Salty lakes now store carbon instead of emitting it

Well, this is a mixed blessing.

The paper, published in the journal Nature, says lakes in northern latitudes with hard, alkaline water are now helping remove carbon from the atmosphere instead of releasing it.

What’s more, climate change itself is exaggerating the effect, said co-author Kerri Finlay of the University of Regina.

”They started off like the soft-water lakes — they were releasing CO2,” she said. “But more recently, they started pulling it in.”
