Global warming? Ice Age? I'm so confused. Is the world going to get warmer or colder? It's as if someone is trying to scare me out of my money so they can g

  The theory: Warming -> artic ice melts -> reduces salinity of north atlantic -> stops "atlantic conveyer" (which bring warm water from southern hemisphere) -> mini ice age for Europe at least. "The latest climate models predict the overturning circulation will slow down as greenhouse gases warm the planet and melting ice adds freshwater to the ocean. "Warm, freshwater is lighter and sinks less readily than cold, salty water," Willis explained. For now, however, there are no signs of a slowdown in the circulation. "The changes we're seeing in overturning strength are probably part of a natural cycle," said Willis. "The slight increase in overturning since 1993 coincides with a decades-long natural pattern of Atlantic heating and cooling."
