The weather forecast for this holiday weekend is wildly unsettled. We had better get used to it.

According to the climate change scientist James Lovelock, this is the beginning of the end of a peaceful phase in evolution.

By 2040, the world population of more than six billion will have been culled by floods, drought and famine.

The people of Southern Europe, as well as South-East Asia, will be fighting their way into countries such as Canada, Australia and Britain.

We will, he says, have to set up encampments in this country, like those established for the hundreds of thousands of refugees displaced by the conflict in East Africa.

Lovelock believes the subsequent ethnic tensions could lead to civil war.

Crackpot or visionary, the fact is that more and more people are paying attention to Lovelock, and that he, himself, supports the Intergovernmental Panel on Climate Change (IPCC) - the influential group who shared the Nobel Peace Prize with former American vice president Al Gore for their campaigns on global warming.

Lovelock also says that Margaret Thatcher and the Queen are "sympathetic" to his views.

He has been proclaiming his Gaia Theory for a generation. This states that the Earth is a living, self-regulating system and that by filling its atmosphere with CO2 (carbon dioxide emissions) we have destroyed the balance and overheated the planet. We are in the phase when the thermometer suddenly shoots up.
