Global warming: Crisis for Earth?

James Lovelock: The Revenge of Gaia is "a wake-up call"
The BBC is to gather expert evidence this week on whether human-induced climate change is a crisis for planet Earth, as 
James Lovelock believes.

The originator of the Gaia concept wrote in his recent book "...the fever of global heating is real and deadly".

He says nuclear power is the only short-term way to provide enough energy without causing more climatic harm.

The BBC has commissioned a panel of scientists to review Professor Lovelock's evidence and opinions.

Panel members include top British experts on the Antarctic, climate modelling, interactions between oceans and 
atmosphere, and sustainable development.

It will meet on Monday and Tuesday, with conclusions and comments reported on Thursday on Radio 4's Today programme and 
on the BBC News website.

Goddess on the edge

We may truly be in grave danger... few of the present inhabitants of the earth are likely to survive beyond the 21st Century
James Lovelock
The Revenge of Gaia, published earlier this year, is the latest in a series of books in which James Lovelock has 
developed the Gaia theory, which takes its name from the goddess of the Earth, or the Earth Mother, in Greek mythology.

The key idea is that the segment of Earth from the bottom of its crust to the top of its atmosphere acts as a 
self-regulating being, keeping conditions suitable for life.

A subtitle for Gaia theory is "the science of planetary medicine"; and in The Revenge of Gaia, James Lovelock argues 
that the planetary patient is seriously unwell.

"In January 2004, Sandy [his wife] and I were invited to the Hadley Centre in Exeter [part of the UK Met Office], and 
that visit made us both aware of the deadly seriousness of the Earth's condition," Professor Lovelock told the BBC News 

"We discussed the rapid melting of ice floating on the Arctic Ocean, and the way that Greenland's glaciers are 
vanishing. We talked about global heating in the tropics and the threat to the forests there, and about the response of 
the great boreal forests of Siberia and Canada to climate change.

Too crowded for Utopia
"It was a deeply gloomy picture; but for me the gloomiest of all things was the detached, almost academic, air with 
which the grim predictions were presented - almost as if we were discussing some other planet, not the Earth."

Professor Lovelock intends The Revenge of Gaia to be a "wake-up call" to spread awareness that "the Earth is truly in 

Nuclear solution

But is he right? Are the Earth's regulatory systems in crisis, with temperatures heading inexorably for a higher level, 
unpleasant and perhaps uncontrollable?

If he is, what should we make of his contention that renewable energy and the traditional concept of sustainable 
development are misguided?

Is he right to say that nuclear fission is the only way to provide humanity with the energy it needs until technologies 
such as nuclear fusion and tidal power can be introduced to a substantial extent? Does "a lack of constraint on the 
growth of population" lie at the root of modern environmental problems?

James Lovelock's genius has perhaps been to bring such threads together into a logical whole.

"He is a superb scientist, an originator of the view of the Earth, including its life, as a complete interacting system 
and an all-round free thinker," said Professor Brian Hoskins of Reading University who will chair the panel.

"I hope we can explore Jim's views on why the problem of climate change is so serious, and see if we can agree that it 
should be a clarion call for positive action rather than the bleak view that some have taken from it."

Professor Lovelock is adamant that his book and his thesis is not defeatist, as some observers have suggested.

"Only those lacking imagination would take the book as a counsel for despair," he said.

"I am hoping that... The Revenge of Gaia will be taken seriously, together with the recognition that we may truly be in 
grave danger and that few of the present inhabitants of the Earth are likely to survive beyond the 21st Century.

"It would be wonderful to have positive and sensible suggestions for civilised adaptation."
