Environmental scientists want to introduce a new system to prove that adverse weather events are directly linked to climate change to counter global warming sceptics.

Under the new plan, a heatwave or major storm will be linked scientifically to man made climate change immediately after the event to prevent critics from blaming it on natural variations in the weather.

Scientists want to be able to provide proof of whether an event was caused by climate change within three day rather than the current system which can take up to a year.

Dr Friederike Otto said that there was no evidence that Hurricane Sandy was caused by climate change

She said there was also no evidence to link the torrential flooding across the UK in January to climate change

Experts claim that such a long wait for proof means that the general public have broadly forgotten the event and are no longer interested with it.

Dr Friederike Otto of the Environmental Change Institute at Oxford University said: 'We want to clear up the huge amounts of confusion around how climate change is influencing the weather, in both directions. For example the typhoon in the Philippines that dominated the UN climate change talks in Warsaw last November and that many people put down to climate change - it turned out it had no detectable evidence. And the same goes for Hurricane Sandy.'

Dr Otto told The Independent there were many cases where scientists have proved that events have either been triggered or exacerbated by climate change.

She said last year's heatwave in Australia and record flooding in Britain earlier this year.

However, the recent typhoon in the Philippines, pictured, was made worse by man made climate change

Dr Otto said she believed last year's drought in Australia was exacerbated because of climate change

Dr Heidi Cullen, chief scientist with Climate Central at Princeton.

She said:'It's very much like the kinds of risks we see in the health sector, with different levels of confidence in the role played by climate change depending on the situation.

'It's like a weather autopsy. We know from rigorous scientific testing that smoking increase the likelihood of cancer and work out the conditional probability accordingly.'
