Arson attacks under the spotlight

The work of a new team of forensic scientists in the south east could help uncover whether a fire has been started deliberately. The University of Kent at Canterbury has set up a fire investigation unit to examine suspicious substsances and liquids found at the scene of a blaze.

Stop global pollution - pay more for plane travel!

We've got to pay more for our plane tickets if we want to stop global pollution say scientists at the University of Southampton.

They say the best way to stop greenhouse gasses from planes is to make it harder for people to afford plane travel, so prices must rise by at least 1.4 per cent a year for carbon emission levels to fall.

The Scientists add that although the aviation industry is trying to make air travel cleaner, increasing numbers of people flying will lead to increase pollution unless demand is substantially reduced.

"There is little doubt that increasing demand for air travel will continue for the foreseeable future,” says co-author and travel expert Professor John Preston. “As a result, civil aviation is going to become an increasingly significant contributor to greenhouse gas emissions.”

Air travel keeps growing and the atmosphere is starting to notice. Burning kerosene and other aviation fuels that power jet engines and propellers means carbon emissions among other types of pollution is deposited high in the atmosphere, where it contributes to global warming.

The world’s nations have spent years trying to come up with a way to restrain air travel emissions - the University of Southampton scientists say increasing prices maybe the only answer
