Bloomberg: Higher CO2 Harms All Marine Life From Corals and Clams to Fish
Higher CO2 Harms All Marine Life From Corals and Clams to Fish

Rising levels of carbon dioxide are harming all forms of marine life because the oceans are acidifying as they absorb the gas, German researchers found.
Mollusks, corals and a class of creatures called echinoderms that includes starfish and sea urchins are the worst affected by the uptake of CO2 by the seas, according to a study today in the journal Nature Climate Change by researchers at the Alfred Wegener Institute in Bremerhaven. The gas forms carbonic acid when it dissolves in the oceans, lowering their pH level.
Creatures that show negative effects from acidification include commercial species such as oysters and cod. Given the pace at which carbon-dioxide emissions are growing, human emissions threaten to trigger extinctions at a faster pace than die-outs millions of years ago, according to the researchers.
“There is a danger that we’re pushing things too fast and too hard toward an evolutionary crisis,” Hans-Otto Poertner, one of the authors, said in a phone interview. “In the past, these crises have taken much longer to develop.”
I will take scientist's opinions over your surface reading any day. Who said kills all marine life? It's not faux news, the real world isn't black or white, and scientists aren't your enemy. We all know fighting, killing, guns, and war all seem to go along with deniers, but don't war on the scientists who are just explaining changes that have consequences.
