Average global temperatures have increased by less than 1C since the Industrial Revolution, but they are projected to increase by up to 5C over the coming century if carbon dioxide levels continue to rise without restraint.

The rapid rise in greenhouse gases over the past century is unprecedented in at least 800,000 years, according to a study of the oldest Antarctic ice core which highlights the reality of climate change.

A Nobel Prize-winning scientist has drawn up an emergency plan to save the world from global warming, by altering the chemical makeup of Earth's upper atmosphere.

One of the major arguments in favour of growing GM crops has been undermined by a study showing that the benefits are short-lived because farmers quickly resort to spraying their fields with harmful pesticides. By Steve Connor

"...US emissions have risen by 15.8 per cent from 1990 to 2004, mainly due to increased consumption of electricity generated by burning fossil fuel, a rise in energy demands...and a rise in petrol consumption..."

The inherently chaotic nature of the Earth's weather system can be summed up by a phenomenon known as the "butterfly effect", which states that the flap of a butterfly's wing in Brazil can result in a tornado ripping through Texas.

In his latest book, the green scientist who dared to cross the Darwinists paints a bleak picture of Earth's future under the ravages of global warming. But, he insists, all is not lost for humanity.

Severe weather around the world has made 2005 the most costly year on record with unprecedented levels of insurance claims on damaged property, the United Nations Environment Programme says.

Sea levels are rising twice as fast as they were 150 years ago and man-made greenhouse emissions are the prime cause, a study by scientists in America has found.

Britain's most senior independent scientist has warned that global warming threatens to ruin the international initiative to lift Africa out of poverty.

The Amazon rainforest is being destroyed twice as quickly as previously estimated, according to a satellite survey of the region.

Arctic sea ice has melted to a record low this month, prompting fears that the entire polar ice cap may disappear within decades.

A record loss of sea ice in the Arctic this summer has convinced scientists that the northern hemisphere may have crossed a critical threshold beyond which the climate may never recover.

The Kyoto treaty's attempts to curb man-made emissions of greenhouse gases are being undermined by extra carbon dioxide released naturally from the ground as a result of climate change.

An unprecedented warning as global warming worsens.

People who use mobile phones regularly in rural areas are three times more likely than city dwellers to suffer from brain tumours, a study has found.

Nearly two-thirds of fish species in the North Sea have moved further north in search of colder waters because global warming is driving sea temperatures higher.

One of Britain's most eminent scientists has attacked President Bush for acting like a latter-day Nero who fiddles while the world burns because of global warming.

Scientists have found the first unequivocal link between man-made greenhouse gases and a dramatic heating of the Earth's oceans.

Global warming might be twice as catastrophic as previously thought, flooding settlements on the British coast and turning the interior into an unrecognisable tropical landscape, the world's biggest study of climate change shows.

Blisteringly hot summers similar to the one in 2003 when thousands of people in continental Europe died of heatstroke will become commonplace because of climate change, a study has found.

Polar bears could be decades from extinction, a survey into global warming has found.

They were the first animals with backbones to walk on land. They witnessed the rise and fall of the dinosaurs and were present at the birth of a bipedal ape who went on to become the most destructive species the planet has ever known.

A milestone study of British birds, butterflies and wild flowers has revealed the strongest evidence yet that we are on the verge of a mass extinction of global wildlife - the sixth mass extinction in the history of life on Earth.

A quarter of known land animals and plants, more than a million species, will eventually die out because of the global warming that will take place over the next 50 years, the most important study of its kind has concluded.

For years, the drugs industry has grown fat on a myth - the false belief that all drugs will work on just about everybody.
