Or #3) makes no sense.

I’m a tad confused about the way to think about higher (to ground/sea level) pacific water currents vs. lower, deeper pacific currents? I’ve maybe read (or heard discussed) that the salinity of the water from the northern hemisphere melting has affected the current temperatures and I was just wondering if you could send me a link or whatnot regarding that process? Does it accelerate or have any affect of the larger El Niño trends/behaviors? Thanks in advance! I’m up late because I can’t sleep and so I googled El Niño, you know, to relax.  Oops.  But it’s helpful to know some of this stuff! Great work and thanks so much in advance
