"Arctic Faces Further Threat From Ocean Acidification"

"Acidification is an additional stress on an ecosystem already under pressure from rapid sea ice loss, study warns."

"The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study published on Monday.

Acidification, blamed on the transformation of rising levels of the greenhouse gas carbon dioxide from the air into carbonic acid in the sea, makes it harder for shellfish and crabs to grow their shells, and might also impair fish reproduction, it said.
