Worsening droughts that come with climate change threaten butterflies' survival in Great Britain, new research shows.

A team of British scientists warned on Monday that if greenhouse gas emissions continue unchecked and droughts become more frequent and extreme, several butterfly species could become extinct as early as 2050.
