti-CLAW hypothesis (Lovelock, 2006) [1] 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 .
In the mid-2000s, James Lovelock gave predictions to the British newspapers The Independent and The Guardian, where he suggested that much of Europe will have turned to desert and "billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable" by the end of the 21st century.
