Global Warming improves seals love lives

Climate change has improved the love lives of some male seals, at least for the time being, according to Dr. Sean Twiss of Durham University, who studied a gray seal colony on the Scottish Island North Rona for nine years. Rising temps and less rainfall requires female seals to travel further to find fresh water. Away from controlling dominant males, the females accept the amorous advances of weaker males far more often than in pre-climate change days.

Over nine years, Dr Twiss and his colleagues recorded a 61% increase in the number of males contributing to the genetic pool. Dr Twiss said: "These findings show that climate change, whilst endangering many species, could also help to increase the genetic diversity of some species, giving a leg up, or over, to males who normally wouldn't be so successful."
