Water chemistry reveals a significant decline in coral calcification rates in the southern Red Sea
Experimental and field evidence support the assumption that global warming and ocean acidification is decreasing rates of calcification in the oceans. Local measurements of coral growth rates in reefs from various locations have suggested a decline of ~6-10% per decade since the late 1990’s. Here we...

Experimental and field evidence support the assumption that global warming and ocean acidification is decreasing rates of calcification in the oceans.
