LiveScience: Squid could be in trouble as the oceans grow more acidic, new research finds.
As humans pump carbon dioxide into the atmosphere, the oceans absorb about a third of the greenhouse gas. This buffers terrestrial creatures from even more extreme effects of climate change — without the oceans, Earth’s atmosphere would contain far more than the approximately 400 parts per million of carbon dioxide that it does today. However, the dissolved carbon dioxide makes the oceans more acidic, possibly affecting…
