Ok, this is where it gets tricky.
Now there are microbes on surface and biological activity and minerals flowing into ocean. This creates photo-synthesis, absorbs carbon, also the bacteria and mineral-rich fresh water enriches ocean locally (a vast area actually). Increase in bioactivity and fauna, fish, whales. Increase in algae and plankton. All of that is good for the ocean (eg. N. Atlantic, Antarctic), nullifies acidity, and algae increases the ocean's ability to absorb CO2 and methane, as do bacteria which absorb methane.
All this is an unseen aspect, that scientists are just realizing (although they may be interpreting it in a limited way in this article), and may put the brakes on various abrupt climate-change scenarios going around.
More nutrients, algae, and plankton, in the ocean, as a result of fresh water, mineral rich run-off from glaciers, could improve ocean health, absorb carbon, nature could have surprises in store that can - as long as we stop polluting - stall, slow-down global warming. This article at the very least, proves that scientists are unaware of all processes. I think they have interpreted this as bad, but in fact, this could be good news.
But we have to stop polluting and mass factory livestock farming, slow population growth, etc.
