I suppose that’s only a short-term effect.
Long-term prognosis should be the oceans getting saltier because of the rivers carrying salt into the oceans until the equilibrium between salt being carried into the oceans and salt being sedimented at the ocean bed has been restored.
Well, in geological time frames ‘short-term’ can be quite a long timespan.
Are oceans getting saltier? The glaciers that are melting are pure freshwater
EDIT
I’m not an expert but from a quick googling it seems the oceans are getting LESS salty

The issue is not more/less salt in the oceans, but fewer and less reliable sources of freshwater.
Which makes it the perfect time to evolve!

Oceans getting less salt
Rivers and lakes in Canada getting more salt
But I think they were referring to running out of reliable fresh water due to drought
