Is another ice age on the way?
Scientists in the UK have predicted a mini ice age could take place within the next 15 years - causing winters to be a lot colder than they are now.
But how does climate change come into play? Because the Earth will be cooler by 2030 does that mean we can say goodbye to those climate change targets?
Victoria University's earth sciences professor Dr James Renwick joined Paul Henry this morning.
"I think it is good science but I don’t think I believe in the mini ice-age story. It is about the sun-spot cycle which happens every 11 years or so, the output of the sun goes up or down a little bit."
