Study: climate change is deleteriously impacting marine life

This article discusses how radical Arctic change is bringing spawning cod into new northern waters. A research paper was published last summer that showed how the northern Barents Sea is about to shift from an Arctic to an Atlantic climate.

This article discusses Australia’s Great Barrier Reef. People living near the Great Barrier Reef are deeply worried about its future, and scientists say it’s time for the government to listen.

This article discusses how octopuses may go blind as climate change sucks oxygen out of the ocean. Turning light particles into visual information is hard work, and your body relies on oxygen to get the job done. This is true whether you walk the land on two limbs or swim through the sea with eight. In fact, according to a recent study in the Journal of Experimental Biology, the amount of oxygen available to marine invertebrates like squids, crabs and octopuses may be far more important to their vision than previously thought. In the study, published online April 24, researchers saw a significant drop in retinal activity in four species of marine larvae (two crabs, an octopus and a squid) when the animals were exposed to reduced-oxygen environments for as little as 30 minutes.
