Regular freezing winters if the Arctic continues to warm up, scientists warn

The cold and snowy winter that paralysed Britain last month could become a regular feature if the Arctic continues to warm up, scientists say.

If climate change weakens the Gulf Stream, the UK faces a chilly future even as the rest of the world gets hotter.

The warning came ahead of a UK expedition to the Arctic to find out how the world's most northerly sea is changing.
