Squid, “surprise” are going to do well with climate change. (If only it was going to happen).
In the new post-CO2 world, corn and soy may become weeds, but squid may take over the oceans:
Squid will survive and may even flourish under even the worst-case ocean acidification scenarios, according to a new study published this week.
Dr Blake Spady, from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University (JCU), led the study. He said squid live on the edge of their environmental oxygen limitations due to their energy-taxing swimming technique. They were expected to fare badly with more carbon dioxide (CO2) in the water, which makes it more acidic.
No academic could have guessed that squid would have evolved ways to control their own blood pH:
“Their blood is highly sensitive to changes in acidity, so we expected that future ocean acidification would negatively affect their aerobic performance,” said Dr Spady.
Atmospheric CO2 concentrations have increased from 280 parts per million (ppm) before the industrial revolution to more than 400 ppm today. Scientists project atmospheric CO2 — and by extension CO2 in […]

Three amazing things in this story. One that solar cycles might influence the oceans to such an extent that jellyfish plagues are cycling in tune with the sun. Second is that the sun might control food for jellyfish on Earth somehow but have no effect on clouds, temperature or our climate (join the dots that expert climate models don’t). Third is that (briefly) there was actual scientific debate published on the ABC (even if only a few Australians were exposed to it). No one called anyone names, and both sides got to speak (albeit on different channels). Put it in your diary.
A couple of weeks ago on the ABC jellyfish were booming and it was because of climate change:
Jellyfish are causing mayhem as pollution, climate change see numbers boom
RN By Hong Jiang and Sasha Fegan for Late Night Live
…the brainless, spineless, eyeless, bloodless creatures are booming in numbers — and causing mayhem around the world.
Some scientists think jellyfish numbers are increasing as the climate changes — the creatures reproduce well in warmer waters.
Last year, Nick Kilvert of the ABC saw it as a […]

Is James Cook University a grants machine or a research institute?
James Cook University reviews ex-student’s ‘fishy’ findings, by Graham Lloyd, The Australian
Oona Lönnstedt has been prolific, writing alarming papers on microplastics, acidification, and reef degradation. But her work looks like a trainwreck. One paper has been withdrawn, in another it was “found that Lonnstedt did not have time to undertake the research she claimed.” She’s been found guilty of fabricating data on the microplastics study. Now Peter Ridd has pointed out that the photos of 50 Lionfish appear to contain a lot less than 50 fish. Images have been flipped, spun or “manipulated” so the same fish appears more than once.
James Cook has done what any ambitious, money-hungry grant troughing institute would do, a very slow investigation of allegedly corrupt behaviour and a very quick sacking of the honest researcher who threatens to expose them. Any respectable Science Minister would freeze all grants to James Cook until this situation was resolved and reversed.

A map of the sea surface zone that has cooled since 1979 — from 56S – 72S . It’s a pretty big area. Click to enlarge.
For years the IPCC have said that warming would be amplified at the poles. They warned us things would heat up twice as fast, which would melt sea ice. The oceans surface in turn would switch from being reflective white to a dark absorbing deep blue. Enormous amounts of energy would then flow into the ocean instead of being reflected back out to space. The more it warmed, the more it would warm — unleashing a devastating feedback loop.
As the Arctic warmed, the merchants of doom were keen to tell us how how right they were and this was evidence of man-made warming. But in the Antarctic exactly the opposite trend was taking place.
Mike Jonas has done what the IPCC should have been doing — investigating the trends in the Sea Surface Temperature in the polar latitudes with satellite records. In the latitude band from 56 to 72 degrees south the oceans have cooled, not warmed. The models don’t even have the sign of the trend correct. At the latitudes where […]
This should end all the Pacific Island climate claims right here. A new study of over 700 islands for decades shows that even though seas are rising faster than any time in the last million years, somehow no islands with people on are shrinking. This means there are no climate change refugees from any vanishing island. Plus it’s more proof that highly adjusted satellite data is recording sea levels on some other planet.
Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea-level rise. A reanalysis of available data, which cover 30 Pacific and Indian Ocean atolls including 709 islands, reveals that no atoll lost land area and that 88.6% of islands were either stable or increased in area, while only 11.4% contracted.
Look how closely these researchers are tracking the shores. Below on Tuamoto, French Polynesia, scientists can tell you that islets 12 and 14 (see pic) have disappeared since 1962. So we can track roving blobs of sand about 20 to 30 meters across.
No habitable island, none, got smaller:
The researchers reckon that 10 hectares is about the smallest island you’d want to plonk […]
Since 1984 humans have gushed forth 64% of our entire emissions from fossil fuels. (Fully 282,000 megatons of deplorable carbon “pollution”.)
During this time, satellite images show that 24% of our beaches shrank, while 28% grew. Thus we can say that thanks to the carbon apocalypse there are 3,660 sq kms more global beaches now than there were thirty years ago. Yes. It’s that bad.
The encroachment of beaches would mean there is less ocean for fishes. Thankfully sea levels have risen too, so it looks like it will all work out.
This study also produced a handy map of where the sandiest beaches are. Clearly Africa wins (unless you prefer rocks and cliffs).
Sandy beaches (yellow) versus Rocky beaches (black). Percentages indicate the proportion of sandy beaches. Source
Presumbly the paradox of how seas can rise unprecedentedly fast at the same time as beaches are growing will be explained through global currents shifting ominously due to rising CO2 levels. Either that, or the paradox and the study will vanish into a subterranean library — like the deeper Asthenosphere Archive, where they will be converted to magma.
Seriously, though, this study appears to be the first to […]
