What's the mechanism?
Even more, how did the oceans become saltier without me knowing?

You were asleep a long long time?
Oddly enough, GHG have an uncanny ability to be absorbed by oceans, a side
effect of which is increased saltiness, and PH [acidity]
But most salts are derived by runoff from the land over time. So a key
component of AGW besides GHG is also land use. Be it forrest removal, or use
of fertilisers on farming lands ..... both of which tend to increase the
outflow of salts into streams, then rivers, and then into the oceans.
So as yet, Im a little confused about Dr Grat's naysayerness at this point,
but intend to look up his most recent comments and any studies to which he
refers. At this point, it seems to me to not really add up as a reason to
ignore AGW and just believe him that it's a cyclical chgnage in salt content
in the oceans .... for no particular reason but nature wanted it to happen
right now.

Why Is The Ocean Salty?
Science Daily The saltiness of the sea comes from dissolved minerals, especially sodium, chlorine, sulfur, calcium, magnesium, and
potassium, says Galen McKinley, a UW-Madison professor of atmospheric and oceanic sciences.
Pacific Ocean at dawn. Today's ocean salt has ancient origins. As the earth formed, gases spewing from its interior released salt
ions that reached the ocean via rainfall or land runoff.

I doubt the ocean, as a whole, is becoming saltier, but one could imagine
mechanisms that affect the salinity of smaller regions in the oceans.
(I haven't heard that this is happening, though.)
For example, enhanced evaporation would make a region saltier.
Formation of sea ice separates water and salt (the ice is mostly
fresh water), so changes in ice formation/movement and changes
in the downwelling of the residual high-salinity water would
have effects. Changes in precipitation could affect where fresh
water is being added to the oceans, the flip side of evaporation.

CO2 has no effect on salt levels.

Bullshit. Forest fires release salts, logging does not.
There are trillions of tons of potash in the ocean, fertilizers have tiny effect.

CO2 is only one GHG ... but technically I could be wrong about salts here.

You get all of your speech for free, right Bwett?
Trying paying for some instead, read A Short History On Nearly
Everything by Bill Bryson

For those who cannot understand context, make that,
"saltier in the last 50 years?"
And even more interesting, how do the oceans become _less_ salty?

Just offhand I'm guessing that adding some fresh glacial ice sheet
meltwater would do it.

Ya, but he's living on planet Paranormia where it does.
