  James Lovelock - Wikipedia, the free encyclopedia
In early 1961, Lovelock was engaged by NASA to develop sensitive instruments for the analysis of extraterrestrial atmospheres and planetary surfaces.
To Lovelock, the stark contrast between the Martian atmosphere and chemically-dynamic mixture of that of the Earth was strongly indicative of the absence of life on the planet.
Lovelock is currently president of the Marine Biological Association, was elected a Fellow of the Royal Society in 1974, and in 1990 was awarded the first Dr.

 Gaia theory (science) - Wikipedia, the free encyclopedia
Lovelock's initial hypothesis, accused of being teleological by his critics, was that Gaia atmosphere is kept in homeostasis by and for the biosphere.
Lovelock suggested that life on Earth provides a cybernetic, homeostatic feedback system operated automatically and unconsciously by the biota, leading to broad stabilization of global temperature and chemical composition.
Lovelock responded to criticisms with the mathematical Daisyworld model (1983), first to prove the existence of feedback mechanisms, second to demonstrate it was possible that control of the global biomass could occur without consciousness being involved.

 James Lovelock, Gaia's grand old man - Salon   (Site not responding. Last check: 2007-10-08)
Lovelock is the inventor of the electron capture detector, a palm-size chamber that detects man-made chemicals in minute concentrations.
Lovelock concluded that life -- microbes, plants and animals constantly metabolizing matter into energy, converting sunlight into nutrients, emitting and absorbing gas -- is what causes the Earth's atmosphere to be so, well, lively.
Lovelock and Margulis, considered coauthor of the Gaia theory, soon discovered other bits of "good fortune." Although the sun has strengthened steadily, the Earth's surface temperature has stayed comfortable for life for hundreds of millions of years.

 Peak Energy: James Lovelock’s Gloomy Vision
RealClimate has a post on James Lovelock's "Gaia's Revenge" that looks at both the history of his Gaia theory and the likelihood of his prediction that humanity will be reduced to a few breeding pairs in the Arctic by catastrophic climate change.
Lovelock also points out that the oxygen concentration of the atmosphere has been remarkably stable over the half-billion years since multicellular life appeared in the fossil record, never high enough to explode (doubled atmospheric oxygen would lead to unstoppable continent-scale forest fires), nor low enough to wipe out the animals.
Lovelock’s bold leap was to envision life on Earth as a single unified organism, capable of regulating the environment on Earth for its own well-being, analogous to the way that you or I regulate the temperature and chemistry of our bodies.

 James Lovelock
James Lovelock is one of the world's foremost scientists, best known for developing the "Gaia Theory", which views Earth as a living biological organism.
Lovelock now argues that time is running out, and if we do not work to reverse the damage caused by decades of casual exploitation of a fragile environment, it will soon be too late.
In a profoundly pessimistic 2006 article, Lovelock issued an urgent call for the world's nations to tightly budget their use of the earth's resources, to sustain civilization for as long as possible.

When James Lovelock calls for a massive expansion in nuclear power generation to ward off the worst effects of climate change, as he did in a front-page article in The Independent this week, you have to pay attention.
Lovelock is an independent scientist who grew wealthy by inventing equipment to measure the presence of CFCs, the chemicals used in spray cans and refrigerators that were destroying the ozone layer before they were banned.
Lovelock has always been worried about radical climate change, because the essence of the Gaia hypothesis is that the current composition of the Earth's air and seas-the global temperature regime, the salinity of the oceans, even the proportion of oxygen in the atmosphere-has been shaped over the eons by the activity of living things.

 WorldChanging: Another World Is Here: Lovelock: 'Only nuclear power can now halt global warming'
Perhaps the category for this post should be "a nuclear electric green." James Lovelock, who with Lynn Margulis formulated the Gaia Hypothesis, says that a massive expansion of nuclear power as the world's main energy source is required to mitigate the effects of global warming.
The same issue also includes an article noting that Lovelock was one of the first to warn of the potential disastrous impact of client change, and a piece about significant indicators of potentially catastrophic change: the rapid melting of the Arctic ice sheet covering Greenland, and the extreme heatwave in western central Europe last summer.
Lovelock (in his editorial) makes a compelling case that climate change is happening faster and will be more disruptive than is commonly believed.

 Nuclear reactor - [Sunday Herald]
James Lovelock was the darling of the greens, a pioneer who saw the Earth as a self-regulating entity under threat from global warming … then a wind farm was planned near his home
Initially ridiculed, Lovelock’s famous “Gaia theory”, which proposed that the planet was one living organism with a series of connected systems that controlled climate and temperature, has since become the standard explanation for the changes to our rapidly warming world.
Lovelock devotedly studies the planet and concludes that it’s already too late to prevent the change; the lush, comfortable world we have become used to will disappear very rapidly.

 The Gaia Hypothesis   (Site not responding. Last check: 2007-10-08)
Lovelock defines Gaia "as a complex entity involving the Earth's biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet." Through Gaia, the Earth sustains a kind of homeostasis, the maintenance of relatively constant conditions.
James Hutton (1726-1797), the father of geology, once described the Earth as a kind of superorganism.
Lovelock initially suggested that life itself maintained the composition of the atmosphere, but has broadened the concept to include the whole system of the climate, the rocks, the air, and the oceans as a self-regulating process.

Professor Lovelock won acclaim for developing the Gaia Hypothesis, which suggests the Earth functions as a single organism which maintains the conditions necessary for its survival.
Professor Lovelock said: "In the late 1930s when I was a student we knew that war was imminent, but there was no clear idea of what to do about it.
Professor Lovelock said global warming was "the response of our outraged planet", and the consequences for humanity were likely to be far worse than any war.

 The Gaia Hypothesis
Together with scientist Dian Hitchcock, Lovelock examined the atmospheric data for the Martian atmosphere and found it to be in a state of stable chemical equilibrium, while the Earth was shown to be in a state of extreme chemical disequilibrium.
In that same year, Lovelock began to think that such an unlikely combination of gases such as the Earth had, indicated a homeostatic of the Earth biosphere to maintain environmental conditions conducive for life, in a sort of cybernetic feedback loop, an active (but non-teleological) control system.
Dr Lovelock suggests that Gaia is at work to keep the oxygen content of the atmosphere high and within the range that all oxygen-breathing animals require.

James Lovelock, an independent scientist, author, researcher and environmentalist, has written an OpEd for the Independent Online that is receiving a fair amount of attention.
Lovelock is fairly certain that we’ve passed the point of no return and that the only thing to do now is to maximize the time we have left before extinction.
There’s a part of me that believes the planet is now officially fucked and that we’ve entered into the opening salvo of a runaway greenhouse effect (ie similar to the effect as it occurs on Venus where the interaction of the greenhouse effect with other processes results in feedback cycles).

Lovelock says that nearly all the processes that affect the climate of the earth are now in positive feedback, and he gives six examples of these processes.
Lovelock doesn't try and convince the reader that global warming is happening but takes it for granted, so if you are a sceptic this is not the book for you; and he doesn't go into any great detail about specific issues.
Mr Lovelock also has doubts about any country that needs to resource beyond its borders in a world where civilisation breaks down, yet in the UK we are beginning to depend on French electricity and Russian gas rendering future national secuirity impossible.
