Be scared, scientist warns over climate

A leading scientist in the United Kingdom has claimed extreme weather events linked to climate change are occurring sooner than expected and said it is "appropriate to be scared".

Professor David King, who advised the government on scientific issues for almost eight years, called for the UK to bring forward its climate change targets by 10 years.

"We predicted temperatures would rise, but we didn't foresee these sorts of extreme events we're getting so soon," King told the BBC.
