Caution: Again junk science disseminated by the AAAS!
Reminder: Climate models are largely junk! We can not even forecast local weather accurately for more than 48 hours!
"... Squid are some of the ocean’s most intelligent inhabitants. Capable of clever problem solving, advanced communication, and learning from past experiences, these squishy swimmers’ brains contain a similar number of neurons as dogs. But now, thanks to climate change [???], those impressive brains may be doomed to downsizing.
At the Society of Experimental Biology conference held this month in Florence, Italy, scientists presented early data from a study of bigfin reef squid. They raised the animals for 90 days in one of two water tanks: one with a pH of 8.2, similar to modern oceans, and one with a pH of 7.8, which is the value oceans could reach by the year 2100 [???] under continued climate change. As carbon dioxide levels rise in the atmosphere, nearly one-third gets absorbed into the ocean, causing the water to become more acidic.
After analyzing the squids’ heads with magnetic resonance imaging, the researchers made a shocking discovery: The brain volume of squid raised in more acidic tanks was half as large as their counterparts.
Further analysis revealed that the squids’ brain volume had shrunk the most in regions responsible for visual processing. Since bigfin reef squid rely on their eyes to hunt, the findings help explain a previous observation that this species, when exposed to high carbon dioxide levels for 90 days, showed a 42% reduction in hunting behaviors. ..."
