Actually the 'new ice age' and 'global warming' theories are the same thing. The overall theory is that global warming will cause a fair amount of the ice caps to melt which will cause a lot of fresh water to enter the oceans reducing the overall salinity.
There are huge underocean currents called the conveyor belt which circulate heat around the planet, they rely on a difference in salinity to work. When the oceans get diluted they will stop moving rather abruptly.
The conveyor currents are responsible for bringing warm water to places like England and Australia, without the warm water coming in they will freeze, resulting in an ice age for most of the planet.
It will take many thousands of years to rebalance the salinity and get the conveyors moving again. If we damage the ocean's currents we're pretty much hosed.
The popular media never explains anything in any detail so it's easy to get the idea that these two ideas are unrelated and just scientific fads rather than a coherent idea that has survived several decades of research.
