Most global warming skeptics are ignorant about many things when it comes to that which they deny, this study not withstanding.

Whereas these folks seem to judge the veracity of global warming research based on daily weather patterns in their immediate location (!), the fact remains this subject involves highly complex and sensitive matters that go way beyond whether or not it happens to be inordinately cold in city/state/region "X" of the country. Ocean currents play a huge part in this complicated equation and as the study points out, it doesn't take much to skew the balance of seawater salinity (due to global warming) to significantly alter the direction of currents.

And we already know the ocean salt balance is changing. Weather patterns are already likely changing as a result.

But not to worry, it's all just cyclical, or due to sun spots, or something.... Let's get back to focusing on truly important things, like tax cuts for the wealthy.
